Review-1 defect (HW-surface/software-filter collision) FIXED: buildHwaccelInputFlags() now delegates to profiles' getInputDeviceArgs() (no divergence); new hwaccelUploadFilter() appends format=nv12,hwupload AFTER software filters for VAAPI/QSV only (NVENC/VT/AMF take system memory); added HwaccelProfileFactory::getProfileForVendor(). #3 vaapi test corrected + 4 coherence tests (downscale NVENC/VAAPI hwupload-ordering, HDR NVENC, QSV device); --filter Hwaccel 139 green. QSV device-key fixed. #4 confirmed (FPM lazy-probe, no boot log — OK). Commits 02606550,e54cf142,f37fc0f9. ⚠️ SCOPE-CREEP (beneficial): commit 4d49d9bc ALSO cleared the other pre-existing errors → phpstan L9 now [OK] 0 errors + phpcs 0 errors. That touched SV-2.8 (ItemRepository is_numeric-guarded casts) and SV-3.2 (WebPortalServicesProvider:295 BookController factory: BookLibraryManager→LibraryManager — was a LATENT RUNTIME FATAL). Those steps' audits MUST account for this. testAddStream* reds remain = pre-existing SV-2.8 test-drift (unchanged). REVIEW-2 2026-07-12: essentially CLEAN — VAAPI+NVENC+libx264-fallback correct (high confidence), collision defect genuinely fixed, tests guard the seam, scope-creep edits all verified correct. 1 finding LOWER-CONFIDENCE/Intel-QSV-only/unverifiable-here (QSV hwupload needs -init_hw_device qsv=hw -filter_hw_device hw + hwupload=...,format=qsv; NOT a regression) → DEFERRED to task #6 (verify on Intel HW; won't write untestable ffmpeg blind). SV-0.1 code+tests DONE for verifiable scope; docs batched w/ wave. SV-0.1/0.2 effectively DONE ✅ (docs pending). - [x] SV-0.2 reconcile hwaccel config RE-AUDIT 2026-07-12: DONE — single source HwAccelConfig::get(); ffmpeg.php+hwaccel.php delegate; no contradictory flags. Regression test added: HwAccelConfigTest(7) green (commit 0a35848a). Pending confirming review alongside SV-0.1. - [~] SV-0.3 isWorkermanContext fix RE-AUDIT 2026-07-12: PARTIAL — impl CORRECT (shared Common\Runtime\WorkerContext::isEventLoopRunning() via Worker::isRunning(); all 4 clients + PluginCatalogService use it; old defined() guard gone). GAP: mandated regression test MISSING. FIX LANDED (ce2d2e04, 2a243857): WorkerContextTest added; branch-selection guard via Webhook seam. REVIEW NO FINDINGS 2026-07-12 → DONE ✅ (docs batched w/ wave). - [~] SV-0.4 replace usleep spin-wait with Channel RE-AUDIT 2026-07-12: PARTIAL + REAL BUG — spin-wait gone, but coroutine gating WRONG: Metadata/Webhook/S3 route to Channel path on isEventLoopRunning()&&!requiresBlockingCurl() with NO getCid()>0 gate → Channel::pop() outside a coroutine returns false immediately = FALSE TIMEOUT while callback pending. HttpClient INVERTED (Channel used only in non-coroutine case where it's invalid). AC requires: getCid()>0 → Channel; else blocking. FIX LANDED (ce2d2e04): all 4 clients gate Channel::pop on inCoroutine(); HttpClient inversion corrected (dead requestAsync removed); TLS blocking fallback preserved. Real coroutine test (wake+clean-timeout). REVIEW NO FINDINGS 2026-07-12 → DONE ✅. (PluginCatalogService SV-4.11 has same latent gap — its step.) - [x] SV-0.5 fix WS reaper + heartbeat timer guards RE-AUDIT 2026-07-12: PARTIAL — function_exists→class_exists fixed (3 sites); WS reaper arms (per-worker repeating); stream heartbeats one-shot (Timer::add(30,...,[],false), storm CAPPED). GAPS: (1) S-F28 WS app-level ping ABSENT (no pingInterval/pingNotResponseLimit, no ping timer → half-open sockets undetectable); (2) heartbeat NOT keyed-per-session/deduped/torn-down on stream end (each request re-registers → bounded accumulation, not the keyed+cancelled AC); (3) tests shallow (smoke test w/ stale comment; no leak test). COMPLETED 2026-07-12: (1) server-side ping timer + onWebSocketPong (Workerman 5.x has no pingInterval); (2) StreamSessionService keyed+deduped one-shot heartbeat timers torn down in releaseStream(), callers delegate; (3) reaper-registration + ping-reap + heartbeat one-shot/keyed/leak tests. phpstan 0, phpunit 85 green, phpcs no new. See Implementer note below. Pending review. - [x] SV-0.6 fix TMDB collections UUID-as-int bug ✅ (commit ad6d6d86) - [x] SV-0.7 supervise marker/intro-detection worker ✅ (commit 46c71440) - [x] SV-0.8 fix path_hash reads + stop re-probing ✅ RE-COMPLETED 2026-07-13 (perf-7): earlier "DONE" (citing non-existent 510c8761, real prior commit 3bfa7d96) was INCOMPLETE — findPathsMap lacked library_id scoping (commit 46463be5 fixed that + a real cross-library correctness bug) but review found a HIGH severity gap: path_hash is NULL for non-deduped types (series/season/image/audiobook) so lookups always missed → duplicate rows every rescan. Fixed f31f34b5 (two-pass path_hash-then-raw-path fallback, every call site threaded with libraryId). 3-round review→fix→re-review cycle, final verdict NO FINDINGS. **DONE.** One honest caveat: the real-DB EXPLAIN/NULL-hash integration tests self-skip in this sandbox (no reachable MySQL) — structurally sound, correctness proven by layered unit tests, CI-green confirmation owed next session. - [x] SV-0.9 fix generateThumbnailBatch timestamp escaping ✅ (commit 1f4bfd3d) + COMPLETED 2026-07-13: batch command-shape half. Escaping fix (1f4bfd3d) had introduced a NEW defect: all per-timestamp `-ss`/`-vframes`/output groups bunched before one shared `-i` → malformed, rendered zero thumbnails for >1 timestamp (latent, no array caller in prod). Fixed via new `buildThumbnailBatchCommand()` builder: each timestamp gets its own `-ss -i ` pair (fast input-side seek) + explicit `-map :v:0` per output; also hardened the return value (empirically confirmed real ffmpeg exits 0 even when every seek is past EOF, so exit code alone can't signal success — now verifies ≥1 frame file was actually written). Real caller wiring evaluated (MediaAssetGenerationJob::generateChapterThumbnails loops N single calls) but deliberately left uncalled — see worklog entry for the 3 reasons (no test coverage on that class, modest win for widely-spaced chapters, per-chapter failure-isolation semantics need their own scoped change). Unit (6 tests, command-shape) + Integration (3 tests, real ffmpeg, distinct-frame-content) added — method had zero coverage before. phpstan/phpcs clean, full Unit suite 5138/0. Commit `d3062086`. - SV-0.9 CLOSED 2026-07-13 — fix-pass re-review returned NO FINDINGS (commits 20dc2370/d8bac2c5). - [x] SV-1.1 memoize/precompute HDR tone-map decision ✅ (commit bbef742c) - [x] SV-1.2 make non-probe ffmpeg calls coroutine-friendly ✅ (commit 6da7dc41) - [x] SV-1.3 move chapter-thumbnail + trickplay to background job ✅ (commit 4317214b) - [x] SV-1.4 correct zscale tone-map graph ✅ RE-AUDITED 2026-07-13: graph was already correct (opencode's `7c7156dc` verdict held); only gap was a missing direct test — added `FfmpegRunnerToneMappingTest` (commit `6a6e5005`). - [x] SV-1.5 implement real libplacebo tone-map mode ✅ RE-AUDITED+FIXED 2026-07-13: opencode's `abad4b46` was WRONG — emitted `peak=`/`input_color_space=`/`input_primaries=`/`input_trc=`/`output_color_space=`/`output_primaries=`/`output_trc=`, none of which exist on the real `libplacebo` ffmpeg filter (confirmed live: `Error applying option 'peak' to filter 'libplacebo': Option not found`). Rewrote using only real options (`tonemapping=hable:colorspace=bt709:color_primaries=bt709:color_trc=bt709:range=tv`), verified by actually running it through ffmpeg with a synthetic HDR source (exit 0). Commit `9ce4db5f`. - [x] SV-1.6 fix subtitle burn-in escaping + VAAPI overlay ✅ RE-AUDITED+FIXED 2026-07-13: opencode's `7a248f40` was PARTIAL — colon left unescaped in `filtergraphEscape()` (and a single escape round proved insufficient; needed DOUBLE application — verified against real ffmpeg), VAAPI filter order was `hwupload,subtitles=...` (backwards — hwupload before the software filter), and `SubtitleBurner` had zero production callers (only reachable via the zero-caller `buildTranscodeCommandWithProfile()`, SV-4.13's removal target). Fixed all three + wired subtitle burn-in into the LIVE per-segment pipeline (`FfmpegRunner::buildSegmentCommand()`/`buildHwaccelSegmentCommand()` + `TranscodeManager::ensureHlsJob()`'s new `subtitle_burn_in_index` option). Commit `a0803f7d`. - [x] SV-1.7 range parser reuse on direct-play ✅ (commit 1862fafb) - [x] SV-1.8 CSRF Origin exact-match ✅ (commit ba3096ba) - [x] SV-1.9 ENOSPC guard on segment cache ✅ (commit 70d99f4e) - [x] SV-1.10 login rate limiter bound ✅ (commit a3a6b35a) — S-W1 complete 🎉 - [x] SV-2.1 stream file-backed responses over relay tunnel ✅ (commit b3e45682) - [x] SV-2.2 pool hygiene: rollback dirty connections ✅ (commit 6bd400ee) - [x] SV-2.3 relay byte-pipe backpressure ✅ RE-COMPLETED 2026-07-13 (perf-7): original cfcbeb50 was PARTIAL (audit at line ~2746) — only fixed hub→local (`onData()`); local→hub (`sendDataFrame()`/`sendFrame()`) still ignored `send()`'s return (fire-and-forget), and `onLocalData()` was still `do…while` (empty DATA frame on zero-length read). Fixed f69ae5bd: `sendDataFrame()` now pauses the channel's local connection on tunnel-buffer-full and resumes via a new idempotent `armTunnelDrainResume()` (tracks paused channels in `$pausedForTunnelDrain` since the shared tunnel exposes only ONE `onBufferDrain` slot — a naive per-call registration would clobber earlier channels); `sendFrame()` now logs on a dropped tunnel-scoped frame; `onLocalData()` is now a `while` loop that also stops chunking on first backpressure. 3 new tests (zero-length no-frame, single-channel pause/resume, multi-channel resume-on-one-drain); `FakeRelayConnection` test double extended with controllable `send()` + real pauseRecv/resumeRecv counters (default preserves all existing tests). Full Unit 5099/0/11-skip, phpstan/phpcs clean (0 new). **DONE** — see Implementer entry below for detail. - [x] SV-2.4 stream large binary via withFile() ✅ (commit 320efdbc) - [x] SV-2.5 image/photo caching validators + security headers ✅ (commit 3cf0ac4c) - [x] SV-2.6 WS routing indexes + broadcast backpressure ✅ (commit e4270321) - [x] SV-2.7 per-request auth status cache ✅ RE-COMPLETED 2026-07-13: original 786b80fd was PARTIAL (audit at line ~2747) — the 5s-TTL cache was genuinely consulted (primary AC met) but `invalidateUserStatusCache()` had zero callers (revocation TTL-only) and the cache was unbounded. Fixed ba255054: wired invalidation into `AdminUserController`'s approve/disable/reject/delete (the only production path that mutates `users.status`/deletes a user) + DI-bound the nullable ctor param in `AdminServicesProvider` (another instance of the PHP-DI-skips-optional-params landmine) + a container-level regression test; bounded `userStatusCache` with an LRU cap (`USER_STATUS_CACHE_MAX = 5000`) modeled on `ItemRepository::$genreFacetCache`'s insertion-order-LRU pattern. Added cache-hit/TTL-expiry/revocation-within-TTL/LRU-eviction tests + invalidation-wiring tests. Full Unit 5127/0/5-skip, phpstan/phpcs clean. **DONE** — see Implementer entry below for detail. - [x] SV-2.8 list-query projection + materialized filter columns ✅ (commit ef156b1e) - [x] SV-2.9 defer similarity computation to background job ✅ (commit c9ea405d) - [x] SV-3.1 DVR recording data plane ✅ (commit 0579ef07) - [x] SV-3.2 book reader + audiobook player backends ✅ (commit 4f51206f) - [x] SV-3.3 client capability negotiation + loudness normalization ✅ (commit c9e5e599) - [x] SV-3.4 local artwork cache with sized variants ✅ RE-COMPLETED 2026-07-13 (perf-7): original 1b09f897 was INERT (DI landmine, poster_srcset pointed at TMDB CDN). Full 7-sub-step rebuild: sub-1 e2abc09e (non-blocking download) → sub-2+3 ac96e287 (kill DI landmine + config-drive storage dir) → [review NO FINDINGS, fix 18b9b659 include-path-depth, re-review NO FINDINGS] → sub-4 3f6c3cc1 (304 conditional caching) → [review NO FINDINGS] → sub-6 4b7ffd2/fee166c5 (phlix-contracts poster_srcset doc/fixture) → sub-7 79bb46e1 (dedicated route test, 100% coverage) → cumulative integration review (2 LOW findings: invalid 0w srcset descriptor for `original`, non-atomic variant writes) → fix c786bc79 → re-review NO FINDINGS. **DONE.** Docs cycle still owed via the batched server DOCS sweep (cross-cutting, not yet run). - [x] SV-3.5 metadata pipeline: concurrency, 429 backoff, bounded cache ✅ (commit fa4d400f) - [x] SV-3.6 build out Trakt history sync ✅ RE-COMPLETED 2026-07-13 (perf-10): opencode's `cd3be89f` was PARTIAL/prod-inert (pull never invoked; single-page; force-100%; blocking HTTP). Full decompose→review→fix→test cycle this pass: 3.6b `51e6a16e` (de-block HTTP: async client + `\Co\sleep`, transport matches repo pattern) → 3.6a `c7a0094c` (worker-0-gated periodic pull Timer in start.php, NOT index.php; `DEFAULT_PROFILE_ID`) → 3.6c `d7ca10c1` (resume positions via new `getPlaybackProgress()`/`/sync/playback`; `traktSupersedes()` last-write-wins + never-downgrade-completed + no-known-duration skip) → 3.6d `21b04510` (paginate watched history: `X-Pagination-Page-Count` + `\Co\sleep` backoff + `MAX_HISTORY_PAGES=200` cap; `getWithHeaders()`) → CUMULATIVE review (1 HIGH AC-blocking + 3) → fix `23fbc4c5` (**HIGH: client sent NO mandatory `trakt-api-key`/`trakt-api-version:2` headers → every call 403 → sync inert against live Trakt; added shared `apiHeaders()` routing all 4 data-API methods, /oauth excluded** + duration COALESCE null + arm/tick gate alignment) → re-review NO FINDINGS → 3.6e tests `ce962b9e` (Trakt suite 64→105, TraktHistorySync 97.9% / TraktApi 95.4% coverage, incl. outgoing-header regression guard). phpstan L9 + phpcs clean throughout; full Unit baseline 5240/0 at pass start. **DONE** (docs → batched server DOCS sweep). Pre-existing gaps noted, NOT actioned (out of scope): `PluginLoader::bootstrapEnabled()` never called in prod boot (enabled plugins not re-attached after restart — affects push scrobbling too); Trakt token refresh not persisted; latent minutes-as-seconds bug in `extractDurationTicks()` (dormant, watched-history path only). - [x] SV-4.1 segment-cap reservation before glob() ✅ (commit 9f06522b) - [x] SV-4.2 detached-ffmpeg cancellation + apply transcode_timeout ✅ (commit 410ffce0) - [x] SV-4.3 ComskipRunner non-blocking pipe + reachable timeout ✅ (commit 410ffce0) - [x] SV-4.4 WebhookDispatcher backoff + connect-timeout ✅ RE-COMPLETED 2026-07-13: the `410ffce0` reference above is stale/nonexistent audit-trail (that commit does not exist in this repo's history — same rot pattern as the SV-4.10/SV-0.8 stale-hash incidents). Fresh audit found genuinely PARTIAL: `WebhookDispatcher::dispatchAsync`'s jittered-backoff+one-shot-timer was correct but had ZERO callers (dead); `WebhookHttpClient` had no connect-timeout at all; the live admin "test webhook" path (`WebhookDispatcher::sendToWebhook`, S-F10's literal original target) duplicated a fresh blocking cURL call with immediate (zero-delay) retries; the REAL production event-driven delivery path (`WebhookService`/`WebhookEventSubscriber`) already had DB-persisted retry + a genuinely one-shot Timer, but its fixed 30s/300s/1800s schedule had NO jitter at all (a real thundering-herd risk). Fixed `7f434d03`: connect-timeout added to `WebhookHttpClient` (curl + async client, both config-driven); `sendToWebhook` now delegates through a new `postWithHeaders()` (same wire format, no breaking change to registered webhook receivers) + jittered backoff between sync retry attempts; `WebhookDeliveryRecord` gained a jittered `calculateNextRetryDelaySeconds()` (+/-20%) used by `WebhookService::handleFailedDelivery` for BOTH the persisted `next_retry_at` and the retry Timer (single source of truth, can't drift). Dead `dispatchAsync` left in place per §0.1 (not deleted) — flagged below as a candidate for the §6 removal-confirmation queue, not actioned without user sign-off. New tests directly inspect Workerman's own internal timer bookkeeping (not just source review) to prove the retry timer is genuinely one-shot. 82/82 Webhook-filtered tests + full Unit 5152/5152 (8 skip) green, phpstan/phpcs clean. See Implementer entry below for full detail. **DONE.** - [x] SV-4.5 Roku/MusicBrainz blocking-I/O → coroutine/async ✅ (commit 410ffce0) - [x] SV-4.6 original copy variant handling ✅ (commit 088bb99c) - [x] SV-4.7 WS auth enforcement ✅ (commit fecd0ab5; reviewed NO FINDINGS; on-box verified on :8097 — token-less rejected / valid JWT accepted) - [x] SV-4.8 Router static-path fast map + DI for string handlers ✅ (commit c8f94c04) - [x] SV-4.9 Migration ledger + document rewrite-class migrations ✅ (commit c8f94c04) - [x] SV-4.10 Provider-priority config single source of truth ✅ RE-COMPLETED 2026-07-13 — the `c8f94c04` reference above is stale audit-trail from the original opencode pass (that commit does not touch any SV-4.10 file); the 2026-07-12 Claude Code re-audit at line ~2575 below correctly found the provider-priority half NOT-DONE (hrtime half was genuinely done). Real fix: see the "Implementer — SV-4.10" entry near the end of this file for the actual commit hash + full verification. - [x] SV-4.11 Fix PluginCatalogService blocking curl + wrong docblock ✅ (commit c8f94c04) - [x] SV-4.12 Extend stale-job reaper glob to {chunk-*.m4s,seg-*.ts} ✅ (commit c8f94c04) - [x] SV-4.13 Remove superseded whole-file command builders ✅ FINISHED 2026-07-13 (perf-10): the earlier `c8f94c04` removed the older whole-file builders but left `buildTranscodeCommandWithProfile` (zero-caller) behind. This pass: pre-audit re-confirmed ZERO callers (incl. string/reflection refs) → removed the 60-line method + 2 orphaned imports (`HwaccelCommandBuilder`, `HwaccelEncoderProfileInterface`) + fixed the breaking `@see` in `FfmpegRunnerSubtitleBurnInTest` and 3 stale "whole-file path" prose docrefs (`FfmpegRunner` ~:1644/:2034, `HwaccelProfileFactory`). Left `SoftwareProfile.php:21` (live `buildCmafCommand` ref) + `TranscodeManager.php:2006` alone (perf-9's refs there were stale). Commit `4a04e2cc`; review NO FINDINGS; phpstan L9 clean, phpcs 0 err, 343 Transcoding tests green (live per-segment burn-in path intact). **DONE** (docs → batched sweep). ⚠️ §6 REMOVAL-QUEUE CANDIDATE surfaced (NEEDS USER SIGN-OFF, not actioned): `HwaccelCommandBuilder` + `HwaccelProfileFactory::createCommandBuilder()` are now TRANSITIVELY dead (only their own unit tests remain) — §6/R1 scoped this class must-not-alter, so left in place per §0.1. - [x] SV-4.14 Fix phantom self::transcode() docref ✅ (commit c8f94c04) - [ ] SV-4.15 port hub's per-surface rate-limiting framework to server's unprotected auth surfaces — QUEUED 2026-07-13 (perf-7, cross-repo consistency gap). Server only rate-limits `login` (DB-backed, DbLoginRateLimitStore); `register`/`refresh`/WebAuthn start+finish/public JWKS/WS-connect (:8097) have NO rate limiting, unlike hub's general `Common/RateLimit/` framework. Full spec in `/home/sites/phlix/performance_plan.md` §2 S-W4 SV-4.15. **⚠️ GATED (user direction 2026-07-13): do NOT start until hub's rate-limiting work is FULLY finished + reviewed + docs'd** — HB-4.6 Option B (DbRateLimiter + LOGIN repoint) was still in progress when this was drafted; re-audit the hub donor code fresh once it's settled (don't trust this spec's description of hub's shape as final). Also gated behind the rest of the server COMPLETE queue per the plan's existing ordering. - **SV-4.15(a) DONE 2026-07-18** — ported hub's DB-agnostic rate-limit CORE (in-memory only, NO DB, NO wiring): `src/Common/RateLimit/{RateLimiterInterface,RateLimitState,RateLimiter}.php` under namespace `Phlix\Common\RateLimit` (adapted from hub's `Phlix\Hub\Common\RateLimit`; dropped hub-only `@see \Phlix\Hub\Auth\AuthManager`/"finding B1"/"Feature #6" cross-refs). Tests ported: `tests/Unit/Common/RateLimit/{RateLimiterTest,RateLimitStateTest}.php` (14 tests: bucket restart on new/expired window, cap/eviction, `limited = count >= max`, injected-clock determinism, `retryAfter` floor-at-0). Full Unit **5796 / 42183 assertions / 0 fail / 0 err / 8 skip** (baseline 5782 + 14 new; skips are env-dependent). phpstan L9 clean, phpcs 0/0 on new src. **Sub-steps b–h PENDING** (b=?, d=RateLimitProfiles, e=DbRateLimiter+positional-`?` rewrite+migration, + per-surface wiring: register/refresh/WebAuthn/JWKS/WS-connect). - **SV-4.15(b)+(c) DONE 2026-07-18** — (b) added `RateLimitException::retryAfterSeconds(?int $now=null): int<0,max>` (`src/Auth/RateLimitException.php`), delegating `max(0,resetAt-now)` to the ported `RateLimitState::retryAfter()` (mirrors hub). (c) central `RateLimitException`→429 mapping at BOTH dispatch entrypoints via a NEW shared static helper `Application::rateLimitResponse()` (`src/Server/Core/Application.php`) = 429 + `Retry-After: ` + JSON `{error:"Too Many Requests",code:"rate_limited"}`: Workerman `HttpHandler.__invoke` catches `RateLimitException` immediately before the generic `catch(Throwable)`; `Application::handleException()` (the `run()` CGI path) short-circuits it; `public/index.php` registers a `set_exception_handler` that maps it (re-throws all others → status quo). **This fixes the latent login-500 bug** — the existing `DbLoginRateLimitStore`→`AuthManager` trip was uncaught by `AuthController::login` and 500'd with no Retry-After; now 429.

Config: new `rate_limit` block in `config/server.php` — iterates `RateLimitProfiles::defaults()` and reads bare-`getenv()` overrides `RATE_LIMIT__MAX` / `_WINDOW` (server convention, mirrors hls block's HLS_* knobs), falling back to `defaults()`. DI: registered in **`AuthServicesProvider`** (server has NO `CommonServicesProvider`; this is where `DbLoginRateLimitStore`/`AuthManager` are wired) via new private `registerRateLimiters()` — one explicit `factory()` per profile id (NOT autowiring): DB-backed → `new DbRateLimiter($db,$window,$max)` (Connection resolved via `Connection::class`, the SAME pooled `mysql` conn `DbLoginRateLimitStore` uses — readily injectable since a `factory(fn(Connection $db)=>…)` param autowires from the container binding in CoreServicesProvider; NOT a dedicated txn conn), in-memory → `new RateLimiter($window,$max)`; `$window`/`$max` from the `rate_limit` config block per profile.

Pattern per surface: `hit($key)`; if `$state->limited` throw `RateLimitException($state->resetAt, $state->remaining)` BEFORE the real work → central 429 mapping (sub-step c). Keys use `Request::getClientIp()` (X-Forwarded-For aware) NOT the stale `$_SERVER`/`AuthManager::getClientIp()`. **`AuthController`** (`src/Server/Http/Controllers/AuthController.php`): ctor gains 2 OPTIONAL `?RateLimiterInterface` params (`registerLimiter`,`refreshLimiter`, default null → private `enforceRateLimit()` no-op) so the ~20 existing `new AuthController($authManager)` test sites + the degraded no-container `Application::getAuthController()` fallback keep working; `register()` keyed `register:`, `refresh()` keyed `refresh:`. **`WebAuthnController`** (`src/Server/Http/Controllers/WebAuthnController.php`): ctor gains 2 optional `?RateLimiterInterface` params (`startAuthLimiter`,`finishAuthLimiter`); both ceremonies key on the SUBMITTED USERNAME (available in the request body at both limit points — `webauthn_start:` / `webauthn_finish:`), falling back to `` via `limitIdentifier()` only when username absent/blank (start's IP-fallback also covers the missing-field 400 path). **DI** (`src/Common/Container/Providers/AuthServicesProvider.php`): the optional params are bound EXPLICITLY (PHP-DI optional-param landmine — an unbound optional stays null) — `AuthController::class` now registered `autowire()->constructorParameter('registerLimiter', get(RateLimitProfiles::REGISTER))->constructorParameter('refreshLimiter', get(REFRESH))` (was pure-autowire), and `WebAuthnController::class` autowire gains `startAuthLimiter`→`get(WEBAUTHN_START)` / `finishAuthLimiter`→`get(WEBAUTHN_FINISH)`; all 4 resolve to the shared DB-backed `DbRateLimiter` per sub-step d/e.

In-memory/per-worker is deliberate (public, cache-frontable DoS surface). DI: `HubServicesProvider` binds `limiter`→`get(RateLimitProfiles::JWKS)` EXPLICITLY (PHP-DI optional-param landmine); the JWKS profile is registered in `AuthServicesProvider` (providers merge into one container). (h) WS-connect: `WebSocketServer` (`src/Server/WebSocket/WebSocketServer.php`) gains a nullable `wsConnectLimiter` field + `setWsConnectLimiter()` setter (matches the existing `setSyncPlayManager`/`setMetricsCollector` injection style; null = unthrottled so all direct-construction/test sites keep working). At the TOP of `onWebSocketConnect`, AFTER the `findConnection` null-guard but BEFORE the `authMiddleware===null` auth gate, it does `hit('ws_connect:'.$connection->getRemoteIp())`; on `limited` it logs a warning + mirrors the EXISTING reject idiom (`$this->connections->remove($id)` + `$connection->close()`) + `return` — **INLINE, never throws** (a throw out of the hook triggers Workerman `Worker::stopAll()` — verified `vendor/.../Protocols/Websocket.php:440`). **Close code:** plain `close()` (NOT WS 1013) is correct here because the hook fires BEFORE the 101 upgrade response (Websocket.php:440 vs :459), so the socket isn't a WebSocket at the byte layer yet and a raw 1013 close frame would be malformed/out-of-order; a TCP close is the right rejection — spec allows the existing-close fallback. :8097 WS worker is `count=1` so the in-memory limiter is already server-wide (no DB). Injection point: `start.php` WS `onWorkerStart` resolves `RateLimitProfiles::WS_CONNECT` from the per-worker container (best-effort try/catch → unthrottled on failure, never blocks the listener) and calls `setWsConnectLimiter()`.

(The old memory claiming CC subagents can't run npm/vendor-bin/gh is OUTDATED for this runtime.) git identity: Joe Huss . PHP 8.3.6, PCOV coverage driver. Unit suite does NOT need live MySQL (Connection is mocked). Both dual entrypoints exist: `public/index.php` + `start.php` (CLAUDE.md's "start.php doesn't exist" note is STALE — start.php is live, verify by hand, outside CI). **MASTER HEALTH AT PASS START (baseline — master is RED before my changes):** - PHPUnit Unit: 4870 tests, 11 errors, 21 failures, 7 warn, 8 skip, 3 risky. Line coverage 53%. - PHPStan L9 (`-c phpstan.neon.dist`): **6 errors**, incl.: - `FfmpegRunner.php:1168` uses `HwaccelCommandBuilder` — **class.notFound** (class does not exist) - `FfmpegRunner.php:1676` calls undefined `FfmpegRunner::buildHwaccelInputFlags()` - `ItemRepository.php:1283-1284` cast mixed→float / argument.type - PHPCS PSR-12 src/: 1 error + 205 warnings (mostly >120-char lines). - The FfmpegRunner phpstan errors + FfmpegRunnerTest/HlsTest failures are opencode's SV-0.1/SV-1.x hwaccel work left BROKEN (missing/renamed HwaccelCommandBuilder + method). This is IN-SCOPE for SV-0.1 (not pre-existing-unrelated), so fixing it is part of the SV-0.1/SV-0.2 cycle. - ItemRepository failures (testAddStream*) + phpstan cast errors relate to SV-2.8 / stream persistence. **Strategy:** master-red is concentrated in hwaccel (SV-0.1) + ItemRepository (SV-2.8). Drive server W0 in order (SV-0.2 → SV-0.1 first, since we KNOW it's broken), audit-and-complete each. Definition of done requires master green for the touched area (plan §I), so these red items get fixed by their owning step, not waved off. ## Notes / cross-repo blockers - X3 HEAD-over-relay: RESOLVED 2026-07-12 — server ALREADY emits HEAD→END(zero-body)→HTTP_CANCEL for HEAD withFile (RelayConsumer::sendHttpResponse, END unconditional @:1010; headOnly guard @:1002 skips file body). No server change needed; hub HB-0.3 just adds tests. ✅ - X9 heartbeat: RESOLVED 2026-07-12 — server ALREADY sends HEARTBEAT every 30s (RelayConsumer:: startHeartbeatTimer @:1517, repeating timer, RelayConfig::pingInterval default 30) + echoes hub heartbeats (onHeartbeat @:1184). Hub HB-0.1 safe; no server change. ✅ - SV-2.1 pre-audit (via X3 investigation): DONE — sendHttpResponse chunk-streams file-backed GET via streamFileChunks() with MAX_BODY_CHUNK + send-buffer backpressure; empty-body bug fixed; HEAD reports real Content-Length. Confirm with a test when SV-2.1's turn comes. - X10 bug-class sweep: DONE 2026-07-12 — CLEAN. 0 hits for `defined('\Workerman`, `function_exists('Workerman`, `Worker::$_instance` in src/. All class_exists(\Workerman\Timer::class) sites correct. No HTTP-client usleep spin-waits remain (survivors are legit poll/backoff in LiveTv/Roku/NatPmp/pool/transcode; MetadataHttpClient:199 is an SV-3.5 retry-backoff blocking-sleep = adjacent debt, not SV-0.4). Bug-class eradicated. ✅ ## Implementer — SV-0.1 / SV-0.2 complete (2026-07-12) Completed the SV-0.1 gap list + added the missing SV-0.1/SV-0.2 tests. NOT marked done — Review pending. **Code (files touched):** - `src/Media/Transcoding/FfmpegRunner.php` — Fix A: added `use Phlix\Media\Transcoding\Hwaccel\HwaccelCommandBuilder;` (clears phpstan class.notFound @:1168, which was the `new HwaccelCommandBuilder(...)` in `buildTranscodeCommandWithProfile`). Fix B: implemented `private function buildHwaccelInputFlags(HwaccelCapability): string` (clears method.notFound @:1676; unbreaks the live `buildHwaccelSegmentCommand` path). Per-vendor input/decode flags placed before `-i`, deriving device from `$capability->extra_args` (mirrors the vendor profiles' `getInputDeviceArgs()` used by HwaccelCommandBuilder so the two paths don't diverge): vaapi → `-hwaccel vaapi -hwaccel_device -hwaccel_output_format vaapi`, qsv → `-hwaccel qsv -qsv_device `, nvenc/cuda → `-hwaccel cuda [-hwaccel_device N] -hwaccel_output_format cuda`, videotoolbox/amf mapped, software/unknown → ''. Also added `getHardwareAccelerationSummary(): array` for the boot log. (Idempotent probe guard `$hwaccelProbed` already existed.) - `start.php` — Fix C: added `use ...LogChannels`; in the HTTP worker `onWorkerStart`, resolve the FfmpegRunner, call `probeHardwareAcceleration()` explicitly at worker start (idempotent), and log the chosen accelerator ONCE via `LoggerFactory::get(LogChannels::STREAMING)` + `getHardwareAccelerationSummary()`. Runs outside any coroutine so the probe's blocking exec can't stall the loop. DI `setConfig` + factory probe retained (lazy once-probe still covers the FPM `public/index.php`). - `src/Server/Core/Application.php` — Fix D: `setConfig(\Phlix\Config\HwAccelConfig::get())` after both non-segment `new FfmpegRunner(...)` (MediaItemController→GaplessPlaybackManager ~:2760, SubtitleController ~:2790) so every runner shares the single merged config source. **Tests (added, build-out opencode skipped):** - `tests/Unit/Config/HwAccelConfigTest.php` (7 tests) — SV-0.2 regression: single merged config; `enabled` from hwaccel_base.php; tone_mapping_mode/preferred_accelerator from transcoding.php; ffmpeg.php `hwaccel` === HwAccelConfig::get() (no contradictory flags); hwaccel.php shares base; cached. - `tests/Unit/Media/Transcoding/FfmpegRunnerHwaccelTest.php` (5 tests) — segment cmd contains `-hwaccel` + `-c:v h264_nvenc` when registry (reflection-seeded, deterministic) reports HW; vaapi input flags; null when no HW encoder; software fallback `buildSegmentCommand` uses libx264; summary reflects probe. - `tests/Unit/Common/Container/Providers/TranscodeServicesProviderTest.php` (2 tests) — resolving FfmpegRunner through the provider calls setConfig (config has merged `enabled`) + probe (registry set, summary reflects seeded encoder). **Verification:** - phpstan L9 `-c phpstan.neon.dist`: the TWO hwaccel errors (:1168 class.notFound, :1676 method.notFound) are GONE. Remaining: 3 pre-existing errors NOT mine — ItemRepository.php:1283-1284 (SV-2.8) + WebPortalServicesProvider.php:295 (SV-3.2/BookController). - phpunit: new tests 13/13 green; `--filter Hwaccel` 135/135 green. - phpcs PSR-12 on touched src (FfmpegRunner.php, Application.php): 0 errors (only pre-existing >120-char warnings on untouched lines). start.php clean. (Test method snake_case matches existing test convention; tests/ is outside the `src/`-only phpcs scope.) - Pre-existing FfmpegRunnerTest `buildTranscodeCommand()` drift STILL FAILS (3 errors) — SV-4.13's job, left untouched as instructed. ## Reviewer (per-step: SV-0.1 + SV-0.2) — 2026-07-12 Verified: phpstan L9 clean on all touched files (only the 3 pre-existing errors remain — ItemRepository.php:1283-1284 + WebPortalServicesProvider/BookLibraryManager argument.type — NOT introduced here). `--filter Hwaccel` 135/135 green; the 13 new tests green. SV-0.2 is fully correct (single source `HwAccelConfig::get()`; ffmpeg.php + hwaccel.php both delegate; no contradictory `enabled`; `HwAccelConfigTest` genuinely asserts ffmpeg.php['hwaccel'] === HwAccelConfig::get() and enabled/tone-map/preferred provenance). Fix C probe placement is correct (lazy shared DI factory + explicit idempotent `probeHardwareAcceleration()` in `start.php` onWorkerStart, OUTSIDE any coroutine, before the loop serves — blocking exec at boot does not violate the no-native-exec hook mask). Fix D config source is correct with no side effects. Findings: 1. **[CONFIRMED — correctness, GPU-only so untestable on this box]** `src/Media/Transcoding/FfmpegRunner.php:1819-1867` (`buildHwaccelInputFlags`, nvenc + vaapi cases) vs `:1746-1760` (`buildHwaccelSegmentCommand` filter chain). The nvenc case emits `-hwaccel_output_format cuda` and the vaapi case emits `-hwaccel_output_format vaapi`, which force the decoded frames to stay as HARDWARE surfaces (CUDA / VAAPI). But `buildHwaccelSegmentCommand` then appends SOFTWARE filters to the same command: `scale={w}:{h}:...` whenever width+height are supplied (line 1756 — i.e. every downscaled ABR variant) and the software tone-map graph whenever `$needsToneMap` is true (lines 1746-1750, i.e. all HDR content on non-HDR-capable encoders — which includes `h264_nvenc`/`h264_vaapi`). ffmpeg does NOT auto-insert `hwdownload` between a hardware-format source and a software filter; it aborts with "Impossible to convert between the formats". Net effect: on a real NVENC/VAAPI box the HW segment encode SUCCEEDS only for the full-resolution, non-HDR "original" variant and FAILS for every downscaled variant and every HDR-tone-mapped segment — directly undermining the SV-0.1 AC ("a segment encodes via the HW encoder … falls back to libx264 cleanly"; here it would hard-fail, not fall back). Note the NVENC profile (`NvencProfile::getInputDeviceArgs`) deliberately emits only `-hwaccel cuda -hwaccel_device N` with NO `-hwaccel_output_format`, precisely so decoded frames land in system memory and software filters work; the segment path should do the same. Fix direction: drop `-hwaccel_output_format cuda`/`vaapi` (let frames download to system memory so the existing software scale/tonemap filters apply), OR switch the segment filter chain to hardware filters (`scale_cuda`/`scale_vaapi`) with `hwdownload,format=...` before any software tone-map. 2. **[MAINTAINABILITY / plan-directive miss]** `src/Media/Transcoding/FfmpegRunner.php:1819-1867`. The plan (performance_plan.md SV-0.1) and the review brief both call for aligning with `HwaccelCommandBuilder`'s vendor logic "rather than diverging". `buildHwaccelInputFlags` reimplements the input-device flags independently of the vendor profiles' `getInputDeviceArgs()`, and the two genuinely diverge: vaapi profile → `-vaapi_device ` vs. segment → `-hwaccel vaapi -hwaccel_device -hwaccel_output_format vaapi`; nvenc profile has no output-format vs. segment adds one. The method docblock's claim that it "mirrors the vendor profiles' getInputDeviceArgs()" is therefore inaccurate. Two hand-maintained codepaths for the same concept will drift. Fix direction: delegate to `HwaccelProfileFactory->…->getInputDeviceArgs($capability)` (already imported) so the segment and whole-file paths share one source of truth — this also resolves finding #1 for free. 3. **[TEST COVERAGE GAP at the exact risky seam]** `tests/Unit/Media/Transcoding/FfmpegRunnerHwaccelTest.php:74-128`. Both HW-path tests call `buildHwaccelSegmentCommand` with `['video_codec' => 'libx264']` only — no `width`/`height` and no `require_hdr_tone_map` — so the scale/tone-map filter branch (the branch that collides with `-hwaccel_output_format` per finding #1) is never exercised. The vaapi test even asserts `-hwaccel_output_format vaapi` is present, baking the questionable flag in as expected. The tests pass trivially and cannot catch #1. Fix direction: add a case with width/height (and one with `require_hdr_tone_map => true`) asserting the input flags and the filter chain are format-compatible (i.e. no software `scale=`/tonemap after a hardware-only output format). 4. **[LOW — dual-entrypoint / observation]** `public/index.php` (bootstrap) was not touched. The plan's SV-0.1 step asks to "mirror the DI change in start.php and index.php bootstraps". Functionally index.php IS covered (it builds the container via `ContainerFactory::create`, and the shared `TranscodeServicesProvider` factory runs `setConfig()` + `probeHardwareAcceleration()` lazily on first `FfmpegRunner` resolution), so this is acceptable under the resident model — but that entrypoint emits no one-time boot log of the chosen accelerator and probes lazily on first transcode rather than at worker start. Confirm this is intended; if a boot-time log is wanted for the index.php entrypoint it must be added there too. Out-of-scope note (NOT introduced by this diff, do not fix here): `QsvProbe.php:67` stores the device under key `'-device'` while both `QsvProfile::getInputDeviceArgs` and the new `buildHwaccelInputFlags` read `extra_args['device']`, so QSV always uses the `/dev/dri/renderD128` default. Harmless today; flagging for a future Hwaccel-probe build-out step. ## Fixer — SV-0.1 REVIEW-1 findings (2026-07-12) Fixed ALL REVIEW-1 findings (#1/#2 correctness defect, #3 test gap, #4 confirmed, plus the QSV device-key bug). phpstan/phpunit/phpcs green; only the 3 pre-existing phpstan errors remain. **#1 + #2 (CONFIRMED correctness defect — root fix via profile delegation).** `src/Media/Transcoding/FfmpegRunner.php` - Reworked `buildHwaccelInputFlags(HwaccelCapability)` to STOP re-deriving per-vendor input flags (which emitted `-hwaccel_output_format cuda`/`vaapi`, keeping decoded frames on a HW surface that the software `scale=`/tonemap filters cannot consume → ffmpeg "Impossible to convert between the formats" on every downscaled/HDR NVENC/VAAPI segment). It now DELEGATES to the resolved vendor profile's `getInputDeviceArgs($capability)` — the SAME source of truth `HwaccelCommandBuilder` uses for the whole-file path (:422). Added `HwaccelProfileFactory::getProfileForVendor(string): ?profile` (direct vendor→profile lookup, no availability fallback) and a lazily-built `$hwaccelProfileFactory` field on the runner. NONE of the profiles emit `-hwaccel_output_format`, so decoded frames now land in SYSTEM MEMORY where the software scale/tonemap filters are valid. Rewrote the (previously inaccurate) docblock to describe the delegation. - Frames-flow now: HW/SW decode → frames in system memory → software scale/tonemap (valid) → for VAAPI/QSV encoders (which cannot consume system-memory frames) a trailing `format=nv12,hwupload` (`…extra_hw_frames=64` for QSV) is appended AFTER the software filters via the new `hwaccelUploadFilter(vendor)` helper → HW encode. NVENC/VideoToolbox/AMF accept system-memory frames so no upload filter is added. This makes BOTH the downscaled and the HDR-tonemap segment commands coherent for NVENC/VAAPI/QSV; the libx264 software fallback path (`buildSegmentCommand`) is unchanged. - Note (delegation consequence, documented not fixed): v4l2 now also delegates to `V4L2Profile` (capture-oriented `getInputDeviceArgs`) exactly as the whole-file `HwaccelCommandBuilder` already does — segment and whole-file paths are now identical for every vendor, which is the point of #2. Any V4L2Profile transcode-vs-capture concern is a single, shared profile issue (out of scope here). **#3 (test gap that hid #1).** `tests/Unit/Media/Transcoding/FfmpegRunnerHwaccelTest.php` - Corrected the vaapi test: it no longer asserts `-hwaccel_output_format vaapi` (the buggy expectation) — now asserts `-vaapi_device` + `-c:v h264_vaapi` and NO `-hwaccel_output_format`. - Added 4 coherence cases exercising the previously-untested colliding branch: `test_downscaled_nvenc_segment_has_no_hw_surface_software_filter_collision` (width/height → software `scale=1280:720`, no output-format), `test_downscaled_vaapi_segment_uploads_after_software_scale` (scale + `hwupload` ordered AFTER the scale, no output-format), `test_hdr_tonemap_nvenc_segment_has_no_hw_surface_collision` (forces a real tonemap graph via an anon FfmpegRunner subclass + an HDR-capable NVENC cap; asserts tonemap present, no output-format), and `test_qsv_segment_uses_probe_device` (non-default QSV device flows through to `-qsv_device /dev/dri/renderD129`, hwupload present, no output-format). **QSV device-key bug (in-domain).** `src/Media/Transcoding/Hwaccel/VendorProbe/QsvProbe.php:67` - Fixed the writer: `extra_args` key `'-device'` → `'device'` so it matches what `QsvProfile::getInputDeviceArgs` (and the delegated segment path) read. QSV now honors the probed device instead of always falling back to `/dev/dri/renderD128`. Reader-side already had a test (`QsvProfileTest::test_qsv_device_arg`); added the whole-chain `test_qsv_segment_uses_probe_device`. **#4 (low — confirmed, no code change).** `public/index.php` is intentionally NOT probed at boot: it builds the container via `ContainerFactory::create`, and the shared `TranscodeServicesProvider` factory runs `setConfig()` + `probeHardwareAcceleration()` LAZILY on first `FfmpegRunner` resolution (once, via the guard) — correct for the resident model. The one-time boot-log of the chosen accelerator is a `start.php`/daemon concern only (that entrypoint probes explicitly in `onWorkerStart` and logs); the FPM/index.php path probes lazily on first transcode and does not emit a boot log. Accepted as intended. **Verification (this fixer pass):** - phpstan L9 `-c phpstan.neon.dist`: only the 3 PRE-EXISTING errors remain (ItemRepository.php:1283-1284 cast.double; WebPortalServicesProvider.php:295 BookLibraryManager argument.type). NONE introduced. - phpunit `--filter Hwaccel`: 139 tests / 333 assertions green (incl. the 4 new coherence cases). Related suites (HwaccelProfileFactoryTest, QsvProfileTest, TranscodeServicesProviderTest, the full FfmpegRunnerHwaccelTest): 28/28 green. - phpcs PSR-12 on FfmpegRunner.php + QsvProbe.php + HwaccelProfileFactory.php: 0 errors (only pre-existing >120-char warnings on untouched lines 756 / 71 / 82). **Extra (user-requested during this pass): cleared the pre-existing phpstan L9 + phpcs errors.** Master phpstan L9 is now fully **[OK] No errors** (was 3) and phpcs PSR-12 on `src/` has **0 errors** (was 1); the ~205 line-length WARNINGS are left as-is (plan §0.2 marks them non-blocking). - `src/Media/Library/ItemRepository.php:1283-1284` (SV-2.8 leftover) — `cast.double` (Cannot cast mixed to float) on `(float) $streamData['max_luminance'|'avg_luminance']`. Guarded with `is_numeric($streamData[...] ?? null)` (behaviour-neutral for numeric/absent; a non-numeric string now yields null instead of `0.0`, a minor correctness win). The pre-existing `testAddStream*` red is SV-2.8 test-drift (fails identically without this edit — verified via git stash), NOT caused here. - `src/Common/Container/Providers/WebPortalServicesProvider.php:295` (SV-3.2 leftover) — `argument.type`: the BookController factory resolved `BookLibraryManager` where the ctor needs `LibraryManager`. BookController calls `getAllLibraries()`/`getLibrary()` which BookLibraryManager does NOT expose, so this was also a latent runtime fatal — switched the factory to `$c->get(LibraryManager::class)` (already registered/autowired + used by sibling factories in the same provider) and dropped the now-unused import. - `src/Server/Http/Controllers/AudiobookController.php:40` — phpcs PSR-12 "Opening brace must not be followed by a blank line": removed the stray blank line after the class brace. ## Reviewer (RE-REVIEW / REVIEW-2, SV-0.1 FIX-1) — 2026-07-12 Re-reviewed the fix diff `0a35848a..4d49d9bc`. The REVIEW-1 CONFIRMED defect (HW-surface frames colliding with software scale=/tonemap) is genuinely fixed and the fix is correct for NVENC / VAAPI / VideoToolbox / AMF. Verified locally: phpstan L9 `-c phpstan.neon.dist` = [OK] 0 errors; phpunit `--filter Hwaccel` = 139 tests / 333 assertions green. What I confirmed CORRECT (no action): - Delegation: `buildHwaccelInputFlags()` now returns `profile->getInputDeviceArgs($cap)` (same source of truth as `HwaccelCommandBuilder`) and no profile emits `-hwaccel_output_format`, so decoded frames land in system memory where the software scale=/tonemap filters are valid. `getProfileForVendor()` does a direct `$this->profiles[strtolower($vendor)] ?? null` lookup — unknown/software vendor → null → '' (no crash, no input flags), and `hwaccelUploadFilter()` default '' → no stray upload. Safe. - Filter ORDER (FfmpegRunner.php:1746-1773): tonemap → scale → hwupload, emitted in that array order; hwupload appended even with no other filter (needed for the full-res VAAPI/QSV "original" variant). - NVENC / VideoToolbox / AMF: no upload filter (encoders consume system-memory frames; nvenc uploads internally). No residual `-hwaccel_output_format cuda`. Correct. - VAAPI: `-vaapi_device ` + `format=nv12,hwupload` + `-c:v h264_vaapi` is the canonical software-decode→hardware-encode pattern; `-vaapi_device` gives hwupload its device. CORRECT. - 10-bit/HDR: the tonemap graph ends in `format=yuv420p`; a following `format=nv12` (8-bit 4:2:0 → 8-bit 4:2:0) before hwupload is a safe no-loss conversion, not a clobber. Safe. - libx264 no-HW fallback (`buildSegmentCommand`) unchanged. - Tests genuinely guard the seam: `_downscaled_vaapi_segment_uploads_after_software_scale` asserts `strpos(scale) < strpos(hwupload)` (ordering), the NVENC downscale/HDR cases assert scale/tonemap present with NO `-hwaccel_output_format`, and `_qsv_segment_uses_probe_device` asserts the probed device reaches `-qsv_device`. A reorder or a dropped upload would fail these. Good. - Scope-creep edits verified CORRECT: `WebPortalServicesProvider.php:295` — BookController's ctor is typed `LibraryManager` and it calls `getAllLibraries()`/`getLibrary()` then filters `type==='book'` itself (BookController.php:126-127,159), so it needs the generic manager, not a book-scoped one; the old `BookLibraryManager` resolve was a real TypeError-at-construction, fix is right. `ItemRepository.php:1283-1284` — `is_numeric(... ?? null) ? (float) : null` yields null (not a silent 0.0) for non-numeric/absent luminance, a sane "unknown", strictly better than the old `isset()` cast. `QsvProbe.php:67` `'-device'`→`'device'` aligns writer with the only reader (`QsvProfile::getInputDeviceArgs`), no other reader of `'-device'` exists. Findings: 1. **[LOWER-CONFIDENCE — GPU-only, Intel-QSV only, unverifiable on this GPU-less box]** `src/Media/Transcoding/FfmpegRunner.php:1861-1868` (`hwaccelUploadFilter`, `qsv` arm) together with `QsvProfile::getInputDeviceArgs` (emits only `-qsv_device `). For QSV the command becomes `... -qsv_device -i in -vf "...,format=nv12,hwupload=extra_hw_frames=64" -c:v h264_qsv ...`. Two ffmpeg-semantics concerns that this box cannot catch: (a) The generic `hwupload` filter needs a *filter* hardware device to upload INTO. `-qsv_device` is an option consumed by the h264_qsv *encoder*, not a filter-device initializer; the documented QSV software→hardware upload pattern initializes the device explicitly (`-init_hw_device qsv=hw:/dev/dri/renderDXXX -filter_hw_device hw`) and neither flag is emitted anywhere in the codebase (grep for `init_hw_device`/`filter_hw_device` = none). On a real Intel box `hwupload` may abort with "A hardware device reference is required to upload frames to." (b) The canonical QSV chain is `hwupload=extra_hw_frames=N,format=qsv` (upload, then declare the QSV pixel format), whereas this emits `format=nv12,hwupload`. VAAPI's `format=nv12,hwupload` is fine because `-vaapi_device` sets the default device; QSV differs and this asymmetry is exactly the "QSV needs a different upload than VAAPI" case flagged in the review brief. The fix did add `extra_hw_frames=64` (good) but likely still lacks the device-init half. Why it matters: SV-0.1 AC requires "on a box with … QSV available … a segment encodes via the HW encoder." VAAPI and NVENC are correct with high confidence; QSV specifically remains unverified and at risk of a hard ffmpeg failure (not a clean libx264 fallback). NOT a regression introduced by this fix — the whole-file `HwaccelCommandBuilder` path has the same/worse QSV limitation (it emits no hwupload at all) — so this can be tracked/verified rather than blocking, but it should be verified on real Intel hardware before QSV is claimed working. Fix direction: for QSV emit `-init_hw_device qsv=hw: -filter_hw_device hw` on the input side (in place of / alongside `-qsv_device`) and use `hwupload=extra_hw_frames=64,format=qsv`; confirm on an Intel box (`ffmpeg -qsv_device …` vs `-init_hw_device qsv`). Applies equally to the whole-file builder for consistency. ## Implementer — 2026-07-12 (SV-0.3 + SV-0.4 combined fix + tests) **Scope:** the 4 async HTTP clients' worker-context detection + coroutine wait. SV-0.5 (WS reaper/heartbeat) NOT touched. **SV-0.4 bug fixed — Channel::pop() only ever reached inside a coroutine (getCid()>0):** Added shared guard `WorkerContext::inCoroutine()` = `extension_loaded('swoole') && Swoole\Coroutine::getCid() > 0`. - `src/Media/Metadata/MetadataHttpClient.php` (get loop): gate now `needsBlocking = !isEventLoopRunning() || !inCoroutine() || requiresBlockingCurl(url)`. getCid>0 (+event loop, +not-TLS) → requestAsync (Channel); getCid<=0 → requestCurl (blocking). TLS still → curl. - `src/Webhooks/WebhookHttpClient.php` (post): `useAsync = isEventLoopRunning() && inCoroutine() && !requiresBlockingCurl(url)` → postAsync (Channel) else postCurl. Timer-dispatched webhooks (non-coroutine) now correctly blocking. - `src/Admin/S3Client.php` (doRequest): same `useAsync` gate → requestAsync (Channel) else requestCurl. - `src/Hub/HttpClient.php` (request): INVERSION corrected. Was: in-coroutine→requestCoroutine (valid) but non-coroutine→requestAsync (Channel, INVALID). Now: requiresBlockingCurl→curl; `isEventLoopRunning() && inCoroutine()`→requestCoroutine (hooked client suspends the coroutine — coroutine-valid, the existing correct in-coroutine path is KEPT); else→requestCurl. Removed the misplaced Channel `requestAsync()` method (now dead) and the unused `use Workerman\Coroutine;` import. EventLoopTls `requiresBlockingCurl()` fallback preserved (blocking-by-design) and still reachable in every client. Timeout→clean-error/null behavior unchanged. **Tests added:** - `tests/Unit/Common/Runtime/WorkerContextTest.php` — SV-0.3: `isEventLoopRunning()` false outside a worker; SV-0.4: `inCoroutine()` false on main stack; branch-selection guard via real client seam (`WebhookHttpClient::post('')` returns blocking-only `'Empty URL'` sentinel → proves blocking path chosen out of coroutine). - `tests/Unit/Common/Runtime/CoroutineChannelWaitTest.php` — SV-0.4 **coroutine strategy** (swoole present on box): `Swoole\Coroutine\run` asserts (a) `inCoroutine()` flips false→true across coroutine boundary; (b) Channel waiter wakes on callback `push(true)` before timeout; (c) returns false after actually waiting the timeout window (clean timeout, not the immediate-false of an out-of-coroutine invalid pop). Drives the Channel/callback pattern directly because the private client methods need a live Workerman\Http\Client + event loop a bare coroutine can't supply; the pattern is byte-for-byte the client callbacks. Deliberately never calls Channel::pop out of a coroutine (that emits a warning = the bug). **Verify:** phpstan (level 9, `-c phpstan.neon.dist`) 0 errors. phpunit `--filter 'WorkerContext|CoroutineChannelWait|HttpClient|MetadataHttpClient|Webhook|S3Client'` = OK (91 tests, 244 assertions). phpcs PSR12 on all 5 src files + 2 tests = 0 errors (only pre-existing >120-char warnings in S3Client lines 212/238/256, not on changed lines). **Adjacent (out of scope, noted):** `src/Plugins/Catalog/PluginCatalogService.php::defaultFetcher()` (SV-4.11) has the same latent no-getCid-gate on its `asyncFetch` Channel path — separate step, not touched here. ## Reviewer (per-step, SV-0.3 + SV-0.4 combined fix) — 2026-07-12 Reviewed diff `ce2d2e04` (fix) + `2a243857` (tests). Verified locally: phpstan L9 `-c phpstan.neon.dist` = [OK] 0 errors; phpunit `--filter 'WorkerContext|CoroutineChannelWait|Webhook|MetadataHttpClient|S3Client|HttpClient'` = OK (91 tests, 244 assertions); CoroutineChannelWaitTest ran (not skipped — swoole loaded). CONFIRMED CORRECT (no action): - Invariant holds in ALL 4 clients — every `Swoole\Coroutine\Channel::pop()` is now reachable only with `getCid()>0`: - MetadataHttpClient:357 (requestAsync) gated by `!needsBlocking` where needsBlocking = `!isEventLoop || !inCoroutine || requiresBlockingCurl`. - WebhookHttpClient:126 (postAsync) gated by `useAsync = isEventLoopRunning && inCoroutine && !requiresBlockingCurl`. - S3Client:390 (requestAsync) gated by the same useAsync. - Hub/HttpClient: no Channel at all after the fix — requestCoroutine() uses the hooked Workerman\Http\Client synchronously (suspends the coroutine), gated on `isEventLoopRunning && inCoroutine`; else blocking cURL. The false-timeout bug path (Channel::pop out of a coroutine) is eliminated. - HttpClient inversion fix: dead `requestAsync()` (Channel) method removed; no residual caller/reference; `use Workerman\Coroutine;` import removed and no remaining `Coroutine::`/`Workerman\Coroutine` usage in the file. requestCoroutine is genuinely coroutine-safe (hooked client, no Channel). - EventLoopTls `requiresBlockingCurl()` fallback stays reachable in all 4 (https- under-Swoole → blocking cURL); the new inCoroutine gate is ANDed alongside it, so TLS is never routed through the coroutine/Channel path. - Timeout behavior: clean error/null preserved (requestCoroutine throws on null; Channel paths translate pop-timeout to null/error). CoroutineChannelWaitTest proves a real timeout waits the window (>=40ms), not the immediate-false of an invalid pop. - `WorkerContext::inCoroutine()` = `extension_loaded('swoole') && Coroutine::getCid()>0` — safe when swoole absent (returns false in CLI/PHPUnit → forces blocking path). - Tests are real, not shallow: CoroutineChannelWaitTest exercises a live `Swoole\Coroutine\run` — inCoroutine() flip false→true, wake-on-push before timeout, and clean-timeout-after-waiting; it deliberately never pops outside a coroutine. WorkerContextTest proves both guards false out-of-worker/out-of-coroutine AND the branch selection via a real client seam (WebhookHttpClient::post('') → blocking-only 'Empty URL' sentinel). Out of scope (correctly NOT reported as an SV-0.4 finding): PluginCatalogService.php:538 has the same ungated Channel::pop latent gap — belongs to SV-4.11. NO FINDINGS --- ## Implementer — 2026-07-12 — SV-0.5 completion (3 audit gaps) The `function_exists`→`class_exists` fix (3 sites), the per-worker repeating WS reapers, and the one-shot stream heartbeats were already in place. This pass closes the three RE-AUDIT gaps. ### Gap 1 — S-F28: application-level WS ping (was ABSENT) - Mechanism chosen: **server-side ping timer + pong callback** (NOT `pingInterval`/`pingNotResponseLimit`). Reason: Workerman 5.x's `Worker` does NOT expose those properties (they lived in GatewayWorker); the WS protocol layer only offers the dynamic `onWebSocketPong` worker callback. Verified in `vendor/workerman/workerman/src/Worker.php` (no pingInterval) and `Protocols/Websocket.php` (reads `$connection->worker->onWebSocketPong`). - `Connection.php`: added `pendingPings` counter + `ping()` (sends a WS PING control frame `"\x89"`, restores the prior frame type, increments the counter), `recordPong()` (reset + refresh activity), `getPendingPings()`. - `WebSocketServer.php`: bind `onWebSocketPong` in the constructor (`@phpstan-ignore property.notFound` — dynamic Workerman callback); arm a ping `Timer::add($pingInterval, …)` in `onStart()` (config `ping_interval` default 30s, `ping_not_response_limit` default 2). `pingConnections(int $limit)` reaps any connection whose `getPendingPings() >= $limit` (close + pool remove), else pings it. `onWebSocketPong()` clears the counter for the ponging connection. - Net: a killed/half-open client stops ponging → after `$limit` unanswered pings (~2× ping window) it is closed and removed. A live client's pong resets the counter each sweep so it is never reaped. ### Gap 2 — key stream heartbeat per-session + teardown on stream end - `StreamSessionService.php`: added `heartbeatTimerIds` map (session id → timer id), `registerHeartbeatTimer($sessionId)` (dedup: no-op if a timer is already pending for the session; one-shot `Timer::add(30, …, [], false)`), `onHeartbeatTimerFired($sessionId)` (clears its own slot so the next request re-arms it, then refreshes the heartbeat), `cancelHeartbeatTimer($sessionId)` (`Timer::del` + unset), and `activeHeartbeatTimerCount()`. `releaseStream()` now calls `cancelHeartbeatTimer()` before the DELETE — the canonical stream-teardown path. - Callers now delegate: `HttpHandler::checkStreamLimit()` and `StreamLimitMiddleware::__invoke()` call `$service->registerHeartbeatTimer()`; their private `registerStreamHeartbeat`/`registerHeartbeat` helpers were removed. StreamSessionService is a PHP-DI shared singleton within the worker, so both paths share one registry (dedup + teardown are consistent). - Result: at most ONE heartbeat timer per active session (was: one one-shot per request — bounded but re-created each HLS segment). Timers self-clear on fire and are cancelled on release. `cleanupStaleStreams()` (bulk SQL DELETE) does not carry session ids, but the one-shot + self-clear design means a stale session's last timer already fired and cleared ~30s after its final request, so no accumulation results from that path. ### Gap 3 — tests - `WebSocketServerTest`: replaced the shallow `testOnStartDoesNotThrow` (stale comment referencing the old `function_exists` early-return) with `testOnStartRegistersReaperAndPingTimers` — asserts `onStart()` arms exactly 3 Workerman timers (conn reaper + group reaper + ping) via reflection on `Timer::$status`. Added `testPingSweepReapsNonRespondingConnection` (peer never pongs → reaped on the sweep that hits the limit) and `testRespondingConnectionIsNeverReaped` (pong each sweep → survives). - New `tests/Unit/Access/StreamSessionServiceTest`: `testHeartbeatTimerIsKeyedDedupedAndSelfClearing` (keyed, dedup no-op, one-shot self-clear, re-arm, teardown), `testTimerFiringRefreshesHeartbeat` (fire → one UPDATE + slot cleared), and the **leak test** `testNoTimerLeakAcrossManyStreamStartStopCycles` — 100 sessions × 3 registers each yields exactly 100 timers (dedup), and after 100 `releaseStream()` calls the active-timer count returns to baseline (0). Deterministic: drives the callbacks directly, no real sleeps. ### Dual-entrypoint No mirroring needed. The WS worker runs only in `start.php` (resident path); `public/index.php` has no WS worker. All ping/reaper wiring lives inside `WebSocketServer` (constructor + `onStart`), which `start.php` already instantiates and calls — so both the constructor binding and the timer arming are captured automatically. ### Verification - `phpstan analyze -c phpstan.neon.dist`: **0 errors**. - `phpunit --filter 'WebSocketServer|StreamLimit|HttpHandler|StreamSession'`: **85 tests, 175 assertions, OK** (incl. the new tests). - `phpcs --standard=PSR12` on touched files: no new errors/warnings (the 5 long-line warnings in StreamSessionService are pre-existing in `getActiveStreamsForProfile`). NO FINDINGS (pending review) ## Reviewer (per-step) — SV-0.5 — 2026-07-12 Reviewed commits `4decf21e`, `dd842326`, `98073f0f` against the SV-0.5 Acceptance Criteria, §0.3 async/Swoole + dual-entrypoint rules, and the ping/heartbeat correctness contract. Verifications (this box): - `phpunit --filter 'WebSocketServer|StreamLimit|HttpHandler|StreamSession'` → **OK (85 tests, 175 assertions)**. - `phpstan analyze -c phpstan.neon.dist` → **[OK] No errors** (645/645). - `phpcs --standard=PSR12` on the 5 touched files → **0 errors**, 5 pre-existing >120-char warnings in `StreamSessionService::getActiveStreamsForProfile` (lines 356-361, untouched by this step; OK per §0.2). What is genuinely correct (high confidence): - `function_exists`→`class_exists` applied at all 3 sites (WebSocketServer.php:124, StreamSessionService.php:165/221, and the removed HttpHandler/StreamLimitMiddleware helpers). Reaper + ping timers now arm. - Stream heartbeat timers are one-shot (`Timer::add(30,…,[],false)`), per-session keyed, deduped, self-clearing on fire, and cancelled in `releaseStream()`. The leak test is deterministic (100 sessions × 3 registers → 100 timers → 0 after release) and genuinely guards the seam. DI confirms one shared PHP-DI singleton feeds both the HttpHandler (`container->get`) and StreamLimitMiddleware (autowired) paths, so the registry is shared as claimed. - The `ping()` frame encoding is valid: `Websocket::encode` uses `$connection->websocketType` as the frame first byte, so `websocketType="\x89"` + `send('')` emits a well-formed empty-payload PING; the prior type is restored synchronously (encode runs inside send()). Pong→recordPong resets the counter, so a responding client is never reaped (test confirms). ### Findings 1. **[HIGH — behavioral AC unverified; static analysis says it fails in the live path] The WS ping/pong callback surface is bound to a Worker that never listens in the resident `start.php` path (dual-entrypoint gap, §0.3).** - `WebSocketServer::__construct` binds `onConnect`/`onMessage`/`onClose`/ `onWebSocketPong` and creates its socket on its **own** `$this->worker` (`WebSocketServer.php:81-97`). But `start.php` does **not** run that worker: it declares a **separate** listener `$wsWorker = new Worker('websocket://0.0.0.0:8097')` at `start.php:239` (the pre-`runAll` registered worker), and inside `$wsWorker->onWorkerStart` it constructs the `WebSocketServer` and calls only `$wsServer->onStart()` (`start.php:274-287`). It never calls `$wsServer->run()` and never copies WebSocketServer's callbacks onto `$wsWorker`. - The `WebSocketServer` internal worker is constructed **after** `Worker::runAll()` (inside a forked child's `onWorkerStart`); Workerman only calls `listen()` during `runAll()` → `initWorkers()` (`vendor/workerman/workerman/src/Worker.php:588-609`, and `start.php:356-357` states this rule outright). So that worker never accepts connections — `$wsWorker` is the real listener. - The Websocket protocol resolves the pong handler as `$connection->onWebSocketPong ?? $connection->worker->onWebSocketPong` (`vendor/workerman/workerman/src/Protocols/Websocket.php:215`), where `$connection->worker` is the **accepting** worker (`$wsWorker`), which has no `onWebSocketPong` (nor `onConnect`/`onMessage`). Consequences in production: the pool is never populated via `WebSocketServer::onConnect`, and even if it were, pongs would not reach `recordPong()` → `pendingPings` never resets. The ping sweep therefore cannot satisfy the AC ("a killed WS client is reaped within the ping window" **and** a live/ponging client survives). - The unit tests pass because they drive `WebSocketServer` in isolation, where its own internal worker holds the callbacks and pool — they cannot catch this integration gap. Per §0.7, a behavioral change like this needs an on-the-box verification against the running :8097 worker. - Why it matters: this is the exact dual-entrypoint trap §0.3 warns about. As wired, the SV-0.5 ping/pong (and, by the same defect, the pre-existing SyncPlay callback surface) is disconnected from the actual listener, so S-F28's half-open detection does not function in the resident path. - Fix direction: make the accepting worker and the callback-bearing worker the same instance — either (a) bind `onConnect/onMessage/onClose/onError/onWebSocketPong` (and the ping/reaper timers) onto `$wsWorker` in `start.php` (e.g. have `WebSocketServer` accept an injected Worker or expose a `bindTo(Worker $w)`), or (b) declare/run the `WebSocketServer` worker itself before `runAll()`. Then verify on the box: a real WS client that pongs survives ≥2 ping intervals, and a client killed with pongs suppressed is reaped. 2. **[LOW — accuracy of the stated teardown mechanism] `releaseStream()` has no production caller.** `grep` finds `releaseStream` referenced only in tests and the doc comments; no HTTP endpoint, `HttpHandler`, or middleware invokes it on stream end (`StreamLimitController` exposes get/update/list only). The worklog/comments call `releaseStream()` "the canonical stream-teardown path" for timer cancellation, but in production timers are only ever removed by the one-shot self-clear (~30s after the last request) and DB rows only decrement via the 60s `cleanupStaleStreams` sweep. This is **not** a leak (the self-clearing one-shot design bounds the timer count, as the implementer note acknowledges) and the AC "accounting decrements on stream end" is still met via the heartbeat-timeout sweep — so not blocking. Flagged only because the stated design overstates what runs in production; if explicit teardown is desired, wire `releaseStream()` into a real stream-end signal. 3. **[LOW — doc/comment inaccuracy] Reap latency is ~(limit+1)× the ping interval, not "~2×".** With the default `ping_not_response_limit=2`, a dead peer is reaped on the **third** sweep (sweep1 pending→1, sweep2 pending→2, sweep3 observes ≥2 and reaps), i.e. ≈90s at the 30s default — as `testPingSweepReapsNonRespondingConnection` itself demonstrates. The implementer note and the code comment say "~2× ping window." The AC ("within the ping window") is still loosely satisfied; adjust the wording (or reap when `pending >= limit` is reached *at ping time* if a tighter bound is wanted). **Verdict: 3 findings (1 HIGH requiring on-box verification / rewire, 2 LOW).** ## Fixer — SV-0.5 review findings — 2026-07-12 All 3 findings fixed. Files touched: `src/Server/WebSocket/WebSocketServer.php`, `start.php`, `src/Access/StreamSessionService.php`, `tests/Unit/Server/WebSocket/WebSocketServerTest.php`. ### Finding 1 (HIGH) — WS ping/pong bound to a worker that never listens Root cause confirmed by reading `start.php` + Workerman `vendor/`: `start.php` declares the real listener `$wsWorker` (pre-`runAll`), but `WebSocketServer`'s constructor built its OWN `Worker` (post-`runAll`, inside the forked child's `onWorkerStart`) and bound `onConnect/onMessage/onClose/onError/onWebSocketPong` to THAT throwaway worker. Workerman only `listen()`s workers created before `runAll()`, so the internal worker never accepted connections; the accepting `$wsWorker` had no callbacks. The Websocket protocol resolves pongs via `$connection->worker->onWebSocketPong` (= the accepting `$wsWorker`), so pongs never reached `recordPong()`, the pool was never populated via `onConnect`, and S-F28 half-open detection (and, by the same defect, SyncPlay message routing) was dead in the resident path. **Options considered:** (a) inject the real `$wsWorker` into `WebSocketServer` and bind the callbacks onto it; (b) have `WebSocketServer` declare/run its own worker before `runAll()` (would duplicate the listener + fight `start.php`'s container-building `onWorkerStart`); (c) copy callbacks onto `$wsWorker` in `start.php` by hand (leaks WS wiring into bootstrap, easy to drift). **Chosen: (a).** `WebSocketServer::__construct` now takes an optional third arg `?Worker $worker`. When provided it is used as `$this->worker` (the caller keeps ownership of `onWorkerStart` — we do NOT clobber it), and the new private `bindConnectionCallbacks()` binds `onConnect/onMessage/onClose/onError/` `onWebSocketPong` onto that real listener. When null (tests / SyncPlayWorker / `run()`) the old standalone behaviour is preserved (own worker + own `onWorkerStart`). `start.php` now passes `$w` (the `onWorkerStart`-supplied listening worker) as the third arg, so all callbacks — crucially the pong handler — bind to the worker that actually accepts on :8097. The reaper + ping timers are unchanged: they arm via `onStart()` which `start.php` calls inside `$w`'s `onWorkerStart`, so `Timer::add` registers in that same worker process, and they now operate over a pool that `onConnect` genuinely fills. New `getWorker()` accessor exposes the wired worker. Regression guard: `testCallbacksBindToInjectedListeningWorker` injects a listener worker (with a caller-owned `onWorkerStart`) and asserts `getWorker()` returns that same instance, that all four lifecycle callbacks AND `onWebSocketPong` are bound to it, and that the caller's `onWorkerStart` is NOT overwritten. This fails against the old code (callbacks would be on the internal throwaway worker). Dual-entrypoint: `public/index.php` has NO WS worker (verified — `grep` for `websocket|WebSocketServer|8097|wsWorker` returns nothing), so no mirroring is needed; the WS worker is resident-only (`start.php`). `SyncPlayWorker` (the self-listening reference pattern) is unused in both entrypoints (only referenced in its own docblock example), so it was left untouched. *[Erratum 2026-10-15: superseded twice over — `public/index.php` was since removed (`start.php` is the only entry point), and `SyncPlayWorker` itself was deleted outright by `22ce232c` (retire the unbound standalone bootstrap, R17-05).]* ### Finding 2 (LOW) — `releaseStream()` teardown wording overstated No clean stream-end hook exists: the streaming path is pure signed-URL HTTP GETs (direct + HLS segments); the client just stops requesting, and `active_streams` rows are removed only by the 60s `cleanupStaleStreams()` sweep. Chose the honest option (correct the wording, do NOT invent a fake hook). Reworded the `heartbeatTimerIds` property docblock, `registerHeartbeatTimer()` docblock, and `releaseStream()` docblock in `StreamSessionService` to state teardown in the resident HTTP path is TIMEOUT-DRIVEN (one-shot self-clear ~30s after the last request + the 60s stale sweep), and that `releaseStream()` is the EXPLICIT teardown path for callers that DO have a stream-end signal (currently tests). ### Finding 3 (LOW) — reap-latency figure corrected The "~2×" figure lived in the previous implementer note. Added an accurate comment in `WebSocketServer::onStart()` (ping-timer block): a dead peer is reaped on the sweep that OBSERVES `pendingPings >= limit`, i.e. the `(limit + 1)`th sweep, so with defaults (interval 30s, limit 2) reap latency is `~(limit + 1) x interval ≈ 90s`, not ~2x. (This note's Gap-1 "~2× ping window" line above is superseded by that figure.) ### Verification (this box) - `phpunit --filter 'WebSocketServer|StreamLimit|HttpHandler|StreamSession'` → **OK (86 tests, 182 assertions)** (was 85; +1 regression test). - `phpunit tests/Unit/Server/WebSocket tests/Unit/Access` → **OK (37 tests, 120 assertions)** (constructor-signature regression check across the WS/Access suites). - `phpstan analyze -c phpstan.neon.dist` → **[OK] No errors** (645/645). - `phpcs --standard=PSR12` on touched files → WebSocketServer.php + the test file **clean**; StreamSessionService.php only the 5 PRE-EXISTING >120-char warnings in `getActiveStreamsForProfile` (lines 370-375, untouched); start.php only the PRE-EXISTING line-5 file-header error (my diff starts at line 271). No NEW errors/warnings introduced. ### On-box verification STILL NEEDED Finding 1 is a resident-runtime wiring fix and `start.php` is OUTSIDE CI, so unit tests cannot exercise the real :8097 listener. Per §0.7 this warrants an on-box confirmation after deploy: connect a real WS client that pongs and confirm it survives ≥2 ping intervals, then kill a WS client (suppress pongs) and confirm it is reaped within ~(limit+1)× the ping interval, and confirm SyncPlay message routing works over the live socket. ## Reviewer (REVIEW-2) — SV-0.5 — 2026-07-12 Confirming review of the Fixer's changes for the 3 per-step findings (commits `1a54bc2b`, `1fbfacf7`, `238dced8`; diff `24cbd6a6..238dced8`). Read the actual current code (not the Fixer note): `WebSocketServer.php`, `start.php`, `StreamSessionService.php`, the regression test, and the Workerman `Protocols/Websocket.php` pong resolution. Verifications (this box): - `phpunit --filter 'WebSocketServer|StreamLimit|HttpHandler|StreamSession'` → **OK (86 tests, 182 assertions)**. - `phpstan analyze -c phpstan.neon.dist` → **[OK] No errors** (645/645). - `phpcs --standard=PSR12` on `WebSocketServer.php` + `StreamSessionService.php` → **0 errors**; the only 5 warnings are the PRE-EXISTING >120-char lines in `getActiveStreamsForProfile` (lines 370-375) — confirmed untouched (diff hunks are only at 35-45 / 128-145 / 152-172). No new phpcs/phpstan issues. Finding-by-finding confirmation: 1. **[HIGH — RESOLVED, on-box verify still open] WS ping/pong now binds to the real listening worker.** Confirmed: - `WebSocketServer::__construct` (WebSocketServer.php:79-104) takes optional `?Worker $worker`; when injected it becomes `$this->worker` WITHOUT the `onWorkerStart = [$this,'onStart']` assignment (that only happens in the else/standalone branch), so the caller's `onWorkerStart` is NOT clobbered. `bindConnectionCallbacks()` (124-132) binds onConnect/onMessage/onClose/ onError/onWebSocketPong onto that worker. - `start.php:239-298`: `$wsWorker` is declared BEFORE `runAll()` (real listener on :8097); its `onWorkerStart` receives the forked worker `$w` (=`$wsWorker` in-child) and passes `$w` as the 3rd ctor arg, then calls `onStart()`. So (a) the pong genuinely resolves on the accepting worker: `Protocols/Websocket.php:215` reads `$connection->worker->onWebSocketPong` and `$connection->worker` is `$wsWorker`=`$w`, which now carries the bound `onWebSocketPong` → `recordPong()`; (b) `onWorkerStart` is start.php's container-building closure, untouched; (c) the ping/reaper timers arm via `onStart()` inside `$w`'s `onWorkerStart`, so `Timer::add` registers in the same process whose `onConnect` fills the (singleton) `ConnectionPool` that `pingConnections()` iterates — pool and timers coincide; (d) null-worker path preserved: else-branch creates its own worker + `onWorkerStart`, and `run()`→`Worker::runAll()` still listens (tests / SyncPlayWorker / `run()`); *[Erratum 2026-10-15: SyncPlayWorker since deleted @`22ce232c`.]* (e) MessageHandler wiring intact (onMessage → handler, unchanged); (f) no double-listen — the resident path creates NO second Worker, so it cannot fight start.php's listener. - `public/index.php` has NO WS worker (grep for `websocket|WebSocketServer|8097|wsWorker` returns nothing) → no mirroring needed; correct. - Regression test `testCallbacksBindToInjectedListeningWorker` genuinely guards the pre-fix defect: it asserts `getWorker() === $listener` (the accessor did not exist pre-fix) and that all four lifecycle callbacks AND `onWebSocketPong` are `[$server, …]` on the INJECTED listener (pre-fix they bound to the throwaway internal worker), and that the caller-owned `onWorkerStart` is not overwritten. Fails against the old wiring. - Residual: this is a resident-runtime fix; `start.php` is OUTSIDE CI so unit tests cannot exercise the live :8097 socket. Per §0.7 an on-box confirmation remains the ONLY open item (a ponging client survives ≥2 ping intervals; a pong-suppressed client is reaped at ~(limit+1)×interval; SyncPlay routing works over the live socket). 2. **[LOW — RESOLVED] `releaseStream()` teardown wording corrected.** The `heartbeatTimerIds` / `registerHeartbeatTimer()` / `releaseStream()` docblocks now state teardown in the resident HTTP path is TIMEOUT-DRIVEN (one-shot self-clear ~30s after the last request + the 60s `cleanupStaleStreams()` sweep) and that `releaseStream()` is the explicit path for callers with a real stream-end signal (currently tests). Accurate; no behavior change; still not a leak (self-clearing one-shot bounds the count). 3. **[LOW — RESOLVED] Reap-latency comment corrected.** The `onStart()` ping-timer block now documents reap on the sweep that OBSERVES `pendingPings >= limit` = the `(limit+1)`th sweep → `~(limit+1)×interval ≈ 90s` at the defaults, matching `testPingSweepReapsNonRespondingConnection`. **Verdict: NO FINDINGS.** SV-0.5 is code/test-complete (all 3 prior findings resolved; suite green, phpstan 0, no new phpcs) — modulo the on-box confirmation of the resident :8097 ping/pong + SyncPlay routing (start.php is outside CI) and the pending Docs cycle. ## Implementer — X2/HB-2.1 server side — 2026-07-12 Built the phlix-server half of cross-repo sync point X2 (HB-2.1 "bodied relay >64KB"). Before this, a >64KB relayed request failed 400-malformed: the hub chunks large request bodies (RelayHttpRequestCodec HEAD/BODY/END tag-byte frames sharing one requestId, `RelayProxyManager.php:288-319`), but the server did `RelayHttpRequest::fromJson()` UNCONDITIONALLY on the first frame and threw on the tag-byte HEAD. The server was also not repinned to the shared request codec. ### 1. Repin phlix-shared (old → new) - `composer.json`: added a `path` repository `/home/sites/phlix/phlix-shared` (`symlink:false`) BEFORE the existing vcs repo, and lowered the constraint `detain/phlix-shared` `^0.19.0` → `^0.18.0` — MIRRORING the hub's convention exactly (hub `composer.json` uses the same path repo + `^0.18.0`). - `composer update detain/phlix-shared` → **v0.19.0 (ref 0fa2709c) → 0.18.0 (ref 216ea5dfa7faf2a422dbf0a1a4116442994e7c74)**. NOTE the version NUMBER drops but the CODE is a strict SUPERSET: the v0.19.0 tag commit (0fa2709) is an ANCESTOR of master HEAD 216ea5d, and the request-codec commits (008fcc1 subdomain, 216ea5d codec) sit ABOVE the v0.19.0 tag but were never tagged (the shared repo's composer.json `version` field was left at 0.18.0). So 216ea5d = everything in v0.19.0 PLUS `RelayHttpRequestCodec` / `RelayHttpRequestHead` / `RelayHttpRequestChunk`. This is the identical situation the hub already resolved. Lock diff is scoped to the single `detain/phlix-shared` package (verified by diffing the package list — only that one line changed). Codec vendored: `vendor/detain/phlix-shared/src/Relay/RelayHttpRequestCodec.php` (+ Head + Chunk) all present after `composer install`. ### 2. Reassembly in RelayConsumer::onHttpRequest (`src/Hub/RelayConsumer.php`) - Single-vs-chunked branch: `onHttpRequest` now peeks the first payload byte. The legacy single-frame JSON envelope always begins with `{` (0x7B); the chunked codec tags are HEAD 0x01 / BODY 0x02 / END 0x03 — disjoint sets, so the first byte unambiguously selects the path. `isChunkedRequestFrame()` matches the three tag bytes; anything else (incl. an empty payload) falls through to the UNCHANGED `RelayHttpRequest::fromJson()` legacy path (full back-compat, incl. the prior 400-on-garbage behaviour). - `onHttpRequestChunk()` mirrors the hub's response-side reassembly with a per-requestId accumulator map `requestAccumulators` (`array{head: RelayHttpRequestHead, body: string, size: int}`): HEAD opens an accumulator carrying method/path/headers; BODY appends raw bytes; END finalizes → builds the full `RelayHttpRequest(method,path,query,headers,body)`, calls `assertSafe()` (inheriting fromJson's method/path gate), then dispatches via the shared `dispatchEnvelope()` tail (extracted from the old onHttpRequest so both paths reuse dispatch+stream+log). - Abuse guards: body capped at `MAX_REASSEMBLED_REQUEST_BODY` (25 MiB) — overflow → 413 + accumulator dropped; concurrent assemblies capped at `MAX_CONCURRENT_REQUEST_ASSEMBLIES` (128) — excess HEAD → 503; duplicate HEAD → 400 + drop; BODY/END without HEAD → 400; malformed chunk/head-JSON → 400. - Accumulator lifecycle (no resident-worker leak): finalized+removed on END BEFORE dispatch; dropped on HTTP_CANCEL (`onHttpCancel` now calls `discardRequestAccumulator`); cleared wholesale in `handleDisconnect()` and `stop()` (tunnel teardown). ### 3. Dual entrypoints No bootstrap/DI change — the reassembly is entirely internal to RelayConsumer (only new private fields/methods/constants; constructor signature unchanged), so neither `start.php` nor `public/index.php` needed mirroring. ### Tests (`tests/Unit/Hub/RelayConsumerTest.php`, +8) - `test_http_request_chunked_reassembles_binary_body_and_dispatches` — feeds a real HEAD + N·BODY (>2 frames) + END for a 140,000-byte body covering the FULL byte range (chr(i%256) incl NUL/0xFF) via the real `RelayHttpRequestCodec::encode*`; asserts the dispatcher saw byte-identical `rawBody`, correct method/path/query/ headers + forwarded relay user, that nothing dispatched before END, a 200 streamed back on the same requestId, and the accumulator cleared to 0. - `test_http_request_legacy_single_frame_with_body_still_dispatches` — the `{`-prefixed JSON envelope path (PUT + small body) still dispatches, opens NO accumulator. - Guards: body-without-HEAD → 400; END-without-HEAD → 400; duplicate HEAD → 400+cleared; malformed HEAD JSON → 400; body overflow → 413+cleared (size seeded near the cap via reflection so no 25 MiB is shovelled through the framer); HTTP_CANCEL drops a partial assembly. All assert `pendingAccumulatorCount()==0` (reflection) so no throw escapes and nothing leaks. ### Verification (actual) - `composer update detain/phlix-shared`: `Downgrading detain/phlix-shared (v0.19.0 => 0.18.0)` … `Mirroring from /home/sites/phlix/phlix-shared`; lock diff scoped to that one package. - `ls vendor/detain/phlix-shared/src/Relay/RelayHttpRequestCodec.php` → exists (+ Head + Chunk). - `./vendor/bin/phpunit --filter 'RelayConsumer|RelayHttpRequest'` → **OK (45 tests, 227 assertions)** (8 new). - `./vendor/bin/phpstan analyze -c phpstan.neon.dist` → **[OK] No errors** (645/645). - `./vendor/bin/phpcs --standard=PSR12 src/Hub/RelayConsumer.php` → 0 errors. (The test file's snake_case method-name errors are the file's pre-existing convention across ALL methods and `tests/` is outside the `src/`-only phpcs gate.) FOLLOW-UPS (owned by the phase coordinator, not this task): hub emission unit test (RelayProxyManager >64KB → HEAD+N·BODY+END on one requestId) + the full end-to-end hub-emit → server-reassemble round-trip integration test. ## Reviewer — X2/HB-2.1 server side (post-deps verify) — 2026-07-12 Post-pause re-verification after the external deps change. Server HEAD is now `9fe18fa9 deps: source detain/phlix-shared from Packagist (^0.20.0), drop dev path repo`. The X2 implementer's OLD approach (dev path repo → v0.18.0, ref 216ea5d) has been REPLACED: `phlix-shared` is now sourced from Packagist `^0.20.0`. The exact ref the implementer pinned no longer applies, so this pass re-confirms the reassembly work survived the swap. ### (1) Master-green status — X2/HB-2.1 targeted gates (actual output) - `composer install` → `Nothing to install, update or remove` (lock in sync; only the known abandoned-package + PSR-4 skip notices, both pre-existing/cosmetic). - **Request codec vendored (^0.20.0):** `vendor/detain/phlix-shared/src/Relay/RelayHttpRequestCodec.php` (5874 B), `RelayHttpRequestHead.php` (5169 B), `RelayHttpRequestChunk.php` (1275 B), `RelayHttpRequest.php` (11172 B) — ALL PRESENT. `composer.lock` → `detain/phlix-shared 0.20.0`, dist type `zip`, ref `94458ab7…` (Packagist-sourced, no path repo). NOT a RED blocker — the reassembly code's codec dependency resolves. - `phpstan analyze -c phpstan.neon.dist` → **[OK] No errors** (645 files, 0 errors). - `phpunit --filter 'RelayConsumer|RelayHttpRequest'` → **OK (45 tests, 227 assertions)**. - `phpcs --standard=PSR12 src/Hub/RelayConsumer.php` → **0 errors**. Broader `phpunit --testsuite Unit` sanity (OUT OF SCOPE for this step): 4907 tests, 11 errors / 21 failures. All reds are in unrelated domains and NONE touch RelayConsumer / RelayHttpRequest / phlix-shared, and NONE are caused by the deps bump: - SV-4.13 command-builder drift: `FfmpegRunnerTest::testBuildTranscodeCommand*`, `FfmpegRunnerHlsTest::testBuildHlsCommand*`, `TranscodeManagerTest::*` (whole-file builder removals — separate step). - SV-2.8 stream drift: `ItemRepositoryTest::testAddStream*`. - Other pre-existing/domain-or-env reds: `ThemeMediaStreamControllerTest`, `PhotoControllerTest`, `AudiobookControllerTest` (Range requests), `BookProgressStoreTest`, `LibraryMetadataMatcherTest`, `SyncPlayManagerTest`, `LibraryScanWorkerTest`, `LibraryScanCommandTest`. These are tracked under their own steps; the deps swap only changed phlix-shared sourcing (path→Packagist, 0.18→0.20) and the relay-codec content is byte-for-byte the `@since 0.17.0` API the reassembly targets. The X2/HB-2.1 slice is GREEN. ### (2) Request codec confirmed vendored via ^0.20.0 `RelayHttpRequestCodec` / `RelayHttpRequestHead` / `RelayHttpRequestChunk` / `RelayHttpRequest` are all present in the Packagist-sourced `0.20.0` package. The codec constants are unchanged from the version the implementer coded against: `TAG_HEAD=0x01`, `TAG_BODY=0x02`, `TAG_END=0x03`, `MAX_BODY_CHUNK=65534`; chunk kinds `KIND_HEAD='head'`, `KIND_BODY='body'`, `KIND_END='end'`; `RelayHttpRequest(method, path, query, headers, body)` + `assertSafe()`; `RelayHttpRequestHead(method, path, query, headers)` + `withBodySize()`. No 0.18→0.20 API drift that affects the reassembly. ### (3) Confirming review of the reassembly (RelayConsumer::onHttpRequest + accumulator + tests) Reviewed `src/Hub/RelayConsumer.php:770-973` (branch/accumulator/finalize), `:1442-1452` (cancel), `:306-308`/`:1668-1675` (teardown), and `tests/Unit/Hub/RelayConsumerTest.php:819-1068`. Verified against the ^0.20.0 codec API: - First-byte branch (`isChunkedRequestFrame`, :826-833) tests exactly `RelayHttpRequestCodec::TAG_HEAD/BODY/END`; legacy JSON envelope begins `{` (0x7B), which cannot collide with 0x01/0x02/0x03 — unambiguous. Empty payload falls through to the legacy branch and is rejected 400 as before (back-compat preserved). - Per-requestId accumulator: HEAD opens (rejects duplicate HEAD → 400+clear; rejects when ≥128 concurrent → 503 without opening); BODY appends raw `$chunk->body` (rejects body-before-HEAD → 400; enforces the 25 MiB / 26214400-byte cap → 413+clear); END finalizes — accumulator is `unset` BEFORE dispatch (slow dispatch can't pin it; late duplicate END is a no-op), rebuilds the full `RelayHttpRequest` with the byte-identical concatenated binary body and calls `assertSafe()` (same method/path gate `fromJson` applies) before `dispatchEnvelope`. - Abuse guards all present: 25 MiB cap→413, 128-assembly cap→503, orphan BODY/END→400, duplicate HEAD→400, malformed chunk/head→400+clear. - No resident-worker leak: accumulator cleared on END, on decode error, on overflow, on duplicate HEAD, on missing-dispatcher, on HTTP_CANCEL (:1452), and the whole map is reset on stop (:307) and disconnect (:1675). - Tests genuinely exercise the REAL vendored codec: the binary-body test (`test_http_request_chunked_reassembles_binary_body_and_dispatches`, :819) builds a 140000-byte body spanning the full 0x00–0xFF range via `RelayHttpRequestCodec::encodeHead/chunkBody/encodeEnd`, asserts >2 BODY frames, asserts NO dispatch before END, and asserts the reassembled `rawBody` is byte-identical. Companion tests cover legacy single-frame-with-body (:890), body-before-HEAD 400 (:923), END-before-HEAD 400 (:941), duplicate HEAD 400+clear (:959), malformed HEAD 400 (:983), overflow 413+clear (:1005), and HTTP_CANCEL clears the pending accumulator (:1044) — each asserting the accumulator count returns to 0. **NO FINDINGS.** The X2/HB-2.1 server-side chunk reassembly survived the phlix-shared path→Packagist ^0.20.0 swap intact, matches the vendored codec API exactly, and is correct. ## Unit-suite RED triage (orchestrator, post-deps resume) — 2026-07-12 Gates GREEN: phpstan L9 0 errors, phpcs 0. Full `--testsuite Unit`: 4870 pass / 11 err / 21 fail / 5 skip. NONE env-dependent (withFile uses tempnam temp files; FfmpegRunner tests are pure command-string builders; DB mocked). Classified: **A — KNOWN-DRIFT (owned by step, expected):** - SV-2.8: ItemRepositoryTest::testAddStream{PersistsTrackMetadataColumns,InsertsStream} — INSERT param projection drift. - SV-4.13: FfmpegRunnerTest::testBuildTranscodeCommand* (×3) + FfmpegRunnerHlsTest::testBuildHlsCommand* (×5) — reference removed whole-file builders. **C — GENUINE (step marked [x] but red → REOPEN):** - **withFile Response-contract cluster (15 reds, ONE root cause):** Response::withFile() stores filePath/offset/length; Content-Range/Content-Length/body computed by PRIVATE finalizeFileHeaders() at send-time (Response.php:458, run at :398/:435/:542), so post-return `headers['Content-Range']`==null, `body`==''. Tests assert the pre-refactor EAGER contract. - SV-2.4 ThemeMediaStreamControllerTest ×7 (range/suffix/openended/clamp/200-body) - SV-2.5 PhotoControllerTest ×3 (full Content-Length + range) - SV-3.2 AudiobookControllerTest ×5 (range/full/binary-not-base64 — empty body) ⚠️ FIX RULE: VERIFY the deferred finalizeFileHeaders path actually emits correct Range output at emit-time BEFORE aligning tests; only update tests to the real deferred contract (or expose a test-visible finalizer). If runtime Range is actually wrong, fix the IMPL. Do NOT weaken assertions to hide a real bug. - **SV-3.5 LibraryMetadataMatcher ×2 (real logic gap):** testPerItemExceptionDoesNotAbortRun ERRORs — per-item resolver exception NOT caught, aborts whole run (missing per-item try/catch); testEmitsProgressLogEntriesAsItRuns — 'item not matched' progress log not emitted. - **SV-2.9 scanner rescan ×2 (real logic gap):** LibraryScanWorkerTest::testRunOnceProcessesRescanJob (rescan path calls unwired collaborator → swallowed into markFailed @LibraryScanWorker.php:170); LibraryScanCommandTest::testRescanFlagCallsRescanLibrary (--rescan returns exit 1 not 0). - **SV-3.2 BookProgressStore ×1:** testSaveAndRetrieveProgress — saveProgress passes raw float percent_complete (BookProgressStore.php:95) where test expects is_string($params[5]); determine correct persisted-type contract. - **SV-2.6 SyncPlayManager ×2:** testBroadcastToGroup{DeliversToAllConnectedMembers,ExcludesSpecifiedMemberIds} ERROR — ConnectionInterface::send():bool mock returns null (not stubbed willReturn(true)); backpressure reads the bool. Test-side stub gap (verify prod send() always returns bool). **Non-red hygiene note:** TranscodeManager.php:2161-2164 reads color_transfer/primaries/space without ?? → ~15 benign 'Undefined array key' warnings in TranscodeManagerTest (tests PASS); SV-1.1 area, add ?? guards (low priority). ## Fixer — withFile Response-contract cluster (SV-2.4/2.5/3.2) — 2026-07-12 Reopened the 15-red `withFile()` cluster (ThemeMediaStreamController ×7, PhotoController ×3, AudiobookController ×5). Per the FIX RULE, verified the deferred `finalizeFileHeaders()` path against Workerman's native encode (`vendor/workerman/workerman/src/Protocols/Http.php::encode()` lines 407-435) BEFORE touching tests. `finalizeFileHeaders()` is a faithful mirror of Workerman's encode: `bodyLen = length>0 ? length : fileSize-offset`; Content-Length=bodyLen; Accept-Ranges=bytes; `if (offset || length)` → Content-Range `bytes offset-offsetEnd/fileSize` + status 206. **Deferred path correct? — per case:** - **RANGE (bytes=2-5, suffix -3, open-ended 5-, clamp 8-100) → CORRECT.** Byte-emulated all four (probe): Content-Range/Content-Length/206/body window all byte-exact. These tests asserted the REAL contract, just eagerly (before finalize runs). → STALE-TEST. - **FULL non-range (offset 0, `length=fileSize`) → WRONG = REAL BUG.** All three controllers passed `withFile($path, 0, $fileSize)` (or `$start,$length` with length=full) for a plain non-Range GET. Because `length>0`, Workerman's `if ($offset || $length)` branch fires → it forces a **206 + Content-Range onto a request that never sent a Range** (RFC 7233 violation: 206 only for range requests). The controllers set status(200) but the event loop overrides to 206 on the wire. This is a genuine production defect, not test drift. **Verdict per controller:** - **ThemeMediaStreamController (SV-2.4):** REAL-BUG in the 200 path (`streamFile()`), STALE-TEST for the range paths. Fixed: full GET now calls `withFile($filePath)` (no window) → correct 200 + Content-Length, no spurious 206. - **PhotoController (SV-2.5):** REAL-BUG in `getFull()` no-range path, STALE-TEST for range. Fixed: `$isPartial = $rangeHeader !== null`; full GET passes length 0 → 200; range keeps `withFile($path,$start,$length)` → 206. - **AudiobookController (SV-3.2):** REAL-BUG in `streamAudiobook()` full-from-start path, STALE-TEST for range/binary. Fixed: `$isFullFromStart = $rangeHeader===null && $start===0` passes length 0 → 200. The chapter/offset resume window ($start>0) legitimately serves partial content and KEEPS its byte window (unchanged; `testStreamAudiobookResumesInChapter` still 200 at return). **Impl changes:** - `src/Server/Http/Response.php` — added public `materializeFileWindow(): self`. Collapses a `withFile()` response into a buffered one whose statusCode/headers/body equal EXACTLY the deferred wire output: runs the same private `finalizeFileHeaders()` the CGI `send()` path uses, then reads the identical offset/length window Workerman streams into `$body`. Production never calls it (still streams lazily via `toWorkermanResponse()`/`send()` — no heap buffering regression); it exists as the unit-test/inspection seam. Idempotent (clears filePath). Does NOT touch the SV-2.1 relay path or `toWorkermanResponse()`. - `ThemeMediaStreamController.php` (streamFile 200 branch), `PhotoController.php` (getFull), `AudiobookController.php` (streamAudiobook) — full non-range GET now passes NO byte window so the deferred path keeps a correct 200. **Test changes:** the 15 tests now call `$response->materializeFileWindow()` before asserting body/Content-Range/Content-Length — so they verify the TRUE deferred wire output (the same computation production emits), not a stale eager contract. No assertions weakened; every range/full case still proves correct status + Content-Range + Content-Length + windowed body. **Verification (actual output):** - `phpunit --filter 'ThemeMediaStreamController|PhotoController|AudiobookController'` → `OK (70 tests, 162 assertions)` (was 15 red). - `phpunit --testsuite Unit` → `Tests: 4907, Assertions: 38448, Errors: 11, Failures: 6, Skipped: 5`. Failures dropped 21→6; the 15 cleared. Remaining reds are ONLY other buckets: SV-2.8 ItemRepository::testAddStream* (2), SV-4.13 FfmpegRunner*/Hls* (8), SV-3.5 LibraryMetadataMatcher (2), SV-2.9 LibraryScanWorker/LibraryScanCommand (2), BookProgressStore (1), SV-2.6 SyncPlayManager (2). No ThemeMediaStream/Photo/Audiobook reds remain; no NEW reds introduced. - `phpstan analyze -c phpstan.neon.dist` → `[OK] No errors`. - `phpcs --standard=PSR12` on the 4 touched src files → 0 errors (1 PRE-EXISTING >120-char warning at PhotoController.php:387, outside my diff hunks 427-441). ## Fixer — SV-3.5 — 2026-07-12 Cleared the 2 genuine SV-3.5 reds (`LibraryMetadataMatcherTest::testPerItemExceptionDoesNotAbortRun` ERROR + `testEmitsProgressLogEntriesAsItRuns` failure). Both were real logic gaps in the SEQUENTIAL (non-coroutine) branch of `matchBatchConcurrently()` — PHPUnit CLI never enters a Swoole coroutine, so the sequential path is what tests exercise, and it lacked the per-item try/catch + `not matched` instrumentation that the coroutine branch already had. **Root cause:** - The coroutine fan-out branch (LibraryMetadataMatcher.php ~1936) already wrapped `executeMatchForItem()` in a per-item `try/catch (Throwable)` that logs a MEDIA-channel warning and continues via `finally`. The sequential branch (~1891-1904) called `executeMatchForItem()` bare, so a resolver throwing (`RuntimeException: resolver exploded`) propagated out of the batch loop → out of `matchLibrary()` → aborting the whole run (the remaining `item-good` was never processed). Hence the ERROR + wrong `{matched,processed}`. - The sequential branch only emitted `item matched` on a hit; a processed-but-unmatched item emitted nothing, so `item not matched` never reached the DEBUG log the test asserts. **Fix (impl only, no test contortion):** - `src/Media/Metadata/LibraryMetadataMatcher.php` — sequential branch: wrapped the per-item `executeMatchForItem()` in `try/catch (Throwable)`; on throw it logs `LibraryMetadataMatcher: item match failed; skipping` on the injected StructuredLogger (MEDIA channel) with `library_id/item_id/name/error` and `continue`s to the next item (the item still counts as `processed` since `$processed++` runs before the try). On a resolver miss (`$hit === false`) it now emits a per-item DEBUG `LibraryMetadataMatcher: item not matched` line mirroring the existing `item matched` shape. - Same `item not matched` DEBUG added to the coroutine branch's `else` for genuine parity, so both execution paths emit identical per-item progress instrumentation (not a test-only hack). - Preserved all SV-3.5 work: bounded-concurrency semaphore, coroutine fan-out, 429/backoff (in MetadataHttpClient), bounded cache — untouched. Sequential path still exact-sequential for non-coroutine callers. **Behaviour now:** one item's exception is isolated per-item, logged, and the run continues to process every subsequent item; `matchLibrary()` returns the full `{matched, processed}` count. `testPerItemExceptionDoesNotAbortRun` → `{matched:1, processed:2}`. Progress log emits start (INFO) + per-batch progress (INFO) + complete (INFO) + per-item `item matched`/`item not matched` (DEBUG). **Verification (actual output):** - `phpunit --filter 'LibraryMetadataMatcher'` → `OK (39 tests, 142 assertions)` (was 2 red). - `phpunit --testsuite Unit` → `Tests: 4907, Assertions: 38450, Errors: 10, Failures: 5, Skipped: 5, Risky: 3`. Errors 11→10, Failures 6→5 — exactly the 2 SV-3.5 reds cleared; no NEW reds. Remaining reds are ONLY the other triage buckets: SV-2.8 ItemRepository::testAddStream* (2), SV-4.13 FfmpegRunner*/Hls* (8), SV-2.9 LibraryScanWorker/LibraryScanCommand (2), SV-3.2 BookProgressStore (1), SV-2.6 SyncPlayManager (2). - `phpstan analyze -c phpstan.neon.dist` → `[OK] No errors`. - `phpcs --standard=PSR12 src/Media/Metadata/LibraryMetadataMatcher.php` → 0 errors (5 PRE-EXISTING >120-char warnings at lines 604/609/1227/1429/1436, all outside my ~1888-1955 diff region). SV-3.5 red cleared — step done-note stands; the 2 shipped-red tests are now green because the behaviour is correct. ## Fixer — SV-2.9 — 2026-07-12 **Verdict: REAL IMPL BUG (rescan silently did nothing) + two stale tests exposed by the same refactor.** Root cause traced to commit `19ca9b62` (SV-3.2 book/audiobook backends). It **gutted the base `LibraryManager::rescanLibrary()` into a no-op stub** — the pre-existing body (commit `266f957b`) did `DELETE FROM media_items WHERE library_id=? ` then delegated to `scanLibrary()` (which derives the library's configured paths AND routes music/photo/book/audiobook to their scanners). SV-3.2 replaced that with `return new ScanResult()` and *moved the logic nowhere*, so for the base manager (the one DI-injected into both the worker and the `library:scan` command, via `container->get(LibraryManager::class)`) **`library:scan --rescan` and every rescan job did nothing for movie/TV/generic libraries** — no delete, no rescan. It also changed the signature to `(libraryId, array $paths = [], ?callable $onProgress): ScanResult` and adapted the worker (added a `getLibrary()`+paths fetch) but never updated the two unit tests → the 2 reds: - `LibraryScanWorkerTest::testRunOnceProcessesRescanJob` red because the test asserted the old 2-arg `(libraryId, callable)` contract while the worker now calls 3-arg `(libraryId, paths, sink)`; the `with()` mismatch was swallowed into `markFailed()` at `LibraryScanWorker.php:170`. - `LibraryScanCommandTest::testRescanFlagCallsRescanLibrary` red (exit 1) because the mock cannot auto-generate a return value for the **`final` `ScanResult`** and threw (`Return value ... cannot be generated: Class "...ScanResult" is declared "final"`), which the command's catch turned into `Command::FAILURE`. (Reproduced both in isolation.) **Fix (logic RESTORED, not removed — per user steer):** - `src/Media/Library/LibraryManager.php` — rebuilt `rescanLibrary()` to actually work again: DELETE the library's items, then `scanLibrary()` (routes every type + streams progress), and return a real `ScanResult` (duration + a post-scan item count via new private `countLibraryItems()`). Kept the SV-3.2 signature/return so the Audiobook/Book subclass overrides stay compatible; the `$paths` arg is documented as base-ignored (base resolves paths from the library row). - `src/Media/Library/LibraryScanWorker.php` — dropped the now-unnecessary `getLibrary()`+paths adaptation; the rescan branch just forwards the progress sink: `rescanLibrary($libraryId, [], $this->scanProgressSink($jobId))` (base routes internally). - Tests updated to the correct current contract (NOT weakened — both still prove the rescan runs to completion and is never marked-failed): worker test asserts `(libraryId, array, callable)` + `willReturn(new ScanResult())`; command test adds `willReturn(new ScanResult())`. **Verification (actual output):** - `phpunit --filter 'LibraryScanWorker|LibraryScanCommand'` → `OK (14 tests, 53 assertions)`. - `phpunit --filter LibraryManager` → `OK (39 tests, 86 assertions)`. - `phpunit --testsuite Unit` → `Tests: 4907, Assertions: 38455, Errors: 10, Failures: 3, Skipped: 5, Risky: 3`. Failures 5→3 — exactly the 2 SV-2.9 reds cleared; no NEW reds. Remaining are ONLY the known buckets: SV-4.13 FfmpegRunner*/Hls* (8 err), SV-2.6 SyncPlayManager (2 err), SV-3.2 BookProgressStore (1), SV-2.8 ItemRepository::testAddStream* (2). - `phpstan analyze -c phpstan.neon.dist` → `[OK] No errors` (645 files). - `phpcs --standard=PSR12` on all touched files → 0 errors (one PRE-EXISTING >120-char warning at `LibraryManager.php:170`, an unrelated `getLibrary()` docblock example, outside my diff). ## Fixer — SV-3.2 BookProgressStore + SV-2.6 SyncPlay — 2026-07-12 Cleared the last 3 genuine-red triage entries. Root cause impl-vs-test per red: - **SV-3.2 BookProgressStore ×1 (IMPL fix).** `book_progress.percent_complete` is `DECIMAL(5,2)` (`migrations/075_book_progress.sql:11`). `saveProgress()` bound the raw float `25.5`; the test correctly asserted the DECIMAL-string persisted contract (`is_string($params[5])`). Fixed impl to bind `number_format($progress->percent_complete, 2, '.', '')` → deterministic `"25.50"` at the column scale, locale-safe (explicit '.' separator, unlike `sprintf('%.2f')`/LC_NUMERIC). Round-trip preserved: `getProgress()` reads it back with `(float)` (`testGetProgressReturnsProgressWhenFound` 7.5 → `"7.50"` → 7.5 still `assertSame`). Mirrors the sibling `AudiobookProgressStore` DECIMAL handling. Did NOT flip the assertion. - **SV-2.6 SyncPlayManager ×2 (TEST fix).** `ConnectionInterface::send(): bool` (`ConnectionInterface.php:40`); verified the only concrete impl `Connection::send()` (`Connection.php:113-124`) always returns bool (`return $result !== false;`) — so the null was a pure mock artifact. The two `testBroadcastToGroup*` tests stubbed `send()` with `willReturnCallback(... : void)` which returns null → PHPUnit's generated `: bool` mock method raised `TypeError`. Fixed the 5 callbacks to `: bool` + `return true;`. No false/backpressure branch added: `SyncPlayManager::broadcastToGroup` (`:1227`) does not consume the send() bool (SV-2.6's buffer-full skip/pause logic lives in MessageHandler/WebSocketServer, owned by SV-2.6 proper), so a false-return test here would assert nothing. Files: `src/Media/Library/BookProgressStore.php`, `tests/Unit/Session/SyncPlay/SyncPlayManagerTest.php`. Verification (actual output): - `phpunit --filter 'BookProgressStore|SyncPlayManager'` → `OK (46 tests, 125 assertions)`. - `phpunit --testsuite Unit` → `Tests: 4907, Assertions: 38485, Errors: 8, Failures: 2, Skipped: 5, Risky: 2.` The 3 targeted reds cleared; NO new reds. Remaining 10 reds are ONLY the known-drift buckets (owned by their own steps, untouched here): - SV-2.8: `ItemRepositoryTest::testAddStream{InsertsStream,PersistsTrackMetadataColumns}` (2 fail) - SV-4.13: `FfmpegRunnerTest::testBuildTranscodeCommand*` (3) + `FfmpegRunnerHlsTest::testBuildHlsCommand*` (5) = 8 err - `phpstan analyze -c phpstan.neon.dist` → `[OK] No errors` (645 files). - `phpcs --standard=PSR12` on both touched files → 0 errors. ## Fixer — SV-2.8 + SV-4.13 known-drift — 2026-07-12 Cleared the last two known-drift RED buckets → full Unit suite is now GREEN (0 err / 0 fail). **SV-2.8 (`ItemRepositoryTest::testAddStream{InsertsStream,PersistsTrackMetadataColumns}`) — STALE TEST, impl VERIFIED CORRECT (no impl change).** - `ItemRepository::addStream()` (`src/Media/Library/ItemRepository.php:1253-1291`) binds **17** params, matching the `media_streams` schema exactly: base `001` (id, media_item_id, stream_index, stream_type, codec, language, bitrate, width, height) + migration `071` (channels, title, is_default) + migration `073`/SV-1.1 (color_space, color_transfer, color_primaries, max_luminance, avg_luminance). The luminance binds are `is_numeric`-guarded `(float)` casts (DECIMAL(10,2) columns) — correct. The tests still asserted the pre-SV-1.1 `count($params) === 12`; the first 12 bindings are unchanged, so every existing value assertion ([1]–[11]) was still valid — only the count was stale and the 5 color columns were unasserted. - Fix (TESTS only, no assertions weakened): both tests updated to `count($params) === 17`; `testAddStreamInsertsStream` now also asserts params[12]–[16] are NULL when color meta is unset. Added `testAddStreamPersistsColorMetadataColumns` to strongly cover the SV-1.1 columns + the luminance guard: passes color_space/transfer/primaries + `max_luminance:'1000'` (numeric string → `1000.0`) + `avg_luminance:'N/A'` (non-numeric → NULL), asserting the exact persisted values. **SV-4.13 (`FfmpegRunnerTest::testBuildTranscodeCommand*` ×3 + `FfmpegRunnerHlsTest::testBuildHlsCommand*` ×5) — orphaned tests of REMOVED methods; deleted.** - CONFIRMED gone from `src/Media/Transcoding/FfmpegRunner.php` with ZERO callers (whole-repo grep, vendor excluded): `buildTranscodeCommand`, `buildHlsCommand`, `buildHwaccelCommand`. Only stale docref `@see` mentions remain (`TranscodeManager.php:2119`, `FfmpegRunner.php:512/517`) — cosmetic, do not break phpstan. - KEEP items all still present + tested: `buildCmafCommand`/`startCmafTranscode`/ `startCmafTranscodeWithSubtitles` (`:523/601/626`, covered by `testBuildCmafCommand*` ×5 in FfmpegRunnerHlsTest) and `buildGaplessSegmentCommand` (`:2339`, KEEP-but-unbuilt per §8 D2 — was untested before, unrelated to removed builders). - Per-segment REPLACEMENTS retain full coverage (so no real coverage dropped): `buildSegmentCommand` + `buildAudioSegmentCommand` → `testBuildSegmentCommand*`/`testBuildAudioSegmentCommand*` in FfmpegRunnerHlsTest; `buildHwaccelSegmentCommand` → FfmpegRunnerHwaccelTest (8 refs). - Deleted the 8 orphaned test methods: `testBuildTranscodeCommand`, `testBuildTranscodeCommandIgnoresNonScalarParams`, `testBuildTranscodeCommandHonoursValidWidthHeight` (FfmpegRunnerTest); `testBuildHlsCommandCopiesCompatibleStreams`, `testBuildHlsCommandEncodesAndScalesWhenRequested`, `testBuildHlsCommandHonorsVariantIndex`, `testBuildHlsCommandDefaultsSegmentSecondsWhenInvalid`, `testBuildHlsCommandForcesBrowserDecodableH264Profile` (FfmpegRunnerHlsTest). Both files retain their other still-valid tests (probe/isAvailable/getTranscodeDir/detached/CMAF/segment) — neither file became empty. No test for a still-live method was removed. - ⚠️ **NOTE (SV-4.13 impl incompleteness, out of my test-scope):** `buildTranscodeCommandWithProfile` (`FfmpegRunner.php:1163`) — classified REMOVE in §6 R1 — is STILL PRESENT (zero callers, zero tests, whole-repo grep). It does NOT affect the Unit suite or gates and no orphaned test references it, so I left the impl untouched (my two commits are test-only per the prescribed messages). Flagging for the SV-4.13 impl owner to complete the removal + fix the stale `buildHlsCommand`/`buildHwaccelCommand` docrefs. **Verification (actual output):** - `phpunit --filter 'ItemRepository|FfmpegRunner'` → `OK (193 tests, 554 assertions)`. - `phpunit --testsuite Unit` → `OK, but some tests were skipped! Tests: 4900, Assertions: 38479, Skipped: 11.` — **0 errors / 0 failures.** All triage buckets cleared; full Unit suite GREEN. (4907 → 4900 = removed 8 orphaned tests + added 1 color test; skips are env-dependent swoole/coroutine markTestSkipped, not reds.) - `phpstan analyze -c phpstan.neon.dist` → `[OK] No errors` (645 files). - `phpcs --standard=PSR12` on the 3 touched test files → 0 errors (only pre-existing >120-char warnings, all outside my edit regions). --- ## Implementer — 2026-07-12 — SV-4.7 WS auth enforcement (SECURITY) — audit gap list closed Closed all 6 gaps from the read-only audit (verdict PARTIAL). Auth is now enforced at the correct WS-handshake lifecycle stage, privileged events are gated, the SyncPlayAuthMiddleware is genuinely WIRED (not consolidated/queued), and the jwt_secret is plumbed through the resident path. **GAP 1 — moved auth from TCP-accept to the WS handshake.** `WebSocketServer::onConnect()` no longer reads `$_GET['token']` (empty/stale at TCP-accept under Workerman). It now just creates the Connection wrapper, pools it, sends the `connected` welcome. New `onWebSocketConnect(TcpConnection, Request)` runs at the handshake stage (bound via `bindConnectionCallbacks()` onto the SAME injected listening worker SV-0.5 wired — `$this->worker->onWebSocketConnect`), where the upgrade request's query string (`?token=`) is populated. It reads the token from the parsed `Workerman\Protocols\Http\Request::get('token')` and delegates validation. Workerman resolves the hook via `$connection->worker->onWebSocketConnect` (vendor Websocket.php:437), so binding it onto the real listener is load-bearing — same dual-entrypoint trap as SV-0.5. **GAP 2 — token-less connections now rejected when a secret is set.** `onWebSocketConnect` rejects (removes from pool + `close()`) when a JWT secret is configured and the token is missing/invalid/expired. Anonymous connections are allowed ONLY when no secret is configured (dev). Enforced via the middleware's `requireAuth=true` when a secret is present. **GAP 3 — jwt_secret plumbed into the WS server (resident path).** `config/server.php` websocket block gains `'jwt_secret' => getenv('JWT_SECRET') ?: ''` (SAME source AuthServicesProvider/JwtHandler use, so a login token validates on the WS too). `start.php` threads `$wsConfig['jwt_secret']` (falls back to the env directly). `WebSocketServer::__construct` builds a `SyncPlayAuthMiddleware($secret, requireAuth=true)` when the secret is non-empty, else leaves `$authMiddleware = null` (dev anonymous). `public/index.php` has NO WS worker (re-confirmed via grep) → no mirror needed. Production always has JWT_SECRET (boot guard refuses empty/default), so WS auth is enforced there. **GAP 4 — MessageHandler::handle() now has an auth gate.** Right after extracting `$event`, before the subscribe_dashboard branch and the generic dispatch, privileged events from an unauthenticated connection are rejected with a `Messages::TYPE_ERROR` / `error_code=NOT_AUTHENTICATED` (same shape SyncPlayManager uses) and NOT dispatched. `subscribe_dashboard` (now `WebSocketEvents::SUBSCRIBE_DASHBOARD`) is privileged, so unauthenticated dashboard now-playing streaming is blocked. Per-event SyncPlay gates in SyncPlayManager are unchanged (finer-grained; kept). **GAP 5 — SyncPlayAuthMiddleware WIRED (not deleted/consolidated).** Added `SyncPlayAuthMiddleware::authenticateConnection(Connection, ?string $token): bool` — the real, correct-lifecycle auth path. `WebSocketServer::onWebSocketConnect` delegates connect-time JWT validation to it; on a valid token it hands the derived `sub` straight to `Connection::setAuthenticated(true, $sub)` (fixing the old `$_GET['syncplay_user_id']` stash that didn't cooperate with sub-derivation). The legacy `onConnect(TcpConnection)` (TCP-accept `$_GET` path) is KEPT and marked `@deprecated` per §0.1 (no deletion), pointing to the new method. **Decision: WIRED, not consolidated → no Removal-Confirmation-Queue entry needed.** **GAP 6 — privileged-vs-public classification in WebSocketEvents.** Added `SYNCPLAY_PREFIX`, `SUBSCRIBE_DASHBOARD`, private `PUBLIC_EVENTS`/`PRIVILEGED_EVENTS` sets, and `isPublic()` / `isPrivileged()`. Privileged = every `syncplay_*` type + subscribe_dashboard/dashboard_now_playing + PLAYBACK_* + SESSION_*. Public = ping/pong/auth_request/connected. Unknown/server-only types are not privileged (no inbound handler dispatches them → safe no-op). Gap-4's gate consumes `isPrivileged()`. **Files changed (absolute):** - `/home/sites/phlix/phlix-server/src/Server/WebSocket/WebSocketServer.php` — remove $_GET auth from onConnect; add onWebSocketConnect handshake hook + authMiddleware field/ctor build; bind onWebSocketConnect. - `/home/sites/phlix/phlix-server/src/Server/WebSocket/SyncPlayAuthMiddleware.php` — new `authenticateConnection()`; deprecate legacy onConnect. - `/home/sites/phlix/phlix-server/src/Server/WebSocket/MessageHandler.php` — auth gate in handle(). - `/home/sites/phlix/phlix-server/src/Server/WebSocket/WebSocketEvents.php` — isPrivileged/isPublic + sets. - `/home/sites/phlix/phlix-server/config/server.php` — websocket.jwt_secret from JWT_SECRET. - `/home/sites/phlix/phlix-server/start.php` — thread $wsConfig['jwt_secret']; (also moved the file docblock above `declare` to clear a pre-existing phpcs file-header error). - Tests: `WsAuthenticationTest.php` (drive onWebSocketConnect via a real Request; **flipped** the Gap-2 test `testMissingTokenAllowsUnauthenticatedConnection` → `testMissingTokenRejectedWhenSecretConfigured` + added `testMissingTokenAllowedWhenNoSecretConfigured`); extracted `TestableSyncPlayManager` to its own file (`TestableSyncPlayManager.php`) to clear the pre-existing "one class per file" phpcs error; `MessageHandlerTest.php` (+4 gate tests); new `WebSocketEventsTest.php` (classification); WebSocketServerTest (+onWebSocketConnect binding assertion); `MessageHandlerFrameShapeTest.php` (authenticate the frame-shape connections so privileged events pass the gate). **Verification (actual):** - `./vendor/bin/phpstan analyze -c phpstan.neon.dist` → `[OK] No errors` (645 files). - `./vendor/bin/phpunit --testsuite Unit --filter 'WebSocket|WsAuthentication|MessageHandler|SyncPlay'` → `OK (183 tests, 536 assertions)`. - `./vendor/bin/phpcs --standard=PSR12` on all touched src + config + start.php → **0 errors**; touched test files → 0 errors (5 pre-existing >120-char WARNINGS in WsAuthenticationTest, non-blocking §0.2). - Pre-existing note: `tests/E2E/Session/SyncPlay/SyncPlayE2ETest` is RED on clean master (10 errors: mock `ConnectionInterface::send()` returns null — unrelated to this step; E2E suite not maintained green per the re-baseline). My change did not add E2E failures (9 after, ≤10 before). **OWED on-box verification (start.php outside CI, like SV-0.5):** deploy, then on :8097 confirm (a) a WS handshake WITHOUT `?token=` is rejected when JWT_SECRET is set; (b) a valid-token handshake authenticates and can drive SyncPlay; (c) an unauthenticated client's `subscribe_dashboard`/SyncPlay control message gets a NOT_AUTHENTICATED error and is not dispatched. NO FINDINGS (pending review) ## Reviewer (per-step) — SV-4.7 — 2026-07-12 Reviewed commit `fecd0ab5` (parent `62e7e1d5`) adversarially against the SV-4.7 Acceptance Criteria + S-F34 + §0 ground rules. Traced every enumerated review focus. Verified: - **SV-0.5 landmine cleared.** `onWebSocketConnect` is bound in `bindConnectionCallbacks()` onto `$this->worker`, which in the resident path is the INJECTED listening `$wsWorker` (`start.php:288` passes `$w`; ctor takes the `$worker !== null` branch, no re-create). Workerman resolves the hook via `$connection->worker->onWebSocketConnect`, so auth runs on the real :8097 listener. `WebSocketServerTest` now asserts this binding explicitly. - **No bypass.** Single inbound dispatch path (`onMessage` → `MessageHandler::handle`), gate at the very top of `handle()` before both the `subscribe_dashboard` branch and the generic `callbacks[$event]` dispatch. All SyncPlay handlers register `syncplay_*` types (verified in `SyncPlayManager::initialize` lines 200-213) → all caught by the `SYNCPLAY_PREFIX` privileged check. No `auth_request` handler exists → no post-handshake alt-auth path; `setAuthenticated` is called ONLY from `authenticateConnection` (handshake). Legacy `SyncPlayAuthMiddleware::onConnect` is `@deprecated` and wired NOWHERE (grep confirms). `SyncPlayWorker` (port 8098) is not instantiated in any prod boot path (start.php/index.php/bin) — and even if run it fails CLOSED (never authenticates → gate blocks privileged events), no bypass. *[Erratum 2026-10-15: the class was subsequently deleted entirely — `22ce232c` retired the unbound `SyncPlayWorker` standalone bootstrap (R17-05); there is no :8098 server path anymore.]* - **Defense-in-depth intact.** `SyncPlayManager::handle*` still gate on `$connection->getUserId()===null` → NOT_AUTHENTICATED. `authenticateConnection` hands the validated `sub` to `Connection::setAuthenticated(true,$sub)`; `getUserId()` returns it. No `$_GET['syncplay_user_id']` stash remains. - **Classification complete.** `isPrivileged` = `syncplay_*` prefix ∪ {subscribe_dashboard, dashboard_now_playing, PLAYBACK_*, SESSION_*}; PUBLIC = {ping,pong,auth_request,connected}. All 19 `Messages::TYPE_*` wire constants are `syncplay_`-prefixed → fully covered. Unknown types are non-privileged but have no inbound handler (safe no-op). Liveness ping/pong stay public. - **jwt_secret plumbing consistent.** WS reads `getenv('JWT_SECRET')` (config/server.php + start.php fallback) — same source as `AuthServicesProvider`/`JwtHandler`; middleware builds `new JwtHandler($secret)` identically, so a login token validates on the WS. `assertSecretConfigured()` (start.php:54) refuses to boot without a real JWT_SECRET, so `authMiddleware` is always non-null in prod (the dev-anonymous branch is unreachable on a booted prod server). `public/index.php` has no WS worker (confirmed) → no FPM mirror needed. - **Flipped test genuine.** `testMissingTokenRejectedWhenSecretConfigured` asserts close + empty pool (opposite of the old `testMissingTokenAllowsUnauthenticatedConnection`); `onWebSocketConnect` didn't exist pre-fix, so the semantic flip is real. `testMissingTokenAllowedWhenNoSecretConfigured` covers the dev branch. - **No TOCTOU.** WS protocol delivers no app messages before handshake; `onWebSocketConnect` (auth) runs during the handshake, before any `onMessage`, in the single event loop. Rejection removes from pool + `close()`. The null-`findConnection` early-return fails closed (`onMessage` also requires the wrapper in-pool). Gates re-run: phpstan L9 `[OK] No errors` (645 files); `phpunit --testsuite Unit --filter 'WebSocket|WsAuthentication|MessageHandler|SyncPlay'` → OK (183 tests, 536 assertions); phpcs PSR12 on all touched src/config/start.php → clean. Confirmed `SyncPlayE2ETest` red (9 errors, mock `send()` returns null) is PRE-EXISTING on clean master and unrelated to this step. NO FINDINGS --- ## Implementer — SV-3.1 FOUNDATION (a + b0 + e) — 2026-07-12 Owns the "wire the DVR into production boot" concern. Sub-steps SV-3.1c (scheduler Timers), SV-3.1d (comskip/media_items registration), SV-3.1f (timeshift) remain for follow-up sub-steps and are intentionally NOT touched here. ### SV-3.1a — kill the fake getmypid() recording (Recorder.php) `startRecording()` no-tuner branch (was `Recorder.php:507-541`): previously, when no tuner stream URL resolved, it marked the row `recording` with `pid=getmypid()` — a phantom capture with no ffmpeg behind it (violated §0.1). Now it logs a warning, calls `updateRecordingStatus(FAILED, 'No tuner available')` and returns false: pid stays NULL, no `activeRecordings` entry, no fake process. The spawn-success path is unchanged. Consequence in recovery: a due `scheduled` row with no wired tuner is counted `scheduled_skipped` (not `rearmed`) and left `failed`. ### SV-3.1b0 — DI factory: fully-wired Recorder + LiveTvManager + RecordingScheduler - NEW `src/Common/Container/Providers/LiveTvServicesProvider.php` — registered in `ContainerFactory::defaultProviders()` (index 9, before WebPortal) so BOTH entrypoints (`public/index.php` CGI + `start.php` daemon) resolve the same stack. Every binding is a PHP-DI singleton = one instance per worker. Defines: - `ChannelManager`, `GuideManager` (DB + livetv log channel). - `TunerDriverInterface` → HDHomeRun primary driver (the default-enabled driver LiveTvManager treats as primary), built from `livetv.hdhomerun`. - `ComskipLifecycleManager` → built from `livetv.comskip` (ComskipRunner + EdlParser + Integration); passed to the Recorder ctor which registers its enqueue as an onComplete hook. (No media_items INSERT / RecordingHooks — that is SV-3.1d.) - `Recorder` → FULLY wired ($db, storage_path, max_storage_bytes, livetv logger, comskip lifecycle manager, ffmpeg path). Built with `liveTvManager=null` to break the Recorder↔LiveTvManager cycle. - `LiveTvManager` → resolves the shared Recorder singleton, constructs itself, then calls `$recorder->setLiveTvManager($this)` — closing the cycle so `resolveTunerStreamUrl()` is reachable. Every real usage path (getLiveTvStreamController, RecordingScheduler, boot recovery, AdminLiveTvController) resolves LiveTvManager, so the link is always established. - `RecordingScheduler` → resolves LiveTvManager first (links the recorder), then the shared Recorder + manager. (Object only; its Timers are SV-3.1c.) - `config/server.php` now `require`s `config/livetv.php` as `$config['livetv']` (mirrors the ffmpeg/hub/relay pattern) → reaches BOTH entrypoints via `app.config['livetv']`. - `Application::getLiveTvStreamController()` now resolves `LiveTvManager` from the container and uses `$liveTvManager->getRecorder()` — the ONE wired Recorder — instead of `new Recorder($db, $storagePath)` (which had no ffmpeg/comskip/manager). Existing recording- stream route (`Application.php:1462-1464` → LiveTvStreamController :63-89) unchanged. ### SV-3.1e — boot recovery in start.php (daemon only) `start.php` HTTP worker `onWorkerStart`, gated on `$w->id === 0` so it runs EXACTLY ONCE per boot (not 14×): resolve `LiveTvManager` (links the recorder) and call `bootstrap()` → `Recorder::resumeActiveRecordings()` (re-attach live children, fail orphans, re-arm due). Wrapped in try/catch so a DVR-recovery failure never stops the worker serving. Runs OUTSIDE any coroutine (mirrors the SV-0.1 hwaccel probe precedent); `resumeActiveRecordings()`'s process checks + detached spawns are ordinary blocking calls valid at boot — no coroutine-only work to guard. NOT wired in `public/index.php` (single-shot CGI must not spawn recovery/timers per §0.3). ### Tests - `tests/Unit/LiveTv/RecorderRecoveryTest.php`: repurposed the old `testScheduledRecordingWithPastStartTimeIsRearmed` (asserted the fake-PID re-arm) → `testScheduledDueRecordingWithNoTunerIsSkippedNotRearmed` (rearmed=0, scheduled_skipped=1); added `testStartRecordingWithNoTunerMarksFailedWithNoFakePid` (SV-3.1a: returns false, 0 active recordings, exactly one UPDATE to status=failed, never status=recording, never a getmypid() PID). - NEW `tests/Unit/Common/Container/Providers/LiveTvServicesProviderTest.php`: `testContainerYieldsFullyWiredRecorder` (reflection — liveTvManager linked, ffmpegPath from config, storage/maxBytes from dvr config, comskip onComplete hook present) + `testStackIsSharedSingletons` (Recorder/LiveTvManager/RecordingScheduler share one instance). - `tests/Unit/Common/Container/ContainerFactoryTest.php`: provider count 13→14, LiveTv asserted at index 9, later providers reindexed. ### Verification (actual) - `phpstan analyze -c phpstan.neon.dist` → **[OK] No errors** (646 files). - `phpunit --testsuite Unit --no-coverage` → **4923 tests, 0 failures** (4 warnings / 5 skipped, pre-existing). `--filter 'Recorder|LiveTv|RecordingScheduler|LiveTvServicesProvider'` → 283 OK. - `phpcs --standard=PSR12` on touched src (Recorder, LiveTvServicesProvider, ContainerFactory, Application) → **0 errors** (6 pre-existing >120-char warnings on untouched lines). - `php -l start.php` + `php -l public/index.php` → no syntax errors. ### On-box verification OWED (start.php is outside CI) Deploy, restart phlix-server with active/scheduled recordings, confirm: (1) recovery re-attaches live ffmpeg children and marks orphans failed; (2) the boot log line "DVR boot recovery complete" fires exactly once (worker id 0); (3) a schedule with no available tuner is marked failed (no phantom getmypid recording). ### Follow-up sub-steps (NOT done here) SV-3.1c scheduler Timers · SV-3.1d comskip EDL→chapters + media_items registration · SV-3.1f timeshift stream. LiveTvStreamController timeshift is still a 501 stub (SV-3.1f). ## Reviewer (SV-3.1 foundation: a + b0 + e) — 2026-07-12 Reviewed commit `39899c70` (diff `fecd0ab5..39899c70`) — the DVR foundation only (a/b0/e). Verified locally: **phpstan L9 `-c phpstan.neon.dist` = [OK] 0 errors** (646/646); `phpunit LiveTvServicesProviderTest + ContainerFactoryTest + RecorderRecoveryTest` = **20/20 OK (80 assertions)**; **phpcs PSR-12 = 0 errors** on the changed files (only pre-existing >120-char warnings on untouched lines). Reviewed against foundation scope; c/d/f/g/h are plan-deferred and their absence is not a finding. Confirmed CORRECT (high confidence): - **b0 DI coherence:** every ctor the provider calls matches the real signature — `Recorder($db, storagePath, maxStorageBytes, logger, ComskipLifecycleManager, ffmpegPath, null)`, `LiveTvManager($db, ChannelManager, GuideManager, Recorder, TunerDriverInterface, logger)`, `RecordingScheduler($db, Recorder, LiveTvManager, logger)`, plus ComskipLifecycleManager/ComskipIntegration/ComskipRunner/ ComskipEdlParser/HdHomeRun{Discovery,ApiClient,TunerDriver}/ChannelManager/GuideManager. The Recorder↔LiveTvManager cycle is broken correctly: Recorder built with `null` manager, LiveTvManager factory calls `$recorder->setLiveTvManager($manager)` on the SAME PHP-DI singleton, and RecordingScheduler resolves LiveTvManager first so the back-ref is set before it receives the recorder. `logger.livetv` (CoreServicesProvider channel alias → StructuredLogger), `Connection::class` and `app.config` all resolve. Config keys the provider reads (`hdhomerun.ssdp_timeout_secs`, `comskip.{binary_path,queue_processing,max_concurrent}`, `dvr.{storage_path,max_storage_bytes}`, top-level `storage_path`, `dvbt.ffmpeg_path`) all exist in `config/livetv.php`. - **b0 wired-Recorder usage:** `Application::getLiveTvStreamController()` now resolves `LiveTvManager` (which links the shared Recorder) and passes `$liveTvManager->getRecorder()` — the one wired singleton — to the stream controller. The only `new Recorder(`/`new LiveTvManager(` in src/ are in the provider; no second unwired instance remains. The removed `createDatabaseConnection()` call has seven other live callers (not orphaned). - **a getmypid() removal:** the no-tuner branch marks the row FAILED ('No tuner available'), returns false, adds NO `activeRecordings` entry, and never spawns ffmpeg; `pid` stays NULL (the row was `scheduled`, pid never set; `updateRecordingStatus` does not touch pid). No orphaned/partial state. Guarded by `testStartRecordingWithNoTunerMarksFailedWithNoFakePid` (asserts no getmypid PID is bound) and `testScheduledDueRecordingWithNoTunerIsSkippedNotRearmed`. - **DUAL-ENTRYPOINT (§0.3):** `LiveTvServicesProvider` is registered in `ContainerFactory` (13→14), which BOTH `public/index.php:72` and `start.php:154` call via `ContainerFactory::create($config)`; `config/server.php` now `require`s `config/livetv.php`, and both entrypoints load `config/server.php`. The `getLiveTvStreamController()` change lives in `Application`, which only the daemon builds (the CGI path dispatches via `Router`+`WebPortalRouter` and never constructs `Application` nor its LiveTv route), so no CGI mirror is required and no CGI behavior changed. `bootstrap()` recovery is intentionally start.php-only. The `$this->container === null` throw in `getLiveTvStreamController()` is unreachable in practice (Application's ctor requires a non-null container). - **e worker-0 gating:** the recovery block sits inside `$httpWorker->onWorkerStart` (count=14) gated on `(int) $w->id === 0`, so it fires exactly once per boot — consistent with the repo's existing `(int) $w->id` usage in the same closure. `$container`, `LoggerFactory`, `LogChannels::LIVETV` are all in scope/imported. `bootstrap()` resolves LiveTvManager (linking the Recorder) BEFORE calling `resumeActiveRecordings()`, so tuner resolution works during re-arm. Wrapped in try/catch so a recovery failure never stops the HTTP worker. - **Swoole/coroutine (§0.3):** recovery runs at boot in `onWorkerStart`, OUTSIDE any coroutine, so the blocking process checks / detached spawns reachable via `resumeActiveRecordings()→startRecording()` are valid there (same as the adjacent hwaccel probe); the curated hook mask only affects in-coroutine work. All DB access is via `Workerman\MySQL\Connection` (`Connection::class`), no raw PDO. (The scheduler/timed-stop Timers that WOULD need `getCid()>0`/`Coroutine\System::exec` guards are SV-3.1c, deferred — not in this commit.) - **Security:** storage_path is a trusted `config/livetv.php` value; `getRecordingPath()` composes it with an internal UUID `recordingId` (no user input), so no path-traversal vector in the foundation; the DI/recovery wiring opens no unauth path (timeshift endpoint is still the 501 stub, SV-3.1f). - **No SV-4.7 regression:** the commit touches only config/server.php, ContainerFactory, Recorder, Application::getLiveTvStreamController, and the HTTP-worker `onWorkerStart` in start.php — it does not touch the :8097 WS worker, its handshake auth, or any WS wiring landed by `fecd0ab5`. Benign observations (NOT findings — no action required): (1) in-memory `activeRecordings` is populated by recovery only on HTTP worker 0, so other workers' Recorder singletons start empty — inherent to the per-worker-singleton design and harmless for the foundation (DB is source of truth; the stream controller only does path lookups; cross-worker state is an SV-3.1f/timeshift concern). (2) `Application::getLiveTvStreamController()` recomputes `storagePath` from config inline with the same precedence the provider's `dvrStorage()` uses, so the two cannot diverge given identical config keys. **Verdict: NO FINDINGS.** ## Implementer — SV-3.1c (scheduler Timer + timed-stop + padding fix) — 2026-07-12 Sub-step **c** on top of the foundation (`39899c70`). Wires the production scheduler Timer, the per-recording timed stop, the safety-net scan, and fixes the padding bug. NOT marked done — Review/Test pending. **Git NOT run here** (Phase Coordinator owns the git cycle); working tree carries the change for the coordinator to commit/push in two commits (impl + tests, messages below). ### The padding bug + the fix (authoritative in Recorder) `scheduleRecording()` persists the RAW programme `end_time` (guide boundary) + a separate `post_padding_seconds` column — it does NOT fold padding into `end_time`. The old `endRecording()` docblock/comment FALSELY claimed "end_time already = end_time + post_padding" and just stopped immediately. Fix: padding is now applied at STOP time, authoritatively in the Recorder, and NEVER folded into the stored `end_time` (so schedules keep true boundaries and padding can't double-count). One formula, three consumers, all in `Recorder`: - `Recorder::effectiveEndTime(int $endTime, int $postPadding): int` — the single formula (`end_time + max(0,padding)`); used by the scheduler to compute the one-shot timer delay. - `Recorder::getRecordingsDueToStop(?int $now=null): array` — the scan, expressing the formula in SQL: `status='recording' AND (end_time + COALESCE(post_padding_seconds,60)) <= now`. - `Recorder::endRecording()` — rewritten as the AUTHORITATIVE timed-stop entry. Live-in-memory → `stopRecording()` (kills ffmpeg, status→completed). Orphan safety net (row still `recording` but no in-memory handle on this worker, e.g. timer lost across restart) → kill any live stored pid + UPDATE status=completed + fire onComplete, so the scan can't loop forever. Corrected the misleading comment. ### Scheduler (RecordingScheduler) — start + timed-stop - `processDueRecordings()` (starts) now arms a **per-recording one-shot** `Workerman\Timer` after a successful `startRecording()`, at `effectiveEndTime(end_time, post_padding) - now` (min 1s), keyed in `stopTimerIds` (guarded `class_exists(\Workerman\Timer::class)`, `[], false` one-shot; idempotent re-arm; `Timer::del` on cancel). The timer callback (`fireStopTimer`) wraps `endRecording()` in try/catch. - `processCompletedRecordings()` (NEW safety-net scan) — iterates `recorder->getRecordingsDueToStop()`, calls the authoritative `endRecording()` per id, cancels any lingering timer; each stop in its own try/catch so one failure can't abort the scan. - `tick()` (NEW) — runs BOTH passes; this is what the production Timer calls. - `activeStopTimerCount()` (NEW, test observability). ### Production Timer wiring (start.php, daemon-only, worker 0) Added a periodic `\Workerman\Timer::add($schedulerInterval, fn → $scheduler->tick())` inside the HTTP `onWorkerStart`, gated `(int)$w->id === 0` (same gate as the SV-3.1e boot recovery) so it runs on ONE worker not 14. Cadence from `config/livetv.php` `dvr.scheduler_interval_seconds` (default **30s**), sanitized. Wiring + tick body both wrapped in try/catch (a scan error can never kill the worker) and logs "DVR scheduler timer armed". NOT mirrored in `public/index.php` (CGI runs no timers — dual-entrypoint §0.3 satisfied; no ctor/DI signature changed, DI via the existing `LiveTvServicesProvider` singletons). ### Coroutine/Swoole correctness (§0.3) The Workerman Swoole event adapter wraps EVERY timer callback in `Coroutine::create()` (`Events/Swoole.php::safeCall`, verified), so `getCid()>0` holds inside both the periodic tick and the one-shot stop callbacks → the hooked-PDO DB work in `tick()`/`endRecording()` runs in a valid coroutine context. No NEW subprocess spawn/kill is introduced by this sub-step (the stop reuses the foundation's `terminateRecording()` which uses `posix_kill` — a syscall, not exec — with a `shell_exec` fallback only when posix is absent; `SWOOLE_HOOK_NATIVE_CURL`/exec mask untouched). All new callbacks additionally have explicit try/catch on top of `safeCall`'s. ### Files changed - `src/LiveTv/Recorder.php` — `endRecording()` rewrite (authoritative padding + orphan reconcile); NEW `effectiveEndTime()`, `getRecordingsDueToStop()`. - `src/LiveTv/Recording/RecordingScheduler.php` — `stopTimerIds` state; `processDueRecordings()` arms one-shot stop timer; NEW `tick()`, `processCompletedRecordings()`, `activeStopTimerCount()`, `scheduleStopTimer()`, `fireStopTimer()`, `cancelStopTimer()`. - `start.php` — worker-0 periodic scheduler Timer wiring (after the boot-recovery block). - `config/livetv.php` — NEW `dvr.scheduler_interval_seconds` (default 30). ### Tests (added/extended) - NEW `tests/Unit/LiveTv/RecorderTimedStopTest.php` (5): `effectiveEndTime` applies/clamps padding; `getRecordingsDueToStop` scan SQL asserts `end_time + COALESCE(post_padding_seconds, 60)` + `status='recording'` + `now` bind (**the padding-applied assertion**); `endRecording` false when not found; `endRecording` reconciles an overdue `recording` row → exactly one UPDATE to COMPLETED + onComplete fires. - EXTENDED `tests/Unit/LiveTv/Recording/RecordingSchedulerTest.php` (+4, +`new Worker()` in setUp + `fakeResult`): starting a due recording arms exactly one stop timer via `effectiveEndTime(end_time, post_padding)` (mock `expects(...)->with($endTime, 90)` — **padding applied in the timer path**); scan ends all due recordings; scan isolates a failure (1 ended, 1 error); `tick()` runs both passes. ### Verification (actual) - `./vendor/bin/phpstan analyse -c phpstan.neon.dist` → **[OK] No errors** (646 files). - `./vendor/bin/phpunit --testsuite Unit --no-coverage` → **Tests: 4931, 0 failures, 0 errors** (4 warnings / 8 skipped, pre-existing). `--filter 'RecorderTimedStop|RecordingScheduler'` → 14 OK; `--filter 'Recorder|RecordingScheduler|LiveTvServicesProvider'` → 43 OK. - `./vendor/bin/phpcs --standard=PSR12` on `src/LiveTv/Recorder.php` + `RecordingScheduler.php` → **0 errors** (2 pre-existing >120-char warnings on untouched lines 191/1538 of Recorder). `phpcs` on `start.php` + both test files → clean. ### Intended commits (for the Coordinator) 1. `transcode/livetv: SV-3.1c scheduler timer + timed-stop at end_time+post_padding + padding fix` → Recorder.php, RecordingScheduler.php, start.php, config/livetv.php 2. `SV-3.1c tests: timed-stop padding scan + per-recording stop timer + endRecording reconcile` → RecorderTimedStopTest.php, RecordingSchedulerTest.php ### On-box verification OWED (start.php outside CI) Deploy + restart with a `scheduled` (due) and an active `recording` row and confirm: (1) "DVR scheduler timer armed" logs once (worker 0); (2) a due schedule starts within one tick and a per-recording stop timer is armed; (3) an in-progress recording stops at `end_time + post_padding` (timer path) and, after a mid-recording restart, the scan stops it within ≤ scheduler_interval. ### Seams left for later sub-steps (NOT done here) - **d** — register the completed `.ts` as a `media_items` row + wire comskip EDL→chapters to the real `media_item_id` (RecordingHooks still has no caller; onComplete fires but no INSERT). - **f** — timeshift endpoint (still the 501 stub at `LiveTvStreamController.php:~129`). - **g** — storage accounting on real files. **h** — `LiveTvStreamController` tests. ## Reviewer (per-step) — SV-3.1c — 2026-07-12 Reviewed `git diff 1cc85d3f..89f3f35f` (impl `50d3e992` + tests `89f3f35f`): Recorder padding authority + `getRecordingsDueToStop`/`endRecording` rewrite, RecordingScheduler `tick()`/ `processCompletedRecordings()` + per-recording one-shot stop timers, worker-0 periodic Timer in start.php, `dvr.scheduler_interval_seconds`. Gates run here: phpstan L9 `-c phpstan.neon.dist` on Recorder.php + RecordingScheduler.php = **[OK] 0 errors**; phpunit `--filter 'RecorderTimedStop|RecordingScheduler'` = **OK (14 tests, 37 assertions)**. **Check #1 (padding-default consistency) — PASS (no divergence).** All paths default post_padding to **60** when NULL/absent: scan SQL `COALESCE(post_padding_seconds, 60)` (Recorder.php:907); timer path `RowAccess::int($row,'post_padding_seconds',60)` (RecordingScheduler.php:269); `endRecording` reads `mapRecording()` which coerces via `RowAccess::int(...,60)` (Recorder.php:1587) so its `is_int(...)?:60` branch always sees an int (and is used only for logging, not gating); config `default_post_padding_seconds`=60 (livetv.php:362); column `INT NOT NULL DEFAULT 60` (mig 012a:42, 013:13/28). Timer path and scan path compute the same effective stop for the NULL/default row. Not a finding. **Checks #5, #6, #7, #8, #9 — PASS.** #5 worker-0 gate `(int)$w->id===0` at start.php:232 mirrors the SV-3.1e recovery gate at :200; Timer is repeating (2-arg `Timer::add`, persistent default). #6 verified Workerman `Events\Swoole::add()` routes one-shot (`Timer::after`) AND repeating (`Timer::tick`) callbacks through `safeCall`→`Coroutine::create` (vendor Swoole.php:69/105/286) → `getCid()>0`, so `terminateRecording` uses `Coroutine::sleep` (non-blocking) and hooked PDO can yield; stop reuses `posix_kill` (no hooked exec; `shell_exec` fallback is pre-existing and unreached when posix_kill present); no exit/die/blocking-sleep introduced. #7 no ctor/DI signature changed (only a private field + methods added; resolved via existing singleton) → no index.php mirror required; timer daemon-only. #8 nothing stubbed/deleted; d/f/g/h left as seams. #9 padding assertions genuine on BOTH paths (timer: `effectiveEndTime($endTime,90)`; scan: `end_time + COALESCE(post_padding_seconds, 60)` SQL) and the reconcile test asserts exactly one onComplete + one COMPLETED UPDATE — all would fail pre-fix (orphan returned false / no timer armed). ### Findings (3), most-severe first 1. **[MEDIUM] Double-completion race — the safety-net scan does not exclude in-flight recordings and there is no atomic status compare-and-swap.** `Recorder::getRecordingsDueToStop` (src/LiveTv/Recorder.php:900-918) selects rows purely by DB `status='recording' AND effectiveEnd<=now`, with no exclusion of recordings still live in `$this->activeRecordings` on this worker or holding a pending one-shot stop timer. Neither `stopRecording` (Recorder.php:733-775) nor `endRecording`'s reconcile UPDATE (Recorder.php:~838) guards the completion with a conditional `WHERE ... status='recording'` + affected-rows check. Because `terminateRecording` (Recorder.php:1055-1068) parks in a `Coroutine::sleep(0.1)` loop for up to ~5s (SIGTERM grace) BEFORE `stopRecording` unsets `activeRecordings` (:753) and writes the completion UPDATE (:758), the row stays `status='recording'` + in `activeRecordings` for that whole window. Under the Swoole runtime the one-shot stop-timer coroutine and each 30s scan-tick coroutine interleave at those yields. *Failure scenario:* a recording whose effectiveEnd falls within ~5s of a scan tick is processed by BOTH the one-shot timer and the concurrent scan (or two scan re-entries) → `fireOnCompleteCallbacks` fires twice and the completion UPDATE runs twice. Harm today is bounded (onComplete is a no-op until SV-3.1d, double UPDATE is near-idempotent), but once SV-3.1d wires comskip / media_item registration into onComplete this becomes a double comskip / double media-item insert / double storage accounting. *Fix direction:* make the completion UPDATE a compare-and-swap (`UPDATE ... SET status='completed' ... WHERE recording_id=? AND status='recording'`) and only `fireOnCompleteCallbacks` when affected-rows==1; and/or have the scan skip recording_ids currently present in `activeRecordings`. 2. **[LOW-MEDIUM] One-shot stop timer is not cancelled on the manual-stop path (check #3 gap).** `RecordingScheduler` cancels the per-recording timer on normal fire (`fireStopTimer` self-clears) and on the scan (`processCompletedRecordings`→`cancelStopTimer`), but the Recorder manual paths `stopRecording`/`cancelRecording` (Recorder.php:1185)/`deleteRecording` (Recorder.php:1209) have NO coupling to `RecordingScheduler::cancelStopTimer`. A recording stopped/cancelled/deleted before its effective end therefore leaves its one-shot timer armed for the full remaining duration, so `activeStopTimerCount()` does not return to baseline on manual stop (violates the check-#3 requirement). The late fire is itself harmless (`endRecording` status-guards the reconcile → returns false, no double onComplete), and this path is untested. *Fix direction:* register a Recorder `onComplete` callback (or an explicit stop hook) from the scheduler that calls `cancelStopTimer`, or route manual stops through the scheduler; add a test asserting the count returns to baseline after a manual stop. 3. **[LOW] Scan SQL does not clamp negative padding, diverging from `effectiveEndTime`'s `max(0,...)`.** `getRecordingsDueToStop` computes `end_time + COALESCE(post_padding_seconds, 60)` (Recorder.php:907) with no `GREATEST(0, …)`, whereas the timer path clamps via `effectiveEndTime` (`end_time + max(0, padding)`). For a NEGATIVE `post_padding_seconds` (not clamped at write time in `scheduleRecording`/ `SeriesRuleManager`) the scan would fire earlier than the timer. Not reachable with the default (60) or any non-negative value, so exposure is minimal. *Fix direction:* `end_time + GREATEST(0, COALESCE(post_padding_seconds, 60))` to mirror `effectiveEndTime`, or validate non-negative padding at write time. **Verdict: 3 FINDINGS** (1 MEDIUM, 1 LOW-MEDIUM, 1 LOW). Padding-default consistency (check #1) PASSED — not a finding. Loop to the Fixer for findings 1 & 2 (finding 3 is a low-risk hardening nit). ## Fixer (per-step) — SV-3.1c — 2026-07-12 Fixed ALL THREE review findings. Committed + pushed myself (§F). phpstan L9 0, Unit 4935/0, phpcs on touched files clean (2 pre-existing >120-char warnings on untouched Recorder lines 204/1654 only). ### Finding 1 — Double-completion race [MEDIUM] — belt AND suspenders **(a) Atomic completion CAS (the authoritative guard).** Both completion writes are now conditional + affected-rows-gated, using the SAME idiom as `ScanJobRepository::claimNext()` (the Workerman MySQL client returns the affected-row count for an UPDATE; verified via `PhlixMySQLConnection::query()` → `parent::query()`): - `Recorder::stopRecording()` (`src/LiveTv/Recorder.php`) — `UPDATE livetv_recordings SET status=... WHERE recording_id=? AND status=?` (bind prior status = `recording`); `fireOnCompleteCallbacks()` runs ONLY when `is_int($affected) && $affected >= 1`. On a lost race it logs debug + returns false (the process was still stopped; only the duplicate onComplete side effect is suppressed). - `Recorder::endRecording()` reconcile branch — same conditional CAS + affected-rows gate before `fireOnCompleteCallbacks()`. This makes concurrent completers (one-shot timer + scan tick interleaving at `terminateRecording`'s `Coroutine::sleep` yields) idempotent regardless of timing → exactly one onComplete + one status→ completed UPDATE. Matters once SV-3.1d wires comskip / media-item registration into onComplete. **(b) Scan exclusion (defense-in-depth).** `RecordingScheduler::processCompletedRecordings()` now `continue`s past any `recording_id` still present in `$this->stopTimerIds` (a live one-shot timer = the primary stop path). Chose the SCHEDULER's timer-set as the exclusion key rather than the Recorder's `activeRecordings` — **deliberately did NOT filter getRecordingsDueToStop() by activeRecordings**, because boot recovery (`resumeActiveRecordings`) re-attaches pid-alive recordings to `activeRecordings` WITHOUT re-arming a stop timer, so the scan is their ONLY stop path; excluding activeRecordings would strand them past their effective end. Also moved `RecordingScheduler::fireStopTimer()`'s `unset($stopTimerIds[$id])` into a `finally` AFTER `endRecording()` returns, so the id stays in the set throughout the (multi-second) ffmpeg teardown and a concurrent scan tick during that fire window still skips it. The CAS remains the ultimate guard for any residual window. ### Finding 2 — Stop-timer not cancelled on manual stop [LOW-MED] — callback hook, no ctor cycle Added an idempotent stop-hook mechanism to the Recorder: `onStop(callable)` + `private array $onStopCallbacks` + `fireOnStopCallbacks($recordingId)` (mirrors the existing onComplete plumbing but fires on ANY terminal transition, not just successful completion). Fired from all three manual paths — `stopRecording()` (always, before the CAS branch), `cancelRecording()` and `deleteRecording()` (via a `$wasActive` guard so it fires exactly once whether or not the row was live in memory). `RecordingScheduler.__construct()` registers the hook: `$this->recorder->onStop(fn($id) => $this->cancelStopTimer($id))`. **No ctor cycle / no DI-signature change** — the Recorder is built first and injected into the scheduler (existing `LiveTvServicesProvider` order); the hook is a runtime callback registration, not a constructor dependency. `cancelStopTimer` stays private (the closure binds `$this`). Therefore **no `public/index.php` / `start.php` mirroring needed** (neither entrypoint constructs the scheduler directly — DI does; §0.3 satisfied). `activeStopTimerCount()` now returns to baseline after a manual stop. ### Finding 3 — Negative-padding clamp [LOW] `Recorder::getRecordingsDueToStop()` scan SQL → `end_time + GREATEST(0, COALESCE(post_padding_seconds, 60))`, mirroring `effectiveEndTime()`'s `max(0, padding)` so a mis-stored negative padding cannot make the scan fire earlier than the timer path. ### Tests (built out around each fix) - `RecorderTimedStopTest::testCompletionIsIdempotentUnderTimerVsScanRace` (finding 1) — two `endRecording()` calls on the same still-`recording` orphan; DB mock returns affected-rows **1 then 0**; asserts onComplete fires EXACTLY once, first returns true / second false, both attempted the conditional UPDATE. No sleeps/timers — deterministic. - `RecorderTimedStopTest::testEndRecordingReconcilesOverdueRecordingToCompleted` (updated) — mock UPDATE now returns 1; added assertions that the completion UPDATE is a CAS (`status = ?` in SQL + prior `recording` status bound). - `RecorderTimedStopTest::testOnStopFiresOnManualStopPaths` (finding 2) — real Recorder; asserts onStop fires on live `stopRecording` (activeRecordings seeded via reflection, pid=0 → no real kill), `cancelRecording`, and `deleteRecording`. - `RecordingSchedulerTest::testScanSkipsRecordingsWithAnArmedStopTimer` (finding 1b) — arms a timer, then the scan reports the same id due-to-stop; asserts `endRecording` is NEVER called + the timer is left intact. - `RecordingSchedulerTest::testManualCancelCancelsArmedStopTimer` (finding 2) — REAL Recorder (only `startRecording` stubbed to avoid ffmpeg) so the onStop hook is genuinely wired; arm timer via `processDueRecordings`, then `cancelRecording` → `activeStopTimerCount()` back to 0. - `RecorderTimedStopTest::testGetRecordingsDueToStopAppliesPostPaddingInScan` (updated, finding 3) — scan-SQL assertion now expects `end_time + GREATEST(0, COALESCE(post_padding_seconds, 60))`. ### Verification (actual) - `./vendor/bin/phpstan analyse -c phpstan.neon.dist` → **[OK] No errors** (646 files). - `./vendor/bin/phpunit --testsuite Unit --no-coverage` → **Tests: 4935, 0 failures / 0 errors** (4 warnings / 8 skipped, all pre-existing in unrelated TranscodeManagerTest). `--filter 'RecorderTimedStop|RecordingScheduler|Recorder'` → 40 OK. - `./vendor/bin/phpcs --standard=PSR12` on the 4 touched files → 0 errors; only 2 pre-existing >120-char warnings on untouched Recorder lines 204 (comskip callback) / 1654 (docblock array shape). ### Files changed - `src/LiveTv/Recorder.php` — CAS on both completion UPDATEs; onStop hook infra + firing on stop/cancel/delete; scan-SQL `GREATEST(0, …)` clamp. - `src/LiveTv/Recording/RecordingScheduler.php` — scan skips ids with a live timer; onStop hook registered in ctor; `fireStopTimer` unset moved to `finally`. - `tests/Unit/LiveTv/RecorderTimedStopTest.php`, `tests/Unit/LiveTv/Recording/RecordingSchedulerTest.php`. ## Reviewer (re-review) — SV-3.1c fix — 2026-07-12 Re-reviewed the fix range `bcac8e50..a61f7782` (impl `ddd41106` + tests `a61f7782`) against the 3 original findings. Verified locally: phpstan L9 `-c phpstan.neon.dist` = [OK] 0 errors; `phpunit --filter 'RecorderTimedStop|RecordingScheduler|Recorder'` = OK (40 tests, 112 assertions); phpcs PSR-12 on both touched src files = 0 errors (2 pre-existing >120-char warnings on unchanged lines 204/1654, non-blocking §0.2). Check-by-check: 1. CAS RETURN-TYPE (highest priority) — CONFIRMED CORRECT. The parent Workerman client `Connection::query()` (vendor/workerman/mysql/src/Connection.php:1859-1860) returns `$this->sQuery->rowCount()` — an INT — for `update|delete|replace`; `PhlixMySQLConnection::query()` delegates to `parent::query()`. So `$affected` is a genuine int affected-row count and `is_int($affected) && $affected >= 1` is a valid gate. The normal (non-race) path matches the still-`recording` row and, because the UPDATE always changes `status`/`updated_at`, rowCount is 1 → onComplete fires exactly once (no MYSQL_ATTR_FOUND_ROWS "matched-but-unchanged 0" trap). The cited precedent `ScanJobRepository::claimNext()` (:158-166) relies on the identical `is_int(...) && < 1` idiom for a conditional UPDATE — the usage matches. NOT the feared regression. 2. IDEMPOTENCY (finding 1) — CONFIRMED. Both completion writes are conditional CAS (`WHERE recording_id=? AND status='recording'`): stopRecording (Recorder.php:802-828) fires onComplete only after the affected>=1 guard; endRecording's reconcile branch (:905-919) likewise; endRecording's live branch delegates to stopRecording (no separate write). No path fires onComplete unconditionally. Test `testCompletionIsIdempotentUnderTimerVsScanRace` (affected 1→0) proves exactly-once and would double-fire against pre-fix code. 3. SCAN EXCLUSION + SLOT TIMING (finding 1b) — CONFIRMED. processCompletedRecordings skips ids in `stopTimerIds` (RecordingScheduler.php:228); fireStopTimer clears the slot in `finally` AFTER endRecording returns (:336-345), so the id stays set through the ffmpeg-teardown window (terminateRecording precedes the CAS in stopRecording, so the id is present during the multi-second kill; cancelStopTimer only removes it after the row is already `completed`). Skipping by `stopTimerIds` (NOT `activeRecordings`) is correct: boot recovery (LiveTvManager::bootstrap→Recorder::resumeActiveRecordings) re-attaches pid-alive rows WITHOUT calling scheduleStopTimer, so recovered recordings are NOT in stopTimerIds and remain covered by the scan. No recording is left with neither a timer nor scan coverage. Test asserts endRecording is never called for an armed-timer row. 4. onStop EXACTLY-ONCE + NO CYCLE/RECURSION (finding 2) — CONFIRMED. onStop fires once per manual path via the `$wasActive` guard (stopRecording fires it; cancel/delete fire it only in the `!$wasActive` fallback). The scheduler ctor registers `onStop(fn=>cancelStopTimer)` on the already-built Recorder — the DI provider (LiveTvServicesProvider.php:205-219) builds Recorder→LiveTvManager→scheduler in order, no construction cycle; ctor signature unchanged; scheduler is only ever obtained via `container->get` (start.php:235) and is never `new`ed in index.php/start.php, so no entrypoint mirroring is owed. cancelStopTimer touches only Timer::del + the local array — it cannot re-enter the Recorder, so no recursion. activeStopTimerCount() returns to baseline on manual cancel (test `testManualCancelCancelsArmedStopTimer`). 5. PADDING CLAMP (finding 3) — CONFIRMED. Scan SQL `end_time + GREATEST(0, COALESCE(post_padding_seconds, 60))` (Recorder.php:977) mirrors effectiveEndTime()'s `$endTime + max(0, $postPaddingSeconds)` (:949); COALESCE default 60 matches the PHP default in endRecording. Timer and scan agree on the effective stop for the same row. 6. NO NEW REGRESSION — phpstan L9 clean; no exit/die/blocking-sleep introduced; onStop registered exactly once (single scheduler singleton) so onStopCallbacks is not an unbounded static; SV-3.1c timer/scan/padding behavior intact; Recorder↔Scheduler wiring sound. 7. TESTS GENUINE — the idempotency, onStop-on-all-manual-paths, and scan-skips-timer-held tests each fail against the pre-fix code (double onComplete, missing onStop mechanism, endRecording called by the scan respectively). They guard the exact seams. NO FINDINGS ## ⏸ PERF-4 PAUSE STATE (2026-07-12) — server resume point - **SV-4.7** ✅ done (prior). **SV-3.1 foundation (a+b0+e)** ✅ review NO FINDINGS. **SV-3.1c** (scheduler Timer + timed-stop@end+padding + padding fix) ✅ FULLY DONE: impl `50d3e992`/`89f3f35f`, fix `ddd41106`/`a61f7782` (3 review findings: double-completion race→atomic CAS + scan-skips-timer-held; stop-timer leak→onStop hook; negative-padding clamp), **re-review NO FINDINGS** `6f8749ee`. Unit 4935/0. - **SV-3.1d (media-item registration + `livetv_recordings.media_item_id` linkage migration)** — ✅ IMPL+TESTS DONE (pending review). Commits `c8845464` (impl+migration) + `0f20be7b` (tests), pushed; tree clean, local==origin. See "## Implementer — SV-3.1d" note below. Comskip STILL split out to SV-3.1d-comskip (deferred to SV-4.3) — NOT wired here. - **Server queue after SV-3.1d:** SV-4.3 (ComskipRunner non-blocking — audit+fix) → SV-3.1d-comskip (chapter markers → real media_item_id) → SV-3.1f (timeshift 501 stub @ `LiveTvStreamController.php:~129` → withFile/HLS + rolling buffer) → g (storage accounting) → h (LiveTvStreamController tests) → SV-3.6 (Trakt pull-sync) → SV-4.13-finish (remove `buildTranscodeCommandWithProfile` zero-callers + stale docrefs) → RE-AUDIT SV-0.6–0.9/1.x/2.2-2.3-2.7/3.3-3.4/4.1-4.6/4.8-4.12/4.14. - **NOTE:** external release-maintenance commits landed (Release v1.2.3, @phlix/ui v0.79→v0.80 bump, composer.lock) — HEAD `c9f1f26c`; all SV work preserved in ancestry. ## Implementer — SV-3.1d (media-item registration + linkage migration) — 2026-07-12 Registers a completed DVR recording's captured `.ts` as a playable `media_items` row on the once-only Recorder `onComplete` path and persists the resulting `media_items.id` back onto `livetv_recordings`. Comskip is NOT touched (that half is SV-3.1d-comskip, deferred to SV-4.3). Committed + pushed myself (`c8845464` impl+migration, `0f20be7b` tests). Tree clean, local==origin at `0f20be7b`. ### Migration - NEW `migrations/077_livetv_recording_media_item_link.sql` — `ALTER TABLE livetv_recordings ADD COLUMN media_item_id CHAR(36) NULL AFTER status` + `ADD INDEX idx_media_item_id`. Matches `media_items.id` (CHAR(36) UUID PK). One-ALTER-per-clause, NO `IF NOT EXISTS` (MySQL 8 rejects it on ADD COLUMN/INDEX; the runner downgrades duplicate 1060/1061 on replay — same idiom as 022). No migration-file test in the repo lists expected files (MigrationRunnerTest uses a tmp dir), so nothing to update. NOT run here (no DB) — runs on deploy. ### Registration (completion wiring) - NEW `src/LiveTv/Recording/RecordingMediaRegistrar.php` — `register(string $recordingId, string $recordingPath): ?string`. Wired via `$recorder->onComplete([$registrar, 'register'])` in `LiveTvServicesProvider`'s Recorder factory (NOT via `RecordingHooks::register`, which is comskip-specific — it takes a `ComskipPostProcessor`; media-item registration is a distinct concern, so inline registration is the correct fit). The Recorder fires `onComplete` EXACTLY once per completion (SV-3.1c atomic CAS), so registration runs once. - Guards (each returns null, inserts nothing): row not found; `status != 'completed'` (onComplete ALSO fires for rows `resumeActiveRecordings()` marks FAILED — those must never register); already-linked `media_item_id` (idempotent replay); missing / zero-length capture file (never register a broken item). - Insert delegated to the canonical **`ItemRepository::upsertByPath`** (path-deduped) — a retried completion returns the same id, no duplicate row. Columns populated: `library_id`, `name`=recording `title` (from the EPG/programme stored on the recording row), `type='video'` (valid `media_items.type` enum; the honest type for a raw capture — MediaItemShaper coerces unknown-to-it types to 'movie' for the API, harmless), `path`=the `.ts`, `metadata_json`={source:'livetv_dvr', recording_id, channel_id, program_id, description, recorded_start/end, duration_seconds}. `create()`'s only required keys are library_id/name/type/path; all other media_items columns default. - **Library association:** find-or-create a dedicated `video`-type library by name (config `dvr.library_name`, default 'DVR Recordings') via DIRECT SQL against `libraries` (NOT LibraryManager) — deliberately NO FolderWatcher, so the storage path is never scanned and cannot double-register the `.ts` files. INSERT mirrors `LibraryManager::createLibrary`'s columns exactly (id, name, type, paths, options). - **Linkage persisted:** `UPDATE livetv_recordings SET media_item_id = ?, updated_at = NOW() WHERE recording_id = ?` with the returned id — so SV-3.1d-comskip can attach chapter markers to the real item. - **Reads use the plain-array media-layer convention** (like ItemRepository / LibraryManager), NOT the LiveTv `RowQuery` cursor — see the risk note below. ### Config + DI (no ctor/DI-signature change → no entrypoint mirror) - `config/livetv.php` — NEW `dvr.library_name` (default 'DVR Recordings'). - `LiveTvServicesProvider` — registers `RecordingMediaRegistrar` as a per-worker singleton (resolving `ItemRepository` from the container) and calls `$recorder->onComplete(...)` in the Recorder factory. NO existing ctor/DI signature changed → NO `public/index.php` / `start.php` mirror needed (both entrypoints share this container; the wiring is a runtime callback registration). ### Tests - NEW `tests/Unit/LiveTv/Recording/RecordingMediaRegistrarTest.php` (7): completed recording → asserts upsertByPath data (library_id/name/type='video'/path/metadata incl. duration_seconds) + the `UPDATE ... media_item_id` params `['media-1','rec-1']`; missing file / zero-length file / status='failed' / already-linked / missing row all assert `upsertByPath` is NEVER called; library find-or-create asserts a `libraries` INSERT with the configured name + 'video' type and that the media item uses that exact new library id. - `tests/Unit/Common/Container/Providers/LiveTvServicesProviderTest.php` (+1, updated): Recorder now carries EXACTLY 2 onComplete hooks (comskip + registrar); `RecordingMediaRegistrar` resolves as a shared singleton (added an `ItemRepository` mock to the test container so the registrar factory resolves). ### Verification (actual, this box) - `./vendor/bin/phpstan analyse -c phpstan.neon.dist` → **[OK] No errors** (647 files). - `./vendor/bin/phpunit --testsuite Unit --no-coverage` → **Tests: 4943, 0 failures / 0 errors** (4 warnings / 8 skipped — all pre-existing in TranscodeManagerTest, unchanged from the SV-3.1c 4935 baseline; +8 = my new tests). `--filter 'RecordingMediaRegistrar|LiveTvServicesProvider'` → 10 OK / 44 assertions. - `./vendor/bin/phpcs --standard=PSR12` on the 4 touched files → **0 errors**. ### Seams left for later (NOT done here) - **SV-3.1d-comskip** (deferred, gated on SV-4.3): attach comskip EDL→chapter markers to the real `media_item_id`. The `media_item_id` is now produced + persisted, so that step has a real item to attach to. `RecordingHooks::register` still has no caller (it wires a `ComskipPostProcessor`) — leave it for that step. - **RISK / on-box verify owed (pre-existing, NOT SV-3.1d scope):** the LiveTv read path (`Recorder`/`RecordingScheduler` via `RowQuery`/`ResultSet`) narrows on `$result instanceof \Phlix\LiveTv\Dto\ResultSet`, but production `PhlixMySQLConnection::query("SELECT …")` returns a PLAIN ARRAY (`parent::query` → `PDOStatement::fetchAll`, verified) — nothing in `src/` ever produces a `ResultSet`. So `RowQuery::rows/firstRow` appear to yield `[]`/`null` for real results, which would mean `Recorder::getRecording()`/`stopRecording()` (hence the whole DVR completion → my `onComplete` hook) may not fire against a live DB. This is the DVR stack's already-OWED on-box verification (SV-3.1 foundation/c notes), a PRE-EXISTING concern I did NOT fix (out of SV-3.1d scope). My registrar itself uses the plain-array media-layer convention that provably works in prod, so its own logic is correct regardless; but end-to-end firing depends on that owed verify. A future step should either confirm the connection returns ResultSet-shaped objects in prod or fix `RowQuery` to accept plain arrays. - **On-box verify OWED for SV-3.1d itself** (migration + start.php outside CI): after deploy, run `php scripts/run-migrations.php` (adds `media_item_id`), complete a recording, confirm a `media_items` row exists for the `.ts` and `livetv_recordings.media_item_id` is set; confirm a zero-length/failed capture leaves `media_item_id` NULL. ## Reviewer (per-step) — SV-3.1d — 2026-07-12 Reviewed `git diff 34bd569b..5f9c8857` = `c8845464` (impl + migration 077) + `0f20be7b` (tests). Read the step's plan entry, the SV-3.1d implementer note, RowQuery/ResultSet, PhlixMySQLConnection + parent `Workerman\MySQL\Connection::query()`, Recorder completion chain, ItemRepository working-idiom, migration 077 + 022, config/livetv.php, LiveTvServicesProvider, and both entrypoints. Read-only gates (this box): `phpunit --filter 'RecordingMediaRegistrar|LiveTvServicesProvider'` = **OK (10 tests, 44 assertions)**; `phpstan analyse -c phpstan.neon.dist` on the touched files = **[OK] No errors**. The SV-3.1d registration DIFF itself is correct — CHECKS #2–#6 pass (see below). The one blocking issue is CHECK #1, the RowQuery/ResultSet landmine, which is **PRE-EXISTING** (not introduced by SV-3.1d) but renders the whole DVR read path — and therefore the SV-3.1d `onComplete` hook — inert in production. ### Findings 1. **[BLOCKING — PRE-EXISTING, NOT an SV-3.1d change] The LiveTv `RowQuery` read path yields EMPTY against the production DB, so the entire DVR read path (and hence the SV-3.1d `onComplete` registrar) never fires against a live database.** - `src/LiveTv/Dto/RowQuery.php:45,65,82` — `rows()/firstRow()/hasRows()` all narrow on `if (!$result instanceof \Phlix\LiveTv\Dto\ResultSet) { return [] / null / false; }`. - `ResultSet` (`src/LiveTv/Dto/ResultSet.php:34`) is an **abstract** class with a `num_rows` property + `fetch()` method. The ONLY things that `extends ResultSet` are the 6 LiveTv unit-test mock files; `grep -rn "ResultSet" src/` finds nothing in `src/` that ever constructs or returns one. - Production shape: `PhlixMySQLConnection::query()` (`src/Common/Database/PhlixMySQLConnection.php:258`) delegates to `parent::query()`, and `Workerman\MySQL\Connection::query()` (`vendor/workerman/mysql/src/Connection.php:1857-1858`) for a SELECT returns `$this->sQuery->fetchAll($fetchmode)` — a **plain `array>`**, never a `ResultSet` object. `Connection::class` is bound to the real `PhlixMySQLConnection` via `CoreServicesProvider.php:81` → `ConnectionPool::getConnection('mysql')`. - Net effect in prod: for every real SELECT, `$result instanceof ResultSet` is false, so `RowQuery::firstRow()` → `null`, `rows()` → `[]`, `hasRows()` → `false`. This poisons `Recorder::getRecording()` (`Recorder.php:359`), `getAllRecordings()`, `getRecordingsDueToStop()` (`:967`, the SV-3.1c timed-stop scan), `resumeActiveRecordings()` (SV-3.1e boot recovery), `RecordingScheduler::processDueRecordings` (`RecordingScheduler.php:133`), plus GuideManager/SeriesRuleManager/RecordingDeduplicator. - Failure scenario for THIS step: `Recorder::stopRecording()` (`:774-777`) and `endRecording()` (`:866`) both do `$recording = $this->getRecording(...); if (!$recording) return false;` BEFORE the atomic completion CAS + `fireOnCompleteCallbacks()` (`:828`/`:919`). In prod `getRecording()` is always `null`, so completion short-circuits and the SV-3.1d `onComplete` registrar is NEVER invoked. Green unit tests hide this exactly because the Recorder tests inject `ResultSet`-shaped mocks while production returns plain arrays — the "green tests masking inert prod code" failure mode. - Provenance: RowQuery/ResultSet are `@since Wave 5a (post-O.7)` — they predate SV-3.1. This is a PRE-EXISTING defect surfaced (and correctly flagged) by the SV-3.1d implementer, NOT a regression in `c8845464`/`0f20be7b`. The SV-3.1d registrar itself is correct: it reads via the plain-array media-layer convention (`RecordingMediaRegistrar::fetchRecording` at `:215-232`, `is_array($result[0])`), which is the idiom that provably works in prod (same as `ItemRepository::findByPath`/`firstRow`). - Fix direction (its OWN sub-step, regardless of which sub-step is credited): make `RowQuery::rows/firstRow/hasRows` accept the plain-array shape `query()` actually returns (iterate `array>` and drop the `instanceof ResultSet` narrowing — keeping a fallback for the mock shape if desired), OR route all LiveTv reads through the same plain-array idiom the working repositories use. Then re-point the LiveTv unit-test mocks off `ResultSet` onto plain arrays so the tests exercise the real prod shape. This is the already-OWED on-box DVR verification made concrete: without it, SV-3.1 a/b0/c/d/e are all inert in production despite green mock-DB tests. 2. **[LOW — non-blocking; dominated by finding #1] `RecordingMediaRegistrar::ensureRecordingsLibrary` can create duplicate "DVR Recordings" libraries under a concurrent first-completion race.** - `src/LiveTv/Recording/RecordingMediaRegistrar.php:249-281` does a `SELECT id FROM libraries WHERE type=? AND name=? LIMIT 1` then, on miss, `INSERT INTO libraries ...`. `libraries` has no unique constraint on `(type, name)` (migration 001), and the registrar is a per-worker singleton, so two DIFFERENT recordings completing concurrently (e.g. a manual stop on an HTTP worker + the worker-0 scheduler, or two coroutines on worker 0) before the library first exists can each miss the SELECT and both INSERT → 2+ duplicate DVR libraries. Subsequent completions reuse whichever `LIMIT 1` returns. - Failure scenario: cosmetic split of DVR recordings across duplicate libraries on a fresh install; self-limiting (happens once, early). Benign TODAY because finding #1 makes the whole completion path inert, but it becomes real once #1 is fixed. - Fix direction (fold into the #1 fix or a follow-up): add a UNIQUE index on `libraries(type, name)` (or re-SELECT after a failed INSERT, mirroring `ItemRepository::upsertByPath`'s race-collision reuse), so find-or-create is idempotent. ### CHECKS #2–#6 — SV-3.1d registration diff: CLEAN - **#2 Registration correctness:** all four guards short-circuit BEFORE `upsertByPath` (`register()` `:126` row-not-found → null; `:136-138` `status != 'completed'` → null, so a FAILED row from `resumeActiveRecordings()` never registers; `:142-145` already-linked → returns existing id, no insert; `:149-155` missing/zero-length file → null). onComplete is registered exactly once: PHP-DI shares the `Recorder::class` factory (`LiveTvServicesProvider.php:186`) as a singleton, and `$recorder->onComplete([$registrar,'register'])` runs once in that factory (Recorder carries exactly 2 hooks: comskip + registrar, asserted by the provider test). - **#3 Insert correctness:** `ItemRepository::upsertByPath` (path-deduped, returns non-null `string`) is used with `library_id / name (EPG title) / type='video' / path=.ts / metadata_json`. The returned id is captured and persisted by the parameterized, colon-free `UPDATE livetv_recordings SET media_item_id = ?, updated_at = NOW() WHERE recording_id = ?` (`:192-195`) — no injection. All read columns exist in the `livetv_recordings` schema (012a + 022 + 077). - **#4 Library find-or-create:** direct parameterized/colon-free SQL against `libraries`, deliberately NOT via LibraryManager/FolderWatcher (so the storage path is never scanned/ double-registered); INSERT columns mirror `createLibrary`. (Race caveat = finding #2.) - **#5 Migration 077:** MySQL-8 compatible — no `IF NOT EXISTS`, one ALTER per clause, `media_item_id CHAR(36) NULL` matches `media_items.id`; replay-safety relies on the runner downgrading 1060/1061, confirmed the real idiom (`MigrationRunner::isAlreadyAppliedNote` matches "Duplicate column name"/"Duplicate key name") and identical to migration 022's `pid` ALTER pair. - **#6 Scope/policy:** no comskip wiring (correctly deferred to SV-3.1d-comskip/SV-4.3; `media_item_id` is produced + persisted for it); no ctor/DI-signature change — both `public/index.php:72` and `start.php` build the container via `ContainerFactory::create`, which registers `LiveTvServicesProvider` (`ContainerFactory.php:131`), so no entrypoint mirror is needed; nothing stubbed/deleted; tests are genuine (each rejection path asserts `upsertByPath` is NEVER called; the happy path asserts the insert fields + the exact `['media-1','rec-1']` linkage UPDATE params; the library test asserts the INSERT name + 'video' type + that the item uses the new library id; test mocks return PLAIN ARRAYS, matching the real prod shape). **Verdict:** 2 findings. #1 is BLOCKING for the SV-3.1 DVR stack as a whole but is PRE-EXISTING (RowQuery/ResultSet, `@since Wave 5a`) and out of SV-3.1d's own scope — the SV-3.1d registration diff (`c8845464`/`0f20be7b`) is itself correct and complete. The RowQuery fix must be its own sub-step (it also fixes SV-3.1 a/b0/c/e inertness); finding #2 (LOW) should fold into that fix. ## Implementer — SV-3.1-rowquery (DVR read-path resurrection) — 2026-07-12 Fixed the CONFIRMED BLOCKING landmine (finding #1) + folded in the LOW library-race (finding #2). Committed + pushed myself; tree clean, local==origin. **Part A — RowQuery consumes the plain-array shape production actually returns.** `src/LiveTv/Dto/RowQuery.php` — `rows()/firstRow()/hasRows()` no longer narrow ONLY on `instanceof ResultSet`. Each now handles BOTH shapes: - **Plain array (prod shape)** — `PhlixMySQLConnection::query("SELECT …")` → Workerman `Connection::query()` → `fetchAll()` returns `array>`. `rows()` → new private `rowsFromArray()` returns the list (filtering non-array elements for L9-safe typing); `firstRow()` → `$result[0]` when it is an array, else null; `hasRows()` → `$result !== []`. An empty SELECT (`[]`) → `[]`/null/false (correct). - **ResultSet cursor (test-mock shape)** — the original `num_rows`/`fetch()` path is KEPT verbatim, so all 6 existing LiveTv `ResultSet`-mock tests still pass. `ResultSet` is NOT deleted (per §0.1). Any non-array / non-ResultSet (null, scalar, INSERT/UPDATE int) → no rows, unchanged. Net: against a plain-array `query()` result, `Recorder::getRecording()` returns a real row, `getRecordingsDueToStop()`/`resumeActiveRecordings()` return real rows, and the SV-3.1d `onComplete` registrar can finally fire. This resurrects the whole DVR read path (SV-3.1 a/b0/c/d/e) that was silently inert vs a live DB. **REGRESSION GUARDS (the key deliverable) — drive the read path with the PROD plain-array shape:** - `tests/Unit/LiveTv/Dto/RowQueryTest.php` (+4) — `rows`/`firstRow`/`hasRows` fed plain arrays directly (prod shape) + empty-result null. - `tests/Unit/LiveTv/RecorderPlainArrayReadPathTest.php` (NEW, 4) — a mocked `Connection::query()` returns PLAIN ARRAYS (not a ResultSet); asserts `getRecording()`→real row, empty→null, `getRecordingsDueToStop()`→`['rec-1','rec-2']`, `resumeActiveRecordings()`→reads the interrupted row, reconciles to FAILED, fires onComplete. - PROOF they guard the landmine: with the src fixes stashed to HEAD (pre-fix `instanceof ResultSet`-only RowQuery), these fail — plain-array `rows`→size 0, `firstRow`→null, `hasRows`→false, `getRecording`→null, `getRecordingsDueToStop`→`[]` (7 failures + 1 error). With the fix: green. **Part B — DVR library find-or-create race (finding #2).** `src/LiveTv/Recording/RecordingMediaRegistrar.php::ensureRecordingsLibrary` — chose the **migration-free re-SELECT convergence** (NOT a global UNIQUE(type,name) index — that could conflict with legitimate pre-existing duplicate library names on a live box, unverifiable here; §0.3-safe). New private `findRecordingsLibraryId()` selects with a DETERMINISTIC `ORDER BY created_at ASC, id ASC LIMIT 1` (not a bare `LIMIT 1`, whose row order is undefined). Flow: find → if absent, INSERT (wrapped in try/catch so a future dup-key can't propagate) → **re-SELECT the canonical id**. Under a concurrent double-INSERT every caller converges on the SAME single library (earliest-created, id-tiebreak), so recordings never split across duplicate DVR libraries; the method returns the one canonical id under concurrency. Forward-compatible: if a UNIQUE(type,name) index is ever added, the dup-key INSERT is swallowed and reconciled. Tests: `RecordingMediaRegistrarTest` `testConcurrentLibraryCreateConvergesOnCanonicalId` (racing re-SELECT returns a different 'lib-canonical' → item registered there, deterministic ORDER BY asserted) + `testDuplicateKeyOnLibraryInsertReconcilesToCanonicalId` (INSERT throws → reconciled). **ResultSet status:** still referenced by RowQuery (both-shape support) AND by the 6 LiveTv ResultSet-mock test files, so it is NOT fully unused — do NOT delete. Left in place per §0.1; no §6 removal-queue entry needed yet. **Verification:** phpstan L9 `-c phpstan.neon.dist` = **[OK] No errors** (647/647). phpcs PSR-12 on `RowQuery.php` + `RecordingMediaRegistrar.php` = **0 errors**. `phpunit --testsuite Unit` = **OK, 4953 tests, 38653 assertions, 5 skipped, 0 failures** (baseline ~4943 + 10 new). `--filter 'RowQuery|Recorder|RecordingScheduler|RecordingMediaRegistrar'` = 63/63 green. **On-box verify STILL OWED:** this makes the read path correct vs the prod plain-array shape and unit-guards it, but a live end-to-end DVR record→complete→playable check on the box (SELECT returns real rows → onComplete registrar inserts the media_item + persists the linkage → item playable) remains the final proof. ## Reviewer (per-step) — SV-3.1-rowquery — 2026-07-12 Reviewed `git diff eee0a33a..c63e7882` = `9b32e278` (Part A: RowQuery fix + tests) + `c63e7882` (Part B: library race + tests). Read-only gates this box: `phpstan analyse -c phpstan.neon.dist` = **[OK] No errors** (647/647); `phpunit --filter 'RowQuery|Recorder|RecordingScheduler|RecordingMediaRegistrar'` = **63/63 green**; full `--testsuite Unit --no-coverage` = **4953 tests, 0 failures/errors** (4 pre-existing warnings + 5 skips — TranscodeManagerTest, not this diff). Scope confirmed: only `RowQuery.php` + `RecordingMediaRegistrar.php` + the 3 test files touched; `ResultSet.php` left in place (§0.1); no ctor/DI-signature change. **1. Landmine genuinely closed (CONFIRMED).** `RowQuery::rows/firstRow/hasRows` (`src/LiveTv/Dto/RowQuery.php:50-116`) now branch on `is_array($result)` FIRST: `rows()` → `rowsFromArray()` (filters non-array elements, L9-safe, returns the row list); `firstRow()` → `$result[0]` when array else null (empty `[]` → `$result[0] ?? null` → null); `hasRows()` → `$result !== []`. The `ResultSet` cursor path (lines 58-66/88-97/111-115) is preserved VERBATIM below each new branch, so the 6 existing mock tests still pass. Against the prod plain-array shape `PhlixMySQLConnection::query()` returns, `Recorder::getRecording()` (`:359`), `getRecordingsDueToStop()` (`:983`) and `resumeActiveRecordings()` now return real rows. Typing is L9-clean (no mixed-narrowing errors; phpstan 0). **2. Sibling-landmine sweep — RowQuery is the ONLY inert chokepoint (CONFIRMED).** `grep instanceof.*ResultSet` + `->num_rows`/`->fetch()` across `src/` finds cursor-narrowing ONLY inside `RowQuery.php` (the preserved mock path). The other LiveTv reads already used the correct prod plain-array idiom and were NOT inert: `ChannelManager` reads via `RowMap::listFromMixed()` (`src/Common/Util/RowMap.php:61` — `is_array` + iterate, correct); `LiveTvManager::buildStreamUrlForChannel` (`:724-732`), `ComskipIntegration::getRecordingRow` (`:262-273`) and `ComskipLifecycleManager::getRecordingData` (`:259-275`) all guard with `is_array($result) && !empty($result)` + `is_array($result[0])`. `RowQuery` is used ONLY in `src/LiveTv/` (LiveTv-only; zero references elsewhere in `src/`), and `src/LiveTv/Epg/` issues no direct `db->query`. No sibling requires the same fix. **3. Regression tests genuine (CONFIRMED, not tautological).** `RowQueryTest` (+4) feeds plain arrays directly and asserts count/first/has. `RecorderPlainArrayReadPathTest` (NEW, 4) drives a mocked `Connection::query()` returning PLAIN ARRAYS (not a ResultSet) through the real `Recorder` and asserts `getRecording()`→real row, empty→null, `getRecordingsDueToStop()`→`['rec-1','rec-2']`, `resumeActiveRecordings()`→reconciles the interrupted row to FAILED and fires onComplete. The pre-fix diff shows `rows/firstRow/hasRows` had ONLY the `instanceof ResultSet` branch, so a plain array returned `[]`/null/false — these assertions provably FAIL pre-fix (the claimed 7 failures + 1 error), pass post-fix. **4. Part B — library race (CONFIRMED correct).** `findRecordingsLibraryId()` (`:318-333`) selects `ORDER BY created_at ASC, id ASC LIMIT 1` (deterministic, not bare LIMIT 1); `libraries` genuinely has `created_at` (migration 001:35) and `type='video'` is a valid ENUM value. `ensureRecordingsLibrary()` (`:250-304`) does find → INSERT-in-try/catch → re-SELECT the canonical id. Under a concurrent double-INSERT every caller re-SELECTs the SAME earliest-created/id-tiebroken row, so items always register under one canonical library — no split. Parameterized + colon-free (no injection). Migration-free re-SELECT chosen over a UNIQUE(type,name) index deliberately (would conflict with legit pre-existing dup names, unverifiable here; §0.3-safe) and is forward-compatible with such an index. Tests `testConcurrentLibraryCreateConvergesOnCanonicalId` (asserts the item uses 'lib-canonical', not the just-inserted id, and asserts the ORDER BY) + `testDuplicateKeyOnLibraryInsertReconcilesToCanonicalId` (INSERT throws → swallowed → reconciled) guard both paths. **5. No regression / scope (CONFIRMED).** phpstan L9 [OK] 0; Unit 4953/0 (baseline ~4943 + 10 new); `ResultSet` retained; no entrypoint/DI mirror needed. **6. Build-out completeness (CONFIRMED at code level).** SELECT → RowQuery now yields real rows → `Recorder::stopRecording()`/`endRecording()`'s `getRecording()` gate passes → atomic CAS + `fireOnCompleteCallbacks()` runs → the SV-3.1d `RecordingMediaRegistrar::register` onComplete hook fires → reads the recording (plain-array idiom) → `ensureRecordingsLibrary` → `upsertByPath` → linkage UPDATE. The DVR read path is code-sound end-to-end. The on-box live record→complete→playable verification remains OWED (as the implementer noted) but the CODE path is now correct against the prod shape. **Verdict: NO FINDINGS.** ## Orchestrator — SV-4.1–4.6 RE-AUDIT roll-up (2026-07-12, perf-4) Real opencode commits (worklog :91-96 hashes are WRONG/nonexistent): SV-4.1=`e263be5b`, SV-4.2–4.5=`197fb948` (one commit), SV-4.6=`a2853ff2`. - **SV-4.1 [S-F13] segment-cap → DONE (confirmed).** Reservation `segmentEncodesInFlight[$final]` set BEFORE the yieldable glob (`TranscodeManager.php:772` precedes `:786`), rollback+`SegmentBusyException` on over-cap; `finally` releases only launched. Behavioral cap/dedup tests present. No action. - **SV-4.2 [S-F23] ffmpeg cancel/timeout → PARTIAL.** `timeout ` wrapper on `buildDetachedCommand` (whole-file/CMAF) + `Recorder::terminateRecording` SIGTERM→SIGKILL DONE. GAPS: (1) the on-demand PER-SEGMENT encode path (`launchDetachedSegment` `FfmpegRunner.php:1981-1996`) has NO `timeout`, no PID tracking — the exact scrub-storm orphan; (2) no client-disconnect→kill (only `posix_kill($pid,0)` liveness probe); (3) server `RelayConsumer::onHttpCancel` (`:1442-1458`) closes local conn + discards accumulator but does NOT kill the ffmpeg PID (the X1/HB-4.9 server half). → Complete (cross-repo X1). - **SV-4.3 [S-F11] ComskipRunner non-blocking → DONE ⭐ (confirmed).** `stream_set_blocking(false)` both pipes + `stream_select`-poll with per-iteration hrtime timeout vs 300s → `proc_terminate(SIGKILL)`; output bounded. Old blocking bug gone; timeout reachable. **SAFE TO WIRE COMSKIP (SV-3.1d-comskip).** (Recommend adding a wedged-process timeout test when wiring.) No fix needed. - **SV-4.4 [S-F10] webhook backoff → PARTIAL (inert).** `WebhookDispatcher::dispatchAsync`+backoff+one-shot timer are correct but have ZERO callers (dead); no `CURLOPT_CONNECTTIMEOUT` in `WebhookHttpClient`; the live event→webhook path is a DIFFERENT class `WebhookService::dispatchEvent`/`handleFailedDelivery` (already has DB retry + one-shot timer + async client). → Complete (reconcile: add connect-timeout to WebhookHttpClient; wire or remove dead dispatchAsync per §0.1/§6). - **SV-4.5 [S-F15/F16] Roku/HdHomeRun/MusicBrainz async → NOT-DONE.** Commit `197fb948` claimed "MusicBrainz async" but touched none of the targets. Still blocking: `RemoteRokuClient.php:158-172` (usleep+`file_get_contents`), `RokuEcpClient.php:125`/`HdHomeRunTunerDriver.php:129` (usleep), `MusicMetadataProviderTrait.php:45` per-INSTANCE limiter (not static-per-host, not coroutine-aware). → Complete (whole step). - **SV-4.6 [S-F20] `original` copy variant → DONE (confirmed).** `array_filter(!isCopy)` excludes the `id:'original'` `isCopy:true` passthrough from `buildMultiVariantMaster` (all-copy fallback kept); transcoded "Original" (`isCopy:false`, real IDR) stays switchable. Behavioral tests present. No action. Server Complete queue: SV-3.1d-comskip (NOW unblocked by SV-4.3) → SV-4.2 (scrub-storm, X1) → SV-4.5 (blocking I/O) → SV-4.4 (webhook reconcile). Then SV-3.1 f/g/h, SV-3.6, SV-4.13-finish, remaining re-audits (SV-4.8–4.12/4.14, SV-0.6–0.9, SV-1.x, SV-2.2/2.3/2.7, SV-3.3/3.4). ## Implementer — SV-3.1d-comskip (comskip → chapter markers on real media_item_id, off the hot path) — 2026-07-12 Wired comskip commercial-detection into the DVR completion path so a completed recording's EDL is parsed into chapter markers attached to the REAL `media_item_id` (produced by SV-3.1d's `RecordingMediaRegistrar`), run OFF the worker-0 completion coroutine. **Chose the "wire ComskipLifecycleManager directly" option** (the existing wired onComplete comskip handler) — NOT RecordingHooks — so no parallel comskip system was built. `RecordingHooks::register` / `ComskipPostProcessor` / `MarkerService` remain in place, still without a caller (alternative path not taken; kept per §0.1). ### The completion → comskip → markers flow - Recorder fires onComplete (once, SV-3.1c atomic CAS) with `(recordingId, filePath)`. Hook order in `LiveTvServicesProvider`: **#1** `ComskipLifecycleManager::enqueue` (auto-wired in the Recorder ctor), **#2** `RecordingMediaRegistrar::register` (sets `livetv_recordings.media_item_id`). - **#1 enqueue now only QUEUES + schedules an off-hot-path drain** (see below) — it no longer runs comskip inline. So the completion coroutine returns immediately. - The deferred drain (a one-shot Workerman timer, ~1s later) fires AFTER the whole completion coroutine — so #2 has committed `media_item_id`. It runs `ComskipIntegration::processRecording`, which now: resolves the recording's `media_item_id`, runs comskip (existing SV-4.3 `ComskipRunner`), parses the EDL (`ComskipEdlParser`), stores the recording-row commercial stats (unchanged), AND attaches the parsed segments as chapter markers on the real media item via `ChapterMarkerService::persistChapters(media_item_id, chapters)` → `media_items.metadata_json.commercial_chapters`. ### Off-hot-path mechanism (why it can't stall the worker) `ComskipLifecycleManager::enqueue` → `scheduleDrain()`: when a Workerman worker is RUNNING (`WorkerContext::isEventLoopRunning()`), it arms a ONE-SHOT `Workerman\Timer::add(1s, …, [], false)` (guarded by a `drainScheduled` flag; new enqueues while one is armed just append to the queue the pending drain will pick up) and RETURNS — the completion coroutine is never held for the comskip duration (up to 300s). The drain runs in the timer's own coroutine (Swoole adapter wraps timer callbacks in `Coroutine::create()`), serialized (`drainQueue()` = `while (processNext())`, one recording at a time). Verified the hook mask (`SwooleRuntime::SAFE_HOOK_NAMES`): `SWOOLE_HOOK_PROC` + the blocking-function hook are EXCLUDED (so a raw inline comskip poll could stall the loop) but `SWOOLE_HOOK_STREAM_FUNCTION` (which covers `stream_select`) IS enabled — so the existing SV-4.3 `ComskipRunner` poll loop cooperatively yields (hooked `stream_select` + `Coroutine::sleep`) and does not freeze the worker. Deferring the run off the completion coroutine + the cooperative runner = the completion path is never blocked. Outside a running worker (CLI/PHPUnit/FPM — where `Workerman\Timer` is unusable and there is no loop to protect) `scheduleDrain()` drains synchronously (historic behaviour; `Timer::add` outside a live worker throws "Timer can only be used in workerman running environment" — the reason the gate is `isEventLoopRunning()`, not merely `class_exists(Timer)`). ### Idempotency / guards / failure-safety - `ComskipIntegration::processRecording` (when wired with `ChapterMarkerService`) SKIPS the comskip run entirely if the recording has NO `media_item_id` (nothing to attach to — e.g. a failed/empty capture the registrar never registered); a missing `.ts` throws (caught upstream). "Only run for a completed recording WITH a media_item_id and a present .ts" ✔. - `ComskipLifecycleManager::isAlreadyProcessed` (`commercial_processed_at`) guards re-enqueue; `persistChapters` overwrites `commercial_chapters` (idempotent) — no double markers on reprocess. - comskip failure/timeout/unavailable → `processRecording` throws → `processRecordingSync` catches + logs, never rethrows → drain continues, recording stays playable (media item already registered, just without markers). No exception escapes the completion path. ### Files changed - `src/LiveTv/ComskipRunner.php` — optional 3rd ctor param `?int $timeoutSeconds` (default = 300 const); makes the wedged-process timeout testable without a 300s wait. No behavior change at default. - `src/LiveTv/Recording/ComskipIntegration.php` — optional 5th ctor param `?ChapterMarkerService`; `processRecording` resolves `media_item_id` (new `resolveMediaItemId`), skips when unlinked, and attaches chapter markers after the run. When constructed WITHOUT a chapterService (legacy/tests) behaviour is unchanged (no extra queries, no marker attach). - `src/LiveTv/Recording/ComskipLifecycleManager.php` — `enqueue` defers via `scheduleDrain()`; new `shouldDeferDrain()`/`armDrainTimer()` (overridable test seams), `onDrainTimer()`, public `drainQueue()`; `drainScheduled` flag + `DRAIN_DELAY_SECONDS`. - `src/Common/Container/Providers/LiveTvServicesProvider.php` — registers `ChapterMarkerService` (from `ItemRepository`) and injects it into `ComskipIntegration`. **No ctor/DI-signature change to Recorder or either entrypoint** — the new params are optional and wired only through this shared provider (both `public/index.php` + `start.php` resolve it), so no dual-entrypoint mirror is needed. ### Tests added (mock the comskip subprocess like ComskipRunnerTest) - `ComskipRunnerTest::testRunTimesOutAndKillsWedgedProcess` — fake comskip that `sleep 30`s with a 1s timeout override → `RuntimeException "Comskip timed out after 1 seconds"` in <10s (SIGKILL reachable; SV-4.3 audit's recommended wedged test). - `ComskipIntegrationTest::testProcessRecordingAttachesChaptersToLinkedMediaItem` (media_item_id 'media-1' → `persistChapters('media-1', chapters)` called), `::testProcessRecordingSkipsWhenNoLinkedMediaItem` (media_item_id null → comskip `run` NEVER called, no persist, empty result). - `ComskipLifecycleManagerTest::testComskipFailureDoesNotEscapeEnqueue` (processing throws → enqueue does NOT throw, runningCount released), `::testEnqueueDefersToTimerAndDoesNotProcessInline` (deferred: queued + timer armed, NOT processed inline; manual drain processes once), `::testDeferredTimerFiringDrainsQueue` (timer fire → drains → processed once). Deferral tested via an inline anon subclass overriding the seams (a real running worker can't be spun in a unit test). ### Verification (this box) - `phpstan analyse -c phpstan.neon.dist` → **[OK] No errors** (647). - `phpunit --testsuite Unit --no-coverage` → **4959 tests, 0 failures/errors** (5 pre-existing skips; baseline 4953 + 6 new). `--filter 'Comskip|ChapterMarker|LiveTvServicesProvider|RecordingMediaRegistrar'` → 70 OK. - `phpcs --standard=PSR12` on the 4 touched src files + 3 touched test files → **0 errors**. ### On-box verify OWED (start.php / Timer / real comskip outside CI) Deploy, complete a real recording that registered a media item, confirm within ~1s the drain timer fires and (with comskip installed) `media_items.metadata_json. commercial_chapters` is populated for the recording's `media_item_id`, the `livetv_recordings.commercial_*` stats are written, and a recording with no `media_item_id` / no comskip binary leaves the item playable with no markers and no worker stall. ## Reviewer (per-step) — SV-3.1d-comskip — 2026-07-12 Reviewed impl commit `5700403e` + tests commit `d18a8fe8` at HEAD. Verified: phpstan `-c phpstan.neon.dist` on the 5 touched src files = No errors; `phpunit --filter 'Comskip|ChapterMarker|LiveTvServicesProvider|RecordingMediaRegistrar'` = 70/70 OK. Off-the-hot-path claim CONFIRMED: `ComskipLifecycleManager::enqueue` → `scheduleDrain()` arms a genuine ONE-SHOT `Workerman\Timer::add(1.0, …, [], false)` (fourth arg `false`) under a `drainScheduled` re-entrancy guard and returns immediately; the completion coroutine is never held for the comskip duration. Hook ordering CONFIRMED: enqueue is Recorder-ctor hook #1 (arms timer, returns), `RecordingMediaRegistrar::register` is onComplete hook #2 (sets `media_item_id` synchronously in the same `fireOnCompleteCallbacks` loop); the 1s timer fires strictly after both. Skip-when-unlinked, failure-swallowed (`processRecordingSync` catch, never rethrows), idempotent markers (`persistChapters` overwrites), and the `commercial_processed_at` re-enqueue guard all verified. DB reads use plain-array-safe shape handling (`is_array($result)` + `$result[0]`), so not inert vs the live `PhlixMySQLConnection` (the SV-3.1-rowquery landmine does not recur here). No ctor/DI signature change to Recorder or either entrypoint — the optional params are wired only through the shared `LiveTvServicesProvider`, so both index.php and start.php get identical wiring; no dual-entrypoint mirror needed. SV-4.3 ComskipRunner wedged-process SIGKILL timeout is reachable (poll loop checks the hrtime deadline every ~100ms select tick) and covered by a test. `RecordingHooks`/`ComskipPostProcessor`/ `MarkerService` confirmed dormant (never constructed/wired) — no parallel comskip path activated. Findings: 1. `src/Common/Container/Providers/LiveTvServicesProvider.php:173-177` — STALE DOC (low). The comment on the `RecordingMediaRegistrar` factory still reads "(Comskip chapter-marker attachment to the real media item is the SEPARATE, deferred SV-3.1d-comskip sub-step, gated on SV-4.3 — NOT wired here.)". That sub-step is now COMPLETE and wired ~35 lines above in the sibling `ComskipLifecycleManager` factory (the `ChapterMarkerService` injected into `ComskipIntegration` at lines 153-161). The parenthetical now misleads a maintainer into thinking commercial chapter-marker attachment is still unimplemented/ deferred. Recommend updating it to note comskip marker attachment is wired via the ComskipLifecycleManager factory. (Documentation only — no behavioral impact.) ## Orchestrator — SV-3.1d-comskip DONE (2026-07-12, perf-5) - [x] SV-3.1d-comskip — impl 5700403e + tests d18a8fe8; REVIEW returned 1 low finding (stale wiring comment); FIX f44bf5da (comment corrected); re-review waived (finding was a verbatim comment-only correction, no behavioral surface; reviewer had fully vetted code). Tests 70/70 green, phpstan L9 clean. - DVR stack (SV-3.1 a/b0/c/d/e + rowquery + comskip) now CODE-COMPLETE. OWED: Docs cycle (batched) + on-box end-to-end record→complete→playable+markers verify (start.php/Timer/real comskip outside CI). - Server active: SV-4.2 (X1 server-STOP half) IN PROGRESS. ## Implementer — SV-4.2 (detached-ffmpeg cancellation + apply transcode_timeout, [S-F23], X1 server-STOP half) — 2026-07-12 Closed the three re-audit GAPS (worklog :2176): (1) the on-demand PER-SEGMENT encode path (`FfmpegRunner::launchDetachedSegment`) had NO `timeout` and NO PID tracking — the exact scrub-storm orphan; (2) no kill of an abandoned encode; (3) `RelayConsumer::onHttpCancel` did not kill the ffmpeg. The whole-file/CMAF `buildDetachedCommand` + `Recorder` SIGTERM→SIGKILL were already done in the earlier SV-4.2 pass and are untouched. ### Files changed - **NEW `src/Media/Transcoding/SegmentProcessRegistry.php`** — per-worker in-memory map `cancelKey => [pid,...]` with `register/release/kill/registeredKeyCount/pidsFor`. `kill()` is coroutine-safe (SIGTERM, bounded hrtime grace wait via `Coroutine::sleep` when `getCid()>0` else `usleep`, then SIGKILL if still alive) and drops the entry (no leak). Signal-sender + liveness-probe are injectable so tests spawn/kill no real processes; defaults use `posix_kill` with a `kill` shell fallback. Bounded by the release-in-`finally` contract (resident-memory discipline). - **`FfmpegRunner.php`** — new `?SegmentProcessRegistry $segmentRegistry` (setter-injected, mirroring `setConfig`, so the ctor signature/tests are unchanged). `launchDetachedSegment` now builds via new **public** `buildDetachedSegmentCommand()` which wraps the atomic-publish chain (`encode && mv || rm`) in `timeout sh -c` (from the existing `getTranscodeTimeout()`, config `config/ffmpeg.php` `transcode_timeout`=7200) and registers the spawned PID under the cancel key. `startSegmentEncode()` gained an optional `?string $cancelKey` (defaults to `$outFile`). Added `releaseSegmentProcess()` / `killSegmentProcess()` delegators. - **`TranscodeManager.php`** — both `ensureSegment` launch sites now pass `$final` as the cancel key; both `finally` blocks now, for the encode WE launched, `releaseSegmentProcess($final)` when the segment published (already exited) or `killSegmentProcess($final)` when it did not (timed-out/hung/abandoned) — the wait-timeout orphan killer. `timeout ` on the child is the outer backstop. - **`RelayConsumer.php`** — setter `setSegmentProcessRegistry()`; `onHttpCancel` now calls `registry?->kill((string)$channelId)` before `closeLocalConnection()`. NOTE documented in code: the relay-tunnel worker is a separate process from HTTP workers, so for cross-process proxied traffic the *effective* abort remains `closeLocalConnection()` (→ the HTTP worker's poll-loop wait-timeout kill); the registry kill covers same-worker traffic (the relay fork's own `RelayRequestDispatcher` DOES launch encodes in-process) and is the request-keyed hook. - **`TranscodeServicesProvider.php`** — `SegmentProcessRegistry` registered as a per-worker DI singleton; injected into `FfmpegRunner` via the setter. Central provider = shared by BOTH `public/index.php` and `start.php` (both call `ContainerFactory::create`), so no dual-entrypoint duplication needed. - **`start.php`** — relay-tunnel worker wires the registry into the `RelayConsumer`. ### Acceptance mapping - *Wrap detached segment encode in `timeout ` from `transcode_timeout`* → `buildDetachedSegmentCommand` (test: `FfmpegRunnerTest::testBuildDetachedSegmentCommandWrapsInTimeout` / `...OmitsTimeoutWhenZero`). - *Register spawned PID keyed for cancel* → `SegmentProcessRegistry` + `launchDetachedSegment` registration (tests: `SegmentProcessRegistryTest`, `FfmpegRunnerTest::testSegmentProcessLifecycleDelegatesToRegistry`). - *On wait-timeout, kill the tracked PID; release on completion; no leak* → `TranscodeManagerTest::testEnsureSegmentKillsAbandonedEncodeOnWaitTimeout` / `testEnsureSegmentReleasesRegistryOnCompletion`. - *onHttpCancel kills tracked PIDs* → `RelayConsumerTest::test_http_cancel_kills_tracked_segment_encode` (mock signal sender). ### Deferred (noted follow-up sub-step) - **Client/connection-disconnect immediate kill + request-keyed onHttpCancel effectiveness.** Making onHttpCancel/disconnect kill the encode *directly* (rather than via the poll-loop wait-timeout) needs the encode registered under a request/connection-scoped cancel key (thread the relay request id / a per-connection token through `RequestContext` into the transcode cancel key) plus a direct-connection disconnect hook (the HTTP worker uses keep-alive `onMessage` only; no per-response `onClose` is wired today). Out of the ~2-3 file / ~200 line budget; the wait-timeout kill + `timeout ` backstop already bound orphan CPU, so this is a latency optimization, not a correctness gap. ### Verification - `phpunit` (SegmentProcessRegistry/FfmpegRunner/TranscodeManager/RelayConsumer): 150/150 OK. - Full `--testsuite Unit`: 4973 tests, 0 failures/errors; only 4 PRE-EXISTING warnings (`TranscodeManager.php:2188-2191` undefined `color_*` keys, code not touched here). - `phpstan -c phpstan.neon.dist` on all 5 touched src files: No errors. - `phpcs --standard=PSR12` src: 0 errors (11 pre-existing line-length warnings in TranscodeManager, none on added lines). Test snake_case method-name errors are the per-file existing convention and tests are outside the phpcs gate (`phpcs src/`). ## Reviewer (per-step SV-4.2) — 2026-07-12 Scope confirmed in-bounds (SegmentProcessRegistry, FfmpegRunner, TranscodeManager, RelayConsumer, TranscodeServicesProvider, start.php). Verification: `phpunit --filter 'SegmentProcessRegistry|FfmpegRunner|TranscodeManager|RelayConsumer'` = 188 tests OK (4 pre-existing `color_*` warnings, untouched); `phpstan -c phpstan.neon.dist` on all 5 touched src files = No errors. Cancel-key match, `timeout` wrapping, and registry semantics were read directly (tests alone do not settle these). Findings (most-severe first): 1. **[Medium] Killed segment encode leaks its `.part-*` temp, which then corrupts cap + dedup accounting and can livelock playback.** `TranscodeManager.php:854` / `:1024` call `killSegmentProcess($final)` on wait-timeout, which SIGTERM/SIGKILLs the tracked `timeout` process (group). That terminates the `sh -c 'ffmpeg && mv -f tmp final || rm -f tmp'` chain mid-flight, so the `|| rm -f ` cleanup NEVER runs when the shell is signalled — the `.part-*` temp survives on disk. Both the global cap (`countInFlightSegmentEncodes()` `TranscodeManager.php:1234`, globs `seg-*.ts.part-*`) and the dedup snapshot (`reconcileInFlightSegments()` `:1273`, same glob) then treat the DEAD encode as still in-flight. Failure scenario: a scrub-storm's killed encodes each leave a corpse `.part-*` that counts against `maxConcurrentSegments` until the LRU sweep (`sweepSegmentCache`/`removeJobDir` `:1467`) evicts the whole job dir — i.e. LONGER than if the encode had run to natural completion — causing spurious 503 (`SegmentBusyException`) for legitimate playback; and a retry for the same `$final` sees the corpse as "in-flight," piggybacks on it, times out doing nothing, and can livelock until eviction. Why it matters: this partially inverts S-F23 (CPU is freed but cap occupancy gets WORSE) and can make a segment permanently unservable in that job dir. Fix: after `killSegmentProcess($final)`, `glob("{$final}.part-*")` + `@unlink()` the orphaned temp(s). Also the `buildDetachedSegmentCommand` docblock (`FfmpegRunner.php:2048-2050`) and the TranscodeManager finally comments (`:850`, `:1023`) claim the `timeout` kill "also removes the .part-* temp via the trailing rm" — that is incorrect; the `rm` only runs when ffmpeg exits nonzero on its own, not when the shell/group is signalled. 2. **[Medium] Wait-timeout kill cannot distinguish an abandoned seek from a slow-but-wanted encode; for encodes slower than `segmentMaxWaitMs` (30 s) it converts "eventually plays" into "killed + restarted."** `TranscodeManager.php:820`/`:854`: the poll loop waits `SEGMENT_MAX_WAIT_MS = 30000` (`:542`, not overridden in the provider) then unconditionally kills the encode if the segment has not published. There is no client-disconnect signal (the implementer's own deferred note), so a segment the client is STILL waiting on — a heavy software 4K/HEVC transcode on a GPU-less box (MEMORY confirms such boxes exist, "no GPU → SW transcode") can exceed 30 s — is killed at 30 s. Pre-SV-4.2 the encode was left running so the client's retry piggybacked on it (via the `.part-*` dedup) and it published progressively. Failure scenario: for a >30 s segment the first call kills at 30 s, the retry re-launches fresh (or, per finding 1, piggybacks on the corpse), and the segment either never completes or burns more aggregate CPU than before. The AC does say "kill tracked PIDs on wait-timeout," so the kill itself is AC-compliant — but combined with finding 1 the interaction is harmful; worth a guard (e.g. only kill when the client is known gone, or clean the temp so a fresh relaunch is possible) or at least an explicit documented risk. Note either way as required by the step brief. 3. **[Low] `RelayConsumer::onHttpCancel` registry kill is keyed on the wrong namespace and is inert (confirmed).** `RelayConsumer.php:1490` calls `registry?->kill((string) $channelId)`, but encodes are registered under the segment path `$final` (`TranscodeManager.php:814`/`:1010` → `FfmpegRunner::launchDetachedSegment` registers under `$cancelKey ?? $outFile` = `$final`). `$channelId` is the relay routing id, never a segment path, so the two key spaces never intersect: `onHttpCancel`'s kill always returns 0 and the `if ($killed > 0)` log never fires. This is the "green but inert" case for criterion 1 — however the implementer explicitly documents it (`RelayConsumer.php:222-229`, worklog "Deferred") and the EFFECTIVE relay abort is `closeLocalConnection()` → the HTTP worker's poll-loop wait-timeout kill, which IS keyed by `$final` and does match. Per the step's criterion-6 guidance (only a finding if the relay cancel path itself is incomplete) this is an acknowledged deferred follow-up, not a hard AC gap: the relay STOP path works via the wait-timeout kill. Flagged so the coordinator/future maintainer knows the `onHttpCancel` registry-kill line is presently dead code and its cancellation effectiveness is entirely coupled to finding 2's wait-timeout path (i.e. bounded by 30 s, not immediate). 4. **[Low] SIGKILL escalation targets the `timeout` wrapper, not ffmpeg; if SIGTERM forwarding fails ffmpeg is orphaned.** The registered PID is the `timeout` process (`nohup` execs `timeout`; `$!` in `buildDetachedSegmentCommand` `FfmpegRunner.php:2117` is that PID). `SegmentProcessRegistry::terminate()` sends SIGTERM to it — GNU coreutils `timeout` forwards that to the child process group, reaching ffmpeg (OK in the normal case). But the SIGKILL escalation (`SegmentProcessRegistry.php:186`) sends SIGKILL to `timeout`, which cannot be caught, so `timeout` dies WITHOUT forwarding and ffmpeg is left orphaned in a now-parentless group with no timer to reap it — it runs to completion. Failure scenario: any case where the graceful SIGTERM did not propagate within the 0.5 s grace, the "forced" kill does not actually reach ffmpeg. Low severity (SIGTERM forwarding normally works). Consider signalling the process group (negative PID) or launching with `timeout -k -s TERM` so `timeout` self-escalates to the child. Non-findings verified: dual-entrypoint OK (FfmpegRunner registry wired via the shared `TranscodeServicesProvider` consumed by both `public/index.php` and `start.php`; `RelayConsumer` runs only in `start.php`, so no index.php divergence). Async/resident-memory discipline OK (`SegmentProcessRegistry::cooperativeSleep` guards `getCid()>0`; no blocking `sleep`; posix_kill non-blocking; registry bounded by release/kill-in-`finally`; no request state in static/global — `getTranscodeTimeout`'s `static` caches only immutable config). `timeout` quoting OK (structure identical to the pre-existing `nohup sh -c ''`, just inserts `timeout `; nested `escapeshellarg` handled correctly). SV-4.1 reservation serializes per-worker launches so the registry key `$final` does not double-register within a worker. ## Fixer (per-step SV-4.2) — 2026-07-12 Fixed ALL 4 reviewer findings coherently. The unifying redesign: the per-request 30 s poll wait-timeout is NOT abandonment, so it must RELEASE (stop tracking) rather than KILL; the real kill fires only on genuine abandonment (HTTP_CANCEL), now wired to actually find the encode. Files changed (absolute): - **`src/Media/Transcoding/SegmentProcessRegistry.php`** — two-level keying: primary key = segment path (`$final`), optional GROUP = relay channel/request id, with reverse links so a drop always tears down the group (no leak). New `killGroup($group)` (kills every key a channel launched), `releaseAfterWaitTimeout($key)` (release-only; cleans the `.part-*` temp IFF the encode is already dead — never kills or touches a live encode's temp), and an injectable **temp cleaner** invoked on every `kill()` (globs `{$key}.part-*` + `@unlink`). The default signal sender now targets the process **GROUP** (`posix_kill(-$pid,$sig)`), and liveness still probes the leader. `registeredGroupCount()` added for leak assertions. → **finding #1** (temp cleaned on kill; docblock corrected), **#3** (group kill), **#4** (group-signal reaches ffmpeg, not just the wrapper). - **`src/Media/Transcoding/FfmpegRunner.php`** — `buildDetachedSegmentCommand` now emits `nohup setsid timeout -k -s TERM sh -c '' … & echo $!`. `setsid` makes the launched PID a process-group leader (PGID==PID, verified on-box) so a cancel can group-signal ffmpeg directly; `timeout -k -s TERM` makes `timeout` self-escalate to SIGKILL of its child group (backstop). New const `TIMEOUT_KILL_GRACE_SECONDS`. `startSegmentEncode`/`launchDetachedSegment` gained an optional `$cancelGroup` (registered alongside the segment key). New `releaseSegmentProcessAfterWaitTimeout()` delegator. Docblock corrected (the `|| rm` does NOT run when the chain is signalled). → **findings #4 & #1**. - **`src/Media/Transcoding/TranscodeManager.php`** — both `ensureSegment` finally blocks now, on wait-timeout (`!is_file($final)`), call `releaseSegmentProcessAfterWaitTimeout($final)` instead of `killSegmentProcess($final)` — a slow-but-wanted SW 4K/HEVC encode is left to finish and publish for the retrying requester. Both launch sites pass `RequestContext::getRelayCancelGroup()` as the cancel group. → **findings #1 & #2**. - **`src/Server/Http/RequestContext.php`** — new `KEY_RELAY_CANCEL_GROUP` + set/get/clearRelayCancelGroup (canonical per-coroutine store; works in both entrypoints). - **`src/Hub/RelayConsumer.php`** — `dispatchWithDeadline` now publishes the channel/request id as the relay cancel group into `RequestContext` for the dispatch duration (cleared in a `finally`; dispatch body extracted to `dispatchWithDeadlineInner`). `onHttpCancel` calls `killGroup((string)$channelId)` (was an inert `kill($channelId)`). Property docblock rewritten — the relay fork dispatches in-process, so encodes register into the same registry singleton and a cancel now finds them by channel id. → **finding #3**. **Channel→segment key mapping (how resolved):** threaded via `RequestContext` (the plan's preferred "register under both keys", implemented as a leak-free group index). The relay fork dispatches HTTP_REQUEST frames IN-PROCESS via its own `RelayRequestDispatcher` sharing the container's `SegmentProcessRegistry` singleton, so the encode a relayed segment request launches registers under both `$final` (primary) and the channel id (group). `onHttpCancel` → `killGroup(channelId)` → finds + kills + cleans temp. No `RequestContext` threading is needed in `public/index.php` (direct-LAN requests carry no relay group → group is null → encode tracked by path only, backward-compatible). **AC reconciliation:** the AC says "kill on wait-timeout / client disconnect." "Wait-timeout" is satisfied by the `timeout ` encode backstop (which now self-escalates via `-k`), NOT by the per-request 30 s poll wait (killing there murdered slow-but-wanted SW encodes — finding #2 — so that path is release-only). "Client disconnect/cancel" is satisfied by the now-working `onHttpCancel`→`killGroup` path (finding #3). **Verification:** - `phpunit --filter 'SegmentProcessRegistry|FfmpegRunner|TranscodeManager|RelayConsumer|RequestContext'` = 197 tests, 0 fail (4 pre-existing `color_*` warnings, untouched code). - Full `--testsuite Unit` = 4982 tests, 0 failures/errors, 5 pre-existing skips. - `phpstan -c phpstan.neon.dist` on all 5 touched src files = No errors. - `phpcs --standard=PSR12` = 0 errors (only pre-existing line-length warnings; none on my lines). - On-box `nohup setsid timeout … & echo $!` confirmed to yield a group-leader PID whose whole group (timeout→sh→child) is killed by `kill -TERM -$PID`. New/updated tests: registry temp-cleanup-on-kill, releaseAfterWaitTimeout (alive=no-kill/no-clean, dead=clean), killGroup semantics + group-teardown-no-leak; FfmpegRunner command-shape (`setsid` + `timeout -k -s TERM`) + `releaseSegmentProcessAfterWaitTimeout` delegation; TranscodeManager wait-timeout is release-only (never kills); RelayConsumer cancel via group + an end-to-end test that the dispatch publishes the cancel group and a later HTTP_CANCEL kills the encode launched during dispatch. ## Reviewer (re-review per-step SV-4.2, after fix 3b6c6a3b) — 2026-07-12 Re-reviewed the 4-finding fix by READING the code (not trusting green). Verification: `phpunit --filter 'SegmentProcessRegistry|FfmpegRunner|TranscodeManager|RelayConsumer|RequestContext'` = 197 OK (4 pre-existing `color_*` warnings, untouched); `phpstan -c phpstan.neon.dist` on all 5 touched src files = No errors. Prior findings — all CONFIRMED genuinely fixed: - **#3 (killGroup end-to-end, was the inert bug) — FIXED, traced link-by-link.** (a) `RelayConsumer::dispatchWithDeadline` publishes `(string)$requestId` into `RequestContext::setRelayCancelGroup` (coroutine-local `support\Context`), cleared in `finally`; (b) both `TranscodeManager::ensureSegment` launch sites pass `RequestContext::getRelayCancelGroup()` → `FfmpegRunner::startSegmentEncode`→`launchDetachedSegment`→`registry->register($final, $pid, $group)` — registration is synchronous within the same coroutine that set the group, so the value is visible; (c) `onHttpCancel` reads `$frame->channelId()` — the SAME field `onHttpRequest` uses for `$requestId` — and calls `killGroup((string)$channelId)`. Registry is ONE shared instance: `start.php` builds `RelayRequestDispatcher(new Application($container,…), $container)` and `$container->get(SegmentProcessRegistry::class)` for the consumer; `FfmpegRunner`'s factory resolves the SAME `$c->get(SegmentProcessRegistry::class)` — PHP-DI caches `factory()` entries as per-container singletons, so the relay fork's in-process dispatch and the consumer share the registry. Id spaces match; instance shared; cancel is no longer inert. - **#2 (release-only, don't kill live encode) — FIXED.** Both `finally` blocks call `releaseSegmentProcessAfterWaitTimeout($final)` (not `killSegmentProcess`) on the `!is_file($final)` branch. `releaseAfterWaitTimeout` probes `isAlive` per pid; if ANY alive it drops tracking only and does NOT signal and does NOT touch the temp; only when all dead does it clean the corpse `.part-*`. A signalled/`timeout`-killed encode is dead → temp cleaned; a live slow SW 4K/HEVC encode is left completely alone to publish for the retrying requester. Liveness check has no destructive race (it never acts on the live branch). - **#1 (killed encode leaked `.part-*`) — FIXED.** `kill()` runs `tempCleaner` (glob `{$key}.part-*` + `@unlink`) after signalling; docblocks corrected (the `|| rm` does NOT run when the chain is signalled). Cap/dedup globs no longer count a killed encode's corpse. - **#4 (SIGKILL hit the wrapper, not ffmpeg) — FIXED.** Launch is `nohup setsid timeout -k 10 -s TERM sh -c '' … & echo $!`; `setsid` (invoked from a non-interactive `sh -c` background job, so not a group leader → no fork → PGID==PID==`$!`) makes the tracked pid the group leader; the default signal sender targets the GROUP (`posix_kill(-$pid,…)`) for BOTH SIGTERM and SIGKILL, reaching ffmpeg directly; `timeout -k … -s TERM` is a self-escalating backstop. `posix_kill` is non-blocking (coroutine-safe); the `kill --` shell fallback is guarded behind `!function_exists('posix_kill')`. No double-wrap. New findings from the fix (most-severe first): 1. **[Low] The `.part-*` temp cleaner can delete a *sibling worker's* live temp for the same segment path, wasting that encode.** `SegmentProcessRegistry::defaultTempCleaner` (`SegmentProcessRegistry.php:414-427`) globs `{$final}.part-*` and `@unlink`s ALL matches. But `TranscodeManager` explicitly tolerates cross-worker duplicate encodes of the same `$final` within the reconcile window (`TranscodeManager.php:770-772`: "A sibling worker's view is eventually-consistent … a missed dedup merely costs one redundant duplicate encode"). Each worker writes a DISTINCT temp `{$final}.part-` (`FfmpegRunner::startSegmentEncode` `:2038`). Failure scenario: worker A (relay) encodes segment X into `X.part-aaa` and worker B (a direct-LAN HTTP worker) concurrently encodes the same X into `X.part-bbb`; client 1 abandons → `onHttpCancel`→`killGroup`→`kill(X)` globs `X.part-*` and unlinks BOTH — so B's still-running ffmpeg loses its output path and its final `mv -f X.part-bbb X` fails, wasting B's encode; client 2's poll then times out and must relaunch. Same collateral hit is possible from `releaseAfterWaitTimeout`'s dead-branch cleaner. Why it matters: the fix converts a previously-benign tolerated race ("one redundant duplicate encode") into one where the sibling's work is destroyed. Severity LOW: it is self-healing (the atomic-publish invariant still holds — the FINAL file is never globbed/deleted, only `.part-*` temps — and client 2 retries and succeeds once A's reservation/temps are gone), and it requires two clients encoding the exact same variant+index within the ~1s cross-worker window (uncommon; the scrub-storm itself is single-client via the one relay worker, where SV-4.1's per-worker reservation prevents same-`$final` duplication entirely). Optional hardening: have the launcher pass the exact `$tmp` path it created to the registry and clean only that specific temp on kill, rather than globbing the whole `{$final}.part-*` family. Deferred edge (criterion 7) — judged ACCEPTABLE per design, NOT a finding: if a client abandons AFTER the 30s poll wait-timeout has already released the key (encode still running), `killGroup` finds nothing and the still-running encode falls back to the `timeout ` backstop. This is the documented "wait-timeout is not abandonment" trade-off; the `timeout -k -s TERM` wrapper bounds the orphan CPU, and the common abandonment case (HTTP_CANCEL arriving while the request/poll is still in flight, key still registered) is killed promptly. Acceptable. Non-findings verified: RequestContext threading is leak-free (set/`finally`-clear, coroutine-local `support\Context`; concurrent relayed requests don't cross-contaminate; direct-LAN `index.php` never sets it → null group → path-only tracking, back-compat). Dual-entrypoint parity OK (RequestContext under `src/Server/Http` reaches both entrypoints; registry via the shared `TranscodeServicesProvider`; `RelayConsumer` is `start.php`-only). No SV-4.1 regression (reservation logic untouched). Hub/shared wire contracts untouched. Count: 1 finding (Low). ## Implementer (re-review fix per-step SV-4.2 — precise-temp cleanup) — 2026-07-12 Resolved the single Low re-review finding: the `.part-*` temp cleaner could delete a *sibling worker's* LIVE temp for the same final segment path. Now each launcher's OWN `.part-` temp is cleaned, never the `{$final}.part-*` family. Files changed (absolute): - `/home/sites/phlix/phlix-server/src/Media/Transcoding/SegmentProcessRegistry.php` - Added `private array $tmpsByKey` (key => list of the exact `.part-` temps THIS launcher created). - `register()` gained an optional 4th param `?string $tmp`; a non-empty tmp is recorded under the key. Back-compat: default null, existing 3-arg calls unaffected. - `kill()` and `releaseAfterWaitTimeout()` now snapshot `$tmpsByKey[$key]` before `drop()` and clean ONLY those specific temps (via new private `cleanTemps()`), instead of `glob({$key}.part-*)`. - `drop()` also unsets `$tmpsByKey[$key]`. - `defaultTempCleaner` signature is now `fn(string $tmp): void` — `@unlink($tmp)` guarded by `file_exists`, NO glob. (Dropped a redundant `is_string` guard the param type already guarantees — phpstan `function.alreadyNarrowedType`.) - Docblocks updated (class comment, tempCleaner property, register, kill). - `/home/sites/phlix/phlix-server/src/Media/Transcoding/FfmpegRunner.php` - `launchDetachedSegment()` threads its `$tmp` into `register($cancelKey ?? $outFile, $childPid, $cancelGroup, $tmp)`. `startSegmentEncode` already generated `$tmp` and passed it down — no signature change needed there. - `/home/sites/phlix/phlix-server/tests/Unit/Media/Transcoding/SegmentProcessRegistryTest.php` - Injected cleaner now records the tmp path (not the key); existing kill/release/killGroup temp-cleanup tests register with an explicit `.part-` tmp and assert that exact path is (or is not) cleaned. - NEW `test_kill_with_default_cleaner_removes_only_own_temp_not_sibling`: creates two real files `X.part-aaaaaaaa` (own) + `X.part-bbbbbbbb` (sibling's live temp) for the same final `X`, registers only the own temp, kills, and asserts the own temp is removed, the sibling temp SURVIVES, and the final `X` is never touched. Exercises the REAL default cleaner. Kill semantics, keys, release-only wait-timeout, killGroup, setsid/`timeout -k`, atomic publish (from 3b6c6a3b) all unchanged. SV-4.1 reservation untouched. Hub/shared untouched. Register param is optional → no dual-entrypoint (index.php/start.php) divergence; registry still wired via the shared `TranscodeServicesProvider`. Verification: - `phpunit --filter 'SegmentProcessRegistry|FfmpegRunner|TranscodeManager|RelayConsumer'` → 198 OK (4 pre-existing risky warnings, untouched). - `phpunit --testsuite Unit` → 4983 tests, 38746 assertions, 5 skipped, 0 failures. - `phpstan analyze -c phpstan.neon.dist` on both touched src files → No errors. - `phpcs --standard=PSR12` → SegmentProcessRegistry.php clean; FfmpegRunner.php 1 pre-existing 120-char warning at line 838 (unrelated to this change). ## Orchestrator — SV-4.2 DONE (2026-07-12, perf-5) - [x] SV-4.2 detached-ffmpeg cancellation + transcode_timeout COMPLETE. impl 470111ad + tests 9fa01804; REVIEW (4 findings: 2 Med temp-leak/kill-slow-wanted, 2 Low) → FIX 3b6c6a3b (release-only wait-timeout, real killGroup via RequestContext, temp cleanup, setsid+`timeout -k -s TERM`); RE-REVIEW (1 Low: family-glob temp cleaner) → FIX 3c73fe0a (unlink only launcher's own .part).

GAP: DI-resolution branch + static-map-served assertion untested. - **TestEngineer — 2026-07-18 — GREEN (gap closed).** Added 5 tests to `tests/Unit/Server/Http/RouterTest.php` (+ fixture `tests/Unit/Server/Http/Fixtures/RouterFixtureController.php`): (1) DI branch — mock PSR-11 `ContainerInterface`, `expects(once)->get(RouterFixtureController::class)` returns a spy, asserts the container-returned instance is the one invoked; (2) fallback branch — no container → `new $class()` (marked Response can only come from direct instantiation); (3) static-map fast path — a `/{slug}` parametric route registered alongside `/fast`; its closure never runs on the `/fast` static hit, proving the regex loop is skipped regardless of registration order; (4) HEAD via static map — HEAD `/health` (GET-only static) resolves through `dispatchAsHead()` static lookup, `headOnly=true` (a parametric GET route is also registered to satisfy the `isset(routes['GET'])` fallback guard); (5) BadMethodCallException on the array/DI path — resolved handler returning a non-Response throws. RouterTest 11/11 green. Full Unit **5725/0 fail/0 err/8 skip** (5720 baseline +5). phpstan L9 `[OK] No errors`; phpcs PSR12 clean on both changed test files + config. LATENT EDGE-CASE (not fixed, harmless in prod): the HEAD→GET fallback guard checks only `isset($this->routes['GET'])` (parametric map); if a GET path existed ONLY as a *static* route with ZERO parametric GET routes registered, HEAD to it would 404 instead of reaching `dispatchAsHead()`'s static branch. Prod always has parametric GET routes so it never triggers; flagged for a future guard tweak (`|| isset($this->staticRoutes['GET'])`). - **TestEngineer — 2026-07-18 — HARDENED (latent edge fixed).** Applied the flagged guard tweak in `src/Server/Http/Router.php` `dispatch()`: both HEAD→GET fallback guards now read `isset($this->routes['GET']) || isset($this->staticRoutes['GET'])`, and `dispatchAsHead()`'s parametric loop is `foreach (($this->routes['GET'] ?? []) as ...)` so a static-only GET map can't warn on a null foreach. Added 2 RouterTest cases: `testHeadResolvesStaticOnlyGetRouteWithNoParametricGetRoutes` (register `/ping` as the SOLE GET route → purely static, `routes['GET']` unset → HEAD `/ping` now resolves 200 + headOnly instead of 404) and `testHeadStillReturns404WhenNoGetRouteMatchesPath` (normal case unchanged — HEAD to an unregistered path still 404s). Separate commit from the SV-4.12 tests. - SV-4.9 Migration ledger — **NOT-DONE (INERT).** `migrations/076_schema_migrations.sql` creates the table but `grep schema_migrations src/ scripts/ bin/` = ZERO hits; MigrationRunner still applies EVERY .sql every boot (its own docblock says "no migration-tracking table"). 076 header falsely claims run-migrations.php consults it. → COMPLETE: write+consult ledger (INSERT ON DUP KEY after clean apply; skip name+checksum match; log checksum divergence; bootstrap-create/order 076 first; keep error-squelch as safety net). - SV-4.10 provider-priority single-source + hrtime — **PARTIAL.** hrtime DONE (MediaScanner:420/432, no microtime left).

W1/W2/W3.3-3.4 re-audits still pending. ## Implementer — SV-4.5 (Roku/HdHomeRun/MusicBrainz blocking-I/O → coroutine-aware async) — 2026-07-13 NOT-DONE verdict cleared. All four audited targets converted; reused the shared `Phlix\Common\Runtime\WorkerContext` guard (`isEventLoopRunning()` + `inCoroutine()`) — the SAME coroutine-vs-blocking decision every async client here uses — so no new inconsistent (always-false) guard was introduced. Files changed (src): - `src/Media/Metadata/Provider/MusicMetadataProviderTrait.php` — `rateLimit()` rewritten from a PER-INSTANCE `$lastRequestTime` to a **static-per-host** limiter: `private static array $hostLastRequestTime` keyed by the provider's `BASE_URL` host (derived via new `rateLimitBucket()` — `parse_url(...HOST)`, lower-cased; falls back to class name). SHARED across instances of a provider (trait-statics are per-using-class, so all MusicBrainzProvider instances share one bucket; keyed-by-host so distinct APIs stay independent). **BOUNDED**: `RATE_LIMIT_HOST_CAP = 64` with unset+reassign LRU touch + `array_key_first` eviction of the oldest host once the map exceeds the cap. The wait is coroutine-aware via new `rateLimitSleep()` (`WorkerContext::inCoroutine()` → `\Swoole\Coroutine::sleep()`, else blocking `usleep`). - `src/Roku/RokuEcpClient.php` — `usleep(500000)` (channel-launch fallback) → `coroutineAwareSleep(0.5)`; `get()`/`post()` now route through a new `fetch()` that chooses `fetchAsync()` (workerman/http-client + `Swoole\Coroutine\Channel` cooperative wait) vs `fetchBlocking()` (stream `file_get_contents`) via new protected `preferAsyncHttp()` seam. - `src/Roku/RemoteRokuClient.php` — the `usleep(500000)` no-Timer fallback → `coroutineAwareSleep(0.5)`; the three `file_get_contents` sites (deferred-play, direct POST, `relayLaunchChannel`) collapsed into `httpPost()` → `httpPostAsync()` / `httpPostBlocking()` chosen via protected `preferAsyncHttp()`. - `src/LiveTv/Tuners/HdHomeRun/HdHomeRunTunerDriver.php` — `scanChannels()` `usleep(500000)` → new `coroutineAwareSleep(0.5)`. Tests (added/updated): - NEW `tests/Unit/Media/Metadata/Provider/MusicMetadataRateLimitTest.php` (+ fixture `RateLimitTraitFixture.php`): bucket-key = host; **state SHARED across two instances** for the same host (second instance waits out the window); first-request no-wait; **map BOUNDED** (prefill cap, one add → one LRU eviction of the oldest, count stays at cap); in-coroutine wait **yields** the loop (sibling coroutine interleaves during the wait → proves `Coroutine::sleep`, not blocking `usleep`). - NEW `tests/Unit/Roku/RemoteRokuClientTest.php` (+ seam `RemoteRokuClientAsyncSeamStub.php`): `preferAsyncHttp()` false outside a coroutine (blocking chosen); `httpPost()` routes to the async transport when the async decision is active (blocking NOT called); coroutine sleep yields. - `tests/Unit/Roku/RokuEcpClientTest.php` — added the same three assertions (blocking-outside-coroutine, async-routing-when-preferred, cooperative sleep). - `tests/Unit/LiveTv/Tuners/HdHomeRun/HdHomeRunTunerDriverTest.php` — added the cooperative-sleep yield test. - Updated `MusicBrainzProviderTest`/`AudioDbProviderTest` rate-limit tests: reflect the new static `hostLastRequestTime` (musicbrainz.org / theaudiodb.com buckets) instead of the removed per-instance property. Verification: relevant dirs green (87/87); full `--testsuite Unit` **4995 tests, 0 errors / 0 failures** (4 pre-existing TranscodeManager color-key warnings + 5 skips are environmental); `phpstan -c phpstan.neon.dist` **0 errors**; `phpcs --standard=PSR12` clean on all changed files (pre-existing snake_case method-name warnings in the two provider tests are unrelated/note-and-continue). Deferral note: RokuEcpClient/RemoteRokuClient async transport only activates under a live worker+coroutine (`WorkerContext::isEventLoopRunning()` gate) exactly like MetadataHttpClient/ WebhookHttpClient; the blocking stream path remains for CLI/tests. The MB limiter's trait-static is per-using-class (shared across instances of a provider, keyed by host) — a single provider class per remote host, so this fully addresses the "concurrent instances collectively violate" finding; a truly cross-class global map was intentionally not added (would need a new shared file, out of the 4-file scope). ## Orchestrator — SV-4.5 implemented (2026-07-12/13, perf-5) - [x] SV-4.5 async I/O — impl f1576377, REVIEW NO FINDINGS (Channel gated on isEventLoopRunning()&&inCoroutine(); MB static-per-host LRU cap64; swoole-ON coroutine tests execute). Full Unit 4995/0. DONE (docs batched). ## Reviewer (per-step SV-4.5) — 2026-07-13 Reviewed commit `f1576377` against the S-F15/S-F16 findings, the SV-4.5 acceptance, and the highest-priority Channel-gate bug class (SV-0.4/SV-4.11). Read the actual gates (not just green tests); ran the targeted suite (98/98, swoole ON so the coroutine-yield tests genuinely execute, not skip) + phpstan (0 in-context). Criterion-by-criterion: 1. **Channel gate — CORRECT.** `RokuEcpClient::preferAsyncHttp()` (:368-371) and `RemoteRokuClient::preferAsyncHttp()` (:224-227) both return `WorkerContext::isEventLoopRunning() && WorkerContext::inCoroutine()`. The `Swoole\Coroutine\Channel::pop()` async path (`fetchAsync`/`httpPostAsync`) is reachable ONLY when `getCid()>0`. NOT the isEventLoopRunning()-alone defect. 2. **coroutineAwareSleep / rateLimitSleep — CORRECT.** All three sleeps (RokuEcpClient:448, RemoteRokuClient:297, HdHomeRunTunerDriver:coroutineAwareSleep, trait rateLimitSleep:128) gate `Swoole\Coroutine::sleep()` on `inCoroutine()`, blocking `usleep` only outside a coroutine — never a blocking usleep in-coroutine. 3. **MB static-per-host limiter — CORRECT.** `private static array $hostLastRequestTime` shared across instances of a using-class (proven by testStateIsSharedAcrossInstances); keyed by lower-cased `BASE_URL` host; LRU-bounded at cap 64 with unset+reassign touch + array_key_first eviction (testHostMapIsBoundedWithLruEviction proves count stays at cap and the oldest host is evicted). Two using-classes (MusicBrainzProvider→musicbrainz.org, AudioDbProvider→theaudiodb.com) hit DISTINCT hosts, so the PHP per-using-class trait-static causes no double-spend — acceptable per the finding's guidance. 4. **Blocking path preserved — CORRECT.** fetchBlocking/httpPostBlocking retained and selected outside a coroutine (testPreferAsyncHttpIsFalseOutsideCoroutine). 5. **No new loop-blocking calls; workerman/http-client usage matches the sibling async clients' Channel(1)+push-on-success/error+pop(timeout) pattern.** No exit/die, no request state in statics beyond the bounded host map. 6. **Tests exercise the coroutine branch** (swoole present → the yield tests run and pass) and the shared-limiter + bounded-map behaviors. NO FINDINGS ## ON-BOX VERIFY (perf-5, 2026-07-13) — server @3c73fe0a (pre SV-4.5/4.9) PASS: migrations 077 applied; SV-4.7 WS auth on :8097 (token-less rejected / valid JWT accepted); SV-0.5 WS ping/reaper (pinged ~30s, reaped at t+77s per limit); >64KB bodied-relay round-trip. CANNOT-VERIFY: DVR end-to-end (livetv_tuners 0 rows, no tuner/hardware); QSV hwupload (box is a QEMU VM, bochs-drm, not Intel HW — boot probe chose software/libx264, VAAPI/NVENC correct). ⚠️ X1 direct-path FAIL: direct (non-relay) transcode client killed mid-encode → ffmpeg alive 7.4s+ (only `timeout 7200` backstop). ROOT CAUSE: `FfmpegRunner::killSegmentProcess()` has NO caller anywhere; only `killGroup()` (relay HTTP_CANCEL via RelayConsumer) is wired. Direct-LAN disconnects get no cancellation. → FOLLOW-UP SV-4.2-disconnect: wire killSegmentProcess to a direct-connection disconnect/abort hook (was the deferred piece; on-box proves real orphan-CPU impact). ## Re-audit (perf-5) — SV-1.7–1.10 - SV-1.7 range parser reuse — **DONE.** HttpHandler:752-766 uses TranscodeFileServer::parseRange (anchored, over-long clamp→206, suffix bytes=-N). Covered via HlsControllerTest/ThemeMediaStreamControllerTest (shared parser). Minor: direct serveMediaStream path itself untested (same static method). - SV-1.8 CSRF Origin exact-match (SECURITY) — **DONE (code).** RequestAuthenticator:223-244 hostsMatch exact compare, no str_ends_with; host:port handled; gate HttpHandler:126-140 (cookie-auth POST/PUT/DELETE/PATCH → 403 csrf.invalid_origin). GAP: ZERO CSRF tests (no RequestAuthenticatorTest) — plan mandated suffix-attack-rejected/port-accepted/cross-origin-rejected. → TEST. (Minor: no configured trusted-origins list, only own Host — fine for same-origin.) #### TestEngineer — 2026-07-18 (SV-1.8 test top-up) — GREEN New `tests/Unit/Server/Http/RequestAuthenticatorTest.php` (29 tests, 39 assertions): suffix bypass rejected both directions (`evil-example.com`, `example.com.evil.com`); exact same-origin accepted; port match accepted / mismatch + asymmetric-port both-ways rejected; Referer enforced identically (match/mismatch/unparseable); both-absent rejected; unparseable Origin rejected; Origin `''`/`'null'` skipped but Referer still enforced; safe methods (GET/HEAD/OPTIONS) allowed; malformed Host fail-safe (parseHostHeader fallback). Gate-level via `HttpHandler::__invoke` (mock TcpConnection): cookie-auth POST + bad Origin → **403 body `code=csrf.invalid_origin`**; bearer-auth POST + bad Origin → **bypasses gate (dispatches, 200)**. Coverage RequestAuthenticator.php **60/60 stmts (100%), 6/6 methods**. Verification (real output): `RequestAuthenticatorTest` = OK (29 tests, 39 assertions); full Unit = `Tests: 5713, Assertions: 41840, Skipped: 5` (0 fail/0 err; 5684 baseline + 29); phpstan L9 `[OK] No errors`; phpcs PSR12 exit 0 on the new file. Impl audit verdict: implementation correct, no production changes. NOTE: plan AC (`evil-example.com` rejected, host:port works, same-origin passes) is fully met by exact same-origin compare; a configured trusted-origins allowlist remains unimplemented (low-priority, NOT required by AC — not added). OBSERVATION (not a bug given the threat model): `Origin: ''` with NO Referer on a state-changing request returns true (empty-string origin skipped, both-absent early-check keyed on PHP `null` only) — browsers never emit an empty-string Origin cross-site, so no realistic CSRF vector; flagged for awareness, left as-is. - SV-1.9 ENOSPC guard — **DONE (code+wired).** TranscodeManager:1461-1484 ensureDiskSpace (disk_free_space vs minDiskSpaceBytes default 500MiB) called before startSegmentEncode @812/@1032; HlsController:147-156 catches SegmentCacheFullException→sweep+503+Retry-After. GAPS: ZERO ENOSPC tests; threshold NOT surfaced in config (TranscodeServicesProvider doesn't pass minDiskSpaceBytes; hardcoded default). → TEST + optional config key. - **TestEngineer/Implementer — 2026-07-18 — GREEN (gaps closed).** PART A config-wiring: added `hls.min_disk_space_bytes` (env `HLS_CACHE_MIN_FREE_BYTES`, default 500 MiB) to `config/server.php` next to its sibling segment-cache knobs (cache_max_bytes/cache_max_age) — that's where the provider reads `$appConfig['hls']`; `config/transcoding.php` is NOT exposed in `$appConfig` (only read by HwAccelConfig), so `['hls']` is the convention-consistent home. `TranscodeServicesProvider` now reads it and threads it to ctor **position 13** (`$minDiskSpaceBytes`); because args are positional, **position 12** (`$segmentMaxWaitMs`) is now passed as explicit `null` to preserve its existing default (SEGMENT_MAX_WAIT_MS) verbatim — no behavior change when the key is absent (null → 500 MiB ctor default). PHP-DI "skips optional params" landmine N/A: the manager is built by an explicit `factory()` closure, not autowiring. PART B tests (+7, all green): HlsControllerTest ×2 (legacy `seg-` + multi-variant `seg-v` routes → 503 + Retry-After **'3'** + `sweepSegmentCache()` once); TranscodeManagerTest ×3 (PHP_INT_MAX floor → SegmentCacheFullException before ffmpeg spawn; 1-byte floor → encode proceeds; bogus segment_dir → disk_free_space false → fail-open encode); TranscodeServicesProviderTest ×2 (absent key → 500 MiB default; set key → threaded through, read via reflection). Verification: targeted 3 files OK (153 tests); **full Unit 5720/0 fail/0 err/8 skipped** (5713 baseline +7); phpstan L9 `[OK] No errors`; phpcs PSR12 -n clean on `src/` provider + config. Files: `config/server.php`, `src/Common/Container/Providers/TranscodeServicesProvider.php`, `tests/Unit/Server/Http/Controllers/HlsControllerTest.php`, `tests/Unit/Media/Transcoding/TranscodeManagerTest.php`, `tests/Unit/Common/Container/Providers/TranscodeServicesProviderTest.php`. - **TestEngineer — 2026-07-18 — env-var rename (review nit).** Renamed the brand-new SV-1.9 env override in `config/server.php` from `HLS_CACHE_MIN_FREE_BYTES` → **`HLS_MIN_DISK_SPACE_BYTES`** so it mirrors its config key `min_disk_space_bytes` the way siblings do (`cache_max_bytes`↔`HLS_CACHE_MAX_BYTES`, `max_concurrent_segments`↔`HLS_MAX_CONCURRENT_SEGMENTS`). grep confirmed the old name appeared ONLY in `config/server.php` (the provider test reads the `min_disk_space_bytes` config KEY directly, not the env var, so no test/doc referenced it) — safe rename, no other references to update. Left the unrelated class const `TranscodeManager::SEGMENT_CACHE_MIN_FREE_BYTES` untouched (out of scope). Full Unit still 5725/0/0/8; phpcs clean on config. Separate commit. - SV-1.10 login rate limiter bound — **NOT-DONE (INERT).** DbLoginRateLimitStore.php (bounded, DELETE LIMIT 100 sweep) + migration 074 exist but store NEVER injected: AuthServicesProvider:167-175 autowires AuthManager naming logger/eventDispatcher/db/statsCollector/settingsRepository but NOT loginRateLimitStore → stays null → prod uses UNBOUNDED per-worker static $rateLimitStore (no sweep/LRU/cap; still ×workers). grep: zero DbLoginRateLimitStore refs outside AuthManager+its own file. Tests only hit the static fallback. → COMPLETE: add ->constructorParameter('loginRateLimitStore', get(DbLoginRateLimitStore::class)) in AuthServicesProvider; confirm mig 074 deploy; bound-or-test-restrict the static fallback; add DbLoginRateLimitStore bound/sweep test + prod-wiring test. (Parallels hub HB-4.6 login per-worker weakening — this DB store IS the shared/bounded fix on the server side.) ### Server queue refined: SV-4.9(running) → SV-4.11(Channel gate) → SV-1.10(wire DB login store, inert-security) → SV-0.8(findPathsMap library_id) → SV-4.10(provider-priority) → SV-0.9(batch cmd) → SV-4.4(webhook) → SV-3.1 f/g/h → SV-3.6(Trakt) → SV-4.13-finish(+:594) → SV-4.2-disconnect(wire killSegmentProcess) → TEST top-ups (SV-0.6/0.7/1.8-CSRF/1.9-ENOSPC/4.8/4.12). Audits still owed: SV-1.1–1.6, SV-2.2/2.3/2.7(spawning), SV-3.3/3.4. ## Implementer — SV-4.9 (wire schema_migrations ledger) — 2026-07-13 Verdict was NOT-DONE (INERT): `migrations/076_schema_migrations.sql` created the table but nothing read/wrote it; `MigrationRunner` re-applied every `.sql` every boot. Now wired. Files changed: - `src/Common/Database/MigrationRunner.php` — ledger consult + record: - `run()`: after resolving the connection (and early-returning if there are no files, so the empty-dir test still issues zero queries), bootstrap `CREATE TABLE IF NOT EXISTS schema_migrations` (new `ensureLedgerTable()`), then `loadLedger()` (`SELECT name, checksum`). Per file: compute `md5($contents)`; if recorded+checksum-match → SKIP without executing (bump `skipped_count`, add a " already applied (ledger), skipping" note); if recorded+checksum-DIVERGED → log WARNING and re-apply (honours the re-run-safe contract, does NOT hard-fail); un-recorded → apply as before. After a CLEAN apply (`$fileHadGenuineError` false — idempotent notes are NOT failures) call `recordMigration()` = `INSERT ... ON DUPLICATE KEY UPDATE` with `[name, time(), checksum]` (positional `?` binding, Workerman\MySQL Connection — no raw PDO). A file with a genuine error is left UNRECORDED so it re-runs next boot. - New private helpers `ensureLedgerTable()`, `loadLedger()`, `recordMigration()` each swallow their OWN exceptions (log-and-continue) so a ledger failure degrades to the historical apply-every-file path, never aborts a run. `isAlreadyAppliedNote()` error-squelch KEPT as the secondary safety net. - Class docblock corrected (removed the false "no migration-tracking table" claim). - `migrations/076_schema_migrations.sql` — header corrected: `@see` now points at `MigrationRunner::run()` (consults AND records, bootstrap-creates, warns+re-applies on divergence), and the rewrite-class guidance now states the runner auto-records (manual INSERT optional). - `tests/Unit/Common/Database/MigrationRunnerTest.php` — added `connectionWithLedger()` helper that handles the new bookkeeping queries inertly; updated the 4 capture/count tests to route through it; added 5 ledger tests: (a) clean apply records row w/ name+md5; (b) recorded+match SKIPPED, not executed; (c) divergence WARNS + re-applies + refreshes checksum; (d) empty-ledger-but-applied transition re-applies safely (idempotent note) + backfills; (e) bootstrap CREATE precedes the read. NB: mock callbacks use `$params = null` (not `array`) because Workerman `Connection::query(...)`'s 2nd arg default is `null` — a typed `array` param throws TypeError under PHPUnit ReturnCallback. Transition safety (documented in a code comment in `run()`): on the current live boxes the table exists but the ledger is EMPTY; the SELECT returns no rows → every file treated as un-recorded → re-applied (safe via each migration's `IF NOT EXISTS` + the duplicate-error squelch) → then recorded. Subsequent boots skip unchanged files. Divergence = WARN + re-apply + refresh (never hard-fail). Verification: `phpunit --filter Migration` 22/22 · full `--testsuite Unit` 5000 tests, 38795 assertions, 5 skipped, 0 failures · `phpstan analyze -c phpstan.neon.dist src/Common/Database/MigrationRunner.php` No errors · `phpcs --standard=PSR12` on both touched files clean. Both callers (`scripts/run-migrations.php`, `bin/phlix migrate`) unchanged. ## Orchestrator — SV-4.9 implemented (2026-07-13, perf-5) - [x] SV-4.9 ledger — impl 1788ad35; REVIEW 3 findings (deploy-safety SAFE); FIX e9a461fe (quiet deploy log + degrade/unrecorded tests + checksum normalize). 27/27 Migration, full Unit 5007/0. DONE. ## Re-audit (perf-5) — SV-2.2/2.3/2.7 - SV-2.2 pool hygiene (PooledMySQLConnection) — **DONE (code, wired; pool_enabled default true).** (a) dirty-txn rollback on defer-release (txPending[cid] set/clear via *Trans(), rollBack before idle push); (b) idle->pop(10.0) timeout→"pool exhausted"; (c) created-- on dead conn (SELECT 1 fail + factory throw); (d) non-coroutine bounded while-poll (no recursion). GAP: 3 core behaviors coroutine-only → UNTESTED in CI (on-box owed). Minor: txPending only via *Trans() family (raw "BEGIN" SQL wouldn't flip — codebase uses *Trans, low risk). - SV-2.3 relay backpressure (RelayConsumer) — **PARTIAL.** DONE: hub→local onData (send()===false→pauseRecv+drain→resumeRecv) + HTTP_RESPONSE withFile path (proper while loop). NOT DONE: local→hub direction — sendDataFrame:1712-1720 / sendFrame:1688-1697 IGNORE send() return (fire-and-forget, unbounded queueing = the exact S-F36 large-media case); AND onLocalData:1596-1600 still `do…while` (emits empty DATA frame on zero-length read). No pause/resume test (MockConnection::send always true). → COMPLETE: check send() in sendDataFrame/sendFrame→pauseRecv localConnections[$channelId]+resumeRecv on drain; do…while→while; slow-reader local→client test. - SV-2.7 auth status cache (AuthManager) — **PARTIAL.** Cache exists + genuinely consulted (validateAccessToken:898, refreshTokens:837; 5s TTL hrtime) — primary AC met. NOT DONE: invalidateUserStatusCache():231-234 has ZERO callers (revocation = TTL-only; in-worker status change not reflected until TTL); cache UNBOUNDED (refresh-on-read only, no cap/LRU); no cache/revocation tests. → COMPLETE: call invalidate from in-process status-change paths (or document TTL-only + remove dead method); bound/LRU cache; cache-hit/expiry + revocation-within-TTL tests. ### Server queue += SV-2.3(backpressure local→hub), SV-2.7(invalidate+bound). Audits still owed: SV-1.1–1.6 (transcoding), SV-3.3/3.4 (build-outs). ## Reviewer (per-step: SV-4.9) — 2026-07-13 Verified against commit `1788ad35`. Migration suite 22/22 green; phpstan L9 (`-c phpstan.neon.dist`) clean on `MigrationRunner.php`. Both callers wire correctly: `scripts/run-migrations.php:21-22` and `bin/phlix:97` construct the runner with `ConnectionPool::getConnection('mysql')` → the re-keying `PhlixMySQLConnection` subclass, so the positional `[$name, time(), $checksum]` binding in `recordMigration()` is the safe idiom (sequential list + `?` placeholders, no raw PDO/mysqli). `MigrateCommand`'s exit code keys off `errors`, not `applied`, so the changed `applied` semantics (ledger-skipped files no longer listed) do not break the exit contract. **Deploy-safety verdict on the empty-ledger transition: SAFE.** I audited every DML/rewrite statement in `migrations/*.sql` for re-run safety under the first-post-deploy apply-all: - `004_admin_user_flag.sql:28` UPDATE users — guarded by `AND NOT EXISTS (... is_admin=1)`, no-op on replay. - `043_media_items_canonical_key.sql:51` / `050_media_items_sort_indexes.sql:125,129` UPDATE — WHERE `... IS NULL` + re-derive identical values; idempotent. - `051_media_item_genres_join_table.sql:116` INSERT IGNORE — PK-guarded. - `068_metadata_ratings_source_enum.sql` — the `source='user'` UPDATE is a no-op on replay; the DROP INDEX → MODIFY → re-ADD UNIQUE sequence net-nulls cleanly within the migration (or is squelched); the aggregate backfill re-derives identical values. Critically, this transition path is byte-identical to the pre-SV-4.9 every-boot apply-all these migrations already survived — it introduces no NEW re-run risk, then records + skips thereafter. No migration is unsafe to re-run. The runner's bootstrap CREATE matches `076`'s table definition exactly (name/applied_at/checksum, PK name, InnoDB utf8mb4) — no schema drift. Degrade path is genuine: `ensureLedgerTable` swallow → `loadLedger` catch → empty map → apply-all; `recordMigration` failures swallowed per-file; `076` itself creates the table in the file loop. No crash, no skipped migration. Findings: 1. **[MEDIUM — deploy-log noise regression, contradicts the documented design intent]** `src/Common/Database/MigrationRunner.php:176` pushes a per-file note `" already applied (ledger), skipping"` into `notes[]` for EVERY ledger-skipped file, but `isAlreadyAppliedNote()` (`:326-332`) recognises only `'Duplicate column name'` / `'Duplicate key name'` / `'check that column/key exists'` / `'already exists'` — it does NOT match the string `"already applied"`. Both callers print any note that fails `isAlreadyAppliedNote` IN FULL (`scripts/run-migrations.php:37-39`, `src/Console/Commands/MigrateCommand.php:59-61`). Net effect: once the ledger is populated (steady state — i.e. every deploy after the first), the migration run prints ~79 lines `note: NNN_xxx.sql already applied (ledger), skipping` in full AND the `"N statement(s) skipped (already applied)"` summary line. This is exactly the per-deploy echo the `skipped_count` collapse — documented at `:108-115` ("render a single '...skipped...' summary line instead of echoing each on every deploy") — was designed to prevent. Fix: either do not add the per-file note to `notes[]` for a ledger skip (rely on `skipped_count` alone), or make the ledger-skip note recognised by `isAlreadyAppliedNote()` so the callers collapse it. Not deploy-unsafe, but it defeats the stated purpose of the skip-count mechanism and makes every steady-state deploy log read as if 79 things happened. 2. **[LOW — test gap vs review criterion 2/7]** The 5 new tests cover record-after-apply, skip-on-match, divergence-warn+reapply, empty-ledger transition, and bootstrap-before-select. But NO test asserts that a migration raising a GENUINE (non-idempotent) error is left UNRECORDED so it re-runs next boot (`if (!$fileHadGenuineError)` at `:227`), nor that a ledger READ failure degrades to apply-all (`loadLedger` catch at `:274-279`). Both behaviours are correct by inspection, but the "partially applied then errored → unrecorded / re-run safe" contract (criterion 2) and the degrade path are unverified by tests. 3. **[LOW — observation, self-healing]** The checksum is `md5()` over the ENTIRE file including header comments (`:170`). The `076` rewrite-class protocol explicitly instructs operators to "Document the rewrite in this header." Editing a migration's documentation header AFTER it was applied diverges the checksum → triggers a WARNING + one re-apply on the next boot (`:185-189`). Harmless (migrations are re-run safe) and self-heals (the new checksum is recorded, so it re-applies exactly once), but a mild surprise worth a one-line note in the 076 header (e.g. "editing any byte of an applied migration — including comments — will trigger a one-time re-apply"). ## Orchestrator — SV-4.9 REVIEW (2026-07-13, perf-5): 3 findings (deploy-safety SAFE — empty-ledger re-apply byte-identical to pre-existing apply-all; all migrations re-run-safe, verified) 1. MEDIUM — deploy-log noise: MigrationRunner:176 adds per-file "already applied (ledger), skipping" note but isAlreadyAppliedNote() (:326-332) doesn't match "already applied" → both callers print ~79 full lines every steady-state deploy (defeats note-collapse). Fix: drop the per-file ledger-skip note OR make it match isAlreadyAppliedNote(). 2. LOW — test gaps: genuine-error-left-unrecorded + ledger-read-failure degrade path unverified. 3. LOW — md5 over whole file incl comments → a doc/comment edit triggers a one-time re-apply (benign but avoidable; normalize hash to SQL-only or document). → FIX all 3 (server writer) AFTER SV-4.11 finishes (one writer per repo). ## Implementer — SV-4.11 (2026-07-13): Channel-gate fix LANDED ✅ The adjacent SV-0.4-class bug is fixed. `defaultFetcher()` async branch now gates on `WorkerContext::isEventLoopRunning() && WorkerContext::inCoroutine() && !EventLoopTls::requiresBlockingCurl($url)` (mirrors SV-4.5/S3Client `:284-286`) — was `isEventLoopRunning()` ALONE. Outside a coroutine (getCid()==0: plugin auto-update worker / plain HTTP handler) it now takes `curlFetch()`, so the `Swoole\Coroutine\Channel` in `asyncFetch()` is only ever constructed/`pop()`ed with getCid()>0 — killing the spurious immediate-false "async fetch timed out". Files changed (absolute): - `/home/sites/phlix/phlix-server/src/Plugins/Catalog/PluginCatalogService.php` — gate in `defaultFetcher()` (renamed local to `$useAsync`, added `inCoroutine()` conjunct + S-F12/SV-0.4 comment); async-routing docblock (:407-…) updated to state the mandatory coroutine gate. `asyncFetch`/`curlFetch` bodies untouched. - `/home/sites/phlix/phlix-server/tests/Unit/Plugins/Catalog/PluginCatalogServiceTest.php` — deleted the stale "coroutine-safe (cURL under SWOOLE_HOOK_NATIVE_CURL)" comment; added 3 tests: (1) `test_default_fetcher_uses_blocking_curl_branch_outside_coroutine` (@group network) — asserts inCoroutine() false on main stack and the error is a cURL-path RuntimeException (NOT "async fetch"), proving no Channel; (2) `test_async_fetch_wakes_on_success_callback_inside_coroutine` — inside `Swoole\Coroutine\run`, reflection-invoke `asyncFetch` with a mock Workerman client firing `success` → returns the body; (3) `test_async_fetch_times_out_cleanly_inside_coroutine` — in-coroutine, no callback → RuntimeException "async fetch timed out" AFTER actually waiting ≥900ms (clean timeout, not the immediate false-timeout bug). Verification: `phpunit --filter PluginCatalog` = 31 tests / 87 assertions OK (timeout test waited full 1s via Swoole Timer). Full `--testsuite Unit` = 5002 tests OK (4 warnings / 5 skipped all pre-existing TranscodeManager). `phpstan analyze -c phpstan.neon.dist` clean on both files. `phpcs --standard=PSR12 src/...PluginCatalogService.php` clean; the test-file phpcs "not in camel caps" + one fixture line-length are the file's pre-existing snake_case convention (new methods follow it). SV-4.11 Acceptance met. ## Orchestrator — SV-4.11 DONE (2026-07-13, perf-5) - [x] SV-4.11 — docblock+async were done; FIX cff88617 changed defaultFetcher gate to isEventLoopRunning()&&inCoroutine()&&!requiresBlockingCurl (mirrors SV-4.5/S3Client), killing the spurious async-fetch-timeout; tests: blocking-outside-coroutine + async-wake-in-coroutine + clean-timeout(≥900ms). Full Unit 5002/0, phpstan clean. Accepted w/o re-review (verbatim reviewer fix on an already-reviewed pattern, both branches tested). ## Fixer — SV-4.9 (3 review findings) — 2026-07-13 (perf-5) Fixed all 3 SV-4.9 review findings on top of impl 1788ad35. Finding 1 (MEDIUM — deploy-log noise regression): `MigrationRunner::run()` no longer pushes a per-file " already applied (ledger), skipping" note into `notes[]` for a ledger skip — it only bumps `skipped_count`. Both callers print any note failing `isAlreadyAppliedNote()` in full, and that string was never matched, so steady-state deploys were echoing ~79 note lines. Now the callers render only the single "N statement(s) skipped (already applied)" summary line. `notes` docblock updated. Callers unchanged (runner-side fix). Verified by new test (h) `testSteadyStateSkipEmitsNoPerFileNotes` (2 recorded files → 0 executed, 0 notes, skipped_count=2) + updated test (b) assertion (notes now []). Finding 2 (LOW — test gaps): added (f) `testGenuineErrorLeavesMigrationUnrecorded` — a genuine non-idempotent error leaves the file UNRECORDED (no INSERT), so it re-runs next boot; (g) `testLedgerReadFailureDegradesToApplyAll` — the ledger SELECT throwing degrades to the historical apply-all path (both files applied, no crash). Finding 3 (LOW — checksum over whole file): chose the PREFERRED normalize option (low-risk). New private `MigrationRunner::checksum()` strips full-line `--`/`#` comments + per-line trailing whitespace before `md5()`, so a doc/comment-only edit to a `.sql` no longer flips the checksum → no spurious one-time re-apply. Normalization is narrow and CANNOT mask a real SQL change (only entirely-comment lines and trailing whitespace are removed; inline trailing `-- ...` on a statement line and any SQL token change are preserved). 076 header updated to document this. Verified by (i) `testCommentOnlyEditDoesNotDivergeChecksum` (comment/ws-only edit → still skipped) + (j) `testRealSqlEditStillDivergesChecksum` (INT→BIGINT → re-applied). Also fixed a pre-existing phpstan `new.resultUnused` in `testConnectionProviderIsNotCalledAtConstruction` (assign + assertInstanceOf) at user request. Deploy-safety preserved: re-run-safe (failed migration unrecorded), empty-ledger transition, and swallow-and-degrade fallback all intact.

X8 UNBLOCK (small, producer-first): (1) MusicController::formatTrack/getTrack must MINT a signed `/media/{id}/stream` URL (like AudiobookController:392 `SignedUrl::fromEnv()->mint`) — track row id IS the media_items id, and generic GET /media/{id}/stream (HttpHandler::serveMediaStream, wired :148, Range-safe + signed/session auth) already serves it. ~5 lines unblocks direct-play.

GAPS: no tests (negotiation + audio-filter mandated); confirm direct-play playback-info (MediaItemController/WebPortalRouter) also reads capabilities (only TranscodeController entry confirmed); single-audio-track selection only. → TEST + verify playback-info path. - SV-3.4 artwork cache — **DONE.** ArtworkStorage download+resize [185,342,500,780]+orig; HttpHandler::serveArtwork (route /api/v1/artwork/{itemId}?size=, signed/session, ETag+Cache-Control immutable, withFile); poster_srcset emitted (MediaItemShaper:68-91) + contract test. GAP: no ArtworkStorage download/resize unit test. NOTE: ArtworkController.php is dead/duplicate (unregistered) → §6 removal candidate. Minor: on-box confirm ArtworkStorage DI live. ### Server queue reprioritized: SV-4.9-fix(running) → **X8 music-stream producer (SMALL, unblocks UI-3.6)** → SV-1.10(login store) → SV-0.8(findPathsMap) → SV-4.10 → SV-0.9 → SV-2.3 → SV-2.7 → SV-4.4 → SV-3.1 f/g/h → SV-3.6 → SV-4.13-finish → SV-4.2-disconnect → build-out completions (SV-3.2 gapless, SV-3.3 tests) → test top-ups. Audits owed: SV-1.1–1.6 (spawning 1.1-1.3). ## Re-audit (perf-5) — SV-1.1/1.2/1.3 - SV-1.1 HDR tone-map memoize — **PARTIAL.** Probe storm KILLED: FfmpegRunner::$probeMemo keyed path:mtime (≤1 probe/file/worker); decision resolved once in computeHlsParams (require_hdr_tone_map) threaded via segment_params. AC "≤1 probe" MET. GAPS: (1) mig 073 media_streams color cols are WRITE-ONLY — ensureHlsJob:367 ALWAYS live-probes, never reconstructs decision from persisted cols (so "0 probes if scanned" never achieved, always exactly 1). (2) buildSegmentCommand:1512-1518 re-derives via getToneMappingProfile→probe (relies on memo, not threaded flag+filter string). (3) no probe-count/session test. → LOWER PRIORITY completion (read from media_streams to reach 0 probes + thread filter string + probe-count test). - SV-1.2 non-probe ffmpeg coroutine — **DONE (minor).** thumbnails/subtitle/trickplay/hwaccel-probe route via runCoroutineAware{Command,ShellExec} (Coroutine\System::exec under cid). MINOR: detectLibplacebo:508 + getVersion:1071 still raw shell_exec (libplacebo reachable under segment coroutine, cached per-worker); wrapper coroutine-path test gap. → LOW top-up. - SV-1.3 chapter-thumb+trickplay background job — **NOT-DONE (INERT, PROD-BREAKING).** MediaAssetJobStore/MediaAssetWorker/config supervision all real, BUT MediaScanner autowire (MediaServicesProvider:287-302) doesn't name mediaAssetJobStore (param 11) → null → enqueue guard (MediaScanner:1340) never true → nothing enqueued. WORSE: inline generation DELETED → chapter thumbnails + trickplay NEVER generated in prod. → COMPLETE: ->constructorParameter('mediaAssetJobStore', get(MediaAssetJobStore::class)) + scanner enqueue test + prod-wiring test. ### ⚠️ RECURRING DI LANDMINE (consolidate): PHP-DI skips optional defaulted ctor params unless NAMED. Produced 3 inert features: loginRateLimitStore (SV-1.10/AuthServicesProvider), mediaAssetJobStore (SV-1.3/MediaServicesProvider MediaScanner), similarityJobStore (SV-2.9/MediaServicesProvider MediaScanner param 12). → ONE consolidated "wire missing DI" fix agent: add ->constructorParameter for all three + audit every provider for other `?Type $x=null` params that should be live + prod-wiring tests. (High value: SV-1.3 no-thumbnails + SV-1.10 unbounded-login are prod-impacting.) ### Audits owed (deferred, lower priority): SV-1.4/1.5/1.6 (tonemap graph zscale/libplacebo + subtitle burn-in — visual, on-box verify needed). ## Implementer — X8 music-track stream producer (unblocks UI-3.6) — 2026-07-13 **DONE ✅** (commit: music: X8 mint signed track stream_url + audio MIME). Files changed: - `src/Server/Http/Controllers/MusicController.php` — `formatTrack()` now mints a signed `stream_url` = `SignedUrl::fromEnv()->mint('/media/' . $trackId . '/stream')` (added `use Phlix\Auth\SignedUrl;`). The track row id IS the `media_items` id, so the generic Range-safe `GET /media/{id}/stream` (`HttpHandler::serveMediaStream`) already serves it. `getTrack()` returns `formatTrack()` output, so it inherits `stream_url` — no separate edit needed. Emitted shape: `"stream_url": "/media//stream?exp=&sig="` (null when id is blank). → **AC1 (unblock direct-play) MET.** - `src/Server/Workerman/HttpHandler.php` — renamed `videoMimeFor()` → `streamMimeFor()` (single call site updated) and added audio types: mp3→audio/mpeg, m4a→audio/mp4, aac→audio/aac, flac→audio/flac, ogg/oga→audio/ogg, opus→audio/opus, wav→audio/wav (video mappings retained). `serveMediaStream()` uses it for the track Content-Type. → **AC2 (audio MIME) MET.** Audio previously served as `application/octet-stream` (would not play). Warnings cleanup (per follow-up request — phpunit + phpcs, on THIS changeset): - Fixed pre-existing phpunit **PHP Warning** "Undefined array key color_space/color_transfer/ color_primaries" (TranscodeManager.php:2215-2218). Root cause = TEST mock artifact: bare `FfmpegRunner` mock returns null for `extractColorMetadata()` (which in production always returns a full shape). Fixed in `tests/Unit/Media/Transcoding/TranscodeManagerTest.php` `manager()` helper via new `stubColorMetadata()` — NOT in production (phpstan proves the keys always exist; a prod `?? ''` guard would be a phpstan error). Full Unit suite now emits 0 PHP warnings. - Fixed phpunit **deprecation** "Calling static trait method TranscodeFileServer::parseRange is deprecated" (surfaced by the new serveMediaStream test). Extracted the pure range parser to a new final class `src/Server/Http/Controllers/ByteRangeParser.php` (`::parse()`); the trait's `parseRange()` now delegates to it (API preserved for mixing-in consumers); `HttpHandler` calls `ByteRangeParser::parse()`. No external static-on-trait call remains. Tests added: - `MusicControllerTest::testGetTrackEmitsSignedStreamUrl` — asserts path `/media/track-42/stream` + `exp`/`sig` that verify via `SignedUrl::fromEnv()`. - `HttpHandlerServeMediaStreamTest` (new) — serves a `type='track'` .flac media_item over a signed URL: 200 + `Content-Type: audio/flac`, Range 206, unsatisfiable 416, + a data-provider MIME map test over `streamMimeFor` (all 7 audio + retained video + unknown). - `ByteRangeParserTest` (new) — 9 cases incl. trait-delegation parity via `HlsController::parseRange`. Verification: - `phpunit` targeted (Music|MediaStream|ByteRangeParser|TranscodeManager|HlsController): 152 tests OK. - full `--testsuite Unit`: **5030 tests / 38855 assertions / 5 skipped / 0 failures / 0 errors / 0 PHP warnings / 0 deprecations**. - `phpstan analyze -c phpstan.neon.dist`: clean on all changed files (the 2 remaining errors in TranscodeManagerTest at ~1576/1722 are PRE-EXISTING on HEAD — confirmed via stash — untouched by me). - `phpcs --standard=PSR12`: **clean (exit 0) on the entire X8 changeset.** **phlix-contracts:** NO repin needed. `stream_url` matches the existing AudiobookController convention; no contract test forced a schema change. (Follow-up flag: if a `phlix-contracts` track schema is later added, it should carry `stream_url` — do it in a dedicated repin.) **OUT OF SCOPE (flagged, NOT done):** the repo-wide `phpcs src/` run reports **202 pre-existing `Generic.Files.LineLength.TooLong` warnings across 82 unrelated files** — none in the X8 changeset. These are known/accepted style debt (CI "Server Component Tests" red via these → admin-merge pattern). Reformatting 82 unrelated files would bury the functional change in a risky, unreviewable diff → recommend a dedicated formatting-only commit rather than bundling into X8. Also out of scope per the step: gapless/crossfade wiring (`buildGaplessSegmentCommand` inert) and codec-transcode fallback (rides SV-3.3). ## Orchestrator — X8 music-stream producer DONE (2026-07-13, perf-5) - [x] X8 producer — 1b760ad7. REVIEW NO FINDINGS (signed-URL contract verified: same signer/path/exp both sides, correct media_items id, MIME rename complete, ByteRangeParser behavior-preserving; 147/147). DONE. MusicController::formatTrack mints signed stream_url `/media/{trackId}/stream?exp&sig` (getTrack/listTracks/nowPlaying inherit); HttpHandler videoMimeFor→streamMimeFor + audio MIME (mp3/m4a/aac/flac/ogg/opus/wav). Bonus: fixed color_space test-mock warnings, extracted ByteRangeParser (killed parseRange deprecation) → full Unit 5030/0, 0 warnings/deprecations. phlix-contracts repin NOT needed (stream_url matches audiobook convention). REVIEW pending. UNBLOCKS UI-3.6. - NOTE: 2 pre-existing phpstan errors in TranscodeManagerTest ~1576/1722 (on HEAD, not from X8); 202 pre-existing repo-wide phpcs LineLength warnings (82 files) — dedicated formatting commit candidate, not folded into functional work. ## Reviewer (per-step, X8 music-stream producer, commit 1b760ad7) — 2026-07-13 NO FINDINGS Verified (read-only): - CONTRACT: `formatTrack` mints `SignedUrl::fromEnv()->mint('/media/'.$trackId.'/stream')` → `/media/{id}/stream?exp&sig`. `serveMediaStream` matches `^/media/(?P[^/]+)/stream$` on `$wr->path()` (query-less) and `isMediaStreamAuthorized` verifies with the SAME signer over the SAME path via `SignedUrl::verify($wr->path(), exp, sig)`. `canonicalResource('/media/{id}/stream')` returns the exact path (only /hls|/dash collapse), so both sides HMAC the identical `VERSION\n{path}\n{exp}` message. No path/scheme/exp mismatch → music plays will NOT 401. - ID CORRECTNESS: track rows come from `MusicLibraryManager::getTracks` → `ItemRepository::getByType` → `SELECT * FROM media_items WHERE type='track'`; `track['id']` IS the media_items PK, so `findById($m['id'])` in serveMediaStream resolves. Not a music-domain id. - AUTH/SECURITY: signed URL is bound to the exact per-track path + bounded exp (TTL from PHLIX_SIGNED_URL_TTL, default 6h); authorizes only that id, no over-grant; no secret/token leakage; JSON music endpoints (mint site) are behind the auth group, so only authed users obtain the URL — matches the AudiobookController convention. - MIME: `streamMimeFor` returns correct `audio/*` for mp3/m4a/aac/flac/ogg/oga/opus/wav; retained video mappings; sane `application/octet-stream` fallback. Rename `videoMimeFor`→`streamMimeFor` is complete — `grep -rn videoMimeFor src/ tests/` finds ZERO stale callers. - ByteRangeParser EXTRACTION: `parse()` body is a verbatim move of the old trait logic; `TranscodeFileServer::parseRange` now delegates (API preserved for trait consumers like HlsController); 206/416/suffix/over-long-clamp semantics unchanged. ByteRangeParserTest asserts trait-delegation parity. - NO REGRESSION: `formatTrack` ADDS `stream_url` (null when id blank) without dropping/renaming other fields; `serveMediaStream` unchanged except the MIME helper name + `ByteRangeParser::parse` call. - TESTS genuinely exercise the contract: MusicControllerTest::testGetTrackEmitsSignedStreamUrl does a real mint→`SignedUrl::fromEnv()->verify()` round-trip on `/media/track-42/stream`; HttpHandlerServeMediaStreamTest drives the actual `serveMediaStream` via the signed-URL (userId=null) auth path → 200 audio/flac, 206 Range, 416 unsatisfiable, + a 10-case MIME data-provider. - Suite: `phpunit --filter 'Music|MediaStream|ByteRangeParser'` = 147 tests / 362 assertions OK; phpstan L9 on all 4 changed src files = No errors. ## Implementer — DI landmine consolidation (SV-1.10 + SV-1.3 + SV-2.9 wiring) — 2026-07-13 Root cause (per the RECURRING DI LANDMINE note): PHP-DI skips optional defaulted ctor params during autowiring unless NAMED via `->constructorParameter(...)`. Three green-tested features were INERT in prod because their store dependency defaulted to null. All three wired; a provider-wide sweep run. Files changed: - `src/Common/Container/Providers/AuthServicesProvider.php` — SV-1.10: import `DbLoginRateLimitStore`; added `->constructorParameter('loginRateLimitStore', get(DbLoginRateLimitStore::class))` to the `AuthManager` autowire (~:176). Store is autowirable (ctor = `Connection $db` [bound in CoreServicesProvider] + defaulted `int $windowSeconds`). Prod now uses the shared bounded DB store (login_rate_limit table, migration 074 — confirmed present in `migrations/074_login_rate_limit.sql`) instead of the unbounded per-worker static array. - `src/Common/Container/Providers/MediaServicesProvider.php` — SV-1.3 + SV-2.9: added `->constructorParameter('mediaAssetJobStore', get(MediaAssetJobStore::class))` and `->constructorParameter('similarityJobStore', get(SimilarityJobStore::class))` to the `MediaScanner` autowire (~:303-321). MediaAssetJobStore was already registered (factory, config queue dir); registered `SimilarityJobStore::class => autowire()` (~:590) since it had NO binding — its enqueue in MediaScanner was therefore doubly dead (null + unregistered). - `src/Auth/AuthManager.php` — bounded the static in-memory FALLBACK store (only reachable when no DB store is injected, i.e. tests/legacy): new const `RATE_LIMIT_FALLBACK_MAX_IPS = 10000` + private `boundFallbackStore()` (sweep-expired-then-evict-oldest) called before inserting a new IP in `recordFailedAttempt()`. Prevents unbounded growth if the fallback is ever exercised in a resident worker. No change to the store-wired path. Dual entrypoints: both `public/index.php` and `start.php` build via `ContainerFactory::create()` using `defaultProviders()`, so the provider edits cover FPM/CI + Swoole. Confirmed. Tests added (all green): - `tests/Unit/Common/Container/ContainerFactoryTest.php` — 3 PROD-WIRING tests resolving the consuming class from the REAL container (`containerWithMockedDb()`): AuthManager.loginRateLimitStore is a DbLoginRateLimitStore; MediaScanner.mediaAssetJobStore is a MediaAssetJobStore; MediaScanner .similarityJobStore is a SimilarityJobStore. These FAIL without the constructorParameter wiring. - `tests/Unit/Media/Library/MediaScannerTest.php` — behaviour: a scan with both stores wired enqueues 1 media-asset job (only the chapter-capable .mkv, not the .avi) + 2 similarity jobs (per new item); negative test: unwired stores enqueue nothing. - `tests/Unit/Auth/DbLoginRateLimitStoreTest.php` (new) — behaviour: allow-when-no-record; throw-when-over-limit; sweep-expired-on-check; recordFailedAttempt upsert + bounded LIMITed sweep; clear deletes the row. Sweep of all 14 providers (script reflected every `autowire()` class ctor for `?ObjectType $x = null` params not named). OTHER unwired optional deps found — NONE wired here (see "SV-2.9 remaining" + report): - Logger-typed params (`?LoggerInterface`/`?StructuredLogger`) across BackupManager, WebhookService, WebAuthnManager, FuzzyMatcher, LibraryMetadataMatcher, LibraryScanWorker, MediaAssetGenerationJob, BackgroundDetectorWorker, Movie/SeriesMetadataResolver, ThemeMusicResolver — NOT bugs (each self-defaults to a NullLogger or a channel logger internally). - Fine (intentional/default-constructed): Movie/SeriesMetadataResolver `$fieldResolver` (PriorityFieldResolver default-constructed by design, per existing comment). - FLAGGED as genuine additional instances of the SAME landmine but NOT fixed (out of this step's tight scope / not clearly-safe — each needs its own audit/cycle): * `LibraryMetadataMatcher::$artworkStorage` (SV-3.4) — local artwork caching is INERT (null-gated no-op at `cacheArtworkLocally`). NOT wired: `ArtworkStorage::downloadAndStore()` uses BLOCKING `curl_*`, and the matcher is reachable from the interactive HTTP `MediaMatchController` → wiring it would put blocking I/O on an HTTP handler (CARDINAL rule). Belongs in SV-3.4's cycle (move the download off the hot path / confirm Swoole curl hook). * `AuthManager::$providerManager` — external-provider login (`loginWithProvider`) always throws "ProviderManager is not configured", BUT `loginWithProvider` has ZERO callers in src/ (the real SSO flow goes through AuthProviderController→ProviderManager directly), so it is dead-from-AuthManager, not a prod-impacting inert feature. Flag only. * `WatchHistory::$recommendationService` — "because-you-watched" recompute on watch-completion is inert. NOT wired: markComplete runs in the HTTP watch path → inline O(N) recommendation compute would violate the no-heavy-inline rule; the correct fix is a background job (like SV-2.9). Flag. * `MediaScanner::$trailerFinder` — local-trailer discovery inert. NOT wired: TrailerFinder has NO DI binding anywhere (needs registering first); scan-only. Flag. * Lower-impact flags: `PlaybackController::$playToManager` (DLNA play-to), `HubClient:: $portForwardService` (NAT), `SmartPlaylistRefreshHandler::$collectionManager/$collectionRepo`, `BackupManager::$auditLogger` — each inert when null; own-cycle candidates. SV-2.9 remaining beyond wiring: the store is now live and the enqueue fires, BUT there is NO consumer — no SimilarityWorker/queue-drain process and no `config/similarity_jobs.php` (unlike SV-1.3 which has MediaAssetWorker + config + supervision). So jobs accumulate in `/tmp/phlix_similarity_jobs` undrained. A follow-up must add a SimilarityWorker (mirroring MediaAssetWorker) + config + worker supervision, or the enqueue is a leak. Flagged for SV-2.9's build-out cycle. Verification: `phpunit tests/Unit/Auth/DbLoginRateLimitStoreTest.php ContainerFactoryTest MediaScannerTest` = 104/911 OK; full `--testsuite Unit` = 5040 tests, 0 fail (5 skip); phpstan L9 on all changed src + test files = No errors; `phpcs --standard=PSR12 src/` = 0 errors (only pre-existing LineLength warnings on untouched lines). ## Orchestrator — DI-wiring consolidated fix (2026-07-13, perf-5): 3f56a7b7 - [~] Wired loginRateLimitStore (AuthServicesProvider:176), mediaAssetJobStore + similarityJobStore (MediaServicesProvider:303/318) + registered SimilarityJobStore binding (:590); bounded static login fallback (RATE_LIMIT_FALLBACK_MAX_IPS=10000). Dual-entrypoint confirmed. Prod-wiring tests (real container) + behavior tests. Full Unit 5040/0, phpstan clean. REVIEW pending (verify: login now does a DB call → coroutine-safe/no blocking/latency? scan enqueue no regression?). ### ⚠️ DI-landmine is BROADER (sweep across 14 providers) — more inert features from `?Type $x=null` unnamed: - SV-2.9 similarityJobStore now enqueues but NO consumer (no SimilarityWorker/config/supervision) → /tmp/phlix_similarity_jobs accumulates undrained (DISK LEAK). → SV-2.9 needs worker+config+supervision (mirror MediaAssetWorker). - ★ SV-3.4 artwork cache likely INERT: LibraryMetadataMatcher::$artworkStorage nullable-defaulted → PHP-DI skips → cacheArtworkLocally no-op → local artwork NEVER downloaded (contradicts earlier SV-3.4 DONE). NOT wired b/c ArtworkStorage::downloadAndStore uses BLOCKING curl on an HTTP-reachable matcher. → SV-3.4 completion: make artwork download coroutine-aware/async THEN wire. (VERIFY poster_srcset isn't pointing at never-generated variants.) - Dead/low: AuthManager::$providerManager (loginWithProvider 0 callers), WatchHistory::$recommendationService (needs bg job not inline), MediaScanner::$trailerFinder (TrailerFinder has NO binding), PlaybackController::$playToManager, HubClient::$portForwardService, SmartPlaylistRefreshHandler::$collection*, BackupManager::$auditLogger. Logger params self-default (NOT bugs). ## Reviewer (per-step, DI-wiring fix, commit 3f56a7b7) — 2026-07-13 1. src/Auth/DbLoginRateLimitStore.php:166-169 (`cleanupExpiredEntries()`) — `DELETE FROM login_rate_limit WHERE reset_at <= ? LIMIT ?` binds BOTH params as STRINGS: `[(string) time(), (string) self::CLEANUP_BATCH_SIZE]`. The project DB layer (`PhlixMySQLConnection`/`PooledMySQLConnection`) uses EMULATED prepares with type-aware binding: `pdoParamType()` maps a PHP string to `PDO::PARAM_STR`, which PDO QUOTES → the SQL becomes `LIMIT '100'` → MySQL error 1064 (syntax error). This is the exact failure the `PhlixMySQLConnection` binding override was written to prevent ("integers stay unquoted so LIMIT ?/OFFSET ? work" — every other live `LIMIT ?` call in src/ passes an INT, e.g. Recorder.php:399, SimilarityService.php:147, MetricsRepository.php:312). WHY IT MATTERS: this commit is the FIRST time the store runs live — it wires `loginRateLimitStore` onto the login path (AuthManager::recordFailedAttempt → store->recordFailedAttempt → cleanupExpiredEntries). `cleanupExpiredEntries()` fires on EVERY failed login. The thrown `PDOException` is not caught → it propagates out of `AuthManager::login()`, turning every failed-credential attempt into a 500 instead of a clean auth failure, AND expired rows are never swept (table bloat). The store was inert before this commit so the latent bug was dormant; wiring it activates it. The new `DbLoginRateLimitStoreTest` does NOT catch this because it `createMock`s the Connection and stubs `query()` — the real emulated-prepare binding is never exercised (the recurring "green mocked test hides broken DB SQL" landmine). FIX: pass the LIMIT (and ideally the timestamp) as INTEGERS, not strings — `[time(), self::CLEANUP_BATCH_SIZE]` — so `pdoParamType()` binds them PARAM_INT and the LIMIT stays unquoted. (The `reset_at <= ?` string alone would coerce fine numerically, but the `LIMIT` string is a hard 1064.) Add a non-mocked/integration assertion that the store's cleanup runs against the real connection binding, or at least assert the params passed to `query()` for the LIMIT slot are int. ## Fixer — SV-DI LIMIT-bind bug (2026-07-13): FIXED - src/Auth/DbLoginRateLimitStore.php cleanupExpiredEntries(): removed the `(string)` casts → `[time(), self::CLEANUP_BATCH_SIZE]` (both int). Was `LIMIT '100'` under emulated prepares → MySQL 1064 on EVERY failed login (recordFailedAttempt→cleanup). reset_at is INT UNSIGNED (mig 074) so both params are correctly int. Full-file audit: no other numeric-param-as-string sites (all other calls pass $ip=string [VARCHAR] and $resetAt/$now=int correctly). - Regression guard: added test_cleanup_sweep_binds_numeric_params_as_int — captures the DELETE...LIMIT params and asserts is_int() on both (LIMIT slot + reset_at threshold); a re-introduced (string) cast goes red despite the DB mock. phpunit --filter DbLoginRateLimitStore = 6/6 OK. phpstan L9 (dist) on both changed files = No errors. phpcs src = clean (test file has pre-existing test_snake_case names, file-wide convention). ## Implementer — 2026-07-13 — SV-3.4 sub-step 1/7 (ArtworkStorage non-blocking download) - `src/Media/Storage/ArtworkStorage.php`: `downloadToTemp()` now dispatches via `shouldUseBlockingDownload()` (reuses shared `Common\Runtime\WorkerContext::isEventLoopRunning()/inCoroutine()` + `Common\Http\EventLoopTls::requiresBlockingCurl()`) → async path `downloadToTempAsync()` uses `Workerman\Http\Client` + `Swoole\Coroutine\Channel` cooperative wait (mirrors MetadataHttpClient; no busy-spin, 30s timeout via Channel::pop), blocking fallback `downloadToTempBlocking()` keeps the original cURL (CLI/scan/test + https-under-Swoole TLS stall) and now fclose()s the file handle. Failure = clean `\RuntimeException` (caller `cacheArtworkLocally` already try/catches → never bubbles to HTTP handler). GD/resize + public signatures unchanged. - Tests: `tests/Unit/Media/Storage/ArtworkStorageTest.php` (+ fixture `TestableArtworkStorage.php`): async success writes temp + generates variants; non-worker context selects blocking; async error / non-200 → clean RuntimeException, no partial dir. phpunit --filter ArtworkStorage = 5 tests / 22 assertions OK; phpstan L (dist) 3 files = No errors; phpcs PSR12 3 files = clean. - Wiring note: ArtworkStorage stays `autowire()` in MediaServicesProvider (no ctor change) — next sub-step can wire LibraryMetadataMatcher::$artworkStorage without a blocking-I/O CARDINAL violation. ## Implementer — 2026-07-13 — SV-3.4 sub-steps 2+3/7 (wire artworkStorage into matcher + config-drive storage dir) - SUB-STEP 2 (kill DI landmine): `MediaServicesProvider.php` LibraryMetadataMatcher autowire (~:397) + `->constructorParameter('artworkStorage', get(ArtworkStorage::class))` — field was null (PHP-DI skips `?ArtworkStorage=null`) so `cacheArtworkLocally()` was a no-op; now local artwork is downloaded/resized + `poster_srcset`/local `poster_url` persisted. Safe post sub-step-1 (download now non-blocking). - SUB-STEP 3 (config-drive dir): new `config/artwork.php` (`storage_path`, env `ARTWORK_STORAGE_PATH`, default `/var/artwork`) sourced in `config/server.php` (`'artwork' => require ...`); registered `'artwork.storage_path'` factory (reads app.config + @include fallback, /var/artwork default) and `ArtworkStorage::class => autowire()->constructorParameter('storageDir', get('artwork.storage_path'))`. mkdir -p behavior already in `ensureItemDirExists()`. - Tests: ContainerFactoryTest +2 prod-wiring tests (matcher.artworkStorage is ArtworkStorage; storageDir honours config); new LibraryMetadataMatcherArtworkTest (wired → LOCAL srcset/poster_url, not TMDB CDN; unwired → TMDB url stays, no srcset). Dual entrypoints: both index.php + start.php build via ContainerFactory::create() using the shared providers → change propagates to both (confirmed). - Verify: phpunit --filter "LibraryMetadataMatcher|ArtworkStorage|ContainerFactory" = 65/65 OK; tests/Unit/Common/Container = 55/55 OK (real-container matcher resolve doesn't throw); phpstan L9 (dist) 5 files = No errors; phpcs PSR12 src+config+new test = clean (only pre-existing LineLength warns off my lines + ContainerFactoryTest's file-wide test_snake_case convention my 2 methods follow). ## Reviewer (per-step, SV-3.4 sub-steps 1-3, commits e2abc09e + ac96e287) — 2026-07-13 (perf-7) 1 LOW finding + 1 informational note (not blocking). Core sound: DI landmine genuinely killed (prod-wiring test resolves from a REAL container, not mock-only); async dispatch mirrors the proven MetadataHttpClient gate exactly (real runtime probes, not an always-false-guard-class bug); 30s bounded Channel timeout; fclose leak fixed + no partial dirs on error; dual entrypoint mirrored (both build via ContainerFactory::create()); poster_srcset correctness asserted both wired (LOCAL, not TMDB CDN) and unwired (fallback, no crash); config-drive dir confirmed. Suites reproduce green at HEAD (65/65 + 55/55 targeted; phpstan/phpcs clean). FINDING 1 (LOW): `MediaServicesProvider.php:627` — the defensive `@include` fallback for `'artwork.storage_path'` uses 5× `../` (resolves to a non-existent path one level ABOVE the repo root), should be 4× `../` (matches the correct `theme_music` include at :129). Dead in practice — the primary `app.config` path is populated by both real entrypoints — but the fallback silently no-ops instead of reading config/artwork.php, so an env-only ARTWORK_STORAGE_PATH override would be lost IF that path were ever exercised. Same pre-existing bug also present in 4 sibling factories (marker_detection/media_asset_jobs at :496/514/545/570) — fix all 5 while in there. INFORMATIONAL (no fix needed): TMDB https downloads still block via cURL under the Swoole event loop (EventLoopTls::requiresBlockingCurl() is true for https — the project's documented, accepted tradeoff; identical to the sibling MetadataHttpClient already on the same match path). Not a regression. → Fix agent spawned for finding 1. ## Fixer — SV-3.4 review finding — 2026-07-13 (perf-7) Fixed all 5 sites (18b9b659): 5×`../` → 4×`../` in `MediaServicesProvider.php` (:627 artwork.storage_path + pre-existing sibling copies :496/514/545/570 marker_detection/media_asset_jobs). Depth verified empirically via `php -r "realpath(...)"` against the known-good `theme_music` include (:129) as ground truth. Full Unit suite 5050/0 (no regression). phpstan/phpcs clean. ## Reviewer (confirming re-review, SV-3.4 sub-1-3 fix) — 2026-07-13 (perf-7) **NO FINDINGS.** Confirmed commit 18b9b659: scope clean (only MediaServicesProvider.php + worklog); all 5 sites now 4×`../`, independently reproduced via realpath (old 5× resolved to `false`, new 4× resolves to the real config files); targeted 28/28 + full Unit 5050/0 (matches Fixer's claim exactly). **SV-3.4 sub-steps 1-3 are CODE-COMPLETE + review-clean.** Remaining SV-3.4 work: sub-4 (SV-2.5 conditional caching on HttpHandler::serveArtwork — If-None-Match→304 + Last-Modified), sub-6 (phlix-contracts poster_srcset local-path doc/test), sub-7 (serveArtwork route test: signed-URL/session auth, ETag/304, 404, size-validation). sub-5 (dead ArtworkController.php) stays in the §6 removal-confirmation queue, USER SIGN-OFF required, do NOT delete. ## Fixer — SV-3.4 review finding — 2026-07-13 Fixed FINDING 1 (LOW): the `@include` config-fallback path depth in `MediaServicesProvider.php`. - Root cause: the `@include __DIR__ . '/.../config/*.php'` fallbacks used 5× `../`, which from `src/Common/Container/Providers/` resolves to `/home/sites/phlix/config/*.php` — one dir ABOVE the repo root (a non-existent path). `@include` then returns `false`, the branch no-ops, and the cfg array stays `[]`, silently discarding an env-only override (e.g. `ARTWORK_STORAGE_PATH`) whenever that fallback is the exercised path. Correct depth is 4× `../` (Providers→Container→Common→src→repo root, then `/config`), matching the working `theme_music` include at :129. - Depth verified empirically from the `Providers/` dir with `php -r "realpath(...)"`: 5× → bool(false) for all three targets; 4× → the real `/home/sites/phlix/phlix-server/config/{artwork,marker_detection, media_asset_jobs}.php` (all three files exist). Correct include at :129 already uses 4×. - Fixed all 5 occurrences (5× `../` → 4× `../`), no other change to the file: * :627 `artwork.storage_path` factory (the new SV-3.4 site) → config/artwork.php * :496, :514 marker_detection factories (MarkerCandidateStore, IntroDetectionJob) → config/marker_detection.php * :545, :570 media_asset_jobs factories (MediaAssetJobStore, MediaAssetWorker) → config/media_asset_jobs.php - Verification: `php -l` clean; `phpstan analyze -c phpstan.neon.dist src/.../MediaServicesProvider.php` = No errors; `phpcs --standard=PSR12` = 0 errors (2 pre-existing LineLength WARNINGS on untouched lines 537/562); `phpunit --filter "MediaServicesProvider|ContainerFactory" --testdox` = 28/28 OK (incl. "Artwork storage dir is config driven"); full `--testsuite Unit` = 5050 tests, 0 fail, 5 skip (up from the 5040 baseline by the SV-3.4 sub-step tests). No regression. ## Implementer — SV-3.4 sub-4 (conditional caching on serveArtwork) — 2026-07-13 Added the SV-2.5 conditional-GET pattern to `HttpHandler::serveArtwork` (`GET /api/v1/artwork/{id}?size=`), mirroring the reference implementation already in `MediaItemController::getChapterThumbnail` / `PhotoController::getFull` (ETag `md5(mtime.size)` there; here the EXISTING `"-"` hex tag is preserved — the task is additive, not a validator swap). Files changed: - `src/Server/Workerman/HttpHandler.php` (`serveArtwork`, ~:649): * Now derives `$mtime`/`$lastModified` from the same `stat()` that builds the ETag, and emits a `Last-Modified` header on the 200 response (previously only ETag + `Cache-Control: ...immutable`). * Honors conditional GET: `If-None-Match` (authoritative; exact-string compare vs the existing ETag) → 304; `If-Modified-Since` (fallback, only when no `If-None-Match`) → 304 when `strtotime(IMS) >=` file mtime. The 304 carries the ETag + Last-Modified + the same immutable `Cache-Control` but NO body (does NOT call `withFile()`), matching SV-2.5's 304 shape. * ORDERING preserved exactly like SV-2.5's controllers: method-guard → route-match → `?size=` validation → signed-URL/session auth gate → 404 existence check → THEN freshness. A stale/unsigned request can never shortcut to a 304 (verified by tests below). Empty-ETag (stat failure) is guarded so a `stat()` miss never produces a spurious 304. * The existing ETag emission + immutable Cache-Control are unchanged on the 200 path (headers just reorganized into an array so the validators can be shared with the 304 path). - `tests/Unit/Server/Workerman/HttpHandlerServeArtworkTest.php` (NEW, 8 tests, 39 assertions): no conditional headers → 200 + file attached + ETag/Last-Modified/immutable Cache-Control present; matching `If-None-Match` → 304 with `$resp->file === null` and empty `rawBody()`; stale `If-None-Match` → 200 full body; up-to-date `If-Modified-Since` → 304 (fallback path); stale `If-Modified-Since` → 200; `If-None-Match` mismatch beats a fresh `If-Modified-Since` (authoritative) → 200; unsigned request with a would-be-matching validator → 401 (auth before freshness); missing variant file + conditional header → 404 (existence before freshness). Harness mirrors `HttpHandlerServeMediaStreamTest` (mock container → mock `ArtworkStorage::variantPath`, signed-URL mint, reflection-invoke the private method). Verification (at pre-rebase HEAD 18b9b659): - `phpunit --filter HttpHandlerServeArtwork --testdox` = 8/8 OK. - `phpunit --filter HttpHandler --testdox` = 90/90 OK. - `phpunit --testsuite Unit --no-coverage` = 5058 tests, 0 fail, 5 skip (5050 baseline + 8 new). No regression. - `phpstan analyze -c phpstan.neon.dist` on both changed files = No errors (L9). - `phpcs --standard=PSR12` on both changed files = clean (0 errors/0 warnings). Signed-URL note: the artwork auth gate signs the CANONICAL resource (`SignedUrl::signature()` → `canonicalResource()` strips the query), so the `?size=` variant does not affect verify — confirmed empirically; the new 304 branch sits after that gate and does not touch it. STILL OPEN for SV-3.4: sub-6 (phlix-contracts `poster_srcset` local-path doc/test) and sub-7 (a dedicated end-to-end `serveArtwork` route test covering signed-URL/session auth + size-validation + 404 alongside the ETag/304 paths — this sub-4 test already covers the 304/auth-order/404-order slices). ## Reviewer (per-step, SV-3.4 sub-4, commit 3f6c3cc1) — 2026-07-13 (perf-7) **NO FINDINGS.** Ordering verified security-safe by reading top-to-bottom: method-guard → route-match → size validation → signed-URL/session auth → 404 existence → THEN 304 freshness — a 304 can never act as an existence/authorization oracle (directly tested: unsigned+matching-validator → 401 not 304; missing-variant+conditional-header → 404 not 304). ETag compare is strict `===` (no substring/prefix bug class). `strtotime()` on attacker-controlled If-Modified-Since degrades safely to 200 on parse failure. 304 has no body (`file===null`, empty rawBody). Cache-Control consistent 200/304 (actually tighter than the SV-2.5 reference, which diverges public/private). Empty-ETag/stat-failure guarded. Signed-URL canonicalization claim independently verified in `SignedUrl::canonicalResource()` (query stripped before HMAC — `?size=` correctly excluded, pre-existing behavior, untouched by this commit). 8/8 + 90/90 + full Unit 5058/0 reconfirmed; phpstan/phpcs clean. **SV-3.4 sub-4 CODE-COMPLETE + review-clean.** Non-blocking notes (not findings): weak-validator `W/` prefix / `If-None-Match: *` not special-cased (safe direction — never a false 304 — and matches the SV-2.5 reference this mirrors); dedicated tampered-signature auth test deferred to sub-7 per plan. Remaining: sub-6 (contracts doc/test) → sub-7 (dedicated route test). ## Implementer — SV-3.4 sub-6 (phlix-contracts poster_srcset local-artwork docs/fixtures) — 2026-07-13 Updated **phlix-contracts** so the `poster_srcset` contract accurately documents what the server NOW emits after the SV-3.4 DI-landmine fix (sub-1–4): a LOCAL sized-variant srcset pointing at the server's own `/api/v1/artwork/{id}?size=…` route (widths 185/342/500/780 + `original`, served with cache headers per SV-2.5) once artwork is downloaded/resized on match, with a fallback to the `image.tmdb.org` CDN width-swap srcset (or `null`) when no local variant is cached. Producer-side (server) contract catching up so the UI consumer (U-N7) builds against the real shape. Verified against the current server source: `ArtworkStorage::srcset()` (builds the local srcset from `relativePath()` → unsigned `/api/v1/artwork/{id}?size= w` entries), `ArtworkStorage::WIDTHS = [185,342,500,780]` + `ORIGINAL`, `LibraryMetadataMatcher::cacheArtworkLocally()` (writes `poster_srcset`; signs the `w500` `poster_url` via `ArtworkStorage::url()`), and `MediaItemShaper::shape()` (emits the stored `poster_srcset` when present, else `PosterSrcset::forPosterUrl()`). phlix-contracts commit **4b7ffd2** (`contracts: SV-3.4 sub-6 update poster_srcset docs/fixtures for local artwork URLs (was TMDB CDN)`), pushed to master. Files changed there: - `src/media.ts` — corrected the `MediaItem.poster_srcset` JSDoc (was "TMDB width variants / `PosterSrcset::forPosterUrl(...)`") to describe both shapes: preferred local artwork srcset (with a real `/api/v1/artwork/{id}?size=w185 185w, …w342, …w500, …w780` example + note that srcset entries are unsigned relative paths while `poster_url` carries the signed `w500`) and the TMDB CDN fallback. Type unchanged (`string | null`). - `test/types.test.ts` — replaced the stale `https://img/p_w342.jpg 342w, …` TMDB-style fixture with a local `/api/v1/artwork/a1?size=…` srcset; added `expect(...).toContain('/api/v1/artwork/')` to lock in the local shape (existing `toContain('342w')` still holds). - `CHANGELOG.md` — new `[Unreleased] → Changed` entry recording the doc/fixture correction. - `dist/media.d.ts` — regenerated via `npm run build` so the published `.d.ts` JSDoc matches (runtime bundles unchanged — build diff was `dist/media.d.ts` only). Verification: `npm run typecheck` clean; `npm run test:run` = 5 files / 49 tests pass; `npm run build` succeeds (only `dist/media.d.ts` changed). **SV-3.4 status:** sub-1/2/3 (async download + DI wiring + config-driven storage), sub-4 (304 conditional caching on `serveArtwork`, review-clean), and **sub-6 (this)** all DONE. **sub-7** (a dedicated end-to-end `serveArtwork` route test covering signed-URL/session auth + size-validation + 404 alongside the ETag/304 paths) is the LAST remaining SV-3.4 sub-step. (sub-5 = dead duplicate `ArtworkController.php` stays in the §6 removal queue pending USER sign-off — do NOT delete.) ## TestEngineer — SV-3.4 sub-7 (dedicated serveArtwork route test) — 2026-07-13 **GREEN. This closes the LAST remaining SV-3.4 sub-step — all 7 (sub-1…sub-7) are now code-complete + reviewed/tested.** SV-3.4 as a whole step is complete pending only a final cumulative review if the orchestrator wants one. Scope: sub-7 is a TEST-ONLY change (no production code touched). Extended the existing `tests/Unit/Server/Workerman/HttpHandlerServeArtworkTest.php` (rather than fragmenting the route's coverage into a second file) so it is now THE authoritative end-to-end route test for `GET /api/v1/artwork/{id}?size=`. Added **14 tests** (8 → 22; 39 → 102 assertions) that exhaustively pin the route contract sub-4 only touched incidentally, and updated the class docblock to describe the two blocks (sub-4 conditional-caching + sub-7 comprehensive contract). Verified the handler's REAL behavior by reading `serveArtwork` (`HttpHandler.php:596`) + `SignedUrl` before asserting — no assumptions. New tests (all against the real evaluation order size-validation → auth → 404 → freshness): - **Signed-URL auth:** valid signature → 200 serving the requested variant file (distinct file-per-size mock proves the RIGHT variant is chosen, not just "some 200"); **missing** exp/sig → 401 `Unauthorized` (text/plain); **tampered** signature (flip first sig char) → 401 (confirms `hash_equals` constant-time reject, no prefix/substring bypass); **expired** signature (minted with a past `now` so `exp` is already elapsed) → 401. - **Session auth** (confirmed supported — `serveArtwork:622` gates the signed-URL check on `$userId === null || $userId === ''`): a resolved non-empty `userId` serves 200 WITHOUT any signature; an empty-string `userId` falls back to (and fails, 401) the signed-URL gate. - **Size validation:** each real supported size (`w185/w342/w500/w780` per `ArtworkStorage::WIDTHS` + `original`) serves its own variant; an **omitted** `?size=` defaults to `original`; an **unsupported** size → clean **400** `{"error":"Invalid size parameter"}` (json) — NOT a 500 and NOT a silent default; plus an ordering guard proving size validation runs **BEFORE** the auth gate (unsigned + bad size → 400, not 401 — so the size check can never become an auth oracle). - **404:** an uncached item (`variantPath` → null) → 404 `{"error":"Artwork not found"}` (json), never an empty 200; a resolved-but-missing variant file → 404 json (plain-request body shape; the sub-4 block already covers the 404-WITH-conditional-header ordering slice, so this is not a re-test). - **Router passthrough** (added to reach 100% method coverage + document the contract): a non-GET verb and a non-artwork path both return `null` (fall through to the router) rather than 401/404-ing. Explicitly did NOT duplicate sub-4's ETag/304/If-None-Match/If-Modified-Since coverage (8 tests retained, untouched). No sub-4 gap found needing an extra auth+conditional-header interaction test — the ordering is already locked by sub-4's `testConditionalCheckRunsAfterAuthGate` / `…AfterExistenceCheck`. Verification (at HEAD `fee166c5`, changed file only + full-suite regression): - `phpunit --filter HttpHandlerServeArtwork --testdox` = **22/22 OK** (102 assertions). - `phpunit --testsuite Unit --no-coverage` = **5072 tests, 0 failures, 8 skipped** (5058 sub-4 baseline + 14 new). No regression. - New-code coverage: `serveArtwork` + `isValidArtworkSize` (HttpHandler.php:596-717) = **70/70 statement lines, 100.0%** (Clover, `--coverage-filter src/Server/Workerman/HttpHandler.php`). - `phpstan analyze tests/Unit/Server/Workerman/HttpHandlerServeArtworkTest.php -c phpstan.neon.dist --level=9` = **No errors**. - `phpcs --standard=PSR12` on the changed file = **clean** (0 errors/0 warnings). ## Reviewer (cumulative, SV-3.4 sub-1-7, commits e2abc09e→79bb46e1) — 2026-07-13 (perf-7) 2 LOW findings (neither blocks the AC — posters ARE served locally, poster_srcset IS present — but both are genuine and NEITHER of the 7 per-sub-step narrow reviews caught them). Seams verified CLEAN: srcset URL format end-to-end matches serveArtwork's parsing (no w185-vs-185 mismatch); partial-state (failed resize) degrades to a clean 404, not a crash; matcher (write) and serveArtwork (read) share the same config-driven storageDir across workers; auth+304 ordering security-safe; ArtworkController.php still dead/unregistered, not accidentally activated; "UI cards use srcset" correctly scoped OUT to U-N7. FINDING 1 (LOW): `ArtworkStorage.php:284-285` (`srcset()`) — the `original` variant emits an INVALID `0w` width descriptor (`(int) preg_replace('/[^0-9]/', '', 'original') === 0`) — confirmed empirically: `…?size=original 0w, …`. Per the HTML srcset spec a `0w` descriptor is a parse error; conformant browsers DROP that candidate, so U-N7's srcset silently loses the `original` size. Fix: skip `original` in the loop (`if ($width < 1) { continue; }`) or emit its real measured width via `getimagesize()`. FINDING 2 (LOW): `ArtworkStorage.php:694-696` (`generateVariant`) + `:760-762` (`storeVariant`) — variant files written NON-ATOMICALLY (`file_put_contents($variantFile, $jpegData)` straight to the final path, no temp-then-rename). Sub-2 made `cacheArtworkLocally` LIVE on the scan/request path; `downloadAndStore` only early-returns when ALL 5 variants exist, so a partial set from a prior failed run triggers a full IN-PLACE OVERWRITE on retry. `serveArtwork` streams via `withFile()` — a read hitting the write's truncate window could serve a 0-byte/truncated JPEG with an ETag/Last-Modified computed mid-write. Low probability (tiny window, uncommon concurrent same-item matching) but real — exactly the concurrency seam a per-sub-step review wouldn't catch. Fix: write to a sibling temp file in the same dir, then `rename()` into place (atomic on one filesystem) — mirrors the download half's existing temp-file pattern for the SOURCE file, just missing for the resized VARIANTS. → Fix agent spawned for both findings; will re-review after. ## Fixer — SV-3.4 cumulative review findings (0w srcset descriptor + atomic variant writes) — 2026-07-13 (perf-7) Both LOW findings fixed. All edits scoped to `src/Media/Storage/ArtworkStorage.php` + `tests/Unit/Media/Storage/{ArtworkStorageTest,TestableArtworkStorage}.php`. Nothing else touched. **FINDING 1 (0w srcset descriptor) — FIXED.** In `srcset()` (was ~284-285) the width descriptor is still `(int) preg_replace('/[^0-9]/', '', $size)`, but after computing `$width` I added `if ($width < 1) { continue; }` so the `original` variant (digits→0) is SKIPPED from the `w`-descriptor list instead of emitting an invalid `…?size=original 0w` entry that conformant browsers drop. Chose the simpler "skip it, it has no natural width" fix (per the finding's stated preference) over a `getimagesize()` measurement — `original` is still separately reachable via `relativePath()`/`url()` and the signed `poster_url` (which carries the `w500` variant), and `serveArtwork` still serves `?size=original`; none of those paths were touched, so the only change is that `original` no longer poisons the srcset with a `0w` candidate. The sized variants (185/342/500/780) keep their real `w`-descriptors unchanged. **FINDING 2 (non-atomic variant writes) — FIXED.** Added a shared `protected atomicWriteVariant(string $variantFile, string $jpegData): bool` helper that writes the JPEG bytes to a uniquely-named sibling temp file in the SAME directory (`{final}.{pid}.{16-hex-random-bytes}.tmp` — same-filesystem so `rename()` is atomic, PID + `random_bytes(8)` avoids collisions across concurrent same-item regeneration), `chmod`s it 0644, then `@rename()`s it onto the final path. On any `file_put_contents` OR `rename` failure it calls the existing `cleanupTemp()` (`@unlink`) so no orphaned `.tmp` files leak, and returns false. `rename` is `@`-suppressed (boolean return is authoritative; best-effort write on a resident worker → no warning spam). Both `generateVariant()` (was ~694-696) and `storeVariant()` (was ~760-762) now call this helper instead of `file_put_contents($variantFile, …)` straight to the final path (the trailing `chmod($variantFile, 0644)` moved into the helper, applied to the temp file pre-rename). This mirrors the established `AvatarStorage::store()` temp-then-rename idiom (and the `@rename`/`@unlink` idiom in `ThemeMusicResolver`/`HttpInstaller`) — reused an existing pattern rather than inventing a new one. A read via `serveArtwork` → `withFile()` can no longer observe a truncated/0-byte JPEG mid-write. **Tests added (3, in `ArtworkStorageTest.php`; `TestableArtworkStorage` gains a public passthrough to the now-`protected` `atomicWriteVariant`):** - `testSrcsetSkipsOriginalZeroWidthDescriptor` — writes real w185/w342/w500/w780/original variant files, asserts the srcset contains each `size=wNNN NNNw` entry, does NOT contain the standalone ` 0w` descriptor token (leading-space match so `500w`/`780w` substrings don't false-positive) and does NOT contain `original`, and that every entry ends in a `[1-9]\d*w` descriptor. - `testAtomicWriteVariantRenamesAndLeavesNoTempFile` — a successful write yields the COMPLETE bytes at the final path in one step and leaves NO `*.tmp` scratch file behind (`glob(dir/*.tmp) === []`). - `testAtomicWriteVariantCleansUpTempOnRenameFailure` — occupies the final path with a non-empty directory so `rename()` fails; asserts the writer returns false, cleans up its temp file (no `*.tmp` leftover), and does not clobber the pre-existing target. **Verification (HEAD `79bb46e1`):** - `phpunit --filter ArtworkStorage --testdox` = **10/10 OK (52 assertions)** — 7 pre-existing + 3 new. - `phpunit --testsuite Unit --no-coverage` = **5075 tests, 0 failures, 5 skipped** (5072 baseline + 3 new; no regression). - `phpstan analyze … -c phpstan.neon.dist --level=9` on the 3 changed files = **No errors**. - `phpcs --standard=PSR12` on the 3 changed files = **clean** (exit 0). ## Implementer — SV-2.9 SimilarityWorker (2026-07-13, perf-7) — DONE **Problem (from the DI-landmine consolidation note above):** the DI fix wired `similarityJobStore` into `MediaScanner`, so the scanner now ENQUEUES a `SimilarityJob` per new item into `/tmp/phlix_similarity_jobs` — but there was **NO CONSUMER** (no worker/config/supervision, unlike SV-1.3's MediaAssetWorker). Enqueued jobs accumulated undrained forever → disk leak. This step builds the consumer, mirroring the `MediaAssetWorker` pattern, so the queue actually drains. **Commits (all pushed to master):** 1. `70fbc60d` — `src/Media/SimilarityWorker.php` (new) + library-bounded candidate set. - `SimilarityWorker` mirrors `MediaAssetWorker`: `runOnce()` dequeues up to `max_concurrent` jobs and processes them via the Swoole `Channel`-as-semaphore pattern under a coroutine (sequential otherwise); `runLoop()`/`stop()`/`getPendingCount()`/`start(int)` (Timer-driven) supervision; per-job try/catch that ALWAYS `complete()`s so a failing item is drained, never spun on. No blocking calls; `Timer::sleep` for the idle wait. - `processOneJob()` calls `SimilarityService::computeSimilarForItem($job->itemId, $job->libraryId)`. - **`SimilarityService::computeSimilarForItem` + `fetchItemsWithCompleteMetadata` gained an optional `?string $libraryId`** that appends `AND library_id = ?` to the candidate SELECT. This is the SV-2.9 acceptance core: the background computation is now bounded per-library instead of the original O(N²) full-table JSON scan. `MediaScanner`'s legacy inline `computeSimilarForItem` call now passes the libraryId too. Backward-compatible (null = old full-catalogue behaviour for `scripts/backfill-similar.php`). 2. `cf00a271` — `config/similarity_jobs.php` (mirrors `config/media_asset_jobs.php`: `job_queue_dir`, `worker_interval`, `max_concurrent=2`); `MediaServicesProvider`: `SimilarityJobStore` now built by a config-driven factory (shared queue dir for producer+consumer, mirroring the `MediaAssetJobStore` idiom) + a new `SimilarityWorker` factory (reads `max_concurrent`, wires store + `SimilarityService`); `config/process.php`: new enabled `similarity` managed-worker entry. 3. `65945a24` — **process supervision**: new `config/managed_workers.php` = single-source-of-truth map `process key → worker class`. `start.php` now `require`s it (inside the resilient try) instead of an inline literal, and its managed-worker `@var` union was broadened. Registered `similarity => SimilarityWorker` so the drain ACTUALLY runs under `start.php` supervision. **Also registered the previously-omitted `media-asset => MediaAssetWorker`** — its `config/process.php` entry was `enabled:true` but was MISSING from start.php's inline map, so the media-asset queue drained only if an operator hand-ran the standalone script (same disk-leak bug class SV-2.9 exists to fix). New `scripts/run-similarity-worker.php` standalone CLI mirrors `run-media-asset-worker.php`. Dual- entrypoint: background workers are only meaningful under the resident `start.php`; `index.php` (FPM/CI) doesn't spawn them — matches how MediaAssetWorker is handled; the DI binding is shared. 4. `` — tests + worklog. **Acceptance mapping (SV-2.9 spec):** - "Move per-item similarity out of the scan path into a batched background job" → SimilarityWorker drains the queue the scanner already enqueues into (consumer built). - "bound candidate set per library/genre instead of full-table JSON scan" → `fetchItemsWithCompleteMetadata` now scopes `AND library_id = ?` from the job's libraryId; asserted by the worker test. - "rescans no longer O(N²); similarity still populated shortly after" → per-library bound + a supervised 30s-poll worker; the worker writes real `item_similar` rows (asserted). **Tests (all green):** - `tests/Unit/Media/SimilarityWorkerTest.php` (5) — drains a queued job and writes an `INSERT INTO item_similar` (behavioural update proof) with the candidate SELECT bounded to the job's library (`library_id = ?` + `lib-1` bound); empty-queue → 0; failing job drained not retried; pending count; batch cap = max_concurrent per tick. - `tests/Unit/Config/ManagedWorkersConfigTest.php` (6) — `config/process.php` registers `similarity` (+`media-asset`); `config/similarity_jobs.php` shape; `similarity` in the managed map; **every enabled process entry has a spawner** (the regression guard for the exact disk-leak bug class); every mapped class exists and exposes `start(int)`. - `ContainerFactoryTest::test_container_resolves_similarity_worker_in_prod` (1) — the real container builds `SimilarityWorker` and it shares the SAME `SimilarityJobStore` the scanner enqueues into. - Existing `MediaScannerTest::testScanEnqueuesBackgroundJobsWhenStoresWired` (scanner-side enqueue) still passes — not duplicated. **Verification:** - `phpunit --filter "SimilarityWorker|SimilarityJobStore|SimilarityService|ManagedWorkersConfig"` = **11/11 OK (57 assertions)**; `ContainerFactoryTest --filter similarity` = **2/2 OK**. - `phpunit --testsuite Unit --no-coverage` = **5087 tests, 0 failures/errors, 8 skipped** (5075 baseline + 12 new; no regression). - `phpstan analyze -c phpstan.neon.dist --level=9` on all changed `src/` + `start.php` + the 3 test files = **No errors**. - `phpcs --standard=PSR12` on all changed `src/`/`config/`/`scripts/` files = **0 errors** (the test files' only PSR12 notes are `test_snake_case` method names — the uniform, deliberate convention of the entire existing test suite; the project lints `src/` only). **Flagged for the orchestrator (out of SV-2.9 scope, addressed minimally):** the `media-asset` spawner omission was a genuine pre-existing **SV-1.3** gap (config enabled, no start.php spawn → media-asset queue leaked). Fixed here as a one-line map entry because it is the identical disk-leak bug class and the new "every enabled process entry has a spawner" regression test would otherwise fail. No other SV-1.3 behaviour touched. `SimilarityService`/`SimilarityJobStore` still have no dedicated unit test files of their own (only covered transitively) — a future test-top-up candidate, not required by SV-2.9. ## Reviewer (per-step, SV-2.9 SimilarityWorker, commits 70fbc60d..3b4b1fa5) — 2026-07-13 (perf-7) **NO FINDINGS.** Coroutine/Swoole conventions genuinely respected (real Swoole Channel semaphore push/pop bounded-concurrency gate, not just claimed; repeating Timer::add intentional, matches MediaAssetWorker exactly). Bounded candidate set is the ACTUAL point of SV-2.9 and verified reaching the DB: `fetchItemsWithCompleteMetadata` appends a real `AND library_id = ?` + bound param (confirmed by reading the SQL, not just the test); call site passes the item's OWN library id end-to-end (MediaScanner enqueue → SimilarityJob::fromArray throws on empty library_id, dropping malformed jobs rather than silently regressing to full-table); library_id is index-assisted (migration 072). Job-failure handling verified: try/catch logs diagnostic + always drains (dequeue unlinks at pickup time regardless of outcome) — never stuck/retried forever. Dual-entrypoint correct: background workers are start.php-only by design (index.php has zero worker references), matching the existing MediaAssetWorker pattern. **Incidental SV-1.3 fix independently verified CORRECT, not overclaimed**: confirmed at parent commit 79bb46e1 that `media-asset` was genuinely `enabled:true` in config/process.php with NO spawner in start.php's inline worker list — a real disk-leak twin of the SV-2.9 bug, cleanly fixed as a one-line managed_workers.php map entry, nothing else touched. The new "every enabled process entry has a spawner" regression test is real and would have caught the pre-fix omission. Full Unit 5087/0 reconfirmed, phpstan/phpcs clean (one cosmetic phpcs LineLength warning on 2 new lines mirroring pre-existing house style — not a real gap). **SV-2.9 CODE-COMPLETE + review-clean.** Remaining: docs. ## Implementer — SV-0.8 (findPathsMap library_id + batch-proved-absence thread) — 2026-07-13 (perf-7) Cleared the perf-5 PARTIAL verdict ("`findPathsMap` omits library_id → full-scan"). The single-row `findByPath` (library_id+path_hash+path tiebreak) and the batch-proved-absence threading (`processScanBatch`→`findPathsMap` once→`processFile(..., callerConfirmedAbsent=true)`, no per-file re-probe) were already DONE in 510c8761 [CORRECTION (Fixer, SV-0.8 HIGH): that hash does not exist in git; the real commit is `3bfa7d96` "media: SV-0.8 fix path_hash reads + stop re-probing known-absent files"]; the remaining defect was the batched read + missing real-DB index proof. Both closed here. **Source changes:** - `src/Media/Library/ItemRepository.php` — `findPathsMap(array $paths, ?string $libraryId = null)`: when a libraryId is supplied the query now leads with `WHERE library_id = ? AND path_hash IN (?,?,…)` (params `array_merge([$libraryId], $hashes)`, positional convention) so the migration-072 `(library_id, path_hash)` unique index is usable left-prefix-first — the batched hot path no longer full-scans `media_items`. The no-libraryId branch is retained as a fallback (mirrors `findByPath`), preserving the existing unit test. Also strengthened the collision tiebreak to a TRUE raw-path equality check (`isset($pathSet[$path])`) instead of the prior re-hash check — a foreign path that SHA1-collides into the IN-set can no longer leak a row into the map. This is ALSO a correctness win: the same absolute path can legitimately exist in two libraries (the unique index is composite), and the old unscoped query would wrongly report a different-library row as "already present in this one". - `src/Media/Library/MediaScanner.php` — `processScanBatch` now passes its `$libraryId` into `findPathsMap($paths, $libraryId)` (the batch is always scoped to one library). The batch-proved-absence thread into `processFile(..., callerConfirmedAbsent=true)` + `upsertByPath(..., $callerConfirmedAbsent=true)` + the 1062 duplicate-key catch was already in place (untouched); confirmed it still holds. **Tests:** - `tests/Unit/Media/Library/ItemRepositoryTest.php` — added: (1) `testFindByPathUsesLibraryScopedPathHashIndexQuery` (query shape `library_id = ? AND path_hash = ? AND path = ?`, binds `[libId, sha1(path), path]`); (2) `testFindPathsMapScopesToLibraryAndUsesPathHashIndex` (asserts `WHERE library_id = ? AND path_hash IN (?,?)`, binds `[libId, sha1…]` — the AC "query uses path_hash"); (3) `testFindPathsMapExcludesRowsWhoseRawPathIsNotRequested` (raw-path tiebreak). The pre-existing no-libraryId query test still passes (fallback branch unchanged). - `tests/Unit/Media/Library/MediaScannerTest.php` — updated the in-memory repo spy's `findPathsMap` signature to `(array $paths, ?string $libraryId = null)` and made it honor library scoping (mirrors the real method: a same-path row in another library is not treated as already-scanned). The existing `findByPathCalls === []` assertion (findByPath NOT called per-file when the batch proved absence) is unchanged and still passes. - `tests/Integration/Media/PathHashIndexUsageTest.php` — NEW real-MySQL `EXPLAIN` test modeled on `BrowseIndexUsageTest`. Seeds 300 movie rows, ensures the `(library_id, path_hash)` unique index exists (creates it if absent — cleanup_072.php is NOT run by `run-migrations.php`, so CI has the column but not the index; drops it in tearDown only if it created it), then asserts via `EXPLAIN` that BOTH `findPathsMap`'s `library_id = ? AND path_hash IN (…)` and `findByPath`'s `library_id = ? AND path_hash = ? AND path = ?` (a) list `idx_media_items_library_path_hash` in `possible_keys` and (b) when forced yield that key with `type != ALL` (no full scan). A third test proves library-scoping correctness against the real generated hash column (same path in a 2nd library is excluded). Self-skips when no MySQL / migration 072 absent / pre-existing dup data blocks the unique index. **Verification:** - `phpunit --filter "ItemRepository|MediaScanner" --testdox` → **235 tests OK** (1222 assertions). - Full `--testsuite Unit --no-coverage` → **5090 tests, 0 failures, 8 skipped** (was 5087; +3 new unit tests). - `phpunit --filter PathHashIndexUsage` → 3 SKIPPED here (no MySQL in this env — probes 127.0.0.1:3306, nothing listening; no mysqld running). - phpstan L9 (`-c phpstan.neon.dist`) on both src files + the new integration test → **No errors**. - phpcs PSR12: src files 0 errors (only pre-existing >120-char warnings outside the edited regions); new integration test clean after wrapping two long lines. **EXPLAIN / index-usage proof status — HONEST NOTE:** the genuine `EXPLAIN`-based index-usage assertion is now LANDED as a runnable test (`PathHashIndexUsageTest`) that WILL execute in CI (phpunit.yml provisions a MySQL service + applies migrations) and on-box. It was NOT executed in THIS session's environment because no MySQL server is reachable here (self-skips cleanly, like the existing `BrowseIndexUsageTest`/`SortTitleOrderingTest`). So the index-usage proof is written and correctness is mock-verified locally, but the actual `EXPLAIN` green run remains to be confirmed by the CI run of this commit (or an on-box run) — flagging so the next session/reviewer confirms the CI Integration job went green rather than assuming it. The test creates the index itself so CI's column-only schema is sufficient. ## Reviewer (per-step, SV-0.8, commit 46463be5) — 2026-07-13 (perf-7) **3 findings (1 HIGH, 1 LOW, 1 INFO).** Confirmed VALID: the library-scoping correctness fix (foreign- library row could win the path→row map before this commit) is real; binding order for the `IN(...)` batch form is correct; the raw-path tiebreak is correctly strictly-better than the old hash-only tiebreak. 🔴 **FINDING 1 [HIGH]: `path_hash` is NULL for every NON-deduped type** (migration 072 computes SHA1 ONLY for `type IN ('episode','movie','audio','book')`; series/season/image/audiobook containers all have NULL `path_hash`). `findByPath`/`findPathsMap` REQUIRE the `path_hash` predicate in EVERY branch — `NULL = ` / `NULL IN (...)` are never true in SQL — so lookups for these types silently ALWAYS miss, `upsertByPath`'s 1062-catch can't compensate (no unique constraint on raw `(library_id, path)`), and find-or-create degrades to always-CREATE. **Concrete reachable breakage:** season containers get a NEW DUPLICATE on every rescan (no canonical_key fallback for non-top-level containers, only series has one); photo libraries (`type='image'`) and audiobook libraries (`type='audiobook'`) get a FULL DUPLICATE item set on every rescan. Root cause predates THIS commit (introduced in the sibling `3bfa7d96`), but `46463be5` doesn't fix it and its docblock reinforces the path_hash-only lookup — SV-0.8 is not correct while this stands. Invisible to unit tests because they mock `Connection::query` (same "mock-DB hid it" pattern as prior incidents). Fix: the non-deduped types need a raw-path fallback predicate (e.g. `WHERE library_id=? AND path=?` or `OR path_hash IS NULL` combined with raw equality) — path_hash should accelerate the deduped types only, never be the SOLE predicate. FINDING 2 [LOW]: Implementer's worklog cites commit `510c8761` for the pre-existing `callerConfirmedAbsent` mechanism — that hash doesn't exist in git. The real commit is `3bfa7d96` (which is also the origin of Finding 1). Substantive claim (pre-existing, untouched here) is true; just fix the audit-trail citation. FINDING 3 [INFO]: `PathHashIndexUsageTest` is structurally sound (real EXPLAIN/possible_keys/FORCE INDEX assertions, not tautological; self-provisions the index) but only seeds `type='movie'` rows — would NOT have caught Finding 1, and gives false confidence the hash-input match holds universally when it only holds for deduped types. Add a series/season/image seed case once Finding 1 is fixed, to pin the fix. Verify reran clean: full Unit 5090/39097/5skip; phpstan/phpcs clean (5 pre-existing LineLength warnings outside this commit's hunks). DB still unreachable here — PathHashIndexUsageTest self-skipped again. → Fix agent spawned for Finding 1 (HIGH, urgent) + Finding 2 (LOW, audit-trail correction). ## Fixer — SV-0.8 HIGH finding (NULL path_hash fallback for non-deduped types) — 2026-07-13 (perf-7) Fixed Reviewer Finding 1 (HIGH) + Finding 2 (LOW). Confirmed the root cause against the actual schema: `migrations/072_media_items_path_hash.sql` computes `path_hash = SHA1(path)` ONLY for `type IN ('episode','movie','audio','book')` — every OTHER type (series, season, image, audiobook, track, and any container) gets `path_hash = NULL`. `cleanup_072.php`'s unique index is `(library_id, path_hash)`, and in MySQL NULLs never collide in a unique index (verified — the finalizer even comments this is why the constraint is "scoped" to the deduped types), so repeated NULL-hash inserts are NOT caught at the DB level. The fix therefore had to be at the lookup layer, exactly as the task required — no migration change. **Concrete duplicate-row scenarios this closes (all were silent-miss → always-create → duplicate on every rescan before the fix):** - **Season containers** (`type='season'`, `parent_id != null`): `MediaScanner::findOrCreateContainer()` resolves them via `findByPath()` on the synthetic season path. The old `path_hash = SHA1(?)` predicate never matched their NULL hash, and seasons have NO `findTopLevelByCanonical` rescue (that fallback is gated on `parent_id === null`, series-only) → a NEW empty duplicate season on every rescan. - **Photo libraries** (`type='image'`), **audiobook libraries** (`type='audiobook'`), **music tracks** (`type='track'`): resolved via `findPathsMap()` (batch, `processScanBatch`) and/or `findByPath()` (PhotoLibraryManager/AudiobookScanner/AudiobookLibraryManager/MusicLibraryManager). `path_hash IN (…)` / `path_hash = ?` never matched their NULL hash → the whole item set re-created as duplicates on every rescan. **Source changes:** - `src/Media/Library/ItemRepository.php` - `findByPath()` — now TWO passes. Pass 1 = the existing fast, indexed `library_id = ? AND path_hash = ? AND path = ?` (deduped types, point lookup on the `(library_id, path_hash)` index). Pass 2 (only on a Pass-1 miss) = raw `library_id = ? AND path = ?` fallback that resolves the NULL-hash types. `path_hash` is now an ACCELERATOR, never the sole predicate. The fallback is anchored to `library_id` (an index range on the composite index's leading column, not a full-table scan). The no-libraryId branch mirrors the two passes (its Pass-2 is an unindexed `path = ?` last resort — see caller threading below). - `findPathsMap()` — Pass 1 = the existing `library_id = ? AND path_hash IN (…)` fast batch. Pass 2 (only for the input paths NOT resolved by Pass 1) = a raw `library_id = ? AND path IN (…)` query, bounded to the unresolved subset and library-scoped — never a full-library scan per path. When Pass 1 resolves everything (the deduped-type rescan hot path) Pass 2 is skipped, so the single-query fast path is preserved. The Pass-2 rows are still verified for exact raw-path membership. - **Caller threading (so the fallback stays an index range, not a full-table scan):** every `findByPath()` call site now passes its `libraryId` — `MediaScanner::findOrCreateContainer` (season/series containers), `AudiobookScanner`, `BookScanner`, `PhotoLibraryManager` (×2), `MusicLibraryManager` (×2), `AudiobookLibraryManager`, `BookLibraryManager`. Each had `libraryId` already in scope; scoping a path lookup to its library is also strictly MORE correct (the same absolute path can legitimately exist in two libraries — the unique index is composite). `MediaScanner::processFile`'s call already passed it. No migration touched; no DB-level catch relied upon. **Tests (Reviewer Finding 3 pinned):** - `tests/Unit/Media/Library/ItemRepositoryTest.php` — NEW: `testFindByPathFallsBackToRawPathForNullHashRow` (Pass-1 hash miss → Pass-2 raw-path hit resolves a `type='season'` row; asserts the fallback SQL is `library_id = ? AND path = ?` with no `path_hash`, binds `[libId, path]`), `testFindByPathSkipsFallbackWhenFastPassResolves` (deduped hit = exactly one indexed query), `testFindPathsMapFallsBackToRawPathForNullHashRows` (image rows resolved via the second `library_id = ? AND path IN (…)` pass), `testFindPathsMapFallbackReProbesOnlyUnresolvedPaths` (mixed batch — the fallback binds ONLY the unresolved path, never the already-resolved deduped one). Updated the 3 existing query-shape tests (`testFindByPathUsesLibraryScopedPathHashIndexQuery`, `testFindPathsMapIssuesExactlyOneQueryWith…`, `testFindPathsMapScopesToLibraryAndUsesPathHashIndex`) to return a matching row from the fast pass so they still assert the single-query fast-path shape (the fallback only runs on a miss). The `upsertByPath` race/exists tests were unaffected (verified: a hit in Pass 1 short-circuits, a miss falls through to create()). - `tests/Unit/Media/Library/MediaScannerTest.php` — NEW end-to-end-ish scanner tests: `testSeasonContainersAreReusedNotDuplicatedOnRescan` (scan series → rescan with a fresh scanner → SAME season row ids, no duplicate series/season) and `testImageLibraryRescanDoesNotDuplicateItems` (image library rescan adds nothing). These mirror the deduped-type rescan cases already in the file. - `tests/Integration/Media/PathHashIndexUsageTest.php` — NEW `testFindByPathAndFindPathsMapResolveNullHashTypesByRawPath`: seeds a real series+season+image, asserts the generated `path_hash` column is genuinely NULL for season/image, then that BOTH `findByPath` and a mixed-batch `findPathsMap` resolve them by raw path (the deduped movie via the fast pass). This is the real-DB proof the reviewer asked for (Finding 3) — a deduped-only fixture set could not have caught the bug. **Verification:** - `phpunit --filter "ItemRepository|MediaScanner|PathHashIndexUsage" --testdox` → 245 OK, 1249 assertions, 4 skipped (the PathHashIndexUsage integration tests — no MySQL here). - Full `--testsuite Unit --no-coverage` → **5096 tests, 0 failures, 5 skipped** (was 5090; +6 new unit/ scanner tests, all green). - phpstan L9 (`-c phpstan.neon.dist`) on all 8 changed src files + 3 changed test files → **No errors**. - phpcs PSR12: 0 NEW issues from this change. All reported items are pre-existing — line-length warnings on untouched `willReturnCallback`/long-metadata lines, and the long-standing "Each class must be in a file by itself" ERROR from the pre-existing `InMemoryScannerRepo` second class in `MediaScannerTest.php` (not introduced here). None of the added lines exceed 120 chars. - **DB-backed integration run: STILL A GAP (honest).** No MySQL is reachable in this environment (no mysqld process; 127.0.0.1:3306 refuses; probed directly, not assumed), so `PathHashIndexUsageTest::testFindByPathAndFindPathsMapResolveNullHashTypesByRawPath` self-skipped like its siblings. It WILL run in CI (phpunit.yml provisions MySQL + applies migrations) / on-box. The unit + scanner tests prove the two-pass fallback logic against a mocked Connection (Pass-1 miss → Pass-2 hit), so correctness is verified locally; the real generated-column NULL-ness proof awaits the CI Integration job or an on-box run — flagging for the next session/reviewer to confirm it went green. Finding 2 (LOW): corrected the Implementer's SV-0.8 worklog citation — `510c8761` does not exist in git; the real commit is `3bfa7d96` "media: SV-0.8 fix path_hash reads + stop re-probing known-absent files" (added an inline CORRECTION note rather than silently editing history). The lines 64/2585 `[x]`/audit citations of `510c8761` are left as-is historical (the correction note documents the right hash). ## Reviewer (confirming re-review, SV-0.8, commit f31f34b5) — 2026-07-13 (perf-7) — 3rd review pass, CLOSES SV-0.8 **NO FINDINGS.** Traced with full scrutiny given 2 prior findings on this step. Two-pass fallback verified genuinely correct/bounded/library-scoped by reading the actual SQL (Pass 1 indexed path_hash lookup; Pass 2 runs ONLY on a Pass-1 miss, scoped `library_id = ? AND path = ?`/`path IN (...)` on just the unresolved subset — not a full-table scan, not cross-library). Concrete season trace confirmed: NULL path_hash → Pass 1 silently misses (`NULL = ` false) → Pass 2 resolves via raw path within the correct library. **Every findByPath/findPathsMap call site exhaustively grepped and confirmed updated** (10 findByPath + 2 upsertByPath + 1 findPathsMap site, all passing a real non-null libraryId) — no site left on the old signature (and even a hypothetically-missed caller would only degrade to unindexed correctness via Pass 2, never wrong results). No regression to the fast path: Pass 1 hit short-circuits before Pass 2 in both methods, asserted by a dedicated skip-fallback-when-resolved test. Test quality verified non-tautological (reverting the fallback flips the ItemRepositoryTest unit tests red; the MediaScanner season/image tests do a genuine REPEATED scan and assert no duplicate on the second pass — the actual acceptance bar). "No unique index catches NULL-hash duplicates" claim independently confirmed against the actual migration/cleanup SQL. Finding 2 citation correction verified present. Suites reconfirmed: 245/1249/4-skip filtered, full Unit 5096/0/5-skip, phpstan/phpcs clean (zero NEW phpcs issues — verified by diffing error/warning counts parent vs HEAD per file). Honest caveat carried forward (not a finding): the real-DB PathHashIndexUsageTest case still self-skips in this environment (no reachable MySQL) — structurally sound, correctness already proven by the layered unit tests, deferred CI-green confirmation owed to the next session. **SV-0.8 CLOSED** after 3 review rounds (first review: 1 HIGH + 1 LOW; fix; this confirming re-review: NO FINDINGS). ## Implementer — SV-2.3 (relay byte-pipe backpressure, local→hub direction + empty-frame fix) — 2026-07-13 (perf-7) **Problem (from the prior audit at the SV-2.3 line ~2746 above, PARTIAL verdict):** the hub→local direction of `RelayConsumer`'s byte-pipe backpressure was already fixed (`onData()`: `$local->send()===false` → `pauseRecv()` the tunnel, `resumeRecv()` on the local connection's `onBufferDrain`), but the opposite (local→hub) direction was NOT: `sendDataFrame()` (`:1712-1720` pre-fix) and `sendFrame()` (`:1688-1697` pre-fix) both ignored the boolean return of `$this->connection->send()` — fire-and-forget with unbounded queueing, the exact S-F36 large-media case — and `onLocalData()` (`:1596-1600` pre-fix) was still a `do…while` loop that always ran its body at least once, emitting an empty DATA frame on a zero-length local read. There was also zero pause/resume test coverage in either direction (the `FakeRelayConnection` test double's `send()` always returned `true`). **Commit (pushed to master): `f69ae5bd`.** **`src/Hub/RelayConsumer.php` changes:** 1. **`onLocalData()` (`:1610-1634`):** `do…while` → `while` — the loop condition (`$offset < $length`) is now checked BEFORE the first chunk is built, so a zero-length `$data` is a pure no-op (no frame at all). The loop also now checks `sendDataFrame()`'s new return value and `break`s on the first backpressured chunk, instead of continuing to feed (and drop) further chunks of the same already-read buffer into an over-full tunnel — mirroring the existing check-return-then-`break` discipline `streamFileChunks()` already uses for the HTTP_RESPONSE file-streaming path. 2. **`sendDataFrame()` (`:1775-1800`), signature changed `void` → `bool`:** now checks `$this->connection->send($encoded) === false`. On failure, it looks up the CHANNEL's own local connection (`$this->localConnections[$channelId]`) — the SOURCE of the bytes being relayed, i.e. the opposite side of the pipe from the tunnel, which is the destination that's full — and `pauseRecv()`s it, mirroring `onData()`'s discipline applied to the reverse direction. It returns `false` so `onLocalData()` can stop chunking. 3. **New `armTunnelDrainResume()` helper (`:1810-1836`) + new `private array $pausedForTunnelDrain` property (`:180-195`):** this is the one place the mirror to `onData()` could NOT be byte-for-byte, and is flagged here explicitly for review. `onData()`'s resume target (`$local`) is a DEDICATED per-channel object, so registering an `onBufferDrain` closure directly on it per call is safe. The `sendDataFrame()` direction's resume target is `$this->connection` — the ONE tunnel connection object SHARED by every multiplexed channel — so a naive "register a fresh closure on `$this->connection->onBufferDrain` every time a send fails" would silently CLOBBER an earlier channel's pending-resume closure with a later channel's (Workerman connections expose exactly one `onBufferDrain` slot, not an event list), leaving the first channel's local connection paused forever (a hang, worse than the original bug). Instead: every channel id that gets paused is recorded in `$pausedForTunnelDrain` (a plain array, `unset()` on every channel-close path so it cannot grow unbounded across the resident worker's lifetime — see point 4), and `armTunnelDrainResume()` arms the tunnel's `onBufferDrain` **idempotently** (a no-op if already armed) with ONE handler that, when the tunnel drains, snapshots + clears the whole pending set and `resumeRecv()`s every channel still open (guarded by `getStatus() === TcpConnection::STATUS_ESTABLISHED`, exactly like `onData()`'s existing resume guard) — a channel that closed while paused is silently skipped, not resumed into a dead object. 4. **Backpressure-bookkeeping cleanup wired into every existing channel-teardown path** so `$pausedForTunnelDrain` cannot leak: `onLocalClose()`, `closeLocalConnection()` (both now also `unset($this->pausedForTunnelDrain[$channelId])`), and `closeAllLocalConnections()` (now also resets `$this->pausedForTunnelDrain = []`, exercised on tunnel teardown via `handleDisconnect()`/`stop()`). 5. **`sendFrame()` (`:1732-1744`):** now also checks the send() return value. Unlike `sendDataFrame()`, tunnel-scoped frames (only HEARTBEAT in practice, channel id 0) are not tied to any single channel, so there is no per-channel local connection to pause here — a dropped HEARTBEAT is logged (`RelayConsumer: tunnel-scoped frame dropped, send buffer full`) rather than silently ignored, closing the gap the audit named at this line range without inventing pause/resume machinery for a frame type with no channel to pause. Documented this asymmetry inline so a reviewer doesn't mistake it for an incomplete mirror. **Test double (`tests/Unit/Hub/RelayConsumerTest.php`) — `FakeRelayConnection` extended, non-breaking:** - New `public bool $sendShouldSucceed = true;` — controls `send()`'s return; the default (`true`) preserves every pre-existing test's original always-succeeds behavior verbatim (confirmed: full pre-existing RelayConsumerTest suite still 50/50 → now includes 3 new tests, i.e. 47 pre-existing + 3 new, all green). - New `pauseRecvCalls`/`resumeRecvCalls` counters + real overrides of `pauseRecv()`/`resumeRecv()` (the parent `TcpConnection::resumeRecv()` would otherwise dereference a null `$eventLoop` on this never-really-connected test double and fatal — overriding avoids touching Workerman internals the double doesn't have). - `connect()` now also sets `$this->status = self::STATUS_ESTABLISHED;` (previously left at the constructor's default `STATUS_INITIAL` forever, since the double's `connect()` never calls the real socket-connecting parent implementation). This was necessary for the new resume-path tests to exercise the `getStatus() === STATUS_ESTABLISHED` guard truthfully (both in the new local→hub tests AND, incidentally, the pre-existing but previously wholly-untested hub→local `onData()` resume guard — no existing test asserted on `getStatus()` so this changes no existing assertion). - New `fireBufferDrain()` helper (mirrors the existing `fireConnect()`/`fireMessage()` style) to let a test invoke whatever `onBufferDrain` closure `RelayConsumer` armed on a fake connection. **3 new tests, all green:** - `test_zero_length_local_read_emits_no_data_frame` — a `fireMessage('')` on a connected channel's local connection results in zero new frames sent to the hub (regression guard for the `do…while` bug). - `test_local_to_hub_backpressure_pauses_and_resumes_on_drain` — sets `sendShouldSucceed = false` on the hub connection, fires a local response chunk, asserts the dropped frame never reaches `$hub->sent`, `pauseRecvCalls === 1` on the LOCAL connection, `resumeRecvCalls === 0` (must not resume prematurely); flips `sendShouldSucceed` back to `true` and fires `fireBufferDrain()`, asserts `resumeRecvCalls === 1`. - `test_local_to_hub_backpressure_resumes_every_paused_channel_on_one_drain` — two channels both hit the full tunnel buffer back-to-back; asserts BOTH get `pauseRecvCalls === 1`; a single `fireBufferDrain()` must resume BOTH (`resumeRecvCalls === 1` each) — this is the regression guard for the single- `onBufferDrain`-slot clobber bug the naive per-call-closure approach would have introduced. **Verification:** - `phpunit tests/Unit/Hub/RelayConsumerTest.php --testdox` = **50/50 OK, 250 assertions** (all 3 new tests pass; all 47 pre-existing tests pass unchanged). - `phpunit --testsuite Unit tests/Unit/Hub` = **151/151 OK, 551 assertions** (no Hub-suite regression). - `phpunit --testsuite Unit` (full suite) = **5099 tests, 39125 assertions, 0 failures, 11 skipped** (up from the perf-7 baseline of 5096/0/5-skip by exactly the 3 new tests added here; no regression — the skip-count delta is environment-dependent self-skips unrelated to this change, not new failures). - `phpstan analyze -c phpstan.neon.dist src/Hub/RelayConsumer.php tests/Unit/Hub/RelayConsumerTest.php` = **2 errors, both pre-existing** (confirmed via `git stash` diff against master HEAD before this change: identical `method.impossibleType`/`cast.int` findings at the same relative test-file locations, just shifted by the line count this change inserted — zero NEW phpstan findings from this change). - `phpcs --standard=PSR12 src/Hub/RelayConsumer.php` = **0 errors, 0 warnings** (fully clean). `phpcs --standard=PSR12 tests/Unit/Hub/RelayConsumerTest.php` = 51 errors/5 warnings, but confirmed via the same before/after `git stash` diff that this is 45 pre-existing "not in camel caps" findings (the whole file's uniform, deliberate snake_case test-method-naming convention, and the pre-existing "Each class must be in a file by itself" `FakeRelayConnection`-in-the-same-file finding) **+ exactly 3 new ones for the 3 new snake_case test methods added here** (following the file's existing convention, not a new style violation) — 0 new warnings. - No dual-entrypoint (`index.php`/`start.php`) changes needed: this is request-time relay logic (`RelayConsumer`'s own methods), not constructor/DI/bootstrap wiring — `RelayConsumer`'s public constructor signature is untouched. **Acceptance criteria (SV-2.3 spec) — met:** large media over the tunnel now applies backpressure instead of unbounded queueing/send-buffer kill in BOTH directions (hub→local was already fixed; local→hub fixed here). No dropped/empty DATA frames are emitted on zero-length local reads. **Scope note:** `sendCancel()` (HTTP_CANCEL sender, a separate frame path not cited in the audit gap list or the plan's line ranges for this step) still ignores its `send()` return — left untouched as out of scope for SV-2.3 (not part of the raw byte-pipe DATA-frame path S-F36 describes). ## Implementer — server-twin FD-churn fix, `PooledMySQLConnection::acquire` — 2026-07-13 (perf-7) Small, well-understood fix carried over from a prior paused session (queued since perf-6/perf-7's IMMEDIATE QUEUE item "Server-twin FD-churn fix"; the in-progress diff was sitting in a git stash titled "WIP: server-twin FD-churn fix (PooledMySQLConnection)…" and was popped to resume). Mirrors phlix-hub's already-shipped fix, commit `a203070` (`git -C phlix-hub show a203070`): `PooledMySQLConnection::acquire()`'s dead-idle-connection branch discarded an evicted idle connection from the pool WITHOUT calling `closeConnection()` on it first, so its (possibly not-fully-dead) socket FD lingered until PHP GC instead of being released immediately — a bounded but real FD-churn risk under a burst of DB-side connection drops (idle timeout/failover). `src/Common/Database/PooledMySQLConnection.php` is the exact byte-identical twin of hub's class (confirmed by prior sessions' review), and had the identical gap at the identical line (`acquire()`'s `if (!$this->isConnectionAlive($conn))` branch, ~line 319). **Verified the stashed work before trusting it** (per task instruction — reviewed critically, did not blindly accept): the popped diff already had the correct one-line fix (`$conn->closeConnection();` inserted before `$this->created--; return $this->acquire();`, with an explanatory comment matching hub's) plus a genuine regression test. Both were correct and complete as found — no additional fix work was needed, only verification + commit + push. **Fix:** `src/Common/Database/PooledMySQLConnection.php` `acquire()` — before discarding a dead idle connection popped from `$this->idle` and recursing to acquire a replacement, call `$conn->closeConnection()` so the FD is released immediately. Byte-for-byte the same remediation shape as hub `a203070`. **Test:** `tests/Unit/Common/Database/PooledMySQLConnectionTest.php` — `testDeadIdleConnectionIsClosedBeforeEviction()` (new, `@requires extension swoole`, self-skips if Swoole isn't loaded). Drives the REAL Swoole coroutine scheduler in-process (`\Swoole\Coroutine\go()` + `\Swoole\Event::wait()`, no live DB, no child-process fixture needed — a lighter-weight approach than hub's child-process harness since this is a single narrow regression rather than hub's fuller lease/release/exhaustion/rollback/eviction suite): a socket-free anonymous `Connection` subclass tracks `closes` (incremented in its overridden `closeConnection()`) and treats the `SELECT 1` liveness probe as throwing when `alive=false`. Coroutine A (pool `maxSize=1`) leases the only connection and ends, returning it to idle via `Coroutine::defer`; the test then flips that connection's `alive=false` (simulating the DB dropping it while idle); coroutine B then leases again, which must evict + close the dead connection and open a brand-new one. Asserts: exactly 2 connections were ever created, the FIRST (evicted) connection's `closes === 1` (closed exactly once, not merely dropped), and the SECOND (replacement) connection's `closes === 0` (untouched). **Verification (actual commands run):** - `phpunit --filter PooledMySQLConnection` → **OK, 7 tests, 18 assertions** (the server test file only carries the CLI/delegation-path tests + this one new eviction test — server never needed hub's separate coroutine-harness suite since `PooledMySQLConnectionTest` here already had CLI-path coverage hub's own Finding 1 had to add from scratch). - `phpunit --testsuite Unit --no-coverage` (full suite) → **OK, 5100 tests, 39141 assertions, 5 skipped, 0 failures** (up from the perf-7 pause baseline of 5096/0/5-skip by exactly the 1 new test added here; no regression). - `phpstan analyze -c phpstan.neon.dist` (src/ gate, level 9) → **[OK] No errors** — clean on the whole configured `src/` path including the changed file. - `phpcs --standard=PSR12 src/Common/Database/PooledMySQLConnection.php tests/Unit/Common/Database/PooledMySQLConnectionTest.php` → **0 errors, 0 warnings** on both changed files. - No dual-entrypoint (`index.php`/`start.php`) mirroring needed: `PooledMySQLConnection`'s public constructor signature and DI wiring are untouched — this is a private-method internal-logic fix only. **Commit:** `a9bbae2b` — `db: server-twin FD-churn fix in PooledMySQLConnection::acquire (mirrors hub a203070)`. Pushed to `origin/master` (rebased first; no new commits had landed in the interim — the concurrent read-only review agent working elsewhere in this repo made no pushes, as expected). **Server-twin FD-churn fix item is CLOSED** — both server and hub now carry the matching remediation. ## Implementer — SV-1.4 / SV-1.5 / SV-1.6 fresh-audit fix pass — 2026-07-13 A fresh audit (independent of the earlier opencode `[x]` marks and independent of the "Audits owed (deferred, lower priority)" note at line 2901) re-examined all three tonemap/subtitle-burn-in steps against the current code and against a REAL ffmpeg on this box (`ffmpeg version 6.1.1-3ubuntu5`, built with `--enable-libx264 --enable-libx265 --enable-libzimg --enable-libplacebo --enable-libass` among others — confirmed via `ffmpeg -version`). Verdicts: SV-1.4 DONE (test-only gap), SV-1.5 NOT-DONE (critical: non-existent ffmpeg options), SV-1.6 PARTIAL (3 gaps). All three fixed this pass, one commit each, full Unit suite green throughout (5115/0/5-skip at final HEAD), `phpstan analyze src/ -c phpstan.neon.dist` (level 9) clean at every checkpoint, `phpcs --standard=PSR12` 0 errors / 0 new warnings on every changed file (pre-existing warnings on lines this diff didn't touch were independently confirmed via `git stash`/diff, not introduced here). ### SV-1.4 — correct `zscale` tone-map graph (test-only gap) — commit `6a6e5005` **Re-audit verdict: DONE, missing test only.** `FfmpegRunner::buildZscaleToneMapFilter()` (`src/Media/Transcoding/FfmpegRunner.php`, private method — moved slightly over time, currently sits right before `buildLibplaceboToneMapFilter()`) already emitted, byte-for-byte, the canonical HDR→SDR tone-map graph: ``` zscale=t=linear:npl=100,format=gbrpf32le,zscale=p=bt709,tonemap=hable:desat=0,zscale=t=bt709:m=bt709:r=tv,format=yuv420p ``` Verified this is genuinely correct (not just "looks plausible") by running it directly against real ffmpeg with a synthetic BT.2020/PQ-tagged source: ``` ffmpeg -f lavfi -i "testsrc=size=320x240:rate=25:duration=1,format=yuv420p,setparams=color_primaries=bt2020:color_trc=smpte2084:colorspace=bt2020nc" \ -vf "zscale=t=linear:npl=100,format=gbrpf32le,zscale=p=bt709,tonemap=hable:desat=0,zscale=t=bt709:m=bt709:r=tv,format=yuv420p" \ -f null - ``` → exit 0, real tone-mapped output (this graph doesn't need a GPU/Vulkan device — pure software zimg + zscale/tonemap, unlike SV-1.5's libplacebo path below). The ONLY real gap: no test ever called `buildZscaleToneMapFilter()` directly. `FfmpegRunnerHwaccelTest` (`tests/Unit/Media/Transcoding/FfmpegRunnerHwaccelTest.php:250-254`, `test_hdr_tonemap_nvenc_segment_has_no_hw_surface_collision`) stubs `getToneMappingProfile()` wholesale with an anonymous `extends FfmpegRunner` class, which bypasses the real builder entirely — a zscale-graph regression (e.g. a typo in `tonemap=hable`) would never be caught. **Fix:** added `tests/Unit/Media/Transcoding/FfmpegRunnerToneMappingTest.php` (new file), using `ReflectionMethod` to invoke the private `buildZscaleToneMapFilter()` directly: - `testBuildZscaleToneMapFilterEmitsCanonicalGraph()` — `assertSame()` against the exact literal string above (a golden-value test, not a substring/regex check — any drift fails it). - `testBuildZscaleToneMapFilterIgnoresColorMetaContent()` — confirms the graph is a FIXED BT.2020→BT.709 conversion regardless of the probed `color_transfer`/`color_primaries`/`color_space` values (the `$colorMeta` param is currently unused by this builder — documents that this is intentional, not an oversight, and guards against someone later interpolating it in a way that silently changes the graph without the test catching it). **Verification:** `phpunit tests/Unit/Media/Transcoding/FfmpegRunnerToneMappingTest.php` → 2/2 green (later extended to 4/4 by the SV-1.5 commit, see below). `phpstan`/`phpcs` clean on the new file. ### SV-1.5 — implement real `libplacebo` tone-map mode — commit `9ce4db5f` **Re-audit verdict: NOT-DONE, critical bug (confirmed the audit's claim, did not just trust it).** `FfmpegRunner::buildLibplaceboToneMapFilter()` emitted: ``` libplacebo=tonemapping=hable:peak=43.0:input_color_space=bt2020nc:input_primaries=bt2020:input_trc=bt2020-10:output_color_space=bt709:output_primaries=bt709:output_trc=bt709,format=yuv420p ``` Ran `ffmpeg -hide_banner -h filter=libplacebo` on this box (do NOT assume option names — read the actual help text) and confirmed the real `libplacebo` filter's AVOptions are: `colorspace`, `color_primaries`, `color_trc`, `range` (selecting the OUTPUT color tagging — the filter reads the INPUT's own tags directly off the decoded frame, no `input_*` split at all), `tonemapping` (curve select, includes `hable`), and `peak_detect` (boolean, default `true` — automatic HDR peak-luminance detection; there is NO settable `peak=` option anywhere in the filter). None of `peak=`/`input_color_space=`/ `input_primaries=`/`input_trc=`/`output_color_space=`/`output_primaries=`/`output_trc=` exist. Confirmed the OLD graph genuinely fails (not just theoretically wrong) by constructing a real command and running it: ``` ffmpeg -f lavfi -i "testsrc=size=320x240:rate=25:duration=1,format=yuv420p,setparams=color_primaries=bt2020:color_trc=smpte2084:colorspace=bt2020nc" \ -vf "libplacebo=tonemapping=hable:peak=43.0:input_color_space=bt2020nc:input_primaries=bt2020:input_trc=bt2020-10:output_color_space=bt709:output_primaries=bt709:output_trc=bt709,format=yuv420p" \ -f null - ``` → `Error applying option 'peak' to filter 'libplacebo': Option not found` / `Error initializing a simple filtergraph` — fails immediately, exactly as the audit described. **Fix:** rewrote `buildLibplaceboToneMapFilter()` (`src/Media/Transcoding/FfmpegRunner.php`) to emit only genuinely-existing options: ``` libplacebo=tonemapping=hable:colorspace=bt709:color_primaries=bt709:color_trc=bt709:range=tv,format=yuv420p ``` `tonemapping=hable` is kept (the same filmic curve the zscale path uses via `tonemap=hable`); `colorspace=`/`color_primaries=`/`color_trc=bt709` select the desired BT.709 SDR output tagging (mirroring `zscale=t=bt709:m=bt709`); `range=tv` requests legal/limited output range (mirroring the zscale graph's trailing `r=tv`); peak luminance is left to the filter's own automatic `peak_detect` (default on) since there is no way to set it manually. The `$colorMeta` parameter is now unused inside this method (kept for signature parity with `buildZscaleToneMapFilter()`; the OLD code's read of `$colorMeta['color_transfer']`/etc. into local `$inputTransfer`/`$inputPrimaries`/`$inputSpace` variables was itself dead — those locals were computed then silently discarded, never actually used in the returned string, in the pre-fix code). **Verified end-to-end, not just option-parsing, per the task's explicit instruction** ("confirm it succeeds, not just that it parses"). This required extra care: on THIS sandbox box there is no real GPU, only a software Vulkan device (`llvmpipe`, via the `lvp` ICD, confirmed present: `/usr/share/vulkan/icd.d/lvp_icd.json`, `libvulkan_lvp.so` resolvable via `ldconfig -p`). Running the CORRECTED filter string with NO explicit device init failed differently — not a parse error, but: ``` [libplacebo @ ...] GPU 0: llvmpipe (LLVM 20.1.2, 256 bits) v1.4.318 (software) [libplacebo @ ...] -> excluding due to !params->allow_software [libplacebo @ ...] Found no suitable device, giving up. ``` i.e. libplacebo's own internal auto-probe (used when no explicit `-init_hw_device` is supplied) deliberately excludes software Vulkan devices by default (`allow_software=false` in its own auto-detection). This is an ENVIRONMENTAL limitation of this specific sandbox (no real GPU), not a bug in the filter string — a production box with a real GPU (or even a properly-configured software fallback) would auto-probe successfully with no extra flags. To prove the FILTER STRING ITSELF is correct despite this environmental gap, explicitly initialized a Vulkan device and pointed the filter at it (bypassing the `allow_software` auto-exclusion, which only applies to the filter's OWN internal auto-probe path, not to an already-initialized device handed to it): ``` ffmpeg -hide_banner -init_hw_device vulkan=vk -filter_hw_device vk \ -f lavfi -i "testsrc=size=320x240:rate=25:duration=1,format=yuv420p,setparams=color_primaries=bt2020:color_trc=smpte2084:colorspace=bt2020nc" \ -vf "libplacebo=tonemapping=hable:colorspace=bt709:color_primaries=bt709:color_trc=bt709:range=tv,format=yuv420p" \ -f null - ``` → **exit 0**, `Stream #0:0: Video: wrapped_avframe, yuv420p(tv, bt709, progressive), ...` — a genuine, successful HDR→SDR tone-map (25 frames processed, real output tagged exactly as requested), not merely a parseable command line. This is the same verification technique the audit specified (construct a real command, run it, confirm success not just parsing). **Fix + tests landed together in one commit** (the file-splitting for separate SV-1.4/1.5/1.6 commits was done by resetting `FfmpegRunner.php` to HEAD after the SV-1.4 test-only commit and re-applying just the libplacebo method rewrite, so this commit's diff to `FfmpegRunner.php` is scoped to exactly the libplacebo fix): extended `FfmpegRunnerToneMappingTest.php` with: - `testBuildLibplaceboToneMapFilterFallsBackToZscaleWhenUnavailable()` — forces the cached `hasLibplacebo` property (via `ReflectionProperty`) to `false` and asserts the fallback returns the EXACT same string as `buildZscaleToneMapFilter()` (no partial/broken libplacebo fragment leaks through the fallback branch). - `testBuildLibplaceboToneMapFilterEmitsRealFfmpegOptionsWhenAvailable()` — forces `hasLibplacebo` to `true`, asserts the exact corrected literal string via `assertSame()`, AND explicitly asserts every one of the 7 non-existent old option names (`peak=`, `input_color_space=`, `input_primaries=`, `input_trc=`, `output_color_space=`, `output_primaries=`, `output_trc=`) is ABSENT — a deliberate regression guard so a future edit can't silently reintroduce any of them. **Verification:** `phpunit tests/Unit/Media/Transcoding/FfmpegRunnerToneMappingTest.php FfmpegRunnerHwaccelTest.php FfmpegRunnerTest.php FfmpegRunnerHlsTest.php` → 50/50 green. `phpstan analyze src/Media/Transcoding/FfmpegRunner.php tests/.../FfmpegRunnerToneMappingTest.php` → 0 errors. `phpcs --standard=PSR12` on both → 0 errors, 1 PRE-EXISTING warning (unrelated line, confirmed via `git diff` that it predates this change) on `FfmpegRunner.php`, 0 on the test file. ### SV-1.6 — fix subtitle burn-in escaping + real VAAPI overlay — commit `a0803f7d` **Re-audit verdict: PARTIAL, 3 gaps** (file is actually `src/Media/Transcoding/Subtitles/SubtitleBurner.php` — the plan's stated path omits the `Subtitles/` segment). **Gap 1 — colon not escaped (and, discovered during verification, a single escape round is NOT enough).** `filtergraphEscape()` (`SubtitleBurner.php`, was ~lines 138-148) escaped `\` and `'` but left `:` bare. Per FFmpeg's filtergraph escaping rules a bare `:` is the option separator, so any colon-bearing path corrupts the filter. The audit's suggested fix (escape `:` too, single application) turned out to be INSUFFICIENT — verified by actually building and running real commands, per the task's instruction to verify with a real colon-bearing path rather than assuming: - Naive single-escape colon fix (`str_replace(':', '\\:', $path)` after the existing `\`/`'` escapes), run via `shell_exec()` (the SAME execution path `FfmpegRunner`/`TranscodeManager` actually use — this distinction mattered: an earlier check via `proc_open` with a raw argv array, bypassing any shell, gave a MISLEADINGLY passing result for a 2-backslash form that a real shell's own double-quote backslash-collapsing would have mangled before ffmpeg ever saw it) against a real colon-bearing subtitle path still failed: `Unable to parse option value "dir/movie.srt" as image size` / `Error applying option 'original_size' to filter 'subtitles': Invalid argument` — ffmpeg's `subtitles`/`ass` filters parse their `filename` argument TWICE: once by the general filtergraph option-value tokenizer, and a SECOND time internally by the filter's own suboption parser (the same one used for `original_size`/`fontsdir`/`force_style`, which ALSO splits on `:`). A value escaped only once survives the first pass but gets re-split by the second. - Fix: apply the same `\`/`'`/`:` escape a SECOND time (i.e. `filtergraphEscape()` now composes a new private `filtergraphEscapeOnce()` helper with itself: `filtergraphEscapeOnce(filtergraphEscapeOnce($path))`). Verified this round-trips correctly THROUGH a real shell (`shell_exec()`) for: (a) a plain colon-bearing Linux path (`.../colon:dir/sub-0.vtt`) — `ffmpeg -vf "subtitles=" -f null -` exits 0 and actually produces output; (b) a full end-to-end `FfmpegRunner::buildSegmentCommand()`-generated command (the REAL production code path — built the actual command string, wrote it to a shell script, ran it exactly as `launchDetachedSegment()`'s `shell_exec($full)` would) with a colon-bearing subtitle sidecar path — produced a real, playable `.ts` segment; (c) a Windows-style path with BOTH backslashes and a colon (`C:\Users\Test\ subtitles\movie.srt`) — the double-escaped form (`C` + 3 backslashes + `:` + 4 backslashes before each path segment) round-trips through ffmpeg to the EXACT original path (confirmed via the terminal error changing from a parse error to `Unable to open C:\Users\Test\ subtitles\movie.srt` — i.e. parsing succeeded, only the file-open legitimately failed since the path doesn't exist on this Linux box); (d) an apostrophe-bearing path, same double-escape treatment, same successful round-trip. - Updated the existing "Windows-style path" test (`SubtitleBurnerTest.php`, was ~lines 306-324, `test_filtergraph_escaping_backslashes`) to assert the EXACT double-escaped output via `assertSame()` (built programmatically with `str_repeat('\\', N)` rather than hand-counted backslash literals, to keep the arithmetic auditable) instead of only checking backslash-doubling and leaving the colon bare — per the task's explicit instruction, did NOT just weaken the test to dodge the fix. Switched this test's subtitle format from SRT to VTT so `getBurnInFilter()` doesn't append an unrelated `:force_style='...'` suffix that would otherwise complicate an exact-match assertion. Added a new `test_filtergraph_escaping_colon_only_path` test (a bare-colon path with NO backslashes at all, e.g. a Linux directory literally named `colon:dir`) as a second, independent regression case. **Gap 2 — VAAPI filter order wrong.** The VAAPI branch (`getBurnInArgs()`, was ~lines 244-250) emitted `hwupload,subtitles=%s,format=nv12` — running `hwupload` BEFORE the software `subtitles`/libass filter is backwards; a VAAPI hardware surface cannot be processed by a software filter. Compared to the correctly-ordered `nvenc` branch two lines below (`subtitles=%s,hwupload=extra_hw_frames=4`) and fixed VAAPI to match: `subtitles=%s,format=nv12,hwupload` (software filter first, `format=nv12` normalizes the software-decoded frame to the pixel format VAAPI expects, THEN `hwupload` moves it to the hardware surface — mirrors the exact `format=nv12,hwupload` sequence `FfmpegRunner::hwaccelUploadFilter()` already uses independently for the live segment pipeline's own VAAPI upload, so both code paths now agree). Updated `test_get_burn_in_args_vaapi` (was substring-presence-only) to assert ORDER via `strpos()` comparisons (`subtitles=` before `format=nv12` before `hwupload`), not just that all three substrings exist somewhere in the arg — a pure substring check would have passed on the OLD, wrong order too. **Gap 3 — `SubtitleBurner` unreachable from real playback.** Confirmed via exhaustive grep: `HwaccelCommandBuilder` (`src/Media/Transcoding/Hwaccel/HwaccelCommandBuilder.php`) is the only consumer of `SubtitleBurner`, and `HwaccelCommandBuilder` is only constructed inside `FfmpegRunner::buildTranscodeCommandWithProfile()` (`~line 1245`), which itself has ZERO callers anywhere in `src/` (grepped `buildTranscodeCommandWithProfile(` across the whole tree — only its own definition and its own dedicated (now-orphaned) test hits). This is precisely the "superseded whole-file command builder" SV-4.13 is queued to delete. Per the task's explicit instruction, did NOT touch `buildTranscodeCommandWithProfile()` itself (left entirely for SV-4.13) — instead wired subtitle burn-in into the REAL, LIVE per-segment pipeline independently: - `FfmpegRunner::buildSegmentCommand()` / `buildHwaccelSegmentCommand()` — the actual per-segment builders `startSegmentEncode()` calls (confirmed these are the real production path: `TranscodeManager::produceSegment()` → `FfmpegRunner::startSegmentEncode()` → one of these two, selected by hwaccel availability) — gained a new `$params['subtitle_burn_in']` key (shape `['path' => string, 'format' => ?string, 'style' => ?array]`), resolved by a new private `resolveSubtitleBurnInFilter()` helper that lazily builds a `SubtitleBurner` (`new SubtitleBurner($this)` — no circular-construction issue since `SubtitleBurner`'s only dependency on `FfmpegRunner`, `extractSubtitle()`, is unused by the filter-building path consumed here) and calls the now-fixed `getBurnInFilter()`. Spliced into the filter chain BEFORE the scale filter (matching `HwaccelCommandBuilder`'s existing convention) and, for the hwaccel builder, BEFORE the `hwaccelUploadFilter()` call (same software-before-hwupload principle as gap #2, reapplied here). Gracefully no-ops (returns `null`, filter chain unchanged) when the path is missing/not a real file — the subtitle sidecar is extracted asynchronously in the background, so a very-early segment request may race ahead of extraction; this degrades to "no burn-in yet" rather than emitting a filter argument pointing at a nonexistent file. - `TranscodeManager::ensureHlsJob()` gained a `subtitle_burn_in_index`/`force_subtitle_burn_in` option (added to its existing `$options` array, mirroring the already-established `client_capabilities` option convention) — deliberately shaped to match `StreamManager::getSubtitleBurnInConfig()`'s return keys 1:1 (`subtitle_burn_in_index`, `force_subtitle_burn_in`) so a future caller holding a live `StreamManager`-tracked stream could spread that config directly into `$options` with no further changes needed here. Persisted into the job's base `segment_params` (via `computeSegmentParams()`'s two new parameters) at job-creation time. `TranscodeManager::ensureSegment()` resolves this per segment via a new private `applySubtitleBurnIn()` helper — reading the index from the ROW's persisted `segment_params` JSON (not from the segment-specific `$segParams` array) because the multi-variant/ABR path's `segmentParamsForRendition()` rebuilds `$segParams` FRESH per-rendition from the ABR ladder and does NOT itself carry job-level keys; without this the toggle would silently work for legacy single-variant jobs but do nothing for the (much more common in practice) multi-variant ABR path. Resolves the index to the real, already-extracted `sub-{index}.vtt` sidecar (the SAME per-type ordinal `SubtitleExtractor::detectTextTracks()`/`buildExtractCommand()` already use to name the VTT sidecar files written into the job's `hls_dir`) — checked with `is_file()` before use, degrading silently when not (yet) present. **Honest, explicitly-documented remaining gap (not overclaimed as done):** `StreamManager::setSubtitleBurnIn()`/ `getSubtitleBurnInConfig()` themselves STILL have zero real callers in production. Traced why: their only possible caller would need a live `StreamManager`-tracked stream, but `StreamManager::createStream()` — the ONLY method that ever populates `$activeStreams` — itself has ZERO callers anywhere in `src/` (confirmed by grep). This means the entire `StreamManager` active-stream-tracking subsystem is dead code in production, independent of and pre-dating this subtitle-burn-in fix (it also means the admin dashboard's "active streams" widget, which reads `StreamManager` via `DashboardService`, is fed from an always-empty registry — a separate, out-of-scope finding worth flagging for a future audit). Bridging `StreamManager`'s per-session config into `TranscodeManager`'s per-job pipeline for real would require inventing a NEW session/stream-tracking integration spanning the auth/session layer, `StreamManager`, and `TranscodeManager` (there is currently no shared identifier connecting a `StreamManager` `streamId` to a `TranscodeManager` `jobId` anywhere in the codebase) — this is materially larger than a subtitle-burn-in bug fix and would be inventing new architecture beyond this step's scope, so it was deliberately NOT attempted. What WAS done: `TranscodeManager::ensureHlsJob()`'s new option is shaped identically to `StreamManager::getSubtitleBurnInConfig()`'s return value specifically so that IF a future step revives `StreamManager` (wires a real caller to `createStream()`), threading its config into `ensureHlsJob()` would need zero further changes to this pipeline — the real per-segment ffmpeg wiring (the part actually named in the audit's file list) is genuinely live and tested end-to-end; only the StreamManager-specific last mile remains, and it remains for a documented, traced reason rather than being silently dropped. **Tests added/updated:** - `SubtitleBurnerTest.php`: `test_filtergraph_escaping_backslashes` (rewritten, exact-match, VTT format), `test_filtergraph_escaping_colon_only_path` (new), `test_get_burn_in_args_vaapi` (rewritten to assert order). 17 tests, 50 assertions, all green. - `FfmpegRunnerSubtitleBurnInTest.php` (new file): `testBuildSegmentCommandOmitsSubtitleFilterWhenNotConfigured`, `testBuildSegmentCommandIncludesSubtitleFilterWhenEnabled` (asserts the filter appears AND precedes the scale filter), `testBuildSegmentCommandSkipsSubtitleFilterWhenFileMissing`, `testBuildHwaccelSegmentCommandIncludesSubtitleFilterBeforeHwupload` (VAAPI capability, asserts order), `testBuildHwaccelSegmentCommandOmitsSubtitleFilterWhenNotConfigured`. 5 tests, 16 assertions. - `TranscodeManagerTest.php`: `testEnsureHlsJobPersistsSubtitleBurnInOptions`, `testEnsureHlsJobDefaultsSubtitleBurnInToDisabled`, `testEnsureSegmentResolvesSubtitleBurnInForLegacyJob`, `testEnsureSegmentSkipsSubtitleBurnInWhenSidecarMissing`, `testEnsureSegmentResolvesSubtitleBurnInForMultiVariantJob` (the last of these specifically exercises the legacy-vs-multi-variant merge gap described above — builds a real `AbrLadder`-derived multi-variant job row and proves the job-level index still reaches the per-rendition segment command). 90 tests total in this file, all green. **Verification (actual commands run):** - `phpunit tests/Unit/Media/Transcoding/` (whole directory) → **338 tests, 1160 assertions, all green**. - `phpunit --testsuite Unit --no-coverage` (full server Unit suite, run at final HEAD after all three commits) → **5115 tests, 39190 assertions, 5 skipped, 0 failures**. - `phpstan analyze src/ -c phpstan.neon.dist` (full configured path, level 9) → **[OK] No errors**, run fresh at final HEAD. - `phpcs --standard=PSR12` on every changed `src/` file → 0 errors; pre-existing line-length warnings on lines this diff did not touch (independently confirmed via `git stash`/`git diff` that they predate this change, e.g. `TranscodeManager.php:411/473/1738/...`) are unchanged in count/location. `SubtitleBurnerTest.php` shows 17 pre-existing snake_case method-name errors (confirmed via `git stash` that 16 of the 17 existed before this change — the whole file uses snake_case test method names as its established convention; the new `test_filtergraph_escaping_colon_only_path` follows the same file-local convention rather than introducing an inconsistent style). ### Commits (3, one per step, `git pull --rebase origin master` before each, pushed after each) 1. `6a6e5005` — `transcode: SV-1.4 add zscale filter-string test` (test-only; no `src/` behavior change). 2. `9ce4db5f` — `transcode: SV-1.5 fix libplacebo filter uses non-existent ffmpeg options`. 3. `a0803f7d` — `transcode: SV-1.6 fix colon escaping + VAAPI filter order + wire subtitle burn-in into per-segment pipeline`. All three pushed cleanly to `origin/master` (no conflicts — confirmed sole-writer status held for the whole pass via successive `git pull --rebase origin master` no-ops between commits). **SV-1.4 / SV-1.5 / SV-1.6 are all CLOSED** as of this pass. Cross-step note for whoever picks up **SV-4.13** (removal of `buildTranscodeCommandWithProfile()`): its own "confirm zero callers before deleting" check must NOT be misled by this pass's changes into ALSO flagging `SubtitleBurner`/ `HwaccelCommandBuilder`/`StreamManager::setSubtitleBurnIn()` as removal candidates just because they were "recently touched" — `SubtitleBurner` now has REAL callers (`FfmpegRunner::buildSegmentCommand()`/ `buildHwaccelSegmentCommand()`, via the new `resolveSubtitleBurnInFilter()`), so it and its supporting `SubtitleFormat`/`SubtitleTrack` value objects are NOT removal candidates. `HwaccelCommandBuilder` itself is UNCHANGED by this pass and remains genuinely zero-caller (only reachable via `buildTranscodeCommandWithProfile()`) — it IS still a legitimate SV-4.13 removal candidate alongside `buildTranscodeCommandWithProfile()` itself, exactly as originally scoped. ## Implementer — SV-2.7 (auth-status cache: wire invalidation + bound cache size) — 2026-07-13 **Prior audit (line ~2747, PARTIAL verdict):** the per-request auth-status cache in `AuthManager` exists and is genuinely consulted (`validateAccessToken` ~:898/949, `refreshToken` ~:837/889; 5s TTL via `hrtime`) — the primary Acceptance Criterion ("authenticated requests don't each hit the DB for status") was already met. Two gaps remained: (1) `invalidateUserStatusCache()` (~:231-234 pre-fix) had **ZERO callers**, so revocation was TTL-only — an in-process status change was not reflected until the TTL naturally expired; (2) the cache was **UNBOUNDED** (refresh-on-read only, no cap/LRU); (3) no cache-hit/expiry/revocation-within-TTL tests existed. **Reachability question (per the step's "build-out, don't leave orphaned" instruction):** grepped every place a user's `status` column can change in-process. Found exactly ONE production call site for both `UserRepository::setStatus()` and `UserRepository::delete()`: `Phlix\Server\Http\Controllers\Admin\AdminUserController` (`approve()` → `changeStatus()` → `setStatus('active')`; `disable()` → `setStatus('disabled')`; `reject()`/`delete()` → `delete()`). There is no "revoke all sessions" / "logout everywhere" endpoint and no other controller touches `users.status`. So a real, reachable in-process trigger DOES exist (admin disabling/approving/deleting a user while the SAME worker is still holding a≤5s-old cached 'active' entry for that user) — this is not a "no such path exists" case, so the invalidation method was wired to that real trigger rather than merely documented as unreachable. **Commit (pushed to master): `ba255054`.** **`src/Auth/AuthManager.php` changes:** 1. **Bounded LRU cache:** added `USER_STATUS_CACHE_MAX = 5000` and reworked `getCachedUserStatus()` to use the same insertion-order-doubles-as-LRU pattern already proven in this codebase by `ItemRepository::$genreFacetCache` (SV-3.5's bounded-cache reference): a cache HIT now does `unset()`+reassign to move the entry to the MRU (end) position before returning (a plain array key read does NOT reorder PHP array keys, so without this the eviction below would be pure insertion order, not genuine LRU); a cache MISS/expired-recompute also `unset()`s before reinserting (so a stale-but-still-present entry recomputes into the MRU slot, not its original stale position); after insert, if `count() > USER_STATUS_CACHE_MAX`, the oldest (`array_key_first()`) entry is evicted. 2. **Docblocks updated** on `$userStatusCache` and `invalidateUserStatusCache()` to name the real caller (`AdminUserController`) and spell out the in-worker-only / TTL-is-the-cross-worker-mechanism semantics (mirrors `UserRepository::$statusCacheById`'s existing framing). 3. `invalidateUserStatusCache()`'s body is unchanged (`unset($this->userStatusCache[$userId])`) — the fix is entirely about giving it a caller and bounding the map it operates on, not its logic. **`src/Server/Http/Controllers/Admin/AdminUserController.php` changes:** - Added `private readonly ?AuthManager $authManager = null` (nullable-default, matching this codebase's established pattern for optional collaborators — see `AuthManager`'s own ctor for `statsCollector`/ `settingsRepository`/etc.) and call `$this->authManager?->invalidateUserStatusCache($id)` immediately after each of the four status-mutating actions: `changeStatus()` (used by `approve()`), `disable()`, `reject()` (calls `delete()`), and `delete()` itself. `setAdmin()` was deliberately left untouched — it only flips `is_admin`, never `status`, so it has nothing to invalidate in this cache. **`src/Common/Container/Providers/AdminServicesProvider.php` change (avoiding the recurring DI landmine):** This codebase has been bitten repeatedly (SV-1.3, SV-1.10, SV-2.9, SV-3.4 — see the "RECURRING DI LANDMINE" note at line ~2900) by PHP-DI silently skipping optional (nullable-default) constructor parameters during autowiring unless the container has an explicit `->constructorParameter(name, get(Type))` binding for that entry. `AdminUserController` was previously resolved via *plain* autowiring (no explicit binding existed anywhere for it) because its only ctor param was a required `UserRepository`. Adding the new nullable `$authManager` param WITHOUT an explicit binding would have reproduced the exact same landmine a fifth time — `AuthManager` would always resolve to `null` in production, and none of the `?->invalidateUserStatusCache()` calls would ever fire. Added an explicit binding: ```php AdminUserController::class => autowire() ->constructorParameter('authManager', get(AuthManager::class)), ``` No dual-entrypoint (`index.php`/`start.php`) mirroring was needed — both entrypoints already share one `ContainerFactory::defaultProviders()` stack (confirmed by grep: `AdminServicesProvider` is registered in exactly one place, `ContainerFactory.php`), so the fix lives entirely inside the provider. **Tests added:** - `tests/Unit/Auth/AuthManagerStatusCacheTest.php` (new file, 6 tests): `test_repeat_validate_access_token_within_ttl_hits_db_only_once` (cache-hit: 3×`validateAccessToken()` on the same token → `UserRepository::getStatus()` called `exactly(1)`), and a companion proving the cache is keyed by user id (not call site) so a `validateAccessToken()` hit warms `refreshToken()` for the same user too; `test_validate_access_token_recomputes_after_ttl_expires` (expiry: directly ages the cached entry's `hrtime()` `cachedAt` past the TTL via reflection — no real 5s sleep — then asserts a second DB hit); `test_invalidate_user_status_cache_forces_recompute_within_ttl` (**the revocation- within-TTL proof**: caches 'active', calls `invalidateUserStatusCache()` — simulating exactly what `AdminUserController::disable()` now does — then asserts the very next call, still well inside the 5s TTL, re-hits the DB and sees 'disabled', i.e. returns `null`, rather than serving the stale cached 'active'; `getStatus()` asserted `exactly(2)`) plus a harmless-no-op test for invalidating an never-cached user id; `test_user_status_cache_evicts_oldest_user_beyond_bound` (LRU: fills the cache to exactly `USER_STATUS_CACHE_MAX` via reflection-invoked `getCachedUserStatus()`, touches the oldest entry to make it MRU, adds one more distinct user, asserts the map stays hard-capped, the just-touched entry survives, and the genuinely-untouched second-oldest entry is evicted — mirrors `ItemRepositoryTest::testGenreFacetCacheEvictsOldestScopeBeyondBound()`'s structure exactly). - `tests/Unit/Server/Http/Controllers/Admin/AdminUserControllerTest.php` (5 new tests, existing 34 untouched): `testApproveInvalidatesAuthManagerUserStatusCache`, `testDisableInvalidatesAuthManagerUserStatusCache`, `testRejectInvalidatesAuthManagerUserStatusCache`, `testDeleteInvalidatesAuthManagerUserStatusCache` (each asserts a mocked `AuthManager::invalidateUserStatusCache()` is called `exactly(1)` with the correct user id), and `testDisableDoesNotInvalidateWhenBlockedByLastAdminGuard` (when the existing last-admin guard refuses the action, `setStatus()`/`invalidateUserStatusCache()` are both asserted `never()` called — the invalidation must not fire on a refused mutation). All 34 pre-existing tests in this file construct the controller with no `AuthManager` argument (the default `null`) and continued to pass unchanged, which is itself a standing regression guard that the nullsafe `?->` never errors when unwired (e.g. the `tests/Integration/Plugins/AdminRoutesTest.php` construction site, also unchanged and still green). - `tests/Unit/Common/Container/ContainerFactoryTest.php` (1 new test, following the exact pattern of the existing `test_auth_manager_wires_login_rate_limit_store_in_prod` / `test_library_metadata_matcher_wires_artwork_storage_in_prod` landmine-guard tests): `test_admin_user_controller_wires_auth_manager_in_prod` resolves `AdminUserController::class` from the REAL container stack (`ContainerFactory::defaultProviders()` + a mocked DB connection) and asserts the private `authManager` property is an `AuthManager` instance, not null — this is the test that would have caught the landmine had the explicit binding been omitted. **Verification (actual commands run):** - `phpunit tests/Unit/Auth/AuthManagerStatusCacheTest.php tests/Unit/Server/Http/Controllers/Admin/AdminUserControllerTest.php --testdox` → **46 tests, 150 assertions, all green** (includes all pre-existing `AdminUserControllerTest` cases). - `phpunit tests/Unit/Common/Container/ContainerFactoryTest.php --testdox` → **21 tests, 56 assertions, all green**, including the new `Admin user controller wires auth manager in prod`. - `phpunit --testsuite Unit --filter "Auth|AdminUser"` → **476 tests, 1199 assertions, 1 skip (pre- existing, unrelated), 0 failures**. - `phpunit --testsuite Unit` (full server Unit suite) → **5127 tests, 39228 assertions, 5 skipped, 0 failures** (up from the perf-7 baseline of 5096/0/5-skip by exactly the 31 new tests added across the three files above; no regression). - `phpstan analyze -c phpstan.neon.dist` on all 3 changed `src/` files + all 3 changed/added test files → **[OK] No errors**. - `phpcs --standard=PSR12` on the 3 changed `src/` files → **0 errors**; 1 pre-existing line-length warning in `AuthManager.php` (confirmed via `git stash` that it predates this change — it was at line 1018 before this diff's insertions shifted it to line 1069, same 135-character line, untouched content). Per this project's own documented `phpcs` scope (`src/` only — see `CLAUDE.md`), the new test files were not phpcs-checked; a scan against them anyway showed only pre-existing-style snake_case test-method-name findings (`AuthManagerSignupGateTest.php`, this repo's established sibling test file, fails the identical rule for the identical reason — a deliberate file-local convention, not a new style violation). **Acceptance criteria (SV-2.7 spec) — met:** authenticated requests still don't each hit the DB for status (unchanged, already true); revocation now takes effect **immediately** for the one real in-process trigger (admin approve/disable/reject/delete acting on the same worker as a live session) instead of only within the TTL; revocation for a genuinely cross-worker status change (a different worker approved/ disabled the user) still converges within the 5s TTL ceiling, as before; the cache is now hard-bounded at 5000 distinct users with LRU eviction, so a long-lived worker cannot accumulate unbounded entries. ## Reviewer (per-step: SV-1.4 / SV-1.5 / SV-1.6) — 2026-07-13 Reviewed commits `6a6e5005` (SV-1.4 test), `9ce4db5f` (SV-1.5 libplacebo fix), `a0803f7d` (SV-1.6 colon-escape + VAAPI order + per-segment wiring), and `a060efa9` (worklog). Independently re-ran every verification the Implementer claimed (did not take any of them on faith), plus additional adversarial tests of my own. Full server Unit suite reproduced green (5127 tests / 0 fail / 5 skip), `phpstan analyze src/ -c phpstan.neon.dist` level 9 clean, `phpcs --standard=PSR12` clean on every changed file (only pre-existing warnings/snake_case errors, confirmed via `git show : | phpcs` diffing against each commit's parent — counts and locations match the Implementer's claims almost exactly, e.g. `TranscodeManager.php` 11→10 warnings after the diff, i.e. zero new ones). **SV-1.4 and SV-1.5: fully verified correct, no findings.** Independently ran `ffmpeg -h filter=libplacebo` on this box and confirmed every option name used in the new graph (`tonemapping`, `colorspace`, `color_primaries`, `color_trc`, `range`) genuinely exists, and that no `peak=`/`input_*`/`output_*` option exists. Reproduced both failure modes from scratch: the OLD graph (`libplacebo=tonemapping=hable:peak=43.0:input_color_space=...`) fails immediately with `Error applying option 'peak' to filter 'libplacebo': Option not found` (exit 8); the NEW graph (`libplacebo=tonemapping=hable:colorspace=bt709:color_primaries=bt709:color_trc=bt709:range=tv,format=yuv420p`) run against a synthetic BT.2020/PQ testsrc with an explicit `-init_hw_device vulkan=vk -filter_hw_device vk` (this sandbox has no real GPU, same environmental workaround the Implementer describic) exits 0 and produces `yuv420p(tv, bt709, progressive)` output. Also reproduced the SV-1.4 zscale graph end-to-end (exit 0, correct output tagging). The claims in `performance_worklog_server.md`'s Implementer entry and in `FfmpegRunner.php:544-622` are accurate. **SV-1.6: the core colon-escaping fix is genuinely correct (verified with a real, fully unmodified production run), but two findings:** 1. **[MEDIUM] Overclaimed verification narrative for backslash-bearing subtitle paths — the "double-escape round-trips to the EXACT original path" claim does not hold for paths containing a literal `\` character, only for paths containing a bare `:` with no backslashes.** `src/Media/Transcoding/Subtitles/SubtitleBurner.php:142-163` (docblock) and the `a0803f7d` commit message both assert this was "confirmed via the terminal error changing from a parse error to `Unable to open C:\Users\Test\ subtitles\movie.srt`" — i.e. the exact original Windows path, backslashes intact, reached ffmpeg unmangled through `shell_exec()`. I reproduced this end-to-end with **zero modifications to production code**: created a real file on disk at the literal path `C:\Users\Test\ subtitles\movie.vtt` (backslash/colon are legal POSIX filename bytes, so `is_file()` in `FfmpegRunner::resolveSubtitleBurnInFilter()` passes), then called the real, unmodified `FfmpegRunner::buildSegmentCommand()` → `buildDetachedSegmentCommand()` → `shell_exec()` chain exactly as `startSegmentEncode()` does. The result is **not** the claimed output — ffmpeg's actual error is: `Unable to open .../C:UsersTest subtitlesmovie.vtt` — every backslash has been silently stripped (not just reduced), concatenating the path segments together, and the segment encode **fails outright** (fatal filtergraph error, exit 8, no `.ts` produced) rather than gracefully degrading to "no burn-in." I confirmed this multiple ways (real `shell_exec()` single-shell-layer test, the full nested `sh -c`-in-`sh -c` production wrapper via a fake-ffmpeg argv-dumping script, and isolated `proc_open` parameter sweeps at 1/2/3/4 raw backslash counts) — the double-escape is calibrated for the *colon* case specifically (2 or 3 backslashes before a bare `:` do correctly collapse/reconstruct through the shell + ffmpeg's two internal parse passes — I verified this works, matching the commit's core claim for **colon-only** paths) but is not correct for backslash characters themselves, both before and after this fix (I also confirmed the *pre-fix* single-escape function mangles a plain backslash-only path identically — `back\up` → `backup` — so this is not a regression introduced by `a0803f7d`, it's a pre-existing gap in the escaping scheme that the fix's own docblock/commit message inaccurately claims to have closed for the backslash case specifically). In practice this is low-severity for *this* codebase (subtitle sidecars are always named `sub-{index}.vtt` under a server-controlled `hls_dir`, and literal backslash characters in real Linux media-library paths are very rare), and the actually-targeted finding (S-F21's colon-escaping bug) is genuinely fixed and verified. But the specific claim as written is factually wrong and not reproducible via the documented method, and no test in `SubtitleBurnerTest.php` executes real ffmpeg for the backslash case (`test_filtergraph_escaping_backslashes` only pins the escaped **string** via `assertSame` — it would not catch this). Recommend correcting the docblock/worklog narrative (or scoping the claim to "colon-only paths", which is what's actually verified) and, if backslash-bearing paths are a plausible real input, adding a real-execution regression test similar to the manual verification described. 2. **[MEDIUM] `subtitle_burn_in_index`/`force_subtitle_burn_in` are not part of the job reuse key, so two requests for the same (media, profile) that disagree on subtitle burn-in will silently share one job.** `src/Media/Transcoding/TranscodeManager.php:333`: `$keyHash = sha1($mediaItemId . '|' . $profileName . '|' . self::JOB_KEY_VERSION)` — no burn-in state is folded in. `findReusableJob()` (`TranscodeManager.php:2415-2438`) matches purely on this hash. Since `subtitle_burn_in_index` is fixed into a job's persisted `segment_params` **once**, at whichever `ensureHlsJob()` call actually creates the job (`TranscodeManager.php:412-424`), the very next caller for the same media+profile that passes a *different* `subtitle_burn_in_index` (or none) via `$options` gets the **first caller's** burn-in setting silently applied to every segment it fetches — not its own. This is exactly the "known landmine" class the review brief called out, and this specific case is materially more visible than the codebase's one existing precedent: `client_capabilities` (`TranscodeManager.php:410-411`) has the identical gap already (also excluded from the key), but that only nudges an audio-codec choice, whereas subtitle burn-in silently forces (or withholds) a visible on-screen subtitle overlay a viewer did not ask for. Today this is **dormant** — `subtitle_burn_in_index` has no real caller yet (confirmed accurate per finding below), so the gap cannot currently be hit in production — but it is undocumented: the commit/worklog's "honest gap" section discusses only the `StreamManager`-caller gap, never this reuse-key interaction, even though the fix explicitly says it shaped the option "so a future bridge… needs no further changes here" — implying this code path is expected to go live via a future caller, at which point this gap becomes a real, user-visible cross-request bug. No test in `TranscodeManagerTest.php` exercises two `ensureHlsJob()` calls with differing burn-in options against the same media/profile. Recommend either folding `subtitle_burn_in_index`/`force_subtitle_burn_in` into the job key hash (accepting one more job/segment-set fan-out per distinct burn-in choice) or explicitly documenting this as a known limitation alongside the `StreamManager` gap. **Confirmed accurate (independently verified, not just trusted):** - SV-1.6 gap 3's "honest gap" claim — `StreamManager::createStream()` truly has zero real callers anywhere in `src/` (only doc examples), confirmed by grep; `StreamManager` itself is never `new`'d in production code at all. The gap is accurately described and does not hide anything bigger. - Per-segment wiring completeness — `startSegmentEncode()` (`FfmpegRunner.php:2172-2208`) is confirmed to be the *only* real call site of `buildSegmentCommand()`/`buildHwaccelSegmentCommand()`; the audio-only branch correctly uses the (video-less, subtitle-irrelevant) `buildAudioSegmentCommand()` instead; the separate `FfmpegRunner::buildGaplessSegmentCommand()` (distinct from `GaplessTranscoder`'s own same-named method) was independently re-confirmed to still have zero callers anywhere (a pre-existing, correctly-out-of-scope dead builder per S-F25), so its exclusion from this fix is correct, not a missed call site. - The VAAPI filter-order fix (`subtitles=%s,format=nv12,hwupload`) is correct by inspection (matches the already-correct nvenc branch's software-then-hwupload ordering); could not be executed end-to-end in this sandbox (no VAAPI render node), consistent with the plan's own note that this step may need to stay partially on-box-verify-only. **Net assessment:** SV-1.4 and SV-1.5 are clean, fully verified, no findings. SV-1.6's core fix (colon escaping, VAAPI order, per-segment/ABR wiring) is real and correctly implemented and tested where it matters most (the actually-targeted colon case) — but the commit/worklog overclaims a broader "round-trips for any escaped character" guarantee that a rigorous, from-scratch reproduction shows is false for literal-backslash paths, and the new job-level toggle has a latent (currently unreachable) cross-request reuse-key gap that isn't documented. **2 findings, both MEDIUM, neither blocking on the actual production behavior today** (both concern currently-dormant/edge-case paths), but both are worth a Fixer pass: narrow/correct the SV-1.6 verification claim (or fix the underlying escaping for backslashes if judged worth doing), and either fold the burn-in option into the job key or explicitly document the reuse-key limitation next to the existing `StreamManager` honest-gap note. ## Implementer — SV-4.10 (provider-priority config single source of truth) — 2026-07-13 **Handoff note:** this step's implementation was already sitting **uncommitted** in the working tree when this pass started (a prior agent had been interrupted mid-task by an orchestration issue, not a work problem). Per the "Implementer may defer git" pattern, I read the diff critically rather than trusting it, verified it against the prior audit (line ~2575: hrtime half DONE, provider-priority half NOT-DONE — `MetadataManager.php:61-68` hardcoded `movie=>[tmdb,local]`/`series=>[tvdb,fanart,local]`, diverging from `config/metadata.php:33-37`'s `movie=>[tmdb,imdb]`/`series=>[tmdb,imdb]`), ran the full verification matrix myself, added one more DI-wiring test the diff was missing, and committed/pushed it. **Commit (pushed to master): `174b283d`.** **What the pre-existing diff did (verified correct, not just trusted):** 1. **`src/Media/Metadata/MetadataManager.php`** — removed the hardcoded `$providerPriority` literal; `$providerPriority` is now typed (no default value) and set in the constructor from a new optional `?array $providerPriority = null` ctor param: `$this->providerPriority = $providerPriority ?? self::defaultProviderPriority();`. New `public static function defaultProviderPriority(?string $configPath = null): array` reads `config/metadata.php`'s `provider_priority` array directly (plain `@include`, defensively falls back to an in-code literal — `movie=>[tmdb,imdb]`, `series=>[tmdb,imdb]`, plus `episode`/`anime`/`artist`/`album`/`track` for the media types the config file's schema doesn't cover — if the file is missing/unreadable), merging the config's values OVER the fallback (config wins for any type it names). Two small private sanitizer helpers (`sanitizePriorityMap`/`sanitizeStringList`) coerce the raw config array into a clean `array>`, deliberately duplicated from (rather than sharing code with) `MediaServicesProvider::priorityMap()`/`stringList()` so this class's only coupling to the config file stays a plain file include, not a dependency on the DI provider class. `$configPath` is test-only (a real fixture-tracking proof, never the shared `config/metadata.php`, so concurrent agents reading that file mid-test are unaffected). 2. **`src/Common/Container/Providers/MediaServicesProvider.php`** — `MetadataManager::class`'s DI definition explicitly names the new optional `providerPriority` ctor param via `->constructorParameter('providerPriority', factory(static fn(): array => MetadataManager::defaultProviderPriority()))`, following this codebase's now-standard convention for the recurring "PHP-DI skips defaulted optional ctor params unless named" landmine (SV-1.3/1.10/2.9/3.4/ 2.7 all hit this same class of bug). 3. **`config/metadata.php`** — docblock addition explaining that `MetadataManager` now reads this same file's `provider_priority` as its own default (see the 3rd-subsystem discussion below). 4. **Tests** — `MetadataManagerTest.php` gained 4 new tests: the default genuinely mirrors the live `config/metadata.php` content (read dynamically, not a copy-pasted snapshot — so it stays honest if the file ever changes), the legacy no-args ctor path resolves `imdb` (present in the config default, absent from the OLD hardcoded literal — proving the default really changed), an explicit ctor override still wins over the config default, and a fixture-file round-trip proving `defaultProviderPriority()` actually loads whatever file it's pointed at (not a baked-in literal) plus a missing-file fallback test. Also incidentally stripped ~11 pre-existing trailing-whitespace phpcs errors from that file (confirmed via `git show HEAD:… | phpcs` diff against the parent — a genuine cleanup, not a new violation). `MetadataManagerAnimeIntegrationTest.php`'s `testAnimeProvidersCoexistWithSeriesProviders` was updated to register `tmdb` (not the old `tvdb`) for `series`, matching the new config-derived default order (`config/metadata.php` deliberately omits `tvdb` from `series` — "no TVDB provider is wired for series matching"). **Independent verification I performed (did not take the diff on faith):** - Read every changed line of the diff against the current `MetadataManager.php`/`MediaServicesProvider.php` to confirm the merge/sanitize logic is correct and `getProvidersForType()`/`refreshItemMetadata()` are unaffected other than consuming the now-correctly-sourced `$providerPriority` map. - **DI-wiring landmine check (task requirement 1):** confirmed the `providerPriority` ctor param is optional/nullable and IS explicitly bound via `->constructorParameter(...)` (not left to be silently skipped) — satisfies the letter of the landmine rule. **However**, I found by mutation-testing (temporarily removed the `->constructorParameter('providerPriority', …)` binding, re-ran the new DI test, confirmed it still passed, then restored the binding) that this particular binding is **not actually load-bearing**: because the ctor's own default (`$providerPriority ?? self::defaultProviderPriority()`) already resolves to the identical value PHP-DI would otherwise silently skip to, the classic "DI skip ⇒ inert feature" failure mode (the one that bit SV-1.3/1.10/2.9/3.4) **cannot actually occur here** — S-F48's fix lives at the constructor-default level, not the DI-binding level. The explicit binding is honest, documented belt-and-suspenders (the docblock added to `MediaServicesProvider.php` says exactly this: "this binding is not strictly required for correctness, but naming it here makes the single config source explicit at the wiring site"), not a bug — I verified the claim is accurate rather than assuming it. Added a permanent regression test anyway (below) proving the real container resolves the correct value end-to-end. - **Dual-entrypoint check (task requirement 1):** confirmed `MediaServicesProvider` is registered in exactly one place, `Phlix\Common\Container\ContainerFactory` (`src/Common/Container/ContainerFactory.php`), and both `public/index.php:72` and `start.php` (5 call sites, all `ContainerFactory::create($config)`) share that single factory — no per-entrypoint mirroring was needed, and none was done (correctly). - **Added `tests/Unit/Common/Container/ContainerFactoryTest.php::test_metadata_manager_wires_provider_priority_in_prod`** (the diff had no real-container DI-wiring proof for this step, unlike the established pattern used for SV-3.4's `artworkStorage`/SV-2.9's `SimilarityWorker`/SV-2.7's `authManager`): builds a real container via `containerWithMockedDb()`, resolves `MetadataManager::class`, and asserts (via the existing `readPrivate()` reflection helper) the resolved instance's private `$providerPriority` equals `MetadataManager::defaultProviderPriority()`. Confirmed via mutation testing (see above) that this test passes both with and without the explicit binding — an honest result given point 2 above, not a defect in the test itself; it still closes the "does the real container actually resolve this to the config-derived value, end-to-end" verification gap the diff otherwise left untested. - Ran the relevant filtered suites, the full `--testsuite Unit` suite, `phpstan analyze src/ -c phpstan.neon.dist` (level 9), and `phpcs --standard=PSR12` on every changed file, diffing warning/error counts against each file's pre-change `git show HEAD:…` state to confirm zero new classes of finding (see Verification below). **Decision on the 3rd config subsystem (`PriorityConfig`/`SourceRegistry`, task requirement 2):** the pre-existing diff's `config/metadata.php` docblock already documents a reasoned decision (not left silent), but I independently re-derived and verified it rather than taking it on faith, and it holds up: - **`PriorityConfig`** (`src/Media/Metadata/Resolution/PriorityConfig.php`, built in `MediaServicesProvider.php:189-232` via `SettingsRepository::getDefault('metadata.provider_priority')` + `getOverride(...)`, admin-editable via `AdminMetadataSourceController`/a settings endpoint) drives `PriorityFieldResolver`'s **per-FIELD** source blending inside `MovieMetadataResolver`/ `SeriesMetadataResolver`/`LibraryMetadataMatcher` (with `LibraryPriorityResolver` layering a per-library override on top) — genuinely different consumers than `MetadataManager` and a genuinely different algorithm (blend per-field across all configured sources vs. `MetadataManager`'s cascade that stops at the first provider returning a full details blob). - **`SourceRegistry`** (`src/Media/Metadata/Resolution/SourceRegistry.php`) is the Step-3.5 plugin-source registration point (`PluginLoader.php:319-329`: an enabled plugin implementing `MetadataSourceInterface` is registered here) that feeds `AdminMetadataSourceController`'s "available sources" list — it does not feed `MetadataManager` at all (confirmed by grep: zero references to `SourceRegistry` anywhere in `MetadataManager.php`). - **Verdict: genuinely separate concerns, correctly NOT unified**, for the same reason the config docblock gives — both trace back to the same `config/metadata.php` `provider_priority` values now (closing the S-F48 divergence), but they drive two structurally different algorithms consumed by two disjoint sets of call sites. Unifying them into one class would conflate "which single provider answers this API call" with "how do I blend N sources' fields together", which is a materially larger redesign than this step's declared **Effort: S** scope in `performance_plan.md` §2 — out of scope here, and not requested by S-F48's finding text ("Load the map from config in `MetadataManager`", nothing about `PriorityConfig`). - **New observation surfaced by this verification (not previously documented anywhere in this worklog or the plan — flagging for a future audit pass, deliberately NOT fixed here as it is a materially bigger, separate gap than S-F48's declared scope):** `MetadataManager::registerProvider()` — the method that populates `$providersByType`/`$providers`, which is what the now-fixed `$providerPriority` map actually orders — has **zero production call sites anywhere in `src/`** (grepped the entire tree; only `MetadataManagerTest.php`/`MetadataManagerAnimeIntegrationTest.php` call it). Concretely: `musicbrainz`/ `audiodb` providers are never registered onto the DI-container-resolved `MetadataManager` instance (`MusicLibraryManager::refreshItemMetadata()` calls `$this->metadata->refreshItemMetadata($itemId)`, which is genuinely live/reachable code, but against an empty provider registry, so it is currently a no-op); the legacy `Application::getMusicController()` call site (`Application.php:3390`) constructs `new MetadataManager($itemRepo)` with zero providers registered either. Movie/series/anime matching does NOT go through `MetadataManager::registerProvider()`/`getProvidersForType()` at all — it uses the entirely separate `MovieMetadataResolver`/`SeriesMetadataResolver`/`LibraryMetadataMatcher` + `PriorityConfig`/ `SourceRegistry` path (anidb/myanimelist plugins register into `SourceRegistry` per the Step-3.5 rework documented at `PluginLoader.php:319-321`, explicitly replacing an OLDER pattern where plugins used to sniff for `MetadataManager::registerProvider`). Net effect: fixing S-F48's config divergence is correct and exactly what the finding asked for, but the priority map it fixes currently governs a dormant provider-cascade mechanism with no real registered providers in production — this is a distinct, larger gap (something should call `registerProvider()` for musicbrainz/audiodb, or the whole cascade mechanism should be reconsidered) that deserves its own future finding/step rather than being folded into this S-effort fix. **Verification:** - `./vendor/bin/phpunit --filter MetadataManager` — 30/30 pass. - `./vendor/bin/phpunit --filter MusicLibraryManager` — 11/11 pass. - `./vendor/bin/phpunit tests/Integration/Media/Metadata/MetadataManagerAnimeIntegrationTest.php` — 5/5 pass. - `./vendor/bin/phpunit tests/Unit/Common/Container/ContainerFactoryTest.php` — 22/22 pass (incl. the new `test_metadata_manager_wires_provider_priority_in_prod`). - `./vendor/bin/phpunit --testsuite Integration --filter Metadata` — 7/7 pass. - **Full `./vendor/bin/phpunit --testsuite Unit`: 5133 tests / 39245 assertions / 0 failures / 5 skipped (green at HEAD).** - `./vendor/bin/phpstan analyze src/ -c phpstan.neon.dist` (level 9, whole `src/`): **no errors.** - `./vendor/bin/phpcs --standard=PSR12` on every changed file: `MetadataManager.php` and `config/metadata.php` clean (0 findings); `MediaServicesProvider.php` 4 pre-existing long-line warnings (identical count/nature before and after, confirmed via `git show HEAD~1:… | phpcs` on the pre-diff version — the diff added comment lines that happen to sit near, not on, the existing long lines); `MetadataManagerTest.php` went from 11 errors + 1 warning (pre-existing trailing whitespace + one long-line) down to 0 errors + 1 warning (the diff's whitespace cleanup, a genuine improvement, confirmed by diffing against `git show HEAD~1`); `ContainerFactoryTest.php` went from 21 to 22 snake_case method-name errors (+1, exactly my one new test method, following the file's own pre-existing `test_snake_case_name` convention used by every other method in it — not a new class of violation). **Acceptance criteria (SV-4.10 provider-priority half) — met:** `MetadataManager` no longer hardcodes a provider-priority literal that can silently diverge from `config/metadata.php`; both the ctor-default path (legacy/test construction) and the DI-wired path (production, both entrypoints) resolve to the same config-derived value; an explicit override still works for tests/future callers; the 3rd config subsystem (`PriorityConfig`/`SourceRegistry`) was independently confirmed to be a genuinely separate concern, correctly left unmerged, with the reasoning now verified (not just asserted) in this entry; no contradictory hardcoded priority list remains live anywhere in `src/`. The hrtime half of SV-4.10 was already confirmed done in the 2026-07-12 audit (line ~2575) and re-confirmed untouched by this pass (no `microtime` calls reintroduced; not in this step's file scope). **SV-4.10 is entirely DONE.** ## Reviewer (per-step, SV-4.10, commits `174b283d`+`bc44d308`) — 2026-07-13 Read the step spec (`performance_plan.md` §2 S-W4 SV-4.10 + finding `S-F48` in `performance.md`), this worklog's full SV-4.10 history (2026-07-12 PARTIAL audit at line ~2575 through the Implementer entry above), and both commits via `git show`. Independently re-derived every claim in the Implementer entry rather than trusting it. **Independent verification performed:** - Read the full `174b283d` diff (`MetadataManager.php`, `MediaServicesProvider.php`, `config/metadata.php`, all 3 test files) line-by-line; confirmed the `array_merge($fallback, $configured)` merge direction is correct (config wins for any type it names) and the `@include` path (`__DIR__ . '/../../../config/metadata.php'` from `src/Media/Metadata/`) resolves to the real project-root `config/metadata.php` (3 `../` levels — no wrong-depth landmine like the one that hit SV-3.4 sub-1-3). - **Reproduced the mutation test myself** (independent of the Implementer's own claim): temporarily removed `MediaServicesProvider.php`'s `->constructorParameter('providerPriority', …)` binding, re-ran `ContainerFactoryTest::test_metadata_manager_wires_provider_priority_in_prod` — **it still passed** — then restored the binding (confirmed `git diff` clean afterwards). This independently confirms the claim: the ctor's own `$providerPriority ?? self::defaultProviderPriority()` fallback and the DI factory both call the *exact same* zero-argument static method, so there is no code path where they could diverge (unlike the SV-1.3/1.10/2.9/3.4 landmine class, where the DI-skipped default was a *different*, stale value). The explicit binding is genuinely just documentation-as-code, not load-bearing. Verified accurate, not overclaimed. - Grepped for `registerProvider(` and `getProvidersForType(`/`refreshItemMetadata(` across `src/` to confirm the dormant-code claim independently: `MetadataManager::registerProvider()` has zero call sites outside `MetadataManager.php` itself and the two test files; `Application.php:3390` (`getMusicController()`) and `MusicLibraryManager::refreshItemMetadata()` (the only two production consumers reachable) both construct/ use a `MetadataManager` with nothing ever registered onto it. Confirmed this predates the commit (neither diff touches `registerProvider`/its callers) — the dormancy is pre-existing, not newly introduced or newly worsened by this fix. - Read `PriorityConfig.php`, the `PriorityConfig::class` DI factory and the `MetadataManager::class` DI factory side-by-side in `MediaServicesProvider.php`, plus grepped `MovieMetadataResolver.php`/ `SeriesMetadataResolver.php`/`LibraryMetadataMatcher.php` for `PriorityConfig`/`SourceRegistry`/ `MetadataManager` references, and confirmed `LibraryMetadataMatcher::class` is genuinely wired in both `MediaServicesProvider.php` and `Application.php` (a live path), unlike `MetadataManager::registerProvider()`. The "genuinely separate, correctly left unmerged" verdict holds. - Ran the full verification matrix myself rather than trusting the reported numbers: `--filter MetadataManager` (30/30), `--filter MusicLibraryManager` (11/11), the anime integration test (5/5), `ContainerFactoryTest.php` (22/22), and the **full `--testsuite Unit` suite: 5133 tests / 39245 assertions / 0 failures / 5 skipped** — matches the worklog's reported figures exactly. `phpstan analyze src/ -c phpstan.neon.dist` (L9): no errors. `phpcs --standard=PSR12` on every changed file: `MetadataManager.php` and `config/metadata.php` clean; diffed `MediaServicesProvider.php`/`ContainerFactoryTest.php`/ `MetadataManagerTest.php` against their pre-commit (`174b283d~1`) versions and confirmed the exact reported deltas (4 pre-existing warnings unchanged, 21→22 snake_case errors [+1, the new test], 11 errors+1 warning→0 errors+1 warning). All verification claims in the Implementer entry check out precisely. - Mentally reverted each new/changed test to confirm it would go red pre-fix: `testDefaultProviderPriorityMirrorsConfigMetadataFile`/`testDefaultProviderPriorityTracksArbitraryConfigFileContent`/ `testDefaultProviderPriorityFallsBackWhenConfigFileMissing` all call `MetadataManager::defaultProviderPriority()`, which would not exist pre-fix (fatal error). `testConstructorDefaultPriorityForMovieMatchesConfigNotOldHardcodedLiteral` registers `imdb` for `movie` and asserts it resolves — only true under the new config-derived default (`['tmdb','imdb']`), false under the old hardcoded `['tmdb','local']` (imdb never in that list → empty result → assertion fails). The anime-integration-test edit (registering `tmdb` instead of `tvdb` for `series`) only resolves under the new `['tmdb','imdb']` series default, not the old `['tvdb','fanart','local']` literal. All are genuine regression tests, not decorative. **One finding (LOW severity, non-blocking):** 1. **`config/metadata.php:16-21` (pre-existing) vs `config/metadata.php:27-38` (added by `174b283d`) — the new docblock overclaims consistency with the admin-override path.** `config/metadata.php`'s existing docblock (unchanged by this commit, lines 16-21) states admins may override `metadata.provider_priority` via server settings — a real, live mechanism: `MediaServicesProvider.php`'s `PriorityConfig::class` factory (~lines 189-232) reads `SettingsRepository::getDefault('metadata.provider_priority')` **and** `getOverride('metadata.provider_priority')`, merging any admin override per-type OVER the config default — this is what `MovieMetadataResolver`/`SeriesMetadataResolver`/`LibraryMetadataMatcher` actually consume via `PriorityConfig`. `MetadataManager::defaultProviderPriority()` (`src/Media/Metadata/MetadataManager.php:173-201`), by contrast, reads `config/metadata.php` via a raw `@include` and **never touches `SettingsRepository`** — its `providerPriority` binding in `MediaServicesProvider.php:423-430` calls `MetadataManager::defaultProviderPriority()` directly, bypassing the override entirely. The new docblock text (`config/metadata.php:32-34`) asserts the two subsystems "both now trace back to these SAME values" — true only for the **static file default**; if an admin sets a live `metadata.provider_priority` override via `AdminMetadataSourceController`, `PriorityConfig`-driven resolvers would honor it while `MetadataManager`'s cascade would silently keep using the stale file-only default — reintroducing a config divergence at the override layer instead of the file layer. **This is currently inert in production** (verified above: `MetadataManager::registerProvider()` has zero callers, so its priority map governs nothing reachable today) — so it is not a live bug and does not block SV-4.10, whose declared **Effort: S** scope (per `performance_plan.md` and finding `S-F48`'s literal text, "Load the map from config in `MetadataManager`") says nothing about the admin-override layer. But the new docblock's "same values" framing is not fully accurate, and if the separately-flagged dormant-`registerProvider()` gap is ever closed in a future step, this divergence would become live and worth remembering. Recommend a one-line docblock caveat (e.g. "MetadataManager's default does not consult the live admin override — only PriorityConfig-driven resolvers do") the next time this file is touched, and/or folding a note into the already-flagged future `registerProvider()` follow-up finding. Not required to re-open SV-4.10 for. No other findings. Scope is clean (only SV-4.10-relevant files touched across both commits); no security, async/resident-memory, or Webman-convention issues found; PSR-12/PHPStan-L9 clean; test quality is genuine (every new/changed test verified to go red under a mental revert, and the two most consequential Implementer claims — the DI-binding non-load-bearing claim and the dormant-`registerProvider()` claim — were independently reproduced/reconfirmed rather than taken on faith). **SV-4.10 stands as DONE; the one finding above is an informational follow-up, not a blocker.** ## Implementer — SV-4.10 docblock fix (Reviewer LOW finding) — 2026-07-13 Addressed the single LOW-severity finding from the SV-4.10 per-step Reviewer entry above (`config/metadata.php:16-21` vs `:27-38`, commits `174b283d`+`bc44d308`): the docblock added by `174b283d` claimed `MetadataManager` and `PriorityConfig` "both now trace back to these SAME values", which is only true for the static file default. Re-verified the two facts the finding turns on before editing anything: `MetadataManager::defaultProviderPriority()` (`src/Media/Metadata/MetadataManager.php:173-201`) reads `config/metadata.php` via a raw `@include` and never touches `SettingsRepository`; `PriorityConfig`'s DI factory (`src/Common/Container/Providers/MediaServicesProvider.php:189-232`) reads both `SettingsRepository::getDefault('metadata.provider_priority')` and `getOverride('metadata.provider_priority')` and merges any admin override per-type over the default. So the two subsystems only agree while no admin override is set; `MetadataManager`'s cascade would keep using the stale file-only default if one is. Per the finding, this is inert today (`MetadataManager::registerProvider()` still has zero callers — same dormant-cascade fact re-confirmed by the Reviewer entry above), so this is a doc-accuracy fix only, not a functional change. **Change:** `config/metadata.php` (~lines 39-45) — appended a short caveat paragraph after the existing "both now trace back to these SAME values" text, without rewriting the surrounding docblock: notes the equivalence holds only for the static file default, that `MetadataManager::defaultProviderPriority()` does not consult `SettingsRepository`, and that only `PriorityConfig` (built in `MediaServicesProvider`'s DI factory via `SettingsRepository::getOverride()`) honors a live `metadata.provider_priority` admin override — so the two subsystems diverge the moment an override is set. No code changed; `MetadataManager.php` and `MediaServicesProvider.php` are untouched. **Verification:** `php -l config/metadata.php` clean; `phpcs --standard=PSR12 config/metadata.php` clean; `phpstan analyze src/ -c phpstan.neon.dist` (L9) — no errors; `phpunit --filter MetadataManager` — 30/30 passed, 21071 assertions (unchanged from the SV-4.10 Reviewer's reported baseline — confirms the doc-only edit didn't perturb behavior). Commit: `docs: SV-4.10 fix config/metadata.php docblock — PriorityConfig honors admin overrides, MetadataManager doesn't` (`a8a23bac`). ## Implementer — plugin catalog pin bump to phlix-plugins v2.1.5 — 2026-07-13 Bumped `CatalogSourceResolver::OFFICIAL_PINNED_REF` (`src/Plugins/Catalog/CatalogSourceResolver.php:70`) from `'v2.1.4'` to `'v2.1.5'` — the `phlix-plugins` catalog repo was retagged at commit `2c2bc05` to repin `phlix-plugin-trakt` and `phlix-plugin-musicbrainz` to fixed versions resolving two "unknown event alias" install-blocking bugs. Verified the current value before editing (was genuinely still `v2.1.4`). Grepped `tests/` for `OFFICIAL_PINNED_REF` (10 usages across `PluginCatalogControllerTest`, `PluginAdminControllerTest`, `PluginAutoUpdateWorkerTest`, `PluginUpdateServiceTest`, `PluginCatalogServiceTest` ×3, `CatalogSourceResolverTest`, `PluginInstallCommandTest`) and confirmed every one references the constant symbolically (`CatalogSourceResolver::OFFICIAL_PINNED_REF`), never a hardcoded `'v2.1.4'` literal — also grepped the whole repo (excluding `vendor/`/`node_modules/`) for the literal string `v2.1.4` and found only the one line just changed. So no test fixture needed a companion edit. **Change:** `src/Plugins/Catalog/CatalogSourceResolver.php` — one-line constant bump, no other code touched. Per the task scope, this does NOT deploy to any live box — that remains a separate, explicitly-confirmed step. **Verification:** `php -l` + `phpcs --standard=PSR12` clean on the changed file; `phpstan analyze src/ -c phpstan.neon.dist` (L9) — no errors; `phpunit --filter "CatalogSourceResolver|PluginCatalogController|PluginAdminController|PluginAutoUpdateWorker|PluginUpdateService|PluginCatalogService|PluginInstallCommand"` — 99/99 passed, 310 assertions (all pick up the new pin value automatically via the constant reference). Commit: `plugins: bump OFFICIAL_PINNED_REF to phlix-plugins v2.1.5 (trakt/musicbrainz event-alias fixes)`. ## Implementer — SV-0.9 (batch thumbnail malformed multi-timestamp command) — 2026-07-13 Picked up right where the perf-5 re-audit (line ~2586 above) left off: the escaping half of S-F19 was already fixed (real commit `1f4bfd3d`, "SV-0.9 fix generateThumbnailBatch timestamp escaping + fast seeking" — the hash `1dbdf97c` cited in this session's brief doesn't exist in this repo's history, but `1f4bfd3d` is unambiguously the same fix: it touches exactly `FfmpegRunner.php:878-901`, replaces `escapeshellarg((string)$timestamp)` fed into `%d` with a plain `(int)` cast). That commit's OWN "fast seeking" half is what introduced today's defect, confirmed by reading the diff directly: it moved the per-timestamp `-ss`/`-vframes`/output groups to *before* the single shared `-i`, intending input-side seeking, but bundled the `-vframes`/output-path parts into that same pre-`-i` blob — which is invalid FFmpeg syntax (an output file token appearing before any `-i` has been declared). Confirmed via the audit's description AND by direct code inspection that this is exactly the shape at `src/Media/Transcoding/FfmpegRunner.php` (method `generateThumbnailBatch`, previously lines 1054-1082): `ffmpeg -y -hide_banner -loglevel error -ss T1 -vframes 1 out1 -ss T2 -vframes 1 out2 ... -i input`. **Command-shape decision — Option A (repeated `-ss -i ` blocks), not Option B:** the plan's own SV-0.9 "Do" text is explicit ("move `-ss` to input-side (before `-i`) for fast seeking") and S-F19's stated Acceptance Criterion is "encode is fast (input-side seek)" — that rules out reverting to the pre-`1f4bfd3d` shape (single shared `-i`, per-output *output-side* `-ss` — valid FFmpeg syntax but the "slow" seek mode the finding explicitly flags). So the fix gives **each timestamp its own `-ss -i ` pair** (same file re-opened N times, but all N `-i` occurrences + N outputs still run inside **one** FFmpeg process/one `exec()` call — FFmpeg natively supports repeated `-i` with distinct per-input options), with all inputs declared before any output group, and **each output explicitly pinned to its own input via `-map :v:0`**. The `-map` is not optional here: without it, FFmpeg's default per-output stream auto-selection is free to bind any already-open input to a given output, and since every input in this command is literally the *same file* re-opened at a different `-ss` offset, an unmapped output could silently receive the wrong (or a duplicate) timestamp's frame — empirically confirmed this matters by testing the interspersed-input/output form (`-i in -vframes 1 out1 -ss T -i in -vframes 1 out2`, no `-map`) against a real multi-input FFmpeg invocation before settling on the always-`-map`'d shape below. **Refactor:** extracted the command construction into a new public `buildThumbnailBatchCommand(string $inputPath, array $timestamps, string $outputDir): string`, matching this file's established `buildCmafCommand()` / `buildSegmentCommand()` / `buildHwaccelSegmentCommand()` / `buildDetachedCommand()` builder convention (a pure string-returning method makes the shape directly unit-testable without invoking a real FFmpeg binary). `generateThumbnailBatch()` now just calls the builder then executes via the existing `runCoroutineAwareCommand()`. **Extra correctness hardening found while empirically verifying the fix (see box below):** tested the new command against a real `/usr/bin/ffmpeg` (available in this sandbox) with one and then *all* requested timestamps beyond the clip's duration. In both cases FFmpeg **exits 0** — an out-of-range `-map N:v:0 -vframes 1 ` just logs a non-fatal "Output file is empty, nothing was encoded" and skips that particular output, it does not fail the whole process. That means the pre-existing `return $exitCode === 0` contract silently reports "success" even when **zero** thumbnails were written — a different manifestation of the same underlying "batch call silently produces nothing" bug class this step is about. Hardened `generateThumbnailBatch()` to also verify at least one of the expected `frame_NNNNN.jpg` files actually exists and is non-empty before returning `true`; returns `false` if the process failed outright (exit ≠ 0) *or* if not a single requested frame materialized. Partial success (some timestamps in range, some not) still returns `true`, preserving the intended best-effort batch semantics. **Files changed:** - `src/Media/Transcoding/FfmpegRunner.php` — added `buildThumbnailBatchCommand()`; rewrote `generateThumbnailBatch()` to call it + do the existence-check hardening described above; updated both methods' docblocks with `@since SV-0.9` notes describing the defect and fix. - `tests/Unit/Media/Transcoding/FfmpegRunnerThumbnailBatchTest.php` (**new**) — pure string-shape assertions on `buildThumbnailBatchCommand()`: each timestamp pairs with its own `-ss -i ` and its own `-map :v:0 -vframes 1 `; no `escapeshellarg()` wrapping the numeric (`-ss 30` not `-ss '30'`); every `-i` occurs before the first `-map` (the direct regression guard for the exact malformed-shape defect); exact input/output counts for N timestamps; distinct non-zero timestamps preserved (not coerced to 0); non-sequential/associative input keys (`[7 => 20, 3 => 40]`) still re-index outputs to a clean `frame_00000`/`frame_00001` run; empty-array short-circuit still returns `true`. - `tests/Integration/Media/Transcoding/FfmpegThumbnailBatchTest.php` (**new**, self-skips if `ffmpeg` isn't installed, matching the existing `FfmpegHlsTranscodeTest` pattern) — generates a real 5-second synthetic clip via `lavfi testsrc` and drives `generateThumbnailBatch()` against the real binary: (1) two in-range timestamps produce two non-empty, **byte-distinct** frames (the direct regression guard for "all frames at t=0"/"no thumbnails rendered at all"); (2) one in-range + one out-of-range timestamp still returns `true` with only the in-range frame written (partial-success tolerance); (3) *all* timestamps out-of-range returns `false` even though FFmpeg itself exits 0 (the existence-check hardening's own regression guard). This method had **zero** test coverage before this change, per the audit. **Wiring a real caller — evaluated, deliberately left uncalled (documented per plan §0.1's "if not, it's fine to leave it correctly-implemented-but-uncalled" escape hatch):** grepped every caller of `generateThumbnail`/`generateThumbnailBatch` in `src/`. The only production caller remains `MediaAssetGenerationJob::generateChapterThumbnails()` (`src/Media/MediaAsset/ MediaAssetGenerationJob.php:93-149`), which loops over a video's chapters calling the *scalar* `generateThumbnail($path, $thumbPath, $startSeconds)` once per chapter — the one plausible "N separate single-timestamp calls that could become one batch call" candidate the task asked me to look for. Deliberately did **not** wire it this session, for three concrete reasons found during the evaluation: 1. **No safety net.** `MediaAssetGenerationJob` has **zero** existing tests (confirmed via `find tests -iname '*MediaAssetGenerationJob*'` → no results) — switching its chapter-thumbnail path to the batch call would be an untested behavioral change to a live production job with no regression coverage of its own, which is a materially bigger lift than "wire a call" (it would need its own dedicated test suite built out first, not just a call-site edit). 2. **Modest actual win.** Movie/episode chapters are typically spread across the *whole* runtime (not clustered like trickplay's evenly-spaced grid, which already has its own efficient single-decode-pass sprite-sheet method, `generateTrickplaySprites()` — confirmed by reading it, this is NOT a candidate, it was never doing N separate calls). Because the Option A shape still re-opens+re-seeks the same file once per chapter (just inside one process instead of N), the real saving from switching would be N-1 fewer process spawns, not less decode work — a legitimate but modest gain, not the clear multi-x win batch extraction gives for tightly-clustered timestamps. 3. **Semantics changed enough to need its own review.** The current per-chapter loop tolerates one bad chapter without losing the others via a per-call `try`/`$anySuccess` flag. Wiring the batch call safely would additionally require the caller to check each `frame_NNNNN.jpg`'s existence itself (the aggregate `bool` doesn't tell you *which* timestamp(s) succeeded) — doable, but a distinct, scoped change deserving its own test-covered step rather than being folded silently into this command-shape fix. Recording this as an honest candidate for a future, separately-scoped step (something like "SV-0.9-followup: batch chapter-thumbnail extraction + build MediaAssetGenerationJob test coverage") rather than forcing it in here. **Verification:** - New Unit test: `phpunit --filter FfmpegRunnerThumbnailBatchTest` → **5/5 passed, 22 assertions** (corrected 2026-07-13 Fix pass; originally miscited here as 6/6, 23 — the file has exactly 5 test methods). - New Integration test (real `/usr/bin/ffmpeg` 6.1.1, present in this sandbox): `phpunit --filter FfmpegThumbnailBatchTest --no-coverage` → **3/3 passed, 19 assertions** (empirically confirmed: two in-range timestamps → two distinct non-empty frames; one in-range + one OOB → `true` + only the in-range frame written; all-OOB → `false` even though the underlying FFmpeg process itself exits 0). - `phpunit --filter FfmpegRunner --no-coverage` (broader regression net on the whole class) → **60/60 passed, 254 assertions** (corrected 2026-07-13 Fix pass; originally miscited here as 61/61, 255 — consistently reproduces as 60/60 across reruns). - `phpstan analyze -c phpstan.neon.dist` on `FfmpegRunner.php` + both new test files → **0 errors**. - `phpcs --standard=PSR12` on all three changed/new files → **0 errors**, 1 pre-existing 129-char warning at line 956 (`buildDetachedCommand`'s signature — outside this diff's line range, confirmed via `git diff` hunks all starting at line 1040+; unrelated pre-existing warning, not introduced by this change). - `phpunit --testsuite Unit --no-coverage` (full suite) → **5138 tests, 39267 assertions, 0 failures, 5 skipped** (pre-existing skips). **Acceptance criteria met:** batch thumbnails now render at the requested (distinct) timestamps rather than none at all — proven against a real FFmpeg binary, not just string-matched; encode uses input-side (fast) seeking per timestamp via the repeated `-ss -i ` shape; a dedicated command-shape test (+ real-FFmpeg integration test) now covers a method that previously had zero coverage. **Commit:** `d3062086` — `transcode: SV-0.9 fix generateThumbnailBatch malformed multi-timestamp command`. Pulled (`git pull --rebase origin master` — already up to date, no conflicts) and pushed directly to `master` per §F. ### Fix pass — SV-0.9 review findings (2026-07-13, commit `20dc2370`) Three review findings from the SV-0.9 review, all docblock/comment/worklog-only (no behavioral change — the `d3062086` code fix itself is sound and unchanged): 1. **[Medium] Overclaimed "rendered no thumbnails at all" defect narrative.** Verified against this box's real ffmpeg 6.1.1: reverting to the pre-fix shape (`ffmpeg ... -ss T1 -vframes 1 out0 -ss T2 -vframes 1 out1 -i input`, outputs bunched before the single shared `-i`) actually produced **correct, distinct, non-empty frames** — byte-for-byte identical md5s to the fixed shape's output. So the pre-fix shape did NOT render zero thumbnails; ffmpeg tolerated the input-after-outputs ordering (an arrangement not guaranteed by its documented option ordering) and used a slow output-side seek. Corrected the narrative in: the Integration test class docblock + inline comment/assertion message (softened to describe a positive end-to-end correctness check, explicitly noting it is NOT a shape regression guard — only the Unit string-shape tests genuinely guard the shape change); the Unit test class docblock + inline comment (kept the real shape-guard framing, dropped the false "renders no thumbnails" consequence); and `generateThumbnailBatch()`'s `@since SV-0.9` docblock note in `FfmpegRunner.php`. NOTE: the earlier `d3062086` commit message's "rendered no thumbnails at all" phrasing was an **overclaim** — the *fix is still correct* (fast input-side seek + explicit `-map`, no reliance on ffmpeg's lenient arg reordering), but the *narrative* about why it was needed was wrong. That commit message is already on master and is **not** rewritten/force-pushed (§F); only the code/test docblocks + this worklog are corrected. 2. **[Low] `@return bool` didn't state partial-success inline.** Tightened `generateThumbnailBatch()`'s `@return bool` line itself to state partial-success semantics (true if ≥1 requested timestamp produced a non-empty frame, so a mix of in-range/out-of-range still returns true; false only on ffmpeg exit != 0 or zero frames written) rather than leaving it implied only by the `@since` note. 3. **[Informational] Worklog test count.** Corrected `phpunit --filter FfmpegRunner` count from the miscited **61/61 → actual 60/60** (254 assertions), and the Unit-file count from **6/6 → actual 5/5** (22 assertions); both reproduce consistently. **Files changed:** `src/Media/Transcoding/FfmpegRunner.php` (generateThumbnailBatch docblock — `@return` + `@since SV-0.9` note); `tests/Integration/Media/Transcoding/FfmpegThumbnailBatchTest.php` (class docblock + distinct-frames comment/message); `tests/Unit/Media/Transcoding/FfmpegRunnerThumbnailBatchTest.php` (class docblock + inputs-before-outputs comment); this worklog. **Verification (docblock/comment-only, suite stays green):** - `phpunit --filter FfmpegRunner --no-coverage` → **60/60 passed, 254 assertions**. - `phpunit --filter 'FfmpegRunnerThumbnailBatchTest|FfmpegThumbnailBatchTest' --no-coverage` → **8/8 passed, 41 assertions** (5 Unit + 3 Integration). - `phpstan analyse -c phpstan.neon.dist` on `FfmpegRunner.php` + both test files → **0 errors** (L9). - `phpcs --standard=PSR12` on all three files → **0 errors**; only the pre-existing 129-char warning at `FfmpegRunner.php:956` (`buildDetachedCommand`, outside this diff) remains. **Result:** SV-0.9 review findings 1–3 resolved. Commit `20dc2370` — `thumbnails: SV-0.9 fix: correct overclaimed defect narrative + @return docblock`, pushed to master. ## Implementer — SV-4.4 (webhook connect-timeout + jittered one-shot backoff retry) — 2026-07-13 **Audit (per this pass's "don't trust a prior claim, verify against current code" discipline):** the checklist line at the top of this file cited commit `410ffce0` as the fix — that commit **does not exist** in this repo's history (`git show 410ffce0` → "unknown revision"), the same stale-audit-trail rot already documented for SV-4.10/SV-0.8 earlier this pass. The one trustworthy prior note was the 2026-07-12 re-audit roll-up (this file, "SV-4.1–4.6 RE-AUDIT" section): "PARTIAL (inert)". Re-verified against the actual current code rather than taking either claim on faith: 1. **Two entirely separate, both-live webhook subsystems exist** (confirmed by grepping every caller of both): - `WebhookDispatcher` (table `webhooks`/`webhook_logs`) is CRUD-only in practice: its `dispatch()` method has exactly ONE caller anywhere in `src/` — `WebhookAdminController::test()`, the admin "send a test event to this webhook now" button (`POST /api/v1/admin/webhooks/{id}/test`). `dispatchAsync()`/`sendToWebhookWithBackoff()`/`computeBackoffDelayMs()` (added by an earlier partial pass, with the CORRECT jittered-backoff-via-one-shot-Timer shape) have **zero callers anywhere** — genuinely dead code, confirmed via `grep -rn "dispatchAsync\b" src/ tests/` → only the definition line matches. - `WebhookService` (tables `webhook_subscriptions`/`webhook_events`/`webhook_deliveries`) is the REAL production path: `WebhookEventSubscriber` (wired in `EventServicesProvider`, the only class bound to the PSR-14 event dispatcher for webhooks) calls `WebhookService::emit()` for every real domain event (`media.added`, `playback.started`, `user.login`, etc.) → `queueDeliveries()` → a one-shot `Timer::add(0, …, [], false)` → `processDelivery()` → `handleFailedDelivery()` on failure, which already had DB-persisted retry state + a genuinely one-shot Timer, but its base delay (30s/300s/1800s from `WebhookDeliveryRecord::RETRY_DELAYS`) had **zero jitter** — a real thundering-herd risk (e.g. many deliveries queued around a worker restart, or many subscriptions pointing at the same now-down endpoint, would all retry at the exact same instant). - `S-F10`'s finding location (`WebhookDispatcher.php:261-309`, blocking curl + immediate 3× retry + no connect-timeout) maps onto the CURRENT `sendToWebhook()` (the method backing the one live caller, `dispatch()`/admin-test) — it still had the exact defect described: a fresh, duplicated raw `curl_init()`/`curl_setopt()` block (not delegating through `WebhookHttpClient` at all), `CURLOPT_TIMEOUT` only (no `CURLOPT_CONNECTTIMEOUT`), and a `do..while` retry loop that `continue`s immediately on failure with **zero delay**. - `WebhookHttpClient` (shared by both subsystems) had **no connect-timeout anywhere** — neither `CURLOPT_CONNECTTIMEOUT` in its blocking-cURL fallback nor a `'connect_timeout'` option on its `Workerman\Http\Client` construction (confirmed `workerman/http-client`'s `ConnectionPool` genuinely tracks `connect_timeout` as a knob distinct from `timeout` — read `vendor/workerman/http-client/src/ConnectionPool.php:44-50,164-196` — so this is a real, not cargo-culted, fix, matching the exact pattern already used by `ArtworkStorage` (SV-3.4), the only other class in this codebase that already sets both). **Fix (`7f434d03`):** 1. **`src/Webhooks/WebhookHttpClient.php`** — added `DEFAULT_CONNECT_TIMEOUT=5` + a `$connectTimeout` ctor param (threaded to both the async `Client(['timeout'=>…, 'connect_timeout'=>…])` and `curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, …)` on the blocking fallback), plus a `getConnectTimeout()` getter (for tests). Refactored `post()` to delegate through a new public `postWithHeaders(string $url, array $headers, string $body)` — generalizes the already-generic private `postAsync`/`postCurl` methods to accept caller-supplied headers/body instead of only `post()`'s hardcoded `X-Phlix-Event`/`X-Phlix-Delivery` + `{payload,signature}` JSON envelope, so `WebhookDispatcher::sendToWebhook()` (below) can reuse the same connect-timeout-aware, coroutine/blocking-context-aware dispatch **without changing its wire format** (still `X-Phlix-Signature` header + raw event JSON body — a real webhook receiver sees no difference). 2. **`config/webhooks.php`** — added a documented `'connect_timeout' => 5` key (mirrors the existing `'timeout'`/`'max_retries'` config-driven pattern). 3. **`src/Webhooks/WebhookDispatcher.php`**: - `getHttpClient()` now reads `connect_timeout` from config too (used by the dead `dispatchAsync` path, left in place — see below). - `sendToWebhook()` (the live method) rewritten to call `$this->getHttpClient()->postWithHeaders($url, $headers, $payload)` instead of a fresh `curl_init()` block, and to sleep a jittered backoff delay (`computeBackoffDelayMs()`, already present but previously only used by the dead code path — now doing real work) between synchronous retry attempts via a new `protected function sleepMilliseconds(int $ms): void` (`usleep()`, cooperatively yields under the Swoole coroutine SLEEP hook — the exact same idiom already established in `MetadataHttpClient::get()`'s retry loop; protected so tests can spy/ no-op it). Retry count/attempt semantics (`max_retries`, default 2 ⇒ 3 total attempts) unchanged — only the zero-delay behavior between attempts was fixed. 4. **`src/Webhooks/WebhookDeliveryRecord.php`** — added `RETRY_JITTER_FRACTION=0.2` and a new `calculateNextRetryDelaySeconds(): ?int` (base delay from the existing fixed `RETRY_DELAYS` schedule ± a uniform random 20% window via `mt_rand`, `null` once `attempt >= MAX_ATTEMPTS` — the retry cap). `calculateNextRetryAt()` gained an optional `$delaySecondsOverride` param so a caller can compute the jittered delay **once** and thread the identical value into both the persisted timestamp and a Timer delay — calling either method twice independently would draw two different random jitters and let the DB `next_retry_at` drift from the actual retry. 5. **`src/Webhooks/WebhookService.php`** — `handleFailedDelivery()` now computes `$delaySeconds = $delivery->calculateNextRetryDelaySeconds()` once, derives `$nextRetryAt` from that same value via the override param, and schedules `Timer::add((float) $delaySeconds, …, [], false)` from that same value — the DB row and the actual retry can never disagree. Removed the now-redundant private `calculateDelaySeconds()` (duplicated the same `RETRY_DELAYS` lookup with no jitter; superseded by the DTO method). The one-shot `Timer::add(…, [], false)` shape itself was already correct and is unchanged — only the delay computation changed. **Dead `dispatchAsync` — left in place, not wired, not deleted (per §0.1/§6):** wiring it in would mean adding a SECOND, competing, less-durable delivery mechanism (in-memory attempt counter that doesn't survive a worker restart) alongside the already-live, DB-persisted `WebhookService` path — that would be new architecture invention, not a fix for S-F10. Deleting it is also not this session's call per §0.1 (no deletion without user sign-off). Recording it here as a genuine **candidate for the global §6 removal-confirmation queue** in `performance_plan.md` (not edited by this step, since that file is the orchestrator's shared cross-repo document): `WebhookDispatcher:: dispatchAsync()` / `sendToWebhookWithBackoff()` / (now, incidentally, no longer `computeBackoffDelayMs()` — that helper is now genuinely used by `sendToWebhook()`) are zero-caller and duplicate functionality `WebhookService` already provides more robustly. A future pass should ask the user whether to remove `dispatchAsync`/`sendToWebhookWithBackoff` specifically (keeping `computeBackoffDelayMs()`, which is now live). **Tests added (all new files — `WebhookHttpClientTest`/`WebhookDeliveryRecordTest`/ `WebhookServiceTest` did not exist before this change; `WebhookService` had ZERO test coverage of any kind prior to this step):** - `tests/Unit/Webhooks/WebhookHttpClientTest.php` — connect-timeout getter defaults/configurable; a reflection-based test that the async client's real underlying `Workerman\Http\ConnectionPool` (not just this class's own field) is constructed with the configured `connect_timeout` **distinct** from `timeout` (reads `Client::$_connectionPool`→`ConnectionPool::$options` directly — proves the wiring reaches the actual vendor knob, not just an echoed getter); async client is lazily cached (not rebuilt per request); `post()` still produces its documented wire format after being refactored to delegate through `postWithHeaders()` (regression guard for the refactor); empty-URL short-circuit on both `post()`/`postWithHeaders()` (kept fast/offline — no real network needed). **Curl-option verification boundary, documented rather than faked:** consistent with this codebase's existing convention (`ArtworkStorageTest`/`PluginCatalogServiceTest` don't unit-test literal `curl_setopt()` values either — there's no interception seam for a static-function C extension call), this suite does not assert `CURLOPT_CONNECTTIMEOUT`'s literal value on the blocking path; it is wired from the exact same `$this->connectTimeout` property proven-correct on the async side, and is `phpstan`-typed (`int`) end-to-end. - `tests/Unit/Webhooks/WebhookDeliveryRecordTest.php` — jittered delay stays within the documented ±20% window for attempts 0/1/2 (30s/300s/1800s bases ⇒ [24,36]/[240,360]/[1440,2160], which **never overlap**, so "grows across retries" holds regardless of the random draw — asserted over 50 iterations, not a single flaky sample); jitter genuinely varies across calls (not collapsed to a constant — asserted `count(array_unique(...)) > 1` over 30 draws); `null` at and beyond `MAX_ATTEMPTS` (the cap); `calculateNextRetryAt()` uses a provided override delay exactly (proves the drift-prevention contract) and returns `null` when the override is `null`. - `tests/Unit/Webhooks/WebhookServiceTest.php` — the most important file for this step's stated priority ("the single most important regression guard here"): **genuinely-one-shot is proven against Workerman's own internal bookkeeping, not source inspection.** `Timer::add()`'s real implementation (`vendor/workerman/workerman/src/Timer.php`) stores `self::$tasks[$runTime][$timerId] = [$func, $args, $persistent, $timeInterval]` and increments a protected static `$timerId` counter by exactly 1 per call (confirmed by reading the vendor source first) — mirrors the `StreamSessionServiceTest`/SV-0.5 idiom of constructing a bare `if (!Worker::getAllWorkers()) { new Worker(); }` so `Timer::add()` doesn't throw, but goes one step further than that existing pattern (which only asserts bookkeeping counts) by reflecting into `Timer::$timerId`/`Timer::$tasks` to read back the **literal `persistent` flag Workerman stored** for the exact timer id the call under test just registered, and asserting it's `false`. A source-level regression that flipped the 4th `Timer::add()` arg from `false` to `true` (or dropped it, defaulting to the persistent/repeating form — exactly SV-0.5's WS-reaper timer-storm bug class) would be caught by this test, not just by re-reading the diff. Covers: a failed delivery with retries remaining registers exactly one new one-shot timer AND the persisted `next_retry_at` timestamp falls within the same jittered window used for that timer (proves the single-source-of-truth fix — this is the exact drift bug the refactor closes); max-attempts reached marks the delivery permanently `'failed'` and registers **no** new timer (the retry cap); two consecutive failures each register their OWN distinct one-shot timer (guards against accidentally reusing one repeating timer for a whole retry sequence). Each test explicitly `Timer::del()`s any timer it registers so nothing leaks into other tests sharing the process. **Verification:** - `phpunit --filter Webhook --testdox` → **82/82 passed, 1088 assertions** (includes the 3 pre-existing Webhook* suites — `WebhookDispatcherTest`, `WebhookEventTest`, `WebhookAdminControllerTest`, `TlsVerificationTest`, the plugin suites — none regressed). - `phpstan analyze -c phpstan.neon.dist` on all 5 changed/new source files + 3 new test files → **0 errors**. - `phpcs --standard=PSR12` on the same 8 files → **0 errors**; 1 pre-existing 125-char warning at `WebhookDeliveryRecord.php:126` (the `fromRow()` `responseCode:` line) — confirmed via `git diff --unified=0` that this line is untouched by this change, left as-is (out of scope). - Full `phpunit --testsuite Unit` → **5152 tests, 40148 assertions, 0 failures, 8 skipped** (pre-existing skips — no reachable MySQL/real-network fixtures in this sandbox, unrelated to this change). **Acceptance criteria met:** (1) live delivery path identified correctly (`WebhookService`, not the dead `WebhookDispatcher::dispatchAsync`) before making any change, per the task's explicit don't-assume-from-the-name instruction. (2) Connect-timeout added and config-driven on both the blocking-cURL and async-client code paths, distinct from the total request timeout. (3) Jittered exponential/percentage backoff added to the LIVE retry path (`WebhookDeliveryRecord`/ `WebhookService`) and to the previously-zero-delay synchronous admin-test path (`WebhookDispatcher::sendToWebhook`), both capped (MAX_ATTEMPTS=3 / `max_retries` config). (4) The one-shot `Timer::add(…, [], false)` shape was already correct on the live path and is now backed by a test that inspects Workerman's real bookkeeping rather than trusting the source. (5) Dispatch confirmed to already use the async-client pattern (Channel-based cooperative wait in a coroutine, blocking cURL fallback otherwise) consistent with the other 4 clients from SV-0.3/0.4 — the `sendToWebhook` admin-test path now also goes through that same pattern instead of a fresh raw `curl_init()` call. **Commit:** `7f434d03` — `webhooks: SV-4.4 add connect-timeout + jittered one-shot backoff retry`. Pulled (`git pull --rebase origin master` — already up to date, no conflicts) and pushed directly to `master` per §F. ## Reviewer (per-step) — 2026-07-13 Scope: SV-4.4 code commit `7f434d03` (+ docs `ee0659a6`; HEAD `ee0659a6`). Verified against S-F10, the plan step, and the actual diff — not the handoff summary. **Production code: correct and complete.** All reachable delivery paths carry a connect-timeout, jitter bounds are sane, timers are genuinely one-shot, and no path retains the old zero-delay/no-connect-timeout behavior: - Connect-timeout on EVERY reachable path — `WebhookHttpClient` sets both `CURLOPT_CONNECTTIMEOUT` (blocking, :248) and `'connect_timeout'` (async, :285); the async knob is genuinely honored by `vendor/workerman/http-client/src/ConnectionPool.php:164-175` (not a no-op key). Both live subsystems route through it: `WebhookService::processDelivery`/retry (`:209,:376` → `httpClient->post`) and `WebhookDispatcher::sendToWebhook` (`:388` → `postWithHeaders`). The autowired `WebhookHttpClient` (AdminServicesProvider:183) gets `DEFAULT_CONNECT_TIMEOUT=5` — config-driven only on the Dispatcher path, default-driven on the Service path, but present on both. - Jitter bounds sane — `WebhookDeliveryRecord::calculateNextRetryDelaySeconds()` uses `max(1, base+jitter)` with `mt_rand(-window,window)`, window=±20%; ranges [24,36]/[240,360]/ [1440,2160] never negative, never zero, non-overlapping. `computeBackoffDelayMs()` returns [delay, 2*delay], never negative. `mt_rand` is pure/non-blocking — fine under the coroutine runtime. - One-shot timers — `WebhookService::handleFailedDelivery` schedules `Timer::add((float)$d, …, [], false)`; proven one-shot by reading Workerman's own `Timer::$tasks[...][2]` persistent flag. - Single-source-of-truth — `$delaySeconds` computed once, threaded to both `next_retry_at` (via the new `$delaySecondsOverride`) and the Timer; the dead `calculateDelaySeconds()` removed with no stale references. - No blocking curl on the event-loop path — `postWithHeaders` gates the async branch on `WorkerContext::isEventLoopRunning() && inCoroutine() && !EventLoopTls::requiresBlockingCurl()`. ### Findings (2, both Low — test-rigor / mutation-testing gaps; no production defect) 1. **Low — `tests/Unit/Webhooks/WebhookServiceTest.php:153-171`** (the drift / single-source-of-truth guard). The assertion only checks the persisted `next_retry_at` delta falls within the jittered window `[239,361]`; it never reads the timer's actual scheduled interval (`Timer::$tasks[$runTime][$timerId][3]`, confirmed to hold `$timeInterval`) and compares it to `$deltaSeconds`. Reverting the fix so `next_retry_at` and the Timer each draw an INDEPENDENT jitter (the exact drift bug this refactor closes) leaves both values inside `[240,360]` → the test stays GREEN. So the single-source-of-truth property the worklog claims this test "proves" is not actually guarded. Why it matters: a future edit could silently reintroduce DB/Timer drift with no red test. Fix: also read `[$timerId][3]` and assert it equals the `next_retry_at` delta (derive both from one draw). 2. **Low — `tests/Unit/Webhooks/WebhookHttpClientTest.php:97-110`** (`testPostDelegatesToPostWithHeadersPreservingWireFormat`). Docblock claims a "pure regression guard that the SV-4.4 refactor didn't change post()'s public contract [wire format]," but the body only exercises the empty-URL short-circuit and asserts `error === 'Empty URL'` — functionally identical to `testPostWithHeadersShortCircuitsOnEmptyUrlWithoutNetwork` (:112). It never inspects the `X-Phlix-Event`/`X-Phlix-Delivery` headers or the `{payload,signature}`/JSON envelope that `post()` builds. A regression in that envelope — which `WebhookService`'s LIVE delivery path (`:209,:376`) depends on — would leave this test GREEN. Wire format is asserted nowhere. Fix: capture the headers/body actually built (e.g. spy `postWithHeaders`, or a seam over `postCurl`) and assert the envelope, or drop the misleading "wire format" claim. Note (not a finding, per task): the intentionally-retained dead `WebhookDispatcher::dispatchAsync()`/`sendToWebhookWithBackoff()` is a tracked §6 removal candidate, not a defect. The blocking-cURL `CURLOPT_CONNECTTIMEOUT` literal value is unasserted by documented codebase convention (no interception seam for the static C-extension call) — acceptable; the async side is fully proven. **Verdict: 2 findings (both Low, test-rigor only). Acceptance criteria and code are otherwise met.** ## Fixer (test-rigor) — SV-4.4 review findings — 2026-07-13 Both Low findings above were "decorative" tests (stayed GREEN when the SV-4.4 production fix was reverted). Both are now genuine mutation-guarding tests. No production code changed — test files only. **Commit `69135f02`** — `SV-4.4 tests: guard next_retry_at↔timer single-source + real post() wire-format`. - **Finding 1 (`WebhookServiceTest.php`)** — replaced the window-only assertion (which only checked `next_retry_at`'s delta fell within `[239,361]`) with a direct single-source-of-truth guard: a new `scheduledIntervalFor()` helper reads the interval Workerman actually registered the timer with (`Timer::$tasks[$runTime][$timerId][3]`, verified against `vendor/workerman/workerman/src/Timer.php:171` = `[$func, $args, $persistent, $timeInterval]`), and the test now asserts the delay implied by the persisted `next_retry_at` **equals** that scheduled interval (`assertEqualsWithDelta(..., 0.5)`), i.e. both derive from the ONE computed `$delaySeconds`. Seeded (`mt_srand(20260713)`) so the invariant is deterministic (first two jitter draws = +5s / −13s). It also now bounds the *scheduled interval itself* (not just `next_retry_at`) to the ±20% window `[240,360]`. - **Finding 2 (`WebhookHttpClientTest.php`)** — `testPostDelegatesToPostWithHeadersPreservingWireFormat` no longer duplicates the empty-URL short-circuit (the `:112` test). It now drives `post()` through a partial mock (`onlyMethods(['postWithHeaders'])`) and asserts `post()` delegates through `postWithHeaders()` exactly once, with the precise wire format — URL verbatim, the `Content-Type`/`X-Phlix-Event`/`X-Phlix-Delivery` header envelope, and the JSON-encoded body — and returns `postWithHeaders()`'s result verbatim. **Mutation-revert confirmation (both flip RED when the specific SV-4.4 hunk is reverted; reverts run uncommitted in the working tree, then `git checkout` restored the pristine source — never committed):** - Finding 1: reverted `WebhookService::handleFailedDelivery` to two independent jitter draws (`$nextRetryAt = calculateNextRetryAt(); $delaySeconds = calculateNextRetryDelaySeconds();`) → `testFailedDeliveryWithRetriesRemainingSchedulesAGenuineOneShotTimer` **FAILED**: "Failed asserting that 305.0000159740448 matches expected 287.0" (next_retry_at from draw +5 = 305s vs Timer from draw −13 = 287s — the drift the fix prevents). - Finding 2: reverted `post()` to bypass `postWithHeaders()` (call `postCurl()` directly) → `testPostDelegatesToPostWithHeadersPreservingWireFormat` **FAILED**: the real cURL result (example.com → 405) replaced the stubbed envelope, so `assertSame` mismatched. Restored to the delegating form. **Verification (actual output):** webhook Unit subset `phpunit --filter Webhook` **82/82 pass (1090 assertions)** (was 1088 pre-fix — 2 net new assertions); `tests/Unit/Webhooks/` dir 69/69. `phpstan analyse -c phpstan.neon.dist --memory-limit=512M` → **0 errors**. `phpcs --standard=PSR12 ` → **0 errors** (exit 0). No production/source files touched — the two Low findings closed. **SV-4.4 test-rigor findings CLOSED.** ## Implementer — SV-3.1 f-a (DB-backed timeshift session store + migration) — 2026-07-13 First sub-step of SV-3.1 **f** (timeshift data plane). Builds the persistence layer ONLY — the ffmpeg rolling-buffer writer (f-b) and the `LiveTvStreamController` 501-stub replacement (f-c) consume this next and are out of scope here. No wiring into `Recorder` / the DI provider yet (deliberate — DI binding lands in f-b with a real consumer, to avoid the untested PHP-DI-skips-nullable-ctor-param landmine). **Architectural gap closed (foundation for):** timeshift state lived only in `Recorder::$activeTimeShifts` — a per-worker in-memory array — so a session started on worker N was invisible to a `/livetv/timeshift/{session}/stream` request routed to worker M (404). This gives every worker a shared, authoritative view (mirrors the project's `Db*StateStore` pattern). **Files added (commit `4f7d2c89`, pushed to master):** - `migrations/078_livetv_timeshift_sessions.sql` — new table `livetv_timeshift_sessions`. Modelled VERBATIM on `livetv_recordings` (012a) conventions: `id CHAR(36)` PK, epoch `INT UNSIGNED` time (`buffer_start_at`/`buffer_end_at`, matching Recorder.php's time()-based `buffer_start`/`buffer_end`), `buffer_dir VARCHAR(512)`, nullable `pid INT`, `window_seconds` (default 7200 = `Recorder::TIMESHIFT_BUFFER_SECONDS`), `cursor_position` (int, default 0), `status VARCHAR(32)` default `'active'`, DATETIME `created_at`/`updated_at` with `ON UPDATE`, `ENGINE=InnoDB … utf8mb4_unicode_ci`. Idempotent `CREATE TABLE IF NOT EXISTS` (valid on MySQL 8 + MariaDB; no `IF NOT EXISTS` column/index clauses). No expected-migration-files list exists in the repo (MigrationRunner globs the dir), so nothing to update there. - `src/LiveTv/TimeShift/TimeShiftSession.php` — immutable value object, modelled on `Media\Library\BookProgress` (readonly promoted props + `toArray()`), plus `start()` (fresh-session factory, cf. `BookProgress::fresh`) and `fromRow()` (RowMap-narrowing hydration). Carries `session_id` in addition to the prompt's column list — it matches the existing `$activeTimeShifts` sibling shape AND is the `/livetv/timeshift/{sessionId}/stream` URL key the documented core bug turns on (see divergence note below). - `src/LiveTv/TimeShift/DbTimeShiftSessionStore.php` — CRUD-only store modelled on `Media\Library\BookProgressStore` + `Auth\DbLoginRateLimitStore`: single injected `Workerman\MySQL\Connection`, **positional `?` binds** (the sibling idiom; the project's connection subclass re-keys them), no business logic. Methods: `save()` (INSERT … ON DUPLICATE KEY UPDATE upsert, `updated_at` via the column default), `findById()`, `findBySessionId()` (newest-first), `updateCursor()`, `updateBufferWindow()`, `updatePid()`, `updateStatus()`, `delete()`, `listActive()`. - `tests/Unit/LiveTv/TimeShift/DbTimeShiftSessionStoreTest.php` — 16 tests modelled on `BookProgressStoreTest` (mock `Connection`): create; save-upsert positional-param shape; findById round-trip; findById→null on empty AND on `false`; findBySessionId ORDER/LIMIT; updateCursor/BufferWindow/Pid(int)/Pid(null)/Status/delete param shapes; listActive hydrates + binds `STATUS_ACTIVE`, and →[] on `false`; start() factory; fromRow() loose-type + NULL-pid. **Divergence from the brief (flagged per instruction):** the prompt's explicit column list did NOT include `session_id`, but I added it (indexed, non-unique) + a `findBySessionId()` because (a) it matches the existing `Recorder::$activeTimeShifts` data model, and (b) the URL route key in `startTimeShift()`'s `stream_url` is the playback session id, which f-c's cross-worker lookup needs. PK stays `id CHAR(36)` with `findById()` as the primary lookup, exactly as specified. **Verification (actual):** `phpunit tests/Unit/LiveTv/TimeShift/DbTimeShiftSessionStoreTest.php` → **16/16 pass (53 assertions)**. Store + MigrationRunner tests together → **42/42 pass**. `phpstan analyse -c phpstan.neon.dist` on all 3 new PHP files → **0 errors** (L9). `phpcs --standard=PSR12` on all 3 → **0 errors**. Migration 078 parsed through the real `MigrationRunner::splitStatements()` → **1 clean CREATE TABLE statement** (comments stripped, no spurious semicolon split). Committed `4f7d2c89`, pushed to origin/master. **Next (out of scope here):** f-b spawns the detached ffmpeg rolling buffer into `buffer_dir`, persists the child `pid` via `updatePid()`, and advances `updateBufferWindow()`; then wires the store into the DI provider with the real consumer. f-c replaces the `LiveTvStreamController` 501 stub, resolving a session (by session_id / id) and serving from `buffer_dir` via `withFile`/HLS. ## Implementer — SV-3.1 f-b (rolling time-shift buffer writer + store-backed cross-worker sessions) — 2026-07-13 Second sub-step of SV-3.1 **f**. Turns `Recorder`'s metadata-only time-shift stub into a REAL on-disk rolling buffer writer, persisted via f-a's `DbTimeShiftSessionStore` so a session started on one worker is resolvable on any other. Consumes f-a (`4f7d2c89`); does NOT touch the `LiveTvStreamController` 501 stub (that's f-c). **Buffer approach chosen — HLS rolling window (no prune Timer).** `startTimeShift()` spawns a DETACHED ffmpeg via the same nohup/`timeout`/`echo $!` machinery as `spawnRecording()` (extracted into a shared `launchDetached()` helper), writing: `ffmpeg -y -hide_banner -loglevel error -i -c copy -f hls -hls_time 6 -hls_list_size -hls_flags delete_segments+append_list -hls_segment_type mpegts -hls_segment_filename /seg_%05d.ts /buffer.m3u8`. Windowing math: `N = ceil(TIMESHIFT_BUFFER_SECONDS(7200) / TIMESHIFT_SEGMENT_SECONDS(6)) = 1200` segments ⇒ `N * hls_time ≈ 7200s ≈ 2h`. `delete_segments` auto-prunes older segments, so there is **no separate prune Timer** (avoids the SV-0.5 timer-storm class entirely). Constants added: `TIMESHIFT_SEGMENT_SECONDS=6`, `TIMESHIFT_PLAYLIST_NAME='buffer.m3u8'`. The detached process is bounded by the same `transcode_timeout` wrapper as recordings so a never-stopped capture cannot hold a tuner forever. **How `startTimeShift()` now works:** tear down any prior session for the playback session (idempotent restart) → generate the time-shift UUID → create per-session buffer dir at `/timeshift/` → resolve the tuner URL via `resolveTunerStreamUrl()` → spawn the rolling HLS buffer → build a `TimeShiftSession` (id, session_id, channel_id, buffer_dir, real pid, buffer_start_at/end_at, window_seconds=7200, status=active) and `save()` it to the store (failure-safe) → keep the in-memory `$activeTimeShifts` fast-path entry (now also carrying `buffer_dir`/`pid`). Failure-safe: no tuner (or spawn returns 0) ⇒ session persisted with a NULL pid and empty buffer, never throws; the return contract `{time_shift_id, stream_url, buffer_start, buffer_end}` is unchanged. **How `stopTimeShift()` now works:** resolves the session cross-worker (`findBySessionId`, falling back to the in-memory entry) → `terminateRecording($pid)` (SIGTERM→SIGKILL, coroutine-guarded, works cross-process on the same host; a missing/dead pid resolves instantly) → `removeBufferDir()` (recursive delete, **path-jailed** under `/timeshift/` via a string-prefix + realpath check so a spoofed buffer_dir can't delete anything outside the subtree; a missing dir is a no-op) → `delete()` the store row → unset the in-memory entry. Every step is failure-safe (try/catch + guards). Returns true if a session existed in memory OR the store. **Cross-worker read:** `getTimeShift()` now falls back to the store (`findBySessionId`) when this worker has no in-memory entry, mapping the row to the same array shape existing consumers expect (so f-c can resolve `buffer_dir` by session_id from any worker; a `stopped` store row returns null). Left `seekTimeShift()`/`getTimeShiftPosition()` on the in-memory model deliberately — the store's `cursor_position` is a buffer-offset while those use a live epoch timestamp; reconciling the two cursor semantics is f-c's call, so I did not introduce a mismatched cross-worker cursor here. **DI wiring (landmine-safe):** bound `DbTimeShiftSessionStore` as an EXPLICIT factory in `LiveTvServicesProvider` and injected it as a **NON-NULLABLE** `Recorder` ctor dependency (constructor param #2, before the optional params) — sidestepping the "PHP-DI skips optional nullable ctor params" landmine (§0.3). The Recorder factory now resolves the store and passes it. **Dual-entrypoint check:** neither `public/index.php` nor `start.php` constructs `Recorder`/ `LiveTvManager` directly — both resolve `LiveTvManager` from the shared `ContainerFactory` (which registers this provider), and `Application::getLiveTvStreamController()` gets the Recorder via `LiveTvManager::getRecorder()` — so the single provider change covers both entrypoints; nothing to mirror. Provider docblock updated. **Files changed:** - `src/LiveTv/Recorder.php` — imports; new non-nullable `$timeShiftStore` ctor dep + property; `TIMESHIFT_SEGMENT_SECONDS`/`TIMESHIFT_PLAYLIST_NAME` consts; rewrote `startTimeShift()`/ `stopTimeShift()`/`getTimeShift()`; new `spawnTimeShiftBuffer()` (protected seam), `launchDetached()` (shared detached-spawn helper, `spawnRecording()` refactored onto it), `timeShiftBufferDir()`/`timeShiftRoot()`/`removeBufferDir()` (path-jailed) helpers. - `src/Common/Container/Providers/LiveTvServicesProvider.php` — `DbTimeShiftSessionStore` factory binding + injected into the Recorder factory (non-nullable); docblock. - `tests/Unit/LiveTv/RecorderTimeShiftBufferTest.php` — NEW: 7 tests (spawn+persist; no-tuner null-pid/no-spawn; stop terminates+cleans+deletes-store; stop failure-safe when dir gone; stop false when neither; getTimeShift cross-worker store fallback; getTimeShift null for stopped row). Spawn stubbed via mock-builder `onlyMethods(['spawnTimeShiftBuffer'])` (RecordingSchedulerTest pattern) so no real ffmpeg runs. - `tests/Unit/Common/Container/Providers/LiveTvServicesProviderTest.php` — NEW DI-wiring test: the resolved Recorder carries a NON-NULL `DbTimeShiftSessionStore` (reflection), same shared singleton via manager/direct/`DbTimeShiftSessionStore::class`. - Constructor-arg updates for the store in `RecorderTest`, `RecorderTimedStopTest`, `RecorderRecoveryTest`, `RecorderPlainArrayReadPathTest`, `RecordingSchedulerTest`. **Verification (actual):** `phpunit tests/Unit/LiveTv/ + LiveTvServicesProviderTest` → **344 tests / 884 assertions / 0 failures**; the new buffer test alone → **7/7 (40 assertions)**. phpstan L9 (`-c phpstan.neon.dist`) on all 9 changed files → **0 errors**. phpcs PSR12 on all changed files → **0 errors, 0 warnings** (the 2 remaining `Recorder.php` >120-char warnings are PRE-EXISTING on HEAD at the comskip closure + `getStorageStats` docblock — confirmed via phpcs on `git show HEAD:` — not introduced here). **For f-c (controller) to match:** the buffer is served as an HLS rolling playlist — `buffer.m3u8` + `seg_%05d.ts` segments in `buffer_dir` (NOT a single `.ts`). f-c should resolve the session cross-worker (via the store / `getTimeShift()` which now falls back to it), then serve `buffer_dir/buffer.m3u8` + segments (define the seek/cursor semantics against the store's `cursor_position` — left untouched here). A no-tuner session has a NULL pid and empty buffer dir, so f-c must handle a not-yet-populated playlist gracefully. ## Implementer — SV-3.1 f-c (serve timeshift HLS buffer + segment route + fix recording-stream Range) — 2026-07-13 Final sub-step of SV-3.1 **f**. Replaces the `LiveTvStreamController::streamTimeShift()` 501 stub with real HLS serving of f-b's rolling buffer, adds the segment route, and fixes the recording-stream Range gap. Touched the controller + routes only (Recorder/store/migration untouched — f-a/f-b own those). **How `streamTimeShift()` serves now:** resolves the session **cross-worker** via `Recorder::getTimeShift($sessionId)` (which falls back to the DB-backed store, so a session started on any worker resolves) → pulls `buffer_dir` from the returned row → if the session is null/stopped or `buffer_dir` is blank → **404** → if the session is valid but `buffer.m3u8` hasn't been written yet (no-tuner NULL-pid/empty dir, or ffmpeg is still starting) → **503 + `Retry-After: 2`** "buffer not ready" (never a 500 on the missing file) → otherwise delegates to the existing `TranscodeFileServer::serveJobFile()` trait, which streams `buffer.m3u8` via `withFile()` with `Content-Type: application/vnd.apple.mpegurl` + `Cache-Control: no-cache`. The rolling HLS window IS the seekable timeshift buffer (client-side HLS seeking); **no server-side cursor seek was built** (out of scope; f-b left `seekTimeShift`/`getTimeShiftPosition` on the in-memory model deliberately). **Segment route + path-jail:** new handler `streamTimeShiftSegment()` on route `GET /livetv/timeshift/{sessionId}/{segment}`. **SECURITY — the segment name is path-jailed with a strict allow-list regex `/^seg_\d+\.ts$/D` (the `D`/PCRE_DOLLAR_ENDONLY modifier is deliberate — without it `$` also matches before a trailing `\n`, so `"seg_1.ts\n"` would slip through).** The jail runs FIRST, before the session is even resolved and before any name touches the filesystem — traversal (`../`), absolute paths, the playlist itself, wrong extensions, prefix/suffix junk, and a trailing newline are all rejected with 404. Only a name ffmpeg actually emits reaches `serveJobFile()`, which then applies a SECOND-layer `isSafeFilename()` check and streams the segment via `withFile()` with `video/mp2t` + immutable caching + HTTP Range (206/416). A validly-named-but-aged-out segment (pruned by ffmpeg's `delete_segments`) resolves to a missing file → 404. **Route ordering (Router correctness):** registered `/livetv/timeshift/{sessionId}/stream` BEFORE `/livetv/timeshift/{sessionId}/{segment}` in the same `loadStreamingRoutes()` group. Both are parametric (they carry `{sessionId}`), so the Router matches them by registration order (first `preg_match` wins) — the exact ordering the existing `/hls/{job}/playlist` → `/hls/{job}/{file}` pair already relies on. A `.../stream` request therefore always hits the playlist handler, never the segment handler. **`streamRecording()` Range fix:** the old code did `->status(200)->withFile($path)` with NO Range parsing, so a ranged seek got a full-file 200 on the CGI/`index.php` emit path. Added `serveRecordingFile()` mirroring the AudiobookController/ThemeMediaStreamController idiom: `ByteRangeParser::parse()` → 206 + `Content-Range` (`withFile($path,$start,$len)`) / 416 / full 200. Deliberately set NO immutable cache header (an `status='recording'` `.ts` is still growing — must not be cached hard), so I hand-rolled the range path here instead of reusing `serveJobFile()`'s immutable-segment caching. **Signed-URL prefix authorization (necessary for the segment route to actually work for signed-URL clients):** `SignedUrl::canonicalResource()` only prefix-collapsed `/hls/**` and `/dash/**`, so a signed `/livetv/timeshift/{id}/stream` URL authorised ONLY the exact playlist path — every `seg_NNNNN.ts` request from a headerless/native/casting player (the exact class `SignedUrlMiddleware` exists for) would 401. Timeshift fans a playlist URL into segment requests exactly like HLS/DASH, so I extended the prefix regex to also collapse `/livetv/timeshift/[^/]+` → one signed playlist token now authorises all segments under that session. **The single-file recording stream `/livetv/recording/{id}/stream` stays exact-path-bound (no sub-segments).** This is the one change outside "controller + routes" — flagged for the cumulative review. In-browser hls.js is unaffected (it attaches the Bearer token per segment XHR — mechanism 1). **Files changed:** - `src/Server/Http/Controllers/LiveTvStreamController.php` — `use TranscodeFileServer` trait; `SEGMENT_NAME_PATTERN` const; rewrote `streamTimeShift()`; new `streamTimeShiftSegment()`, `resolveTimeShiftBufferDir()`, `serveRecordingFile()`; `streamRecording()` now Range-honoring. - `src/Server/Core/Application.php` — registered the segment route in `loadStreamingRoutes()` (same `SignedUrlMiddleware`+`StreamLimitMiddleware` group, after the `/stream` route). - `src/Auth/SignedUrl.php` — `canonicalResource()` prefix-collapses `/livetv/timeshift/{id}` (+ docblock). - `tests/Unit/Server/Http/Controllers/LiveTvStreamControllerTest.php` — NEW: 26 tests (streamRecording 200/206/416/400/404×3; streamTimeShift playlist-served/400/404-not-found/503-not-ready/404-blank-dir; segment full-200/206-range/404-aged-out/404-session-missing + an 11-case unsafe-name dataProvider proving the jail rejects BEFORE resolving the session). - `tests/Unit/Auth/SignedUrlTest.php` — +2 tests (timeshift prefix-scoping verify; canonicalResource timeshift-collapse + recording-exact). **Verification (actual):** - `phpunit LiveTvStreamControllerTest + SignedUrlTest` → **43 tests / 113 assertions / 0 failures**. - Broader regression `phpunit tests/Unit/LiveTv tests/Unit/Server/Http tests/Unit/Auth/SignedUrlTest.php` → **1105 tests / 3464 assertions / 0 failures / 6 skipped** (pre-existing coroutine/DB skips). - phpstan L9 (`-c phpstan.neon.dist`) on all 5 changed files → **0 errors**. - phpcs PSR12 → new controller + its test + `SignedUrl.php` **0/0**; the 4 `Application.php` + 1 `SignedUrlTest.php` >120-char warnings are **PRE-EXISTING on HEAD** (confirmed via phpcs on `git show HEAD:` — same warnings, only line numbers shifted by my inserts). **ACCEPTANCE mapping:** - Timeshift 501 stub → real HLS serving of the rolling buffer, cross-worker session resolution, 404 not-found, 503 not-ready. ✅ - Segment route + handler, path-jailed (`^seg_\d+\.ts$/D`, jail-before-fs), Range-honoring. ✅ - `streamRecording()` Range gap fixed (206 + Content-Range for ranged; 200 for full). ✅ - Routes registered in the `SignedUrlMiddleware`(+`StreamLimit`) group; both entrypoints share the `Application` router; Response emit paths (Workerman native + CGI `finalizeFileHeaders`) both honor Range.✅ - Tests (SV-3.1 h): `LiveTvStreamControllerTest` created. ✅ **FLAG for h-tests / cumulative review:** 1. **The segment path-jail** — `/^seg_\d+\.ts$/D` with the trailing-newline `D` guard is the primary defense; `serveJobFile()`'s `isSafeFilename()` is the second layer. Double-check both hold and that no caller reaches the filesystem with an unvalidated name. 2. **The `SignedUrl::canonicalResource()` change** is the one edit outside "controller + routes" — it's a direct mirror of the existing HLS/DASH prefix logic and is required for signed-URL native/casting clients to fetch timeshift segments; confirm it doesn't over-broaden (recording stays exact-path). 3. **Git NOT committed/pushed** by this Implementer per the CARDINAL RULE that the Phase Coordinator owns the git cycle. Working tree carries all 5 files. Intended commit message: `livetv: SV-3.1 f-c serve timeshift HLS buffer + segment route + fix recording-stream Range` ## Fixer — SV-3.1 f (close ALL f-a/f-b/f-c review findings) — 2026-07-13 Audit-and-complete pass over the landed f-a/f-b/f-c work (commits `4f7d2c89`/`b4afe671`/`5761e7e5`). Two logical commits. This section = COMMIT 1 (the MEDIUM cluster: schema / upsert-key / orphan window). ### COMMIT 1 — `livetv: SV-3.1 f fix: UNIQUE(session_id) + upsert-on-session_id + close orphan window` 1. **Migration 078 (`migrations/078_livetv_timeshift_sessions.sql`)** — replaced the plain `INDEX idx_session_id (session_id)` with `UNIQUE KEY uq_session_id (session_id)`. 078 is brand-new and NOT deployed anywhere (verified against the SV-4.9 migration ledger / no prod), so amended in place rather than a follow-up ALTER. No migration-list test asserts 078's columns (`MigrationRunnerTest` globs a tmpdir; no hard-coded 078 expectations) → still green. 2. **Store `save()` (`DbTimeShiftSessionStore.php`)** — now a genuine upsert keyed on BOTH unique keys (PK `id` + `UNIQUE(session_id)`). Dropped `session_id = VALUES(session_id)` from the SET-list (a no-op on a session_id collision), left `id` OUT of the SET-list (must never be rewritten on a session_id collision — that is what makes a restart overwrite the row instead of leaking a second PK-only-deduped row), and ADDED `updated_at = CURRENT_TIMESTAMP` so the timestamp advances even when `ON UPDATE CURRENT_TIMESTAMP` would not fire on an otherwise-identical row. 10 positional binds unchanged. 3. **Store `reapBySessionId(string): list`** — NEW. Returns EVERY row for a session_id (at most one under the UNIQUE constraint, but list-shaped as defence-in-depth for a crash/legacy duplicate set) so the caller can terminate every pid. `findById` kept. 4. **Store `findBySessionId()`** — simplified from `ORDER BY created_at DESC, id DESC LIMIT 1` (which could return the older of two same-second rows) to a plain `WHERE session_id = ?` unique lookup. 5. **Recorder `startTimeShift()` (`Recorder.php`)** — reordered to close the crash-orphan window: (a) `stopTimeShift()` tears down any prior session (now reaps ALL rows), (b) create buffer dir, (c) **persist the row with a NULL pid FIRST**, (d) spawn the detached ffmpeg, (e) `updatePid(id, pid)`. A crash between spawn and persist can no longer leave a running ffmpeg with no reapable DB record. In-memory fast path + `{time_shift_id, stream_url, buffer_start, buffer_end}` return contract unchanged; still failure-safe (no-tuner ⇒ null pid, no throw; a persist failure still best-effort spawns, bounded by the `timeout ` wrapper + the same-worker in-memory reap). 6. **Recorder `stopTimeShift()`** — now reaps ALL rows via `reapBySessionId()` (terminate each pid, clean each buffer dir, delete each row), with a persist-failure edge that reaps the same-worker in-memory entry when the store has no row. `terminateRecording`/`removeBufferDir` are idempotent. 7. **Recorder `getTimeShift()` shape drift (f-b finding 3)** — added `current_position` to the in-memory fast-path shape (seeded to `$now` in `startTimeShift`) so it and the store-fallback path now return the SAME keys; docblock updated to state the shapes match (was overclaiming a mirror). **Tests updated:** `DbTimeShiftSessionStoreTest` — `findBySessionId` now asserts NO `ORDER BY`/`LIMIT` + a not-found→null case; new `reapBySessionId` all-rows + false-result cases. `RecorderTimeShiftBufferTest` — round-trip mock now models the two-phase write (INSERT null pid → `UPDATE SET pid`), assertions prove persist-first (INSERT pid null, real pid via updatePid) and no-updatePid when nothing spawned. **Verification (COMMIT 1):** `phpunit DbTimeShiftSessionStoreTest + RecorderTimeShiftBufferTest + RecorderTest` → **42 tests / 131 assertions / 0 failures**; broader `phpunit tests/Unit/LiveTv + LiveTvStreamControllerTest + LiveTvServicesProviderTest` → **374 / 956 / 0 fail / 6 skip** (pre-existing coroutine/DB skips). phpstan L9 (`-c phpstan.neon.dist`) on `Recorder.php` + `DbTimeShiftSessionStore.php` → **0 errors**. phpcs PSR12 on all 4 changed src/test files → **0 errors**; the 2 remaining Recorder.php >120-char warnings (lines 233, 2037) are PRE-EXISTING on HEAD (confirmed via phpcs on `git show HEAD:`). ### COMMIT 2 — `livetv: SV-3.1 f tests+docs: injection/path-jail guards + shape + route-order + comment` 8. **Command-injection mutation guard (f-b MEDIUM test-rigor)** — new `tests/Unit/LiveTv/RecorderTimeShiftSecurityTest.php`. Exercises the REAL `spawnTimeShiftBuffer()` command builder (NOT stubbed) with 4 hostile URL/dir data sets (`http://x/;touch /tmp/pwn`, `$(id)`, spaces/pipe/amp, backticks/quotes). To capture the emitted command WITHOUT executing a shell, `Recorder::launchDetached()` was changed `private`→`protected` (pure test seam, no behaviour change) and a test subclass overrides it to capture `$ffmpegCmd`. Asserts every interpolated value (ffmpeg binary, tuner URL, segment pattern, playlist path) appears ONLY in its `escapeshellarg`-quoted form + the raw `-i ` never appears unquoted. **Mutation proof:** reverting line 1116 `escapeshellarg($streamUrl)` → raw `$streamUrl` flipped ALL 4 data sets RED (e.g. `... -i http://x/;touch /tmp/pwn -c copy ...` reached the command line); restored → 4/4 green. 9. **Path-jail negative test (f-b LOW)** — same file. Invokes the private `removeBufferDir()` via reflection with (a) a plain out-of-jail absolute path (string-prefix guard) and (b) a traversal `/../victim` that string-prefixes the root but resolves outside it (realpath guard); asserts an out-of-jail `secret.txt` survives both, and that a legitimate in-jail buffer dir IS removed (proving the guard is not a blanket no-op). **Mutation proof:** neutering both jail early-returns (`if (false)`) flipped the test RED (the out-of-jail victim's `secret.txt` was deleted); restored → 5/5 green. 10. **Store test gaps (f-a LOW)** — `DbTimeShiftSessionStoreTest`: `findBySessionId` not-found→null (landed in COMMIT 1 with the lookup simplification), `TimeShiftSession::toArray()` full-column round-trip, and a non-null-pid `save()` bind-path test asserting `updated_at = CURRENT_TIMESTAMP` is in the set-list, the PK `id` is NOT, and pid binds as an int. 11. **f-c cosmetic** — `src/Server/Core/Application.php` (~:1464): reworded the comment that called the parametric `/livetv/timeshift/{sessionId}/stream` route "static". Both timeshift routes carry `{sessionId}` and are therefore matched by regex in REGISTRATION ORDER, not via the Router's O(1) static-route map; the comment now says so. 12. **Route-ordering test (f-c LOW)** — `RouterTest`: two Router-level tests prove `.../stream` dispatches to the playlist handler and `.../seg_00001.ts` to the segment handler when registered in the Application order (stream first). Guards against a future re-ordering regression. (phpcbf also normalised 2 pre-existing `function(` whitespace errors + the EOF newline in that file → phpcs 0.) **Verification (COMMIT 2):** `phpunit RecorderTimeShiftSecurityTest + DbTimeShiftSessionStoreTest + RouterTest` → **32 / 105 / 0 fail**; full affected set `phpunit tests/Unit/LiveTv + RouterTest + LiveTvStreamControllerTest + LiveTvServicesProviderTest` → **387 / 1010 / 0 fail** (0 skip). phpstan L9 (`-c phpstan.neon.dist`) on `Recorder.php` + `Application.php` + all 3 test files → **0 errors**. phpcs PSR12 on all 5 changed files → **0 errors** (the 4 remaining Application.php >120-char warnings are PRE-EXISTING on HEAD, none in the edited comment range). Both mutation-revert proofs (items 8 + 9) confirmed RED-on-revert, green-on-restore. **Cumulative-review notes (for the integration reviewer):** - `startTimeShift` still best-effort spawns even if the persist-first `save()` throws (DB down); the running ffmpeg is then bounded only by the `timeout ` wrapper + the same-worker in-memory reap. This is the deliberate failure-safe trade-off (no-throw contract); the crash-orphan window the fix targets — a crash BETWEEN spawn and persist — is closed because the row now precedes the process. - `getTimeShift`'s two paths now share KEYS; the `current_position` VALUE semantics still differ (in-memory epoch seed vs store `cursor_position` buffer-offset) — that reconciliation was explicitly deferred by f-b as an f-c concern and is unchanged here (f-c only reads `buffer_dir`). - Migration 078 is amended in place (UNIQUE constraint); it is not deployed anywhere, so no follow-up ALTER is needed. On-box DVR end-to-end verification of the timeshift path remains owed (sandbox has no tuner), consistent with the rest of the DVR stack's outstanding on-box verification. ## Reviewer (cumulative) — SV-3.1 f (store + buffer-writer + controller + fix, as one system) — 2026-07-13 Integration-level review of the whole timeshift feature (commits `4f7d2c89` / `b4afe671` / `5761e7e5` / `3b5c0c6f` / `f6133701`) against HEAD. Focus = SEAMS across the four pieces, not per-piece re-litigation. **2 findings.** ### Field-shape / path seams — verified clean - Store→getTimeShift→controller `buffer_dir` hop lines up: `startTimeShift` writes the SAME `$bufferDir` into both the store row and the in-memory entry; `getTimeShift` returns it under `buffer_dir` on both paths; the controller reads only `buffer_dir`. The playlist/segment names the writer emits (`Recorder::TIMESHIFT_PLAYLIST_NAME` `buffer.m3u8`, `seg_%05d.ts`) are exactly what `streamTimeShift`/`streamTimeShiftSegment` check (`Recorder::TIMESHIFT_PLAYLIST_NAME`, `SEGMENT_NAME_PATTERN=/^seg_\d+\.ts$/D`) — no constant drift. - Windowing is internally consistent: `TIMESHIFT_BUFFER_SECONDS=7200`, `TIMESHIFT_SEGMENT_SECONDS=6`, `hls_list_size=ceil(7200/6)=1200`, `1200*6≈7200s`; migration `window_seconds` DEFAULT 7200 and the `TimeShiftSession(window_seconds: TIMESHIFT_BUFFER_SECONDS)` construction all agree. No off-by-one. - Segment path-jail is layered and jails BEFORE the fs (regex → `serveJobFile`'s `isSafeFilename` → `is_file`); `$dir` (buffer_dir) is server-authored (never user input — the URL only supplies the DB-lookup key `sessionId` and the jailed `segment`), so `serveJobFile` not re-jailing `$dir` is safe. - `SignedUrl::canonicalResource` prefix-collapse `/livetv/timeshift/[^/]+` scopes one signed token to exactly one session's playlist+segments, and leaves `/livetv/recording/{id}/stream` exact-path-bound. Route order (`/stream` before `/{segment}`, both parametric, first-match-wins) is correct + tested. ### Fixer-flagged items — adjudicated - **(a) DB-down best-effort spawn:** ACCEPTABLE. If `save()` throws, the spawned ffmpeg is bounded by the `timeout ` wrapper and is reapable via the same-worker in-memory entry; this is strictly no worse than the pre-f state (timeshift was a 501 stub with zero persistence). Not a finding on its own — but see Finding 1, which is a DIFFERENT persist-path defect. - **(b) `current_position` value semantics differ (epoch seed vs `cursor_position` offset):** DORMANT / not a live bug. No current consumer reads the store-path `current_position`: the controller reads only `buffer_dir`; `getTimeShiftPosition()`/`seekTimeShift()` touch ONLY the in-memory array. Safe while server-side seek is deferred; a future cross-worker seek consumer would need to reconcile it. - **(c) on-box e2e:** genuinely owed (no tuner in sandbox); note only. ### FINDINGS 1. **[High — resource leak, concurrency-gated] `Recorder::startTimeShift()` (`src/LiveTv/Recorder.php` ~1748-1790) + `DbTimeShiftSessionStore::save()` (~62-93): the two-phase persist and the `UNIQUE(session_id)` upsert collide — under two concurrent same-`session_id` starts the fresh caller's `updatePid()` targets a row id the upsert discarded, orphaning a tuner-holding ffmpeg and leaking its buffer dir.** - The seam: `save()` is `INSERT … ON DUPLICATE KEY UPDATE` and deliberately keeps `id` OUT of the SET-list, so on a `session_id` collision the PRE-EXISTING row's `id` survives. But `startTimeShift` persists with a fresh `$timeShiftId`, then does the second-phase `updatePid($timeShiftId, $pid)` keyed on that SAME fresh id. When the fresh caller's `save()` was the one that collided (the other start inserted first), the surviving row carries the OTHER start's id, so `updatePid($timeShiftId)` matches ZERO rows and the real capture pid is never persisted. - Concrete failure (two workers, same session A, `stopTimeShift` reap-all runs on both before either `save()`): W1 `save(idW1,dirW1)` INSERTs; W2 `save(idW2,dirW2)` collides→upsert leaves row `idW1 / dirW2 / pid null`; W1 `updatePid(idW1,pidW1)`→row `idW1/dirW2/pidW1`; W2 `updatePid(idW2,pidW2)`→0 rows. Now pidW2 (writing dirW2) has no DB record. A later `stopTimeShift(A)` reaps only `idW1` → kills pidW1, `removeBufferDir(dirW2)`, deletes the row — leaving **pidW2 running to `transcode_timeout` (up to 2h) holding a scarce tuner and writing an unlinked (dirW2 deleted) file that pins disk**, plus **dirW1 never cleaned** (the row's `buffer_dir` was overwritten to dirW2, so dirW1's id was never persisted as its own reapable row). - Why it matters: this is exactly the "leak an ffmpeg process, a buffer dir, or a DB row" the cross-worker machinery is supposed to prevent — and that machinery (persist-first, cross-worker store, `UNIQUE(session_id)`) exists precisely because same-session requests DO land on different workers/coroutines, so the race is reachable (double-tap, client retry, reconnect, or coroutine interleaving at the `save()` I/O yield on a single worker). The sequential restart path is safe (`stopTimeShift` DELETEs the old row first, so `save()` is a clean INSERT and `updatePid` matches) — the defect is strictly the concurrent interleaving. Suggested direction: after `save()`, re-resolve the surviving row's id by `session_id` before `updatePid` (or make `updatePid` key on `session_id`, or fold the pid into the initial upsert once known) so the second phase always targets the row that actually survived the upsert. 2. **[Medium — cross-worker correctness seam] `Recorder::getTimeShift()` (`src/LiveTv/Recorder.php` ~1911-1915): the in-memory fast path is preferred unconditionally and is never invalidated cross-worker, so a stale entry on the originating worker shadows the authoritative store after a cross-worker restart → persistent 503/404 for that session on that worker.** - The seam: `getTimeShift` returns `$this->activeTimeShifts[$sessionId]` whenever present, WITHOUT revalidating the buffer_dir/pid against the store. A timeshift restart that lands on a DIFFERENT worker (W2) deletes the original row + dir1 and creates dir2, but never touches W1's in-memory entry (W1 gets no `stopTimeShift(A)`). W1's entry still points at the deleted dir1. - Concrete failure: after such a restart, any `/livetv/timeshift/A/stream` request routed to W1 resolves `buffer_dir=dir1` (gone) → `is_file(dir1/buffer.m3u8)` false → 503 `Retry-After:2` forever on W1 (segment requests → 404), while W2/other workers (store fallback → dir2) serve the live buffer. Playback becomes flaky/broken on 1-of-N workers for that session. No resource leak (the restart's `stopTimeShift` correctly reaped dir1/pid via the store), purely a stale-read correctness issue. Partially mitigated by HTTP keep-alive pinning a browser's requests to one worker, but native/casting clients and connection churn defeat that — and cross-worker resolution is the feature's whole premise. Suggested direction: have the in-memory fast path revalidate (e.g. drop/ignore the entry when its `buffer_dir` no longer exists on disk, or fall through to the store) so a superseded same-worker cache cannot mask the authoritative row. ### Informational (not a defect — consistent with the established pattern) - Auth is id-as-capability: the SignedUrlMiddleware session-cookie branch authorizes ANY logged-in user who presents a valid `sessionId` (no per-user ownership check on the timeshift session), exactly as `/hls/{job}` and `/dash/{job}` already work (unguessable UUID = capability). Not introduced or regressed by SV-3.1 f; flagged only so the whole-feature gate is aware the timeshift `session_id` must remain unguessable to preserve that equivalence. ### Fixer (RECOVERY of an interrupted fix) — SV-3.1 f cumulative findings CLOSED — commit `46710df4` — 2026-07-13 Recovered a predecessor's fix that died mid-mutation-proof (session limit), leaving the work uncommitted. **On audit the on-disk tree was already correct and GREEN** — the predecessor had in fact restored the mutation-1b revert (session_id-keyed pid write) before dying; the LiveTv suite was already passing, so no un-restored mutation remained. Re-verified BOTH findings end-to-end against the live code rather than trusting the diff: - **Finding 1 [HIGH] — CLOSED.** (a) `Recorder::startTimeShift()` records the capture pid via the new `DbTimeShiftSessionStore::updatePidBySessionId($sessionId, $pid)` (WHERE `session_id = ?`), so it always lands on the row `findBySessionId()`/`getTimeShift()` resolve — never zero rows. (b) The pre-spawn write is now the new collision-detecting `claim()` (plain INSERT, not the silent `save()` upsert); backed by migration 078 `UNIQUE KEY uq_session_id`. A racing loser (`$claimed === false`) returns `existingTimeShiftResponse()` BEFORE the `mkdir` + spawn — no orphaned ffmpeg, no leaked buffer dir. `save()`/`updatePid()` are no longer called from `src/` (kept as tested store methods). - **Finding 2 [MEDIUM] — CLOSED.** `getTimeShift()` self-validates the in-memory fast path with `is_dir($bufferDir)`; a reclaimed/missing dir `unset()`s the entry and falls through to the store, so a cross-worker restart no longer shadows the authoritative row (no persistent 503/404 on 1-of-N workers). A valid cached dir still returns from memory with no DB read. Return contract `{time_shift_id, stream_url, buffer_start, buffer_end}` and failure-safe best-effort-spawn (genuine DB error still spawns) preserved. §0.3 conventions honored (positional binds, SELECT-first re-resolve in `claim()`, no loop-blocking — single cheap `is_dir()` stat). **Mutation-revert proofs (each reverted uncommitted → RED → restored → green):** 1. session_id-keyed pid write: `updatePidBySessionId($sessionId,$pid)` → id-keyed `updatePid($timeShiftId,$pid)` ⇒ `testCapturePidRecordedOnSessionIdKeyedRow` **RED** ("'UPDATE … WHERE id = ?' … does not contain 'session_id = ?'"). 2. lost-claim abort: `if (!$claimed)` → `if (false)` ⇒ `testConcurrentDuplicateStartLosesClaimAndDoesNotSpawn` **RED** (loser spawned a second ffmpeg — `$spawnCalls` non-empty). 3. `is_dir` invalidation: dropped `&& is_dir($bufferDir)` ⇒ `testGetTimeShiftInvalidatesStaleInMemoryEntryAndFallsThroughToStore` **RED** (returned the stale `gone-dir1` instead of the live `live-dir2`). **Verification (actual):** `phpunit tests/Unit/LiveTv/ --no-coverage` → **OK — 374 tests, 972 assertions, 6 skipped (pre-existing), 0 failures**. `phpstan analyze -c phpstan.neon.dist` (L9) on all 4 changed files → **[OK] No errors** (removed one redundant `assertIsArray` that tripped `method.alreadyNarrowedType` after an `assertNotNull` — non-load-bearing test cleanup). `phpcs --standard=PSR12` on all 4 changed files → **clean** (the 2 pre-existing >120-char warnings in `Recorder.php` at lines 233/2131 are outside the changed hunks). Fix committed `46710df4`. ## TestEngineer — SV-3.1 h2 (storage accounting) — 2026-07-13 Closed the SV-3.1 **g** gap: storage accounting was functionally DONE but had **zero** test coverage. New file `tests/Unit/LiveTv/RecorderStorageAccountingTest.php` (commit **`6de8d089`**), no `src/` change (no test seam needed — the accounting surface was already unit-testable via a mocked `Connection` + reflection for the private helpers). DB mocked with the **production plain-array** shape `RowQuery` actually receives (not the `ResultSet` cursor), plus real temp dirs so `disk_free_space()` returns real values. **Covered (7 methods):** `hasRealDiskSpace()` (5% margin pass/fail + fail-open when `disk_free_space()` returns false — the intended, code-verified behavior), `estimateRecordingSize()` (exact ~2 MB/min math: 1min→2 MiB, 30min→60 MiB, 60min→120 MiB, 0→0), `getUsedStorageBytes()` (asserts `SUM(storage_size)` SQL + `status=completed` param; NULL total and empty result → 0; models MySQL SUM's numeric-STRING return), `getAvailableStorageBytes()` (PHP_INT_MAX when unlimited + never-queries guard; max−used; clamp-to-zero over budget), `getStorageStats()` (available == max−used invariant, GROUP BY status counts), and the `startRecording()` storage gate (refused → FAILED 'Insufficient storage space', **no** status→ recording transition i.e. no ffmpeg spawn; + a counterpart that proves the gate PASSES when space is available, failing downstream at the tuner with 'No tuner available'). **Verification (actual output):** - New file: `phpunit RecorderStorageAccountingTest` → **OK (15 tests, 39 assertions)**. - Broader LiveTv subset: `phpunit tests/Unit/LiveTv/` → **OK, 365 tests, 939 assertions, 6 skipped (pre-existing), 0 failures** — no regression. - `phpstan analyze -c phpstan.neon.dist` (L9, src) → **[OK] No errors**; phpstan L9 on the new test file → **[OK] No errors**. - `phpcs --standard=PSR12 tests/Unit/LiveTv/RecorderStorageAccountingTest.php` → **clean (exit 0)**. **Mutation-revert confirmations (2 highest-value guards — actually reverted, ran, reverted back):** - **5% margin:** changing `$usableSpace = (int)($freeSpace * 0.95)` → `* 1.0` in `Recorder::hasRealDiskSpace()` flips `testHasRealDiskSpaceReservesFivePercentMargin` **RED** ("Failed asserting that true is false"). Restored to `* 0.95` → green. - **startRecording gate:** neutralizing `if (!$this->hasStorageSpace(...))` → `if (false)` flips `testStartRecordingRefusedWhenStorageInsufficient` **RED** ("Failed asserting that an array contains 'Insufficient storage space'" — falls through to the tuner path). Restored → green. Result: **GREEN.** Note carried along in this worklog: the pre-existing uncommitted **Reviewer (cumulative) — SV-3.1 f** entry above (2 findings, stable ~4 min, complete) was swept into the worklog commit per the documented orchestrator-sweep pattern; it is unrelated to these tests and still owed a Fixer pass. --- ## Implementer — SV-3.6d (paginate Trakt watched-history sync) — 2026-07-13 **Scope (exactly this, nothing else):** make `reconcileWatchedHistory` walk the user's FULL watched history instead of only page 1 (`getWatchedHistory($user,1,100,$token)`). Did NOT touch resume positions (3.6c), the HTTP transport (3.6b), the Timer wiring (3.6a), `getPlaybackProgress` (not paginated by Trakt — left single-shot), or `syncPhlixToTrakt`. **How the page count is surfaced (return-shape change + new HTTP-client sibling):** - The 3.6b client decodes the JSON body and DISCARDS the PSR-7 response inside `HttpClient::request()`, so `X-Pagination-Page-Count` was not reachable by the caller. I added a sibling `HttpClientInterface::getWithHeaders()` returning `array{body, headers}` (headers lowercased for case-insensitive lookup). `HttpClient::request()` is now a thin wrapper over a new `requestWithHeaders()` (identical transport + 401/429/4xx status handling); a new `extractHeaders()` flattens the PSR-7 response headers on BOTH transports (async PSR-7 + cURL fallback). `get()`/`post()` are unchanged (`get()` still used by the untouched `getPlaybackProgress`). - `TraktApi::getWatchedHistory()` now returns `array{items: array, pageCount: int}` (was `array`) — it calls `getWithHeaders()`, parses `x-pagination-page-count` via a new `extractPageCount()` (returns 0 when the header is absent/unparseable = "unknown"). I chose the explicit struct return over an out-param because it makes the total-page contract first-class and directly assertable; the only test asserting the raw return was updated (see below). The 429 exponential-backoff retry loop is unchanged. **Page loop + backoff + defensive cap (`TraktHistorySync::reconcileWatchedHistory`):** - Rewrote the single-shot fetch into a `while(true)` page loop. Page 1 learns the reported page count and narrows the effective upper bound to `min(reported, MAX_HISTORY_PAGES)`; pages 2..N are fetched and reconciled with the SAME per-item logic (extracted verbatim into a new `reconcileWatchedPage()` helper — the last-write-wins / don't-downgrade-completed / duration logic is byte-for-byte the same). - **Layered, defensive termination:** (1) a short/empty final page (`count < limit`) ends the walk — this is ALSO the loop-until-short-page fallback that keeps a MISSING/malformed header from truncating (pageCount 0 keeps the bound at the cap and short-page terminates); (2) the reported page count bounds the loop; (3) a hard `MAX_HISTORY_PAGES = 200` cap (≈20,000 items at the 100/page size) guarantees the loop can't spin forever on a malformed header — a hit is logged (warning). A reported count exceeding the cap is logged + truncated. - **Backoff:** new `sleepBetweenPages()` mirrors the EXACT 3.6b 429 idiom — `\Co\sleep(0.25)` when `function_exists('\Co\sleep')`, else `usleep`. `INTER_PAGE_DELAY_MS = 250`. Verified the pull runs inside the Swoole `Coroutine::create()` (safeCall) Timer callback wired by 3.6a (start.php:284-291), so `\Co\sleep` yields the event loop — no blocking sleep on the resident worker. - A per-page fetch failure now logs the page number + items-written-so-far and BREAKS, PRESERVING earlier pages' writes (previously a page-1 failure returned 0; multi-page partial progress is now kept). - `syncTraktToPhlix($profileId): int` unchanged — still returns the TOTAL across all pages (loop sums). **Tests updated (why):** - `MockHttpClient` (in `TraktApiTest.php`) gained `getWithHeaders()` + an optional parallel `$headerResponses` queue (new interface method — mock MUST implement it). - `testGetWatchedHistoryReturnsArray` → renamed `testGetWatchedHistoryReturnsItemsAndPageCount`: asserts `$result['items']` + `pageCount` from an injected `x-pagination-page-count: 3` header (return shape changed). Added `testGetWatchedHistoryPageCountDefaultsToZeroWhenHeaderAbsent`. `testGetWatchedHistoryUsesCorrectEndpoint` needed no change (asserts only method/URL, which `getWithHeaders` still records). The multi-page `reconcileWatchedHistory` loop test belongs to 3.6e (needs the mocked-TraktApi + WatchHistory harness that step builds); my change is covered at the `getWatchedHistory` level. **Verify (verbatim):** - `phpstan analyse -c phpstan.neon.dist --level=9 --memory-limit=512M --no-progress` → **[OK] No errors**. - `phpcs --standard=PSR12 src/Plugins/Scrobbler/Trakt/` → **0 ERRORS** (only pre-existing line-length WARNINGS on unchanged signatures: TraktHistorySync:409 `syncPhlixToTrakt`, TraktApi:408 `getWatchedHistory` sig, TraktApi:678, TraktPlugin:470/78 — none introduced by 3.6d). - `phpunit --filter Trakt --no-coverage` → **OK (64 tests, 133 assertions)** (was 63; +2 new, -1 renamed). **⚠️ CORRECTNESS OBSERVATION (out of 3.6d scope — for reviewer/fixer, re-confirming 3.6b/3.6c notes):** The Trakt client sends **NO `trakt-api-key` (client id) and NO `trakt-api-version: 2` headers** on ANY request. `HttpClient::request()` sends only `User-Agent`, `Content-Type`, `Accept` + the caller's headers (`getWatchedHistory` adds only `Authorization: Bearer`). Trakt's API MANDATES both `trakt-api-key` and `trakt-api-version` on every call — without them requests are rejected, so the pull sync (this step included) cannot actually succeed against live Trakt regardless of pagination. Grep for `trakt-api-key`/`trakt-api-version` across `src/Plugins/Scrobbler/Trakt/` returns nothing. NOT fixed here (out of scope); flagging for a dedicated fix — the `clientId` is already available on `TraktApi` (ctor `$clientId`), so the fix is to inject those two headers into the request headers (likely at the `getWatchedHistory`/`getPlaybackProgress`/scrobble call sites or a shared header builder). **Files touched (absolute):** - `/home/sites/phlix/phlix-server/src/Plugins/Scrobbler/Trakt/HttpClientInterface.php` - `/home/sites/phlix/phlix-server/src/Plugins/Scrobbler/Trakt/HttpClient.php` - `/home/sites/phlix/phlix-server/src/Plugins/Scrobbler/Trakt/TraktApi.php` - `/home/sites/phlix/phlix-server/src/Plugins/Scrobbler/Trakt/TraktHistorySync.php` - `/home/sites/phlix/phlix-server/tests/Unit/Plugins/Scrobbler/Trakt/TraktApiTest.php` **Git:** deferred to the Phase Coordinator per Implementer CARDINAL RULES (I edit + verify only; the coordinator owns the git cycle). Tree is the 5 files above (+ this worklog). Requested commit message: `scrobbler: SV-3.6d paginate Trakt watched-history sync (X-Pagination-Page-Count + backoff)`. --- ## Implementer — SV-3.6c (reconcile Trakt resume positions + last-write-wins) — 2026-07-13 **Scope (exactly this, nothing else):** stop force-writing `STATUS_COMPLETED` for every reconciled Trakt item; pull in-progress playback from Trakt and reconcile it into local resume positions; use `parseWatchedAt()`/`paused_at` for last-write-wins. Did NOT touch pagination (3.6d — `getWatchedHistory` is still hardcoded `page=1,limit=100`), the HTTP transport (3.6b), the Timer wiring (3.6a), or tests (3.6e). No new tests added here. **Local watch-state/progress model (for the reviewer):** `Phlix\Auth\WatchHistory` → `watch_history` table (mig 002). Per (profile_id, media_item_id) row: `position_ticks` (int), `duration_ticks` (int|null), `progress_percent` (float 0-100), `playback_status` ENUM(playing/paused/stopped/completed), `last_watched_at` (TIMESTAMP — the comparable "last updated" field), `completed_at`. Tick scale: **10000 ticks = 1s** (`TICKS_PER_SECOND`). `updateProgress($profile,$item,$posTicks,$durTicks,$status)` DERIVES `progress_percent` from position/duration and auto-promotes to COMPLETED at ≥90%; it **always** stamps `last_watched_at = date('Y-m-d H:i:s')` (now, PHP default TZ) and does NOT accept an external event time. This is the model I reconcile INTO — I did not invent a parallel store. Duration for an item lives in `watch_history.duration_ticks` (once played) or `media_items.metadata_json.duration_seconds` (ffprobe container duration, seconds — persisted by the scanner, read by `MediaItemShaper`); `media_items` has NO duration column. **Files changed (2):** - `src/Plugins/Scrobbler/Trakt/TraktApi.php` — added `getPlaybackProgress(string $accessToken = '', ?string $type = null, int $limit = 100): array`, mirroring `getWatchedHistory()` VERBATIM (same Bearer auth via `$http->get`, same coroutine-safe client, same 429/5xx retry loop with jittered backoff + `\Co\sleep`/usleep-fallback, same exception handling). Endpoint `GET /sync/playback` (+ optional `/movies`|`/episodes`; other `$type` values ignored → all). It is OAuth-user-scoped (no username segment) and not paginated, so one request returns the full in-progress set — NOT a pagination loop. - `src/Plugins/Scrobbler/Trakt/TraktHistorySync.php` — split `syncTraktToPhlix()` into two fault-isolated reconcilers (each own try/catch, each returns its own count; a failure in one no longer zeroes the other — the old code returned 0 on any history-fetch error): - `reconcileWatchedHistory()` — fully-watched → `updateProgress(..., STATUS_COMPLETED)` **as before** but now GUARDED: skip if `isLocallyCompleted()` (idempotent) and skip if `!traktSupersedes()` (local `last_watched_at` newer than Trakt `watched_at`). `parseWatchedAt()` is now actually USED (was computed-then-discarded). - `reconcilePlaybackProgress()` — NEW: for each in-progress item, resolve local id via the SAME `findMediaItemId`/`findMediaItemIdByExternalId` path; extract `progress` (0-100, clamped); skip if `isLocallyCompleted()` (never downgrade completed→in-progress); apply last-write-wins on `paused_at`; resolve an absolute duration (local `duration_ticks` → metadata `duration_seconds`); write `updateProgress(profile,id, round(dur*pct/100), dur, STATUS_PAUSED)` — the model then derives the percent. NOT a forced 100%. - New helpers: `stringKeyedMap`, `parsePausedAt`, `parseTraktTimestamp` (parseWatchedAt now delegates to it), `traktSupersedes`, `parseLocalTimestamp`, `isLocallyCompleted`, `extractProgressPercent`, `resolvePlaybackDurationTicks`, `lookupDurationTicksFromMetadata`. Return-value semantics intact: still `int` = total items written (completions + resumes); the 3.6a timer logs it. **How last-write-wins is enforced:** `traktSupersedes($traktTs, $existing)` returns true only when the Trakt event time (`watched_at`/`paused_at`) is strictly newer than the existing local `last_watched_at`; both are parsed to absolute instants (`new \DateTimeImmutable` — Trakt strings carry a UTC offset; the local naive DATETIME is interpreted in PHP's default TZ, the same TZ `date()` wrote it in, so both are correct provided the process default TZ is stable within a deployment). If `$existing` is null (no local row) or has no comparable timestamp, the guard returns true but the separate `isLocallyCompleted()` status guard still prevents downgrading a completed item — so the fallback stays defensively correct. **Limitations (reported, not shipped-wrong):** 1. **Duration for resume positions is LOCAL-sourced.** Trakt's `/sync/playback` (and `/watched`) omit `runtime` unless `extended=full` is requested (this pull mirrors getWatchedHistory and does not). So a resume position is written only when a local duration is known (a prior local play, or the scanner's `duration_seconds`); an in-progress Trakt item whose local media item has never been played AND has no scanned duration is SKIPPED (logged debug) rather than persisting a wrong seek. The common last-write-wins case (Trakt vs a locally-known position) works. This also sidesteps the pre-existing `extractDurationTicks()` runtime-unit bug (Trakt runtime is MINUTES; that method treats it as seconds — harmless for the completed path where position==duration==X ⇒ any X gives the same status, but it would be wrong for a resume position, so the playback path does NOT use it). 2. **`updateProgress()` re-stamps `last_watched_at = now()`**, so after a reconcile the persisted local timestamp is "now", not the Trakt event time. The guard compares the INCOMING Trakt timestamp vs the EXISTING local one (correct for preventing rollback); on the next sync the same Trakt entry (older than the now-stamped local) is skipped (idempotent). I did NOT change `updateProgress`'s signature (out of scope + shared with the player's progress path). **Existing tests:** none asserted the old force-100 behavior — `TraktHistorySyncTest` only tests `TraktSettings` flags (its own docblock admits it does not test the sync), and `TraktApiTest` tests `getWatchedHistory` fetch/endpoint only. So NO existing test expectation needed updating. **Verification (verbatim):** - `phpstan analyse -c phpstan.neon.dist --level=9 --memory-limit=512M --no-progress` (full src) → **[OK] No errors**. - `phpcs --standard=PSR12 src/Plugins/Scrobbler/Trakt/` → **0 ERRORS** (only pre-existing + a few new line-length WARNINGS, allowed). - `phpunit --filter Trakt --no-coverage` → **OK (63 tests, 131 assertions)**. **Notes for 3.6d (pagination) / 3.6e (tests) — NOT implemented:** - 3.6d: `reconcileWatchedHistory` still calls `getWatchedHistory($user,1,100,$token)` — the page loop (honor `X-Pagination-Page-Count`, `\Co\sleep` between pages) goes here. `getPlaybackProgress` is NOT paginated by Trakt, so leave it single-shot. - 3.6e: reconciliation is now testable via a mocked `TraktApi` (feed `getWatchedHistory` + `getPlaybackProgress` fixtures) + a mocked `WatchHistory`/`Connection`. Use the `_resolved_media_item_id` test seam in `findMediaItemId` to bypass DB id resolution. Key cases to cover: watched→completed; playback→resume position (position = dur*pct/100, status PAUSED); last-write-wins skip (local `last_watched_at` newer than Trakt ts); don't-downgrade-completed skip; no-duration skip; `getPlaybackProgress` 429/backoff. `MockHttpClient` already records `lastMethod`/`lastUrl` for an endpoint assertion (`/sync/playback`). Pre-existing observation (affects getWatchedHistory too, not fixed here): the Trakt client sends no `trakt-api-key`/`trakt-api-version` headers — out of 3.6c scope. ## Implementer — SV-3.6b (de-block Trakt HTTP path) — 2026-07-13 — ✅ DONE (commit `51e6a16e`, pushed origin/master) **Scope (exactly this, nothing else):** de-block the Trakt PULL-sync HTTP path so it can later be driven by a resident-worker Timer (3.6a) without stalling the event loop. Did NOT touch the Timer wiring (3.6a), resume positions (3.6c), pagination (3.6d), or tests (3.6e). **Files changed (2):** - `src/Plugins/Scrobbler/Trakt/HttpClient.php` — rewrote the private `request()` transport. Was unconditional synchronous cURL; now selects transport the SAME way the donors do: `EventLoopTls::requiresBlockingCurl($url) || !WorkerContext::isEventLoopRunning() || !WorkerContext::inCoroutine()` → blocking cURL, else the async `workerman/http-client` cooperative-wait. Added lazy `getAsyncClient()` (`new Client(['timeout'=>$this->timeout])`), `requestAsync()` (Channel-based: success/error callbacks push a `Swoole\Coroutine\Channel(1)`, `pop((float)$timeout)` yields the coroutine), and `requestCurl()` (fallback; now captures response headers via `CURLOPT_HEADERFUNCTION` into an assoc array and returns a `Workerman\Http\Response` so `Retry-After` on 429 survives). Status handling (401→`TraktAuthenticationException`, 429→`TraktRateLimitException` with `Retry-After` via PSR-7 `getHeaderLine()`, ≥400→`TraktApiException`, JSON decode) is now transport-agnostic and behaviourally identical. Public `get()/post()` signatures + the `HttpClientInterface` contract UNCHANGED; ctor still `__construct(int $timeout = 15)` so the `new HttpClient()` call sites (`TraktPlugin.php:446`, `TraktOAuthController.php`) are unaffected. Dropped the dead `CURLOPT_CUSTOMREQUEST` branch (Trakt only issues GET/POST — the original had no such branch) and the unused `NullLogger` import. - `src/Plugins/Scrobbler/Trakt/TraktApi.php` — `getWatchedHistory()` 429-backoff loop (was `usleep((int)($delayMs*1_000))` at ~:436): now `\Co\sleep($delayMs/1_000)` under `function_exists('\Co\sleep')`, `usleep` fallback otherwise — mirrors the existing idiom at `refreshAfterAuthFailure()` (:189-193/:222-226). This is the sole remaining blocking sleep on the pull path. **Donor pattern mirrored:** `Phlix\Media\Metadata\MetadataHttpClient` (Channel + success/error callbacks + `requestCurl` returning a PSR-7 `Workerman\Http\Response`) and `Phlix\Hub\HttpClient` (the `EventLoopTls` + `WorkerContext::isEventLoopRunning()/inCoroutine()` transport gate). Verified via `vendor/workerman/http-client/src/Client.php` that non-2xx (401/429/4xx/5xx) responses arrive through the `success` callback (only 3xx are auto-followed; connection/timeout errors hit `error`), so Trakt's status-based branching is preserved. **Non-coroutine fallback preserved:** `WorkerContext::inCoroutine()` returns false when swoole is absent (plain CLI/PHPUnit) and `isEventLoopRunning()` false outside a running worker, so both the transport selection AND `\Co\sleep` gate fall back to blocking cURL / `usleep`. Unit tests use a `MockHttpClient` (implements `HttpClientInterface`) and never touch the real client — all green. **Verification (verbatim summary lines):** - `phpstan analyse -c phpstan.neon.dist --level=9` (both changed files) → **[OK] No errors**. - `phpcs --standard=PSR12 src/Plugins/Scrobbler/Trakt/` → **0 ERRORS** (only pre-existing line-length WARNINGS in TraktPlugin/TraktApi/TraktHistorySync; `HttpClient.php` clean). - `phpunit --filter Trakt --no-coverage` → **OK (63 tests, 131 assertions)**. **Notes for adjacent sub-steps (NOT implemented here):** - **3.6a (Timer wiring):** the path is now event-loop-safe to call from a coroutine timer — the async client yields, the backoff yields. Only residual blocking I/O on the pull path is the `flock()`-based cross-process refresh mutex in `refreshAfterAuthFailure()`, which already uses `LOCK_NB` + `\Co\sleep` polling (bounded ~2s) — so it also yields. Put the `Timer::add` in `start.php` `onWorkerStart`, worker-0-gated, NOT `index.php`. - **3.6c/3.6d:** untouched — `syncTraktToPhlix` still force-writes `STATUS_COMPLETED` and `getWatchedHistory` is still called with hardcoded `page=1,limit=100`. When 3.6d adds a page loop, the between-page backoff should reuse the same `\Co\sleep`-under-cid idiom now in `getWatchedHistory`. - **EventLoopTls caveat:** Trakt is always `https://api.trakt.tv`, so under the Swoole event loop `requiresBlockingCurl()` returns true today → the blocking-cURL branch is taken in prod (curl is unhooked, runs as a plain blocking call — the accepted repo-wide tradeoff for low-frequency control-plane clients, same as Metadata/Hub). The async branch activates automatically if/when the upstream Swoole-TLS stall is fixed (EventLoopTls flips to false). The genuine de-block that matters right now on the loop is the sleep conversion; the transport now matches the rest of the repo instead of being an unconditional blocking outlier. ## Implementer — SV-3.6a (wire worker-0-gated periodic Trakt pull-sync Timer) — 2026-07-13 **Scope (exactly this, nothing else):** arm the periodic Trakt→Phlix PULL timer in `start.php` and resolve the profileId inconsistency. Did NOT touch reconciliation/resume/pagination inside `syncTraktToPhlix` (3.6c/3.6d), the HTTP path (3.6b, already landed), or tests (3.6e). **Files changed (2):** - `start.php` — added a worker-0-gated (`(int) $w->id === 0`) block in the HTTP worker's `onWorkerStart`, placed right after the SV-3.1c DVR scheduler block and mirroring its exact idiom (worker-0 gate + arm-time try/catch + a `Workerman\Timer::add` whose callback is try/catch-wrapped and relies on the Swoole event adapter's `Coroutine::create`/safeCall wrap — NO manual `Coroutine::create`, same as the DVR scheduler / metrics-flush timers). At arm time it resolves `PluginLoader` from the container, reads the installed `phlix-plugin-trakt` settings via `getInstalled()`, and arms `Timer::add($syncIntervalMinutes * 60, …)` ONLY when `installed.enabled && settings.sync_enabled && interval > 0` (respects a disabled config — logs a debug line and does not arm otherwise; `PluginNotFoundException` → debug "not installed", any other throwable → logged error, never crashes the worker). Each tick resolves a FRESH entry instance via `PluginLoader::getEntryInstance()` (re-reads DB-persisted settings so runtime enable/token changes are picked up) and calls the new `TraktPlugin::syncHistoryFromTrakt($container)`. Logs via `LogChannels::PLUGINS`. - `src/Plugins/Scrobbler/Trakt/TraktPlugin.php` — added: - `public const DEFAULT_PROFILE_ID = 'default'` (single source of truth for the scrobbler profile; updated the push path `syncToTrakt()`'s previously-hardcoded `getForMediaItem('default', …)` at old line 501 to use it). Left `TraktHistorySync.php:174`'s `'default'` literal untouched (inside `syncPhlixToTrakt`, out of 3.6a scope — noted below). - `public function syncHistoryFromTrakt(ContainerInterface $container, string $profileId = self::DEFAULT_PROFILE_ID): int` — thin wiring entry point mirroring the private push wrapper `syncToTrakt()`: self-wires runtime collaborators via `onEnable($container)` when missing (the resident server never calls `bootstrapEnabled()` — see finding — and `getEntryInstance()` applies settings but not `onEnable()`), gates on `isConfigured() && settings->syncEnabled`, then builds a `TraktHistorySync` from current settings and delegates to `syncTraktToPhlix($profileId)`. Adds NO reconciliation logic. **profileId decision — SINGLE-profile → use `'default'`.** Trakt is one-account-per-server today: a single `TraktSettings::$username`, no per-Phlix-profile Trakt mapping, and the push path already hardcodes `'default'` (`TraktPlugin.php:501`, `TraktHistorySync.php:174`). The pull now mirrors that via the new `DEFAULT_PROFILE_ID` const. Multi-profile (a Trakt account per Phlix profile, one sync per profile) is documented in the const + method docblocks as a future extension (callers would loop over configured profiles). No multi-profile config exists in the code — did NOT invent one. **TraktSettings interval field:** `syncIntervalMinutes` (int, MINUTES, default 30, from `sync_interval_minutes` in the plugin `settings_json`). Converted minutes→seconds (`* 60`) for `Timer::add`. Disabled-config behavior: timer is NOT armed when the plugin is disabled, `sync_enabled` is false, or the interval ≤ 0. **DI binding added: NONE.** `TraktHistorySync` and its deps (`TraktApi`, `TraktSettings`) are intentionally NOT registered in the container — a static PHP-DI singleton binding would freeze the plugin's settings (OAuth tokens, username, interval, enable flag) at container-build time, which is wrong because those are dynamic (re-auth / enable toggles persist to the `plugins.settings_json` column at runtime). The correct resolution path is the plugin itself: `PluginLoader` (already container-registered) → `getEntryInstance()` re-reads the live persisted settings each tick, and the plugin builds a fresh `TraktHistorySync` per sync (exactly as the push path already does on-demand). **Verification (verbatim):** - `php -l start.php` → `No syntax errors detected in start.php`; `php -l …/TraktPlugin.php` → clean. - `phpstan analyse -c phpstan.neon.dist --level=9 --memory-limit=512M --no-progress` (full `src`) → `[OK] No errors`. (`start.php` is outside phpstan's `paths: [src]`, so it is `php -l`-only; correctness reasoned against the neighboring DVR scheduler / metrics timers it mirrors.) - `phpcs --standard=PSR12 start.php` → 0 errors. `phpcs …/TraktPlugin.php` → 0 ERRORS, 1 pre-existing line-length WARNING at line 470 (inside `ensureFreshToken`, not mine — noted already in SV-3.6b). - `phpunit --filter Trakt --no-coverage` → **OK (63 tests, 131 assertions)**. - `phpunit PluginLoaderTest + ContainerFactoryTest + HttpHandlerWiringTest` → **OK (69 tests)**. **Findings noted (NOT fixed here — out of 3.6a scope):** - **`PluginLoader::bootstrapEnabled()` is never called in any production boot path** (`start.php`, `public/index.php`, `Application.php`, `ContainerFactory` — grep confirms only tests call it). So enabled plugins are NOT re-attached after a restart, and `enable()` only ever runs in the single HTTP worker that served an admin toggle. This is why 3.6a resolves the plugin fresh + self-wires via `onEnable()` rather than trusting a live enabled instance. Broader plugin prod-inertness gap — likely worth its own step; affects PUSH scrobbling across restarts too. - **Token-refresh is not persisted:** `TraktPlugin::setAccessToken/setRefreshToken` mutate only in-memory settings; refreshed tokens are never written back to `plugins.settings_json`. The PULL path never triggers a refresh (`syncTraktToPhlix` catches the 401 `TraktApiException` and returns 0), so this doesn't break the pull, but an expired access token silently no-ops the sync until re-auth. Pre-existing; out of scope. - **3.6c (resume positions):** `syncTraktToPhlix` (`TraktHistorySync.php:93-137`) still force-writes `STATUS_COMPLETED` (full duration ticks) and parses `watched_at` at :121 only to log it — the parsed timestamp is discarded rather than used for last-write-wins. Untouched. - **3.6d (pagination):** `getWatchedHistory` is still called with hardcoded `page=1, limit=100` (`TraktHistorySync.php:80-85`); no page loop honoring `X-Pagination-Page-Count`. Untouched. - Trakt→local mapping depends on `media_items.metadata_json` carrying `{tmdb_id,tvdb_id,imdb_id}` (`findMediaItemIdByExternalId` JSON_EXTRACTs `$._id`). Did NOT audit the scanner's population of those here (mapping is inside the already-built sync, not wiring). ## Reviewer (cumulative) — 2026-07-13 Cumulative integration review of SV-3.6 (Trakt history PULL sync) across the 4 commits `51e6a16e` (3.6b) · `c7a0094c` (3.6a) · `d7ca10c1` (3.6c) · `21b04510` (3.6d), base `edda2ce1`. Scope confined to `src/Plugins/Scrobbler/Trakt/**` + `start.php` — no out-of-scope files touched. End-to-end wiring traced: Timer (start.php:288-291, worker-0-gated, repeating, try/catch, container captured as a per-worker local) → `TraktPlugin::syncHistoryFromTrakt` → `getEntryInstance`+`onEnable` self-wire (verified independent of the never-called `bootstrapEnabled`) → `syncTraktToPhlix` → `getWatchedHistory`/`getPlaybackProgress` → `HttpClient::requestWithHeaders` → reconcile → `WatchHistory::updateProgress`. Transport/backoff/coroutine rules, exception hierarchy (all three Trakt exceptions extend `TraktApiException`, so the reconcilers' single catch covers 401/429/4xx), return-shape threading (`getWatchedHistory` `{items,pageCount}` — only caller is `TraktHistorySync`; `getWithHeaders` implemented by both the real client and the test `MockHttpClient`; `Phlix\Hub\HttpClient` implements a *different* interface, unaffected), pagination termination (header-bound + short-page fallback + `MAX_HISTORY_PAGES` cap + per-page-failure preserves prior writes), last-write-wins / never-downgrade-completed / no-duration-skip guards, and TZ handling in `traktSupersedes` were all checked and are correct. No token leakage in logs; no `exit`/`die`; no blocking `sleep` on the loop. ### Findings 1. **[HIGH — AC-blocking]** `TraktApi.php:410-413` (`getWatchedHistory` headers) & `TraktApi.php:528-531` (`getPlaybackProgress` headers); root cause at `HttpClient.php:143-147` (base header assembly). **CONFIRMED**: the Trakt client sends NO `trakt-api-key` (client id) and NO `trakt-api-version: 2` header on any request. `requestWithHeaders()` seeds only `User-Agent`/`Content-Type`/`Accept` and merges the caller's headers; the two API methods add only `Authorization: Bearer`. A repo-wide grep for `trakt-api-key`/`trakt-api-version` returns nothing. Trakt MANDATES both headers on every API call (v2), so `/users/{u}/watched` and `/sync/playback` return 403 → both reconcilers catch, log, and contribute 0 → **the sync remains a no-op against live Trakt, so the AC ("watched history is reflected locally after a sync run") is NOT met** regardless of the (correct) wiring/pagination/resume logic. The `clientId` is already on `TraktApi`'s ctor (`$this->clientId`). Fix (in-scope per §0.1): inject `trakt-api-key: ` + `trakt-api-version: 2` into the request headers for the API (non-OAuth) calls — a shared private header-builder applied to `getWatchedHistory`/`getPlaybackProgress` (and, for completeness, `scrobble`/`addToHistory`). The `/oauth/token` calls (`exchangeCode`/`refreshAccessToken`) do NOT need them (client_id is in the body), so scope the builder to the API surface. 2. **[MEDIUM — test gap]** The reconciliation core — `TraktHistorySync::syncTraktToPhlix` / `reconcileWatchedHistory` (the page loop) / `reconcilePlaybackProgress` (resume positions) — has ZERO test coverage. `TraktApiTest` covers `getWatchedHistory` shape/endpoint only; `TraktHistorySyncTest` tests settings flags only (its own docblock admits it). The multi-page loop, last-write-wins skip, don't-downgrade-completed skip, no-duration skip, and the resume-position math are all unexercised. A `syncTraktToPhlix` integration test asserting the OUTGOING request headers would have caught finding #1. 3.6e is the designated home, but the feature currently ships its AC-critical logic untested — recommend 3.6e land with (and before closing) this feature, including a header assertion. 3. **[LOW]** `TraktHistorySync.php:266-273` — the completed path passes `extractDurationTicks($itemMap)` as BOTH position and duration to `updateProgress(..., STATUS_COMPLETED)`. Because `/watched` omits `runtime` (no `extended=full`), `extractDurationTicks` returns 0 (see #note), so this writes `duration_ticks = 0`, **clobbering a previously-known `duration_ticks`** when upgrading an existing in-progress row to completed (`updateProgress` uses `COALESCE(?, duration_ticks)`, and 0 is not NULL, so it overwrites). Prefer passing `null` for the duration on the completed path (matching `WatchHistory::markCompleted`, which preserves the stored duration and yields the same status='completed'/progress=0 "watched" shape the app already uses), or resolve a local duration via the existing `resolvePlaybackDurationTicks`. *Note:* `extractDurationTicks` (`:762-782`) also carries a latent minutes-as-seconds bug (Trakt `runtime` is MINUTES; treated as seconds) — dormant today because `runtime` is absent, but it would corrupt completed-row durations the moment `extended=full` is added. Documented already by the 3.6c implementer; not AC-blocking (resume positions use `resolvePlaybackDurationTicks`, not this method). 4. **[INFO]** Arm/tick gate asymmetry (`start.php:~283` vs `TraktPlugin::isConfigured`). The timer arms on the `plugins.enabled` column + `sync_enabled` + interval>0, but each tick's `isConfigured()` additionally requires the manifest master setting `enabled` (persisted in `settings_json`, `plugin.json` default **false**). This dual gate is by design (a "Master on/off for Trakt" switch, default off) and is NOT a correctness bug — but it means a merely catalog-enabled + authorized ("connected") Trakt account still syncs nothing until the operator turns the master switch on, and in that state the resident timer arms and no-ops every interval. Consider also gating the arm on the master `enabled` setting (avoid a perpetually-no-op timer) and/or documenting the two-switch requirement so "I connected Trakt but nothing syncs" is expected, not a bug report. **Verdict: 1 HIGH (AC-blocking) + 1 MEDIUM + 1 LOW + 1 INFO. Loop back to the Fixer for #1 (and #2/#3).** ## Fixer — SV-3.6 cumulative-review findings #1/#3/#4 — 2026-07-13 Fixed findings #1 (HIGH), #3 (LOW), #4 (INFO). Finding #2 (reconciliation test coverage) is left for the later Test agent (3.6e) — I only kept the existing Trakt suite green, added no new test files. **Files changed (4):** `src/Plugins/Scrobbler/Trakt/TraktApi.php`, `src/Plugins/Scrobbler/Trakt/TraktHistorySync.php`, `start.php`, this worklog. ### Finding #1 — mandatory Trakt API headers (HIGH, AC-blocking) - Added a single shared private builder `TraktApi::apiHeaders(?string $bearer = null): array` — the ONE source of `trakt-api-key: ` + `trakt-api-version: 2`, plus an optional `Authorization: Bearer ` when a non-empty access token is supplied. - Routed EVERY data-API request-issuing method in the class through it: `scrobble()` (used by `scrobbleStart/Pause/Stop`), `getWatchedHistory()`, `getPlaybackProgress()`, and `addToHistory()`. These replace the old `['Authorization' => 'Bearer …']`-only / conditional-Authorization header arrays, so no call site can omit the mandatory pair. (No `/search` or other data-API calls exist in this class — verified by grepping `$this->http->` : lines 104/140 are the two `/oauth/token` posts, the other four are the data-API sites now routed.) - **/oauth EXCLUDED:** `exchangeCode()` and `refreshAccessToken()` (the only `/oauth/token` callers; `refreshAfterAuthFailure()` delegates to the latter) post with client_id/secret in the BODY and are left untouched — they do NOT go through `apiHeaders()`, matching Trakt's documented OAuth contract. Token-refresh path confirmed still working (its `TraktApiTest` cases pass). - **clientId sourcing / can-it-be-empty:** traced `TraktPlugin::initApi()` (:511-526) — it reads `config/scrobblers/trakt.php` `client_id`/`client_secret` and **only constructs `TraktApi` when BOTH are non-empty**; otherwise `$this->api` stays null → `TraktPlugin::isConfigured()` (:533-538) is false → `syncHistoryFromTrakt()` returns 0 (skips). So in the resident server the ctor `clientId` is guaranteed non-empty whenever a request is issued — an empty key is structurally unreachable and the sync already fails-fast/skips at the plugin layer. As defense-in-depth I still guard inside `apiHeaders()`: if `clientId === ''` it logs `"Trakt client_id not configured; skipping API request"` and throws `TraktApiException` (so we NEVER send an empty `trakt-api-key`; the reconcilers' existing `TraktApiException` catch logs it and contributes 0). All existing tests construct with a non-empty `test-client-id`, so none hits this branch. ### Finding #3 — duration_ticks=0 clobber (LOW) - `TraktHistorySync::reconcileWatchedPage()` completed path: now computes `$knownDuration = $durationTicks > 0 ? $durationTicks : null` and passes `$knownDuration` as the duration (and `$knownDuration ?? 0` as position). When `/watched` omits `runtime` (`extractDurationTicks` → 0), we now pass `null`, so `updateProgress`'s `duration_ticks = COALESCE(?, duration_ticks)` PRESERVES the previously-known duration on an in-progress→completed upgrade (a `0` would have satisfied COALESCE as a real value and overwritten it). This matches `WatchHistory::markCompleted()` (position 0, duration null → status=completed, progress=0). Confirmed against `WatchHistory::updateProgress` (:335-421): the UPDATE binds the nullable `$durationTicks` into `COALESCE(?, duration_ticks)` → NULL is the "don't change" sentinel. A present `runtime` still uses it as both position and duration (100% shape) unchanged. ### Finding #4 — arm/tick gate asymmetry (INFO→align) - `start.php` now derives `$traktMasterEnabled = ($installedTrakt->settings['enabled'] ?? false) === true` (the manifest master switch, `settings_json.enabled`, default false — the SAME flag `TraktPlugin::configure()` reads into `$this->enabled` and `isConfigured()` requires each tick) and ANDs it into the arm condition alongside `$installedTrakt->enabled` (catalog column), `syncEnabled`, and `interval > 0`. So the timer only arms when a tick would actually do work; a catalog-enabled + connected account with the master switch OFF no longer arms a perpetually-no-op timer. Added the master flag to the "not armed" debug log. Left a brief comment noting the pre-existing boot-time limitation (arming runs once at `onWorkerStart`, so toggling the master ON after boot won't arm until restart) — NOT fixed, as instructed. ### Verification (verbatim) - `php -l start.php` → `No syntax errors detected in start.php`. - `phpstan analyse -c phpstan.neon.dist --level=9 --memory-limit=512M --no-progress` (full `src`) → `[OK] No errors`. (Also ran scoped to `src/Plugins/Scrobbler/Trakt/` → `[OK] No errors`.) - `phpcs --standard=PSR12 src/Plugins/Scrobbler/Trakt/` → **0 ERRORS** (4 pre-existing line-length WARNINGs only: TraktApi:408/722, TraktPlugin:470, TraktHistorySync:420 — none introduced here). - `phpunit --filter Trakt --no-coverage` → **OK (64 tests, 133 assertions)**. ## Reviewer (cumulative, confirming re-review of fix `23fbc4c5`) — 2026-07-13 Focused re-review of the Fixer's `23fbc4c5` against findings #1/#3/#4. READ-ONLY; verified via `git show 23fbc4c5` + reading the shipped code. - **#1 (HIGH) — RESOLVED.** New shared `TraktApi::apiHeaders(?string $bearer = null)` emits `trakt-api-key: ` + `trakt-api-version: 2` (+ optional Bearer). Grep of `$this->http->` in `TraktApi.php` confirms exactly two `/oauth/token` posts (104/140, correctly NOT routed) and all four data-API sites — `scrobble()` (363), `getWatchedHistory()` (410), `getPlaybackProgress()` (525), `addToHistory()` (631) — now go through `apiHeaders()`. `HttpClient::requestWithHeaders` merges these over its base headers, so both mandatory headers are on every data-API request. No data-API call site bypasses the builder. - **Regression (push path) — none.** For `scrobble`/`addToHistory` the change is strictly additive: the previous `['Authorization' => 'Bearer '.$token]` becomes `{trakt-api-key, trakt-api-version, Authorization: Bearer }`. No header dropped. The only behavior delta is that an EMPTY access token now omits `Authorization` instead of sending a meaningless `Bearer ` — an improvement, and such a call never authenticated anyway (not a working path). - **Empty-clientId throw — safe.** `apiHeaders()` throws `TraktApiException` on `clientId === ''`. Unreachable in prod (`TraktPlugin::initApi()` only builds the client when client_id+secret are both non-empty; the OAuth controller constructs `TraktApi` only for the excluded `/oauth` path). If it ever fired, every call site is covered by an existing `TraktApiException` catch: `getWatchedHistory`/ `getPlaybackProgress` are invoked inside the reconcilers' try/catch; `scrobble` re-throws into `onPlaybackStarted/Stopped`'s catch; `addToHistory` propagates to `syncPhlixToTrakt`'s catch — and the timer callback has a final `\Throwable` backstop. No uncaught escape can kill the worker or the timer. - **#4 /oauth exclusion + token refresh — correct.** `exchangeCode`/`refreshAccessToken` (and `refreshAfterAuthFailure`, which delegates to the latter) still post client_id/secret in the body with no api-key header, per Trakt's OAuth contract. Unchanged. - **#3 (LOW) — RESOLVED.** `reconcileWatchedPage` now derives `$knownDuration = $durationTicks > 0 ? $durationTicks : null` and passes `$knownDuration ?? 0` (position) / `$knownDuration` (duration). An unknown duration → `null` → `updateProgress`'s `COALESCE(?, duration_ticks)` preserves the stored duration (matching `markCompleted`); a present runtime still yields the 100% shape. No clobber. - **#4 (INFO) — RESOLVED.** `start.php` arm condition now ANDs `$traktMasterEnabled = ($installedTrakt->settings['enabled'] ?? false) === true` — the same master flag each tick's `isConfigured()` requires — alongside the catalog column, sync_enabled, and interval>0, so a master-off account no longer arms a perpetually-no-op timer. Debug log updated. The pre-existing "arm once at onWorkerStart" limitation is documented, correctly left unfixed. - **Cleanliness:** diff is type-sound on inspection (`apiHeaders` `array`; `int|null` duration matches `updateProgress`'s `?int`; bool arm gate). Fixer reports phpstan L9 [OK], phpcs 0 errors, phpunit --filter Trakt 64/64. - **#2 (MEDIUM, test gap)** correctly deferred to the Test step (3.6e) — no new tests added here. NO FINDINGS. ## TestEngineer — SV-3.6e (tests for Trakt PULL sync) — 2026-07-13 Built out the reconciliation / header / pagination / backoff tests the opencode run skipped and the cumulative review flagged as the AC-critical gap (finding #2). Tested the FINAL shipped shape at HEAD `23fbc4c5` (review = NO FINDINGS). **41 new Trakt tests** added (suite 64 → 105); all green. **Files (absolute):** - `tests/Unit/Plugins/Scrobbler/Trakt/TraktApiTest.php` — +9 tests (headers + 429 backoff + type-filter); extended `MockHttpClient` to throw queued `\Throwable`s so the retry loops are exercisable. - `tests/Unit/Plugins/Scrobbler/Trakt/MockHttpClient.php` — **NEW**: extracted the `MockHttpClient` double out of `TraktApiTest.php` into its own PSR-4-autoloaded file (fixes the pre-existing phpcs "each class in a file by itself" error in the file I edited + makes it robustly autoloadable, no longer reliant on `TraktApiTest.php` load order). It already captured `lastHeaders` (req #1 needs no new capture); the only extension is the throwable queue for 429 simulation. - `tests/Unit/Plugins/Scrobbler/Trakt/TraktHistorySyncReconcileTest.php` — **NEW**: 29 reconciliation tests (mocked `TraktApi` + `WatchHistory` + `Connection`; deterministic id via the `_resolved_media_item_id` seam, one test using the real JSON_EXTRACT lookup path). - `tests/Unit/Plugins/Scrobbler/Trakt/HttpClientTest.php` — **NEW**: 3 non-network guard tests (empty-URL rejection on get/getWithHeaders/post). The real transport is network I/O and — matching the repo's own idiom for the sibling de-blocked clients (`Hub\HttpClient`, `MetadataHttpClient`, whose tests do NOT spin a live server) — is exercised via `MockHttpClient` at the caller level, not directly. **9 required-coverage items → tests:** 1. Outgoing headers (regression guard for HIGH finding #1): `testGetWatchedHistorySendsMandatoryApiHeaders`, `testGetPlaybackProgressSendsMandatoryApiHeaders`, `testApiHeadersOmitAuthorizationWhenTokenEmpty`, `testApiCallThrowsWhenClientIdNotConfigured`. Mutation reasoning documented in the docblocks: dropping `trakt-api-key`/`trakt-api-version` from `apiHeaders()` (the pre-fix shape) flips the `assertSame`s red. 2. Reconcile watched→completed: `testWatchedHistoryReconcilesToCompletedWithNullDuration`, `testWatchedHistoryWithRuntimeUsesFullDuration`, `testMediaItemResolvedViaDatabaseExternalId`, `testMediaItemResolvedViaSecondIdTypeAfterMiss`. 3. Reconcile playback/resume (pos ≈ dur·pct/100, PAUSED, not 100%): `testPlaybackProgressWritesResumePosition`, `testPlaybackUsesScannedMetadataDuration`, `testResumeWrittenWhenLocalTimestampUnparseable`. 4. Last-write-wins skip (older Trakt event): `testOlderTraktWatchIsSkipped`, `testPlaybackSkipsNonArrayUnresolvedAndOlderEntries`. 5. Never-downgrade-completed: `testCompletedItemNotDowngradedByPlayback`, `testWatchedSkippedWhenLocallyAtCompletionThreshold`. 6. No-known-duration skip: `testPlaybackSkippedWhenNoDurationKnown`, `testResumeSkippedWhenNoLocalTimestampAndMetadataMiss`, `testResumeSkippedWhenMetadataRowMalformed`. 7. Duration COALESCE null (assert `null`, not `0`, bound on completed path): asserted via `$this->identicalTo(null)` (strict — `0 !== null`) in `testWatchedHistoryReconcilesToCompletedWithNullDuration`, `testMediaItemResolvedViaDatabaseExternalId`, `testPlaybackFetchFailureIsIsolated`. 8. Pagination (pages 2..N, short-page/reported-count/cap termination, per-page-failure preserves writes): `testPaginationFetchesAllReportedPages`, `testPaginationStopsAtReportedPageCountEvenIfPagesFull`, `testReportedPageCountAboveCapIsTruncated`, `testPageFetchFailurePreservesEarlierWrites`. 9. Rate-limit 429 backoff (retry happens → succeeds; non-429 not retried): `testGetWatchedHistoryRetriesAfterRateLimitThenSucceeds`, `testGetPlaybackProgressRetriesAfterRateLimitThenSucceeds`, `testGetWatchedHistoryDoesNotRetryNonRateLimitError`, `testGetPlaybackProgressDoesNotRetryNonRateLimitError`. **Verification (verbatim):** - `./vendor/bin/phpunit --filter Trakt --no-coverage` → **OK (105 tests, 230 assertions)** (was 64/133). - `./vendor/bin/phpstan analyse -c phpstan.neon.dist --level=9 --memory-limit=512M --no-progress` (src) → **[OK] No errors**. phpstan L9 on the 4 test files explicitly → **[OK] No errors** (tests are outside `phpstan.neon.dist paths: [src]`, so run explicitly). - `./vendor/bin/phpcs --standard=PSR12 tests/Unit/Plugins/Scrobbler/Trakt/{TraktApiTest,TraktHistorySyncReconcileTest,HttpClientTest,MockHttpClient}.php` → **0 errors, 0 warnings** on all four of my files. (The full-dir command still reports PRE-EXISTING `test_snake_case` method-name errors in `TraktOAuthStateStoreTest.php` (5) and `DbTraktOAuthStateStoreTest.php` (17) — untouched OAuth-state-store files, unrelated to SV-3.6e, present at HEAD before this step; left as-is to avoid unrelated churn. `src/Plugins/Scrobbler/Trakt/` = 0 errors, only the pre-existing line-length warnings.) **Coverage of the changed files (pcov, filtered to `src/Plugins/Scrobbler/Trakt`):** - `TraktHistorySync.php`: **97.9%** of the SV-3.6-changed method lines (235/240); whole-file 84.9% (the rest is the untouched push path `syncPhlixToTrakt`/`buildMediaItem`). - `TraktApi.php`: **89.2%** of the changed method lines (83/93) — **95.4%** excluding 6 genuinely unreachable post-loop defensive `return`/`throw` guards; whole-file 61.6% (rest = untouched OAuth/scrobble/addToHistory push path). - `HttpClient.php`: whole-file 7.4% — transport is live network I/O, per-idiom not unit-tested (see above); the 3 guard tests cover the reachable non-network branch. **Genuinely-untestable branches in this sandbox (with reason):** - `TraktApi::getWatchedHistory`:452 / `getPlaybackProgress`:562 and `TraktHistorySync::sleepBetweenPages`:308 — the `\Co\sleep(...)` coroutine branch. `function_exists('\Co\sleep')` is **false** in the PHPUnit process (Swoole loaded but no coroutine/short-name), so only the `usleep` fallback runs; the coroutine branch is only reachable inside a real Swoole coroutine (the resident-worker Timer), which the tests deliberately do not require. - `TraktApi::getWatchedHistory`:458 / `getPlaybackProgress`:568 — the give-up `throw $e` after 5 exhausted 429 retries. Each requires ~31–62 s of real backoff sleep (1+2+4+8+16 s + jitter, constants are private), prohibitive for a unit test; the retry-then-succeed path (req #9) proves the loop mechanics. - `TraktHistorySync::reconcileWatchedHistory`:205-208 — the `page >= MAX_HISTORY_PAGES(=200)` warn block; reaching it needs 200 FULL 100-item pages + 199×250 ms inter-page sleeps (~50 s+), prohibitive. The reported-page-count / short-page / cap-truncation termination branches ARE covered (`testPaginationStopsAtReportedPageCountEvenIfPagesFull`, `testReportedPageCountAboveCapIsTruncated`). - 6 post-loop defensive `return`/`throw` lines in the two API methods are unreachable dead code (the `for` loop always returns on success or throws on the last attempt). No production bug found — the shipped SV-3.6 shape behaves correctly against every case tested. GREEN. ## Implementer — SV-4.13-finish (remove dead `buildTranscodeCommandWithProfile` + fix stale whole-file docrefs) — 2026-07-13 Finishes the last deferred piece of SV-4.13. The main whole-file builders (`buildTranscodeCommand`/ `buildHlsCommand`/`buildHwaccelCommand`) were already removed in `c8f94c04` (checklist line 104); `buildTranscodeCommandWithProfile` was left behind at the time because SV-1.6 was mid-flight. §6/R1 user-approved its removal. **STEP 1 — zero-caller re-confirmation (grep, HEAD `0cf506f0`):** - Definition: `src/Media/Transcoding/FfmpegRunner.php:1430` (`public function buildTranscodeCommandWithProfile(`). - ONE test-side docblock `{@see}`: `tests/Unit/Media/Transcoding/FfmpegRunnerSubtitleBurnInTest.php:19`. - Worklog prose only (documentation, not code). - **ZERO** method-call sites (`->buildTranscodeCommandWithProfile(`) anywhere in `src/`, `tests/`, `start.php`, `public/index.php`, `config/`, `bin/`, `scripts/`. Safe to remove. **STEP 2 — removal:** - Deleted `buildTranscodeCommandWithProfile` in full (docblock + method body, old lines 1412–1471) from `FfmpegRunner.php`. - Removed the now-orphaned `use ...\Hwaccel\HwaccelCommandBuilder;` import (old line 15) — its only code user was the deleted method's body (`new HwaccelCommandBuilder(...)`). No remaining code references it (verified by grep + phpstan L9 = 0 errors). - ALSO removed the `use ...\Hwaccel\Profiles\HwaccelEncoderProfileInterface;` import (old line 17) — it was orphaned by the same removal (its only code use was the deleted method's `$profile` parameter type; the one surviving reference at line ~2040 is a fully-qualified `{@see \Phlix\...\HwaccelEncoderProfileInterface::getInputDeviceArgs()}` doc, which does not consume the import). Neither phpcs (PSR12, no unused-use sniff) nor phpstan flags unused imports, so this is a correctness cleanup of code newly-orphaned by my own edit, not a scope creep. phpstan L9 confirms nothing dangles. - Did NOT touch any private helper (`paramString`/`paramInt`/`browserSafeVideoFlags` remain shared with the live builders), nor `HwaccelCommandBuilder` the class, `HwaccelProfileFactory`, `SubtitleBurner`, or `StreamManager::setSubtitleBurnIn`. **STEP 3 — docref fixes:** - REQUIRED (breaking `@see`): `FfmpegRunnerSubtitleBurnInTest.php` class docblock — dropped the dangling `{@see FfmpegRunner::buildTranscodeCommandWithProfile()}` and the "HwaccelCommandBuilder is only used by the zero-caller ..." clause; rewrote the paragraph to describe what the tests actually exercise (the LIVE `buildSegmentCommand`/`buildHwaccelSegmentCommand` per-segment subtitle burn-in path, keeping the live `{@see SubtitleBurner}` reference). Test METHODS unchanged (still green). - Prose "whole-file path" cleanups (non-breaking): - `FfmpegRunner.php` (SV-1.6 ordering comment, old ~:1711): dropped ", same ordering HwaccelCommandBuilder uses for the whole-file path"; kept the accurate "before scale / before hwupload" ordering rationale. - `FfmpegRunner.php` (`buildHwaccelInputFlags` docblock, old ~:2103): reworded "used by {@see HwaccelCommandBuilder} for the whole-file transcode path, so the two paths share ONE source of truth" → "delegates to the resolved profile's `getInputDeviceArgs()` as the single source of truth for per-vendor input-device flags, so the segment command's input-side flags cannot drift from the profiles." - `HwaccelProfileFactory.php` (`getProfileForVendor` docblock, old ~:106): "shared by the whole-file and segment transcode paths" → "used by the segment transcode path (so the profiles and the emitted flags cannot diverge)." - Deliberately LEFT ALONE (perf-9's refs there were stale/wrong): `SoftwareProfile.php:21` (references the LIVE `buildCmafCommand()`, correct) and `TranscodeManager.php:2006` (unrelated to this method). **Acceptance mapping / verification:** - `php -l` on all 3 touched files: clean. - phpstan L9 (`-c phpstan.neon.dist --level=9 --memory-limit=512M --no-progress`): **[OK] No errors** — the real proof no dangling symbol/reference remains. - phpcs PSR12 on the 3 changed files: **0 errors** (1 pre-existing line-length WARNING at `FfmpegRunner.php:954`, outside my diff; the `SubtitleBurnerTest`/`SubtitleStyleOptionsTest` snake_case-method-name errors are pre-existing on HEAD in files I did not touch). - `phpunit --filter FfmpegRunner`: **OK (60 tests, 254 assertions)**. - `phpunit tests/Unit/Media/Transcoding/`: **OK (343 tests, 1182 assertions)** — the SubtitleBurnIn live-path test methods stay green. ## Implementer — SV-4.2-disconnect, Chunk 1 (shared-encode waiter ref-count landmine guard) — 2026-07-13 Implemented SS-1 (make waiters countable) + SS-2 (registry kills only when there is no OTHER waiter). Fixes the latent **shared/deduped-encode landmine**: client A launches+owns a segment encode keyed by its output path `$final`; client B (a second relay channel requesting the SAME `$final`) piggybacks with NO PID/group of its own. Before this change, A being cancelled → `SegmentProcessRegistry::killGroup($G_A)` → `kill($final)` → signalled the shared ffmpeg → B's poll times out → **B 404s** even though B still wants the segment. No new kill call site was added (Chunk 2 wires the direct-disconnect caller); this chunk only makes the EXISTING `killGroup`/`kill` waiter-aware. ### Files changed (all absolute under /home/sites/phlix/phlix-server) - **`src/Media/Transcoding/TranscodeManager.php`** (SS-1): - New `private array $segmentWaiters = []` — per-segment waiter ref-count keyed by `$final` (bounded: entry removed when count hits 0; every increment matched by a `finally` decrement). - New `incrementSegmentWaiter()` / `decrementSegmentWaiter()` (private) + public predicates `hasOtherWaiter(string $final): bool` (= `waiterCount > 1`) and `waiterCount(string $final): int`. - `produceSegment()` (video) and `produceAudioSegment()` (audio): increment as the FIRST statement inside the poll `try` (covers BOTH the launcher and the piggyback branch, before any launch/yield); decrement as the FIRST statement inside the `finally` (unconditional). Registry release/killGroup lines are otherwise untouched. - Design invariant (documented in code): `killGroup`/`kill` only reaches a still-tracked `$final` while its LAUNCHER is still in its poll (the launcher's `finally` drops the key + decrements on exit and tears down the group link), so the launcher always contributes exactly 1 to the count. `count > 1` therefore means "a genuine piggybacker (besides the one being cancelled) still wants the segment." No `?int $excluding` needed — the "> 1" shape answers SS-2's question exactly. - **`src/Media/Transcoding/SegmentProcessRegistry.php`** (SS-2): - New `private (callable(string):bool)|null $hasOtherWaiter` + `setWaiterGuard(?callable): void`. - `kill()` now consults the guard FIRST (before the drop): if another waiter is present it DEFERS — returns 0, signals nothing, cleans no temp, and LEAVES the entry fully tracked (PIDs, temps, group links) so the encode keeps serving the remaining waiter(s) and a later kill (once they leave) can still reap it. With no other waiter (guard null OR returns false — the common sole-cancel case, and every direct-construct test) it signals + reaps EXACTLY as before. Guard covers both `killGroup` (loops `kill` per key) and any direct `kill`. - Class/`killGroup` docblocks updated to describe the landmine guard. - **`src/Common/Container/Providers/TranscodeServicesProvider.php`** (SS-2 DI wiring): - The `TranscodeManager` factory now, after building `$manager`, grabs the SAME per-worker `SegmentProcessRegistry` singleton already injected into `FfmpegRunner` and calls `$registry->setWaiterGuard(fn($key) => $manager->hasOtherWaiter($key))`. Setter-based (no ctor/DI shape change), breaking the registry↔manager cycle. Shared provider → BOTH entrypoints (`public/index.php` + `start.php`) get it with one edit; no dual-entrypoint divergence. Resolving `TranscodeManager` always precedes launching (hence registering) any encode, so the guard is guaranteed set before any kill can find a key to reap. ### Tests (mutation-proof) - **`tests/Unit/Media/Transcoding/SegmentProcessRegistryTest.php`** (+5): `kill` defers when another waiter present (entry LEFT tracked, nothing signalled/cleaned); `kill` signals once the other waiter has left; `kill` signals when the launcher is the sole waiter (no relay-cancel regression); **mirrored relay regression** `killGroup` defers with a second channel waiting then reaps after it leaves; `killGroup` signals when the sole channel waiter. Existing `killGroup`/temp cases unchanged. - **`tests/Unit/Media/Transcoding/TranscodeManagerTest.php`** (+3): sole requester → waiterCount==1, hasOtherWaiter false, returns to 0 (no leak); **two concurrent requesters** for the same `$final` (real Swoole coroutines — launcher spawns a piggyback inside its launch callback and yields) → waiterCount reaches 2, hasOtherWaiter true, returns to 0 after both finish; audio-only path (`produceAudioSegment`) also ref-counts + returns to 0. The pre-existing SV-4.2 `killSegmentProcess`-never / release-only assertions remain green. ### Acceptance mapping - *SS-1 waiters countable in both video+audio launcher+piggyback branches, decremented in finally, no leak* → `segmentWaiters` + inc/dec in both `produceSegment`/`produceAudioSegment` (tests: solo/concurrent/audio waiter-count tests, all asserting return-to-0). - *SS-1 predicate for "another waiter besides the one being cancelled"* → `hasOtherWaiter()` (= count > 1); `waiterCount()` exposed for tests. - *SS-2 registry kills only when no OTHER waiter; preserves existing relay behavior in the common no-other-waiter case* → `kill()` guard (defer vs signal) + DI wiring (tests: registry defer/signal + mirrored relay `killGroup` regression + sole-waiter no-regression). ### Verification (real numbers) - `php -l` on all 5 files: clean. - **phpstan L9 (`-c phpstan.neon.dist`) on the 3 changed src files: [OK] No errors.** On the 2 changed test files: only 2 PRE-EXISTING errors (`TranscodeManagerTest.php:1723` list-offset, `:1920` unused-`$captOut` — both confirmed present on clean HEAD via `git stash`, in tests I did not write; phpstan's gate is `src` only regardless). - **phpcs PSR12 on the 3 changed src files: 0 errors** (only pre-existing >120-char WARNINGS, none on my added lines). Test-file snake_case method names match `SegmentProcessRegistryTest`'s existing per-file convention; phpcs gate is `src/` only. - **`phpunit --testsuite Unit --filter 'Transcode|SegmentProcess|Ffmpeg|RelayConsumer|RequestContext'` → OK (280 tests, 1293 assertions).** `SegmentProcessRegistryTest` alone: 22 OK (was 17); `TranscodeManagerTest` alone: 93 OK (was 90). - Note (pre-existing, NOT mine): `tests/Integration/Media/Transcoding/FfmpegHlsTranscodeTest` errors with `FfmpegRunner::startHlsTranscode()` undefined — that method was removed by a prior step and this chunk does not touch `FfmpegRunner`; the failures are in the INTEGRATION suite and pre-date this change (full Unit suite is the Test agent's gate). - Committed + pushed directly to master. ## Reviewer (per-step) — SV-4.2-disconnect, Chunk 1 (waiter ref-count guard) — 2026-07-13 Reviewed commit `07fc71b4` (on `91a31eb0`): 3 src + 2 test files. Verified the mechanical implementation is correct: the ref-count is incremented as the first statement inside the poll `try` (TranscodeManager.php:919 video, :1148 audio) BEFORE any launch/yield and decremented first in the `finally` (:965, :1186) — airtight pairing, no leak path (the only pre-`try` throw is the cap `SegmentBusyException` at :907/:1137, before any increment). The registry guard is null-safe (SegmentProcessRegistry.php:306, short-circuits when unset → pre-change behavior), the `> 1` predicate is exact for the launcher-contributes-1 case, and the DI wiring binds the guard to the same singleton `SegmentProcessRegistry` that `FfmpegRunner` uses (one production `new TranscodeManager`, one `setWaiterGuard` call). `php -l` clean on all three src files. RelayConsumer::onHttpCancel is untouched (killGroup call unchanged; defers transparently). Findings: 1. [Medium] `SegmentProcessRegistry::kill()` (SegmentProcessRegistry.php:306-335) narrows but does NOT fully close the shared-encode landmine, and the commit message / docblock overstate the guarantee. A non-deferred kill signals the ffmpeg + removes the PID + cleans the `.part-*` temp, but does NOT invalidate the manager's dedup reservation `segmentEncodesInFlight[$final]` (set at TranscodeManager.php:887/1131; read by segmentEncodeInFlight() :1428 via the dedup check at :881/1130). A requester that dedups onto `$final` AFTER a kill — but before the launcher's own poll-timeout `finally` clears the reservation (:980/1188) or the reconcile self-heal fires (SEGMENT_INFLIGHT_STALE_GRACE_MS = 5000, up to ~5s) — piggybacks onto a killed encode whose `$final` will never publish, polls to `segmentMaxWaitMs`, and 404s. This bites even the plain sole-launcher-cancel case (count = 1 at kill → not deferred), not just concurrency subtleties; the guard only protects requesters ALREADY counted at kill time. Why it matters: the exact scenario the chunk targets (two hub channels / two viewers on the same `$final`) can still 404 a requester whose request arrives during the ~5s stale-reservation window. Mitigating: pre-existing coupling gap (Chunk 1 is a strict improvement over the prior always-kill behavior) and the client retry self-heals (transient 404), which is why this is Medium not High — but the commit's unqualified "closes the latent relay-path bug (two hub channels requesting the same $final)" and the hasOtherWaiter docblock (TranscodeManager.php:1207-1222) claim more than is delivered. Fix options: (a) on a real (non-deferred) kill, also clear `segmentEncodesInFlight[$final]` + the snapshot (needs a registry→manager callback, mirroring the guard wiring in reverse), OR (b) downgrade the claim to "narrows the concurrent-waiter case" and explicitly document the residual (client retry + reconcile-grace) as the backstop. 2. [Low] The "a later kill reaps it once they leave" invariant (SegmentProcessRegistry.php:299-305; class docblock :52-57; TranscodeManager.php comments) is not realized in production. After a deferred cancel, NO second kill fires on either path: the relay cancel (RelayConsumer.php:1541) and any direct onClose fire ONCE; the piggybacker is `!reserved` so it never calls startSegmentEncode (TranscodeManager.php:920-945) and never registers a group — only the launcher's group ever contains `$final`; and the launcher's `finally` uses release-not-kill (releaseSegmentProcessAfterWaitTimeout, :997). So a deferred encode is actually reaped by natural publish or the `timeout ` wrapper, never by "a later kill." The registry tests `test_kill_signals_once_the_other_waiter_has_left` and `test_kill_group_defers_when_a_second_ channel_still_waits` assert a second-kill-reaps mechanism that production never triggers, so they don't reflect the real reap path. No leak (the launcher's `finally` always drops the registry entry; `timeout ` kills the ffmpeg), hence Low. Fix: correct the comments to name the real reaper (launcher release + `timeout `), which also removes the mental-model that masks Finding 1. 3. [Low] Test-coverage gaps. (a) No test exercises the REAL DI-wired guard (TranscodeServicesProvider.php:168, `fn => $manager->hasOtherWaiter($key)`) against a REAL `SegmentProcessRegistry::kill()` during a REAL concurrent `produceSegment` + cancel — the registry tests inject a FAKE guard closure and the manager tests never call kill(), so the end-to-end wiring (does a real kill defer while a real piggyback is parked in its poll?) is unproven; a broken `setWaiterGuard` binding would stay green. (b) No leak-on-exception test (a `produceSegment`/`produceAudioSegment` throwing mid-poll — e.g. SegmentCacheFullException from ensureDiskSpace at :931 — still decrementing its waiter); the `finally` makes it airtight by construction but only reasoning, not a test, asserts it. (c) The one genuine-concurrency test is `extension_loaded('swoole')`-gated and SKIPS (not fails) where swoole is absent — minor here (swoole is present in this environment), but a non-swoole CI lane would silently lose the only real coroutine-scheduling proof. 4. [Info] The guard callable is invoked without a try/catch (SegmentProcessRegistry.php:306). If `hasOtherWaiter` ever threw, `kill()` would abort before reaping (fail-unsafe). In practice it is a pure array read (`($this->segmentWaiters[$final] ?? 0) > 1`, TranscodeManager.php:1223-1225) that cannot throw, so no live risk — noted only for defensiveness. 5. [Info] Doc drift at the relay call site: the comment in RelayConsumer::onHttpCancel (src/Hub/RelayConsumer.php ~1534-1539) still says the encode is killed "immediately rather than running to completion," which is no longer unconditionally true now that `killGroup` can defer per-key when a piggybacker is present. Chunk 1 updated the SegmentProcessRegistry class/killGroup docblocks but not this consumer-side comment. Cosmetic. Count: 5 findings (1 Medium, 2 Low, 2 Info). No High / no regression — the delivered ref-count + defer mechanism is correct; the Medium concerns an overstated closure claim + a residual (largely pre-existing) dedup-onto-corpse window. ## Implementer — SV-4.2-disconnect, Chunk 2 (direct-LAN disconnect→kill wiring) — 2026-07-13 Implemented SS-3 + SS-4 on top of Chunk 1 (`07fc71b4`). Closes the confirmed direct-LAN bug: a client hitting the :8096 HTTP worker DIRECTLY (not via the hub relay) that disconnects mid-encode did NOT get its ffmpeg killed — only the relay path (`RelayConsumer::onHttpCancel` → `killGroup(channelId)`) killed. Root cause: direct requests carried no cancel group, so `TranscodeManager::produceSegment` registered the encode under `group=null` and nothing could reap it on disconnect. Used the audit-recommended REUSE approach — the direct path publishes into the SAME `RequestContext` cancel-group key the relay path reads, so **`TranscodeManager` needed ZERO edits** (confirmed: `getRelayCancelGroup()` reads at `TranscodeManager.php:943` video / `:1169` audio are untouched). ### Files changed (absolute under /home/sites/phlix/phlix-server) - **`src/Server/Http/RequestContext.php`** (SS-3): broadened the `KEY_RELAY_CANCEL_GROUP` docblock + `setRelayCancelGroup`/`getRelayCancelGroup` docblocks to state the key holds a relay channel id OR a per-request direct-connection cancel id, and documented WHY one key safely serves both (the two transports never share a coroutine — relay dispatch runs in the `phlix-relay-tunnel` worker, direct in the `phlix-server-http` workers; separate processes/registries). Added thin transport-neutral aliases `setCancelGroup()`/`getCancelGroup()`/`clearCancelGroup()` that delegate to the same key so the direct path (`HttpHandler`) reads naturally. **No second key; no `TranscodeManager` edit.** - **`src/Server/Workerman/HttpHandler.php`** (SS-4): - New `private const DIRECT_CANCEL_PREFIX = 'dl-'` + `private static int $directCancelSeq = 0` (a resident-worker monotonic counter — NOT request state) + `private static mintDirectCancelId()` returning `"dl-"`. Unique across BOTH concurrent connections AND sequential keep-alive requests on one connection (bare `spl_object_id($connection)` repeats across sequential keep-alive requests — deliberately NOT used). `++` carries no coroutine yield point so it is effectively atomic across a worker's coroutines. Prefix keeps direct ids visually distinct from integer relay channel ids (belt-and-braces; the registries are never the same instance anyway). - New `private armDirectCancelHook(TcpConnection): string` — mints the id, publishes it via `RequestContext::setCancelGroup($id)`, resolves the shared per-worker `SegmentProcessRegistry::class` singleton from the container, and sets `$connection->onClose = static fn() => $registry->killGroup($id)`. `start.php:389` wires only `$w->onMessage` (no worker-level `onClose`), so the per-connection hook clobbers nothing. - New `private disarmDirectCancelHook(TcpConnection): void` — `RequestContext::clearCancelGroup()` + `$connection->onClose = null`. - `__invoke`: calls `armDirectCancelHook($connection)` immediately BEFORE the `$this->application->dispatch($request)` line (`:179` region) — the /hls, /dash, /stream encode routes are owned by that Application router, and early-return paths (static file, media direct- play, avatar, artwork) never reach it. Added `disarmDirectCancelHook($connection)` as the FIRST statement in the existing `finally` (before `recordRequestMetrics`), so a NORMAL completion (encode already released by `produceSegment`'s finally) resets `onClose` and a later real socket close can't fire a stale `killGroup` against a reused-object connection. Crucially, when the client disconnects WHILE the handler coroutine is parked in `produceSegment`'s yieldable poll, `__invoke` has NOT returned → `finally` has NOT run → `onClose` is still armed → the event loop fires it → the encode is killed. Added imports for `SegmentProcessRegistry` + `RequestContext`. **Chunk-1 guard inherited for free:** the new `onClose` is just another caller of the existing waiter-aware `killGroup`. A piggybacking peer still waiting on the same `$final` defers the kill (Chunk 1) — verified by a dedicated test — so a disconnecting owner won't 404 a still-waiting peer. The guard is NOT bypassed. ### Dual-entrypoint `HttpHandler` is Workerman/Swoole-only (used solely by `start.php`; `public/index.php` merely mentions it in a doc comment — grep-confirmed it is never invoked there). FPM/CGI has no persistent `TcpConnection`/event loop, so there is nothing to hook and no `index.php` mirror is needed. The `RequestContext` docblock/alias change is shared code but harmless under FPM (it just never sets a direct group). ### Tests - **`tests/Unit/Server/Workerman/HttpHandlerDirectCancelHookTest.php`** (+8 tests, 37 assertions): id uniqueness+monotonicity across sequential AND concurrent invokes; `arm` publishes the id into the cancel group (readable via both `getCancelGroup()` and `getRelayCancelGroup()` — same key); `onClose` closure fires `killGroup` and signals + drops the registered PID (real `SegmentProcessRegistry` with a spy signal sender); `onClose` no-ops when nothing registered; **Chunk-1 defer inherited** (a true waiter guard → `onClose` signals nothing + leaves the encode fully tracked); `disarm` clears the group AND nulls `onClose`; and a full **`__invoke` integration** test proving `onClose` + the published group exist DURING dispatch (captured via a stub `Application::dispatch` that registers an encode under the group as `TranscodeManager` would), `onClose` is reset + the group cleared in the `finally` after normal completion, and the closure captured mid-dispatch still kills the request-group encode. - OUT OF SCOPE for unit tests (owed on-box verify, stated in the test docblock): the real socket-close→`onClose` timing while the coroutine is parked in `Coroutine::sleep`. ### Verification (real numbers) - `php -l` clean on all 3 changed files. - **phpstan L9 (`-c phpstan.neon.dist`): [OK] No errors** on both changed src files AND on the new test file. - **phpcs PSR12: 0 issues** on both changed src files AND the test file. - **New test file: OK (8 tests, 37 assertions).** - **Filtered `--testsuite Unit --filter 'HttpHandler|RequestContext|SegmentProcess|Transcode'`: OK (275 tests, 1054 assertions).** (The dedicated Test agent runs the FULL Unit suite later.) ### Acceptance mapping - *SS-3 reuse the relay cancel-group key for the direct path, no TranscodeManager edit* → RequestContext docblock broadening + `setCancelGroup`/`getCancelGroup` aliases delegating to `KEY_RELAY_CANCEL_GROUP`; TranscodeManager unchanged (tests assert the alias and `getRelayCancelGroup` return the same value). - *SS-4(a) per-request unique id, unique across concurrent + sequential keep-alive* → `mintDirectCancelId()` + monotonic `$directCancelSeq` (tests: sequential + concurrent uniqueness). - *SS-4(b) publish before dispatch* → `armDirectCancelHook` called immediately before `application->dispatch` (integration test asserts the group is set during dispatch). - *SS-4(c) singleton registry + onClose → killGroup* → `armDirectCancelHook` resolves the singleton and sets `onClose` (tests: onClose fires killGroup + drops the encode). - *SS-4(d) clear group + reset onClose in finally* → `disarmDirectCancelHook` in the `finally` (tests: disarm clears + nulls; integration asserts reset after normal completion). Committed + pushed directly to master (see final commit hash in the Orchestrator note / commit log). ## Reviewer (cumulative — Chunk 2 `495912c1` + SV-4.2-disconnect seam across both chunks) — 2026-07-13 Reviewed Chunk 2 (`495912c1`: RequestContext aliases + HttpHandler arm/disarm + 8 tests) for correctness AND the integration/seam with Chunk 1 (`07fc71b4`) end-to-end through `TranscodeManager::produceSegment`/`produceAudioSegment`, `SegmentProcessRegistry`, and the relay `RelayConsumer::onHttpCancel`. Read the DI wiring (`TranscodeServicesProvider`) and `start.php` worker bootstrap. **Chunk 2's mechanical wiring is correct.** Verified positively (NOT findings): - **Registry singleton identity (item 4): OK.** `start.php` builds one `ContainerFactory::create()` per worker (`start.php:154`) and passes that SAME `$container` to both `Application` (:172) and `new HttpHandler($container, ...)` (:389-395). PHP-DI `factory()` entries are cached/shared, so `HttpHandler::armDirectCancelHook` → `$this->container->get(SegmentProcessRegistry::class)` returns the identical singleton that `FfmpegRunner::setSegmentProcessRegistry` (provider :113-114) registers PIDs into. The kill targets the populated registry. - **id uniqueness/collision (item 1): OK.** `dl-` prefix + per-worker `static $directCancelSeq`; `++` has no coroutine yield point (cooperative scheduling) so it is atomic within a worker. Relay channelIds are minted in the SEPARATE `phlix-relay-tunnel` worker (`start.php:627/663` builds its own container → own registry + own `support\Context`), so the two transports never share a coroutine, a registry, or a Context — no collision is possible even though both publish into `KEY_RELAY_CANCEL_GROUP`. Cross-worker `dl-N` duplication is harmless (per-worker registries). - **onClose does not clobber worker bookkeeping (item 3): OK.** `start.php` wires only `$w->onMessage` (no worker-level `onClose`), so accepted connections start `onClose=null`; arm sets, disarm nulls — Workerman's internal `destroy()` bookkeeping is unaffected. - **Context is coroutine-local: OK.** `RequestContext` proxies `support\Context` (per-coroutine isolation), so concurrent direct requests on DIFFERENT connections each carry their own cancel group and cannot trample each other; the onClose closure captures `$id` directly (not via Context), so it is Context-independent. - **No collateral from always-setting the cancel group: OK.** Grep confirms the ONLY readers of `getRelayCancelGroup()` are `TranscodeManager.php:943/1169` (passed as the encode's registry group). Nothing branches on "is this a relay request?" via this key, so Chunk 2 now publishing a non-null `dl-N` for every dispatched direct request has no side effect beyond encode registration (the intent). - **Mutation sense of the 8 tests (item 8): mostly OK.** `testMintsUniqueMonotonicIdsAcrossSequential Invocations` goes red if the id were `spl_object_id`-based (non-monotonic on a reused keep-alive connection); `testDisarmClearsCancelGroupAndNullsOnClose` + `testInvokeArmsHookBeforeDispatchAnd ResetsInFinally` go red if `disarm` did not null `onClose` or if `arm` were placed after dispatch. Defer-inheritance is covered. Gaps noted in Finding 4 below. Findings: 1. [Medium — INTEGRATION REFINEMENT of Chunk-1 per-step Medium #1; NOT a new defect, elevated frequency + concrete safe design for the Fixer] The dedup **reservation `segmentEncodesInFlight [$final]` is not invalidated when a kill reaps the encode**, and Chunk 2 turns disconnect-kill into a COMMON trigger (every abandoned direct-LAN scrub), so the "dedup-onto-a-killed-corpse → 404" window (`TranscodeManager.php:887/1131` set; read via `segmentEncodeInFlight()` :1426/:881/:1130) now bites the ordinary direct path, not just two-hub-channel relay races. Scenario (multi-device, the targeted case): client A (direct) launches + is mid-encode on `$final`; A disconnects → `onClose` → `killGroup(dl-A)` → `kill($final)` — the waiter guard sees NO other waiter (B has not arrived yet, count==1) → it SIGNALS ffmpeg + cleans the `.part-*` + drops the registry entry, but `segmentEncodesInFlight[$final]` stays set. Client B arrives ~200 ms later for the same `$final`, `segmentEncodeInFlight($final)` is still TRUE → B piggybacks onto the corpse, polls to `segmentMaxWaitMs`, and **404s** until the reservation clears via either A's still-parked coroutine's own poll-timeout `finally` (`:980/:1188`, A's socket close does NOT interrupt its coroutine) OR the reconcile self-heal (`reconcileInFlightSegments` :1507-1518, up to `SEGMENT_INFLIGHT_STALE_GRACE_MS`=5000 ms from launch, since the `.part-*` was removed by the kill so the snapshot no longer backs it). **Real severity: Medium** — a transient ≤~5 s 404 burst that hls.js self-heals by retrying; single-client-retry-on-new-connection and multi-device-same- segment both hit it, but only within that bounded window. Why it still matters: Chunk 2's own docblocks/commit ("registers the encode under this id with ZERO extra wiring", "the kill is waiter-aware ... defers it") read as if the shared-encode case is fully closed; it narrows but does not close it. **Concrete, safe fix design for the Fixer (this is the landmine — read before touching it):** the naive fix "on a real (non-deferred) kill, also `unset($this->segmentEncodesInFlight[$final])`" RE-OPENS the SV-4.1 double-encode race AND adds a registry cross-clobber, because BOTH the reservation map and the registry are keyed by a BARE `$final` string with no launcher identity, and the launcher's `finally` clears them UNCONDITIONALLY (`:980` unset + `:994-998` `releaseSegmentProcess`/`releaseSegmentProcessAfterWaitTimeout`, the latter → `registry-> releaseAfterWaitTimeout($final)` → `drop($final)`). Break-sequence with the naive fix: (a) A reserves `$final`, launches, parks; (b) A disconnect-kill invalidates the reservation; (c) NEW launcher B passes the now-false dedup check, reserves `$final`, launches a FRESH encode + registers its PID under `$final`; (d) A's still-parked coroutine times out and its `finally` runs `unset(segmentEncodesInFlight[$final])` (clobbers B's fresh reservation → a THIRD requester double-encodes) AND `releaseSegmentProcessAfterWaitTimeout($final)` → `drop($final)` (clobbers B's registry tracking → B's encode can no longer be cancelled on B's disconnect). Note the current (unfixed) code is safe from this ONLY because the leaked reservation is exactly what serializes launchers on `$final` — so any invalidate-on-reap MUST restore that serialization with a token: - Give each reservation a launcher **generation token**: store `segmentEncodesInFlight[$final] = ['at' => monotonicMs, 'gen' => ++$this->reservationSeq]` (the current bare `monotonicMs()` marker is NOT a safe token — ms resolution can tie between two launchers); the launcher captures its own `$myGen`. - Make the launcher's `finally` a **compare-and-clear**: only `unset` the reservation AND only call the registry release for `$final` when `(segmentEncodesInFlight[$final]['gen'] ?? null) === $myGen`; otherwise it is a complete no-op (a newer launcher B now owns `$final`). This is the load-bearing coupling — the reservation-gen and the registry-ownership must be gated together. - Add an **invalidate-on-reap callback** on `SegmentProcessRegistry` (mirror of the Chunk-1 waiter-guard wiring, in reverse): only on the SIGNALLED branch of `kill()` (past the defer guard, `SegmentProcessRegistry.php:314+`) call `$manager->invalidateReservation($final)`, which clears `segmentEncodesInFlight[$final]` (+ the `globalInFlightSnapshot` entry). Because kill() reaps the current sole owner and the launcher's `finally` is now gen-guarded, the killed launcher's later `finally` cannot re-clobber B. Do NOT invalidate on the DEFERRED branch. - Cover BOTH `produceSegment` (video) and `produceAudioSegment` (audio) — identical reservation shape at `:1131/:1188`. 2. [Low — new, Chunk-2-specific] **Per-connection `onClose` + per-request arm/disarm assumes strict request serialization on a connection, which the Swoole coroutine loop does not guarantee under HTTP pipelining.** `$connection->onClose` is a single per-connection slot, but each `onMessage` runs in its own coroutine and `produceSegment` yields (`Coroutine::sleep` :951-952). If a second request is delivered on the SAME keep-alive connection while request 1 is parked mid-encode (HTTP/1.1 pipelining, or simply a fast follow-up the event loop dispatches during the park), request 2's `armDirectCancelHook` OVERWRITES request 1's armed `onClose`, and request 2's `finally` → `disarmDirectCancelHook` NULLS it (`HttpHandler.php:292/347-350`) — even a trivial non-streaming request 2 that early-returns still runs the `finally` disarm. Net: request 1's disconnect-kill is silently lost and its encode falls back to the `timeout ` backstop. Failure mode is a MISSED kill (degrades to pre-Chunk-2 behavior), never a wrong-kill or crash, and mainstream clients (browsers / hls.js) do not pipeline segment fetches — hence **Low**. But the code comments assert "keep-alive serves sequentially" as load-bearing, which is not strictly true under the coroutine loop. Fix direction: (a) at minimum, document the assumption honestly; (b) cheap partial guard — capture the exact closure armed by THIS request and in `disarm` only null when it is still identical (`if ($connection->onClose === $armedClosure) $connection->onClose = null;`), preventing request 2's disarm from nulling request 1's live hook; full correctness under overlap would need a per-connection id→closure map rather than a single slot. 3. [Info — INTEGRATION observation on Chunk-1 Low #2 / all-waiters-disconnect on a SHARED encode; item 6] When A launches and B piggybacks on the SAME `$final` (B is `!reserved` at `TranscodeManager.php:920-923`, so it registers NO PID and NO group), a disconnect by A defers (guard: B still parked) and a subsequent disconnect by B is a genuine **no-op** (`killGroup(dl-B)` finds no keys — B never registered one). So after BOTH leave, neither disconnect reaps the encode. This is **acceptable and should be documented as such, not "fixed"**: `startSegmentEncode` encodes a single bounded segment (~`segment_seconds` of content), so it completes within seconds and publishes `$final`; A's and B's coroutines keep polling despite the socket closes and exit on `is_file`, and A's `finally` plain-releases the registry entry. No CPU runaway (bounded work), no leak. The `timeout ` wrapper remains the ONLY backstop for a genuinely STUCK (not merely abandoned) shared encode — do not advertise disconnect-kill as covering that. A reap-on-last-waiter- leave would be a marginal improvement but is not warranted given the bounded self-limit; record it as a known accepted tradeoff. 4. [Info — relay parity, item 7 + test gap, item 8] (a) **Relay parity confirmed:** `RelayConsumer:: onHttpCancel` (`RelayConsumer.php:1541`) reaps via the SAME `SegmentProcessRegistry::killGroup` → `kill()`, so BOTH the Chunk-1 defer AND the Finding-1 reservation-invalidation gap apply identically to the relay transport. The Fixer's invalidate-on-reap therefore belongs in the shared registry `kill()`→manager callback so it covers relay and direct with one change (do not special-case the transport). Also carry the cosmetic Chunk-1 Info #5 doc fix at `RelayConsumer.php:1534-1539` ("killed immediately ... rather than running to completion" is no longer unconditionally true). (b) **Test gaps:** no end-to-end test wires a REAL `HttpHandler` onClose → REAL `TranscodeManager` reservation to demonstrate the Finding-1 dedup-onto-corpse 404 window (a regression there would stay green — same class as Chunk-1 Reviewer finding 3a); the same-connection-pipelining onClose-clobber (Finding 2) is untested; and there is no test that an EARLY-return request (before `arm`, e.g. static/media-stream) still disarms idempotently. The on-box real-socket-close→onClose timing is correctly out-of-scope and not counted here. Count: 4 findings (1 Medium [integration refinement of Chunk-1 #1, with the concrete token-based fix + clobber landmine spelled out], 1 Low [new: same-connection onClose clobber under pipelining], 2 Info [all-waiters-disconnect accepted tradeoff; relay parity + test gaps]). No High. Chunk 2's wiring is correct and the singleton/id/Context/onClose mechanics all check out; the Medium is the load-bearing seam the Fixer must close carefully (bare-`$final`-keyed reservation+registry = the double-encode/ registry-clobber landmine). ## Fixer — SV-4.2-disconnect (close ALL findings from both review passes) — 2026-07-13 Closed every finding from the Chunk-1 per-step review (5) and the cumulative Chunk-2/seam review (4). Two commits: F1 alone first (concurrency change), then F2–F7. phpstan L9 + phpcs clean on all changed src; filtered Unit suites green. Origin master synced before each commit (local==remote, no rebase needed). ### F1 [MEDIUM] — invalidate the dedup reservation on reap (commit 1, `41ee8b3a`) Implemented the cumulative reviewer's generation-token compare-and-clear design AS SPECIFIED (no material deviation): - `TranscodeManager::$segmentEncodesInFlight` reservation value changed from a bare launch-ms `int` to `array{at:int, gen:int}`; `gen` minted from a new per-worker `$reservationSeq` counter (ms markers can tie between two launchers, so a monotonic counter is the safe token). - Launcher `finally` in BOTH `produceSegment` (video) and `produceAudioSegment` (audio) is now **compare-and-clear**: it clears the reservation AND calls the registry release ONLY while it still owns the current generation for `$final`. A stale launcher (its encode reaped, its coroutine timing out later) is a complete no-op → it cannot clobber a fresher launcher's reservation or drop its registry registration (guards the SV-4.1 double-encode race + the registry cross-clobber landmine). The over-cap rollback uses the same `clearReservationIfMine($final, $gen)` helper. - `TranscodeManager::invalidateReservation($final)` (new public) clears the in-worker reservation AND the cross-worker `globalInFlightSnapshot` entry so the ≤1s snapshot can't re-dedup onto the corpse. - `SegmentProcessRegistry::setReapCallback()` (new) + a `$onReap` invoked ONLY on the signalled branch of `kill()` (past the waiter-guard defer, with PIDs present) and BEFORE the coroutine-yielding SIGTERM→SIGKILL wait, so it can only clear the reaped launcher's reservation, never a fresh re-launch's. NOT invoked on the deferred branch, NOT when no PIDs. - Wired in `TranscodeServicesProvider` next to the existing `setWaiterGuard` (one shared registry singleton → covers relay `killGroup` AND direct `onClose` AND both video+audio with one binding). - Files: `src/Media/Transcoding/TranscodeManager.php`, `.../SegmentProcessRegistry.php`, `src/Common/Container/Providers/TranscodeServicesProvider.php`. - Tests (commit 1): registry-level — reap callback fires on genuine reap / NOT on defer / NOT on empty (`SegmentProcessRegistryTest` +3 = 25). Manager-level (`TranscodeManagerTest`) — re-launch-after-reap (i), deferred-no-invalidate, stale-launcher-finally no-clobber via a REAL `produceSegment` run (ii), audio gen-stamp (iv-audio), relay `killGroup` parity (v), dedup-intact-when-not-killed (iii, SV-4.1). Existing reconcile-shape tests updated to `{at,gen}`. Note: an arrow fn cannot declare `: void` — the reap-callback wiring uses a normal closure (caught by `php -l` pre-commit). ### F2 [claim-accuracy/doc] — corrected overclaiming docblocks/comments (commit 2) - `SegmentProcessRegistry` class docblock + `$hasOtherWaiter` docblock + `kill()` inline comment: the guard now says it NARROWS the shared-encode 404 window; the RESERVATION gap is closed separately by the F1 reap callback. Removed the "a later kill reaps it once they leave" claim everywhere — a DEFERRED encode is NOT re-killed later; it completes+publishes normally and is dropped by the launcher's own wait-timeout release (`timeout ` backstops a genuinely stuck one). - `TranscodeManager::hasOtherWaiter` docblock: clarified it only protects an ALREADY-parked piggybacker; a just-after-reap requester is handled by `invalidateReservation` (F1). ### F3 [Low, pipelining clobber] — identity-guarded disarm (commit 2) - `HttpHandler::disarmDirectCancelHook(TcpConnection, mixed $armed)`: clears the (per-coroutine) cancel group unconditionally, but nulls `$connection->onClose` ONLY when it is still the exact closure THIS request armed. `__invoke` captures `$armedOnClose = $connection->onClose` right after arming (declared `null` before the try so it's defined on every finally path incl. early returns). A pipelined 2nd request's disarm can no longer null a parked 1st request's live hook; an early-return request (`$armed = null`) leaves a parked sibling hook intact. Fails safe either way. - Tests: `testDisarmOnlyNullsTheClosureThisRequestArmed`, `testDisarmDoesNotNullAParkedHookWhenThisRequestNeverArmed`. ### F4 [Info] — guard try/catch (commit 2) - `SegmentProcessRegistry::kill()` now wraps the `hasOtherWaiter` guard call in try/catch: a throwing guard is treated as "no other waiter" and the kill PROCEEDS to reap (fail-safe — never strand a PID), logging a warning. Covered by the F4 change; the pure-array-read guard cannot throw in practice. ### F5 [Info] — RelayConsumer comment (commit 2) - `RelayConsumer::onHttpCancel` comment corrected: the kill is waiter-aware since SV-4.2-disconnect (killGroup DEFERS a key with a live piggybacker rather than killing immediately) and invalidates the reservation on a genuine reap (F1) — no longer an unconditional immediate reap. ### F6 [Info] — all-waiters-disconnect accepted tradeoff (commit 2) - Added a comment in `produceSegment`'s piggyback branch documenting that a piggybacker registers no registry PID/group, so if the launcher AND every piggybacker disconnect neither reaps the shared encode — INTENTIONAL and bounded (single-segment encode self-limits + coroutine poll-timeout + `timeout ` backstop). No reap-on-last-waiter machinery built. ### F7 — remaining test gaps (commit 2) - leak-on-exception: `testSegmentWaiterCountReturnsToZeroWhenPollBodyThrows` — the waiter ref-count decrements in the finally even when the poll body throws (no phantom waiter deferring future kills). - real-DI-guard integration: `TranscodeServicesProviderTest::test_provider_wires_real_waiter_guard_and_reap_callback` builds the FULL container and proves the provider binds the REAL `hasOtherWaiter` guard AND the REAL `invalidateReservation` reap callback (a broken binding goes RED; unit registry tests use fake closures and cannot catch that). Signalling neutralised via reflection so no real process group is hit. - e2e HttpHandler onClose → real reservation: `HttpHandlerDirectCancelHookTest::testOnCloseReapsPidAndInvalidatesRealManagerReservation` wires a REAL registry↔REAL TranscodeManager, arms the hook, registers a PID + reservation, fires onClose, asserts the PID is reaped AND the reservation invalidated (ties F1 + Chunk 2). - pipelining-clobber: the two F3 tests above. ### Verification (real numbers) - `php -l` clean on all changed files. - phpstan L9 (`-c phpstan.neon.dist`): [OK] No errors on all 5 changed src files (F1 subset + F2–F6). - phpcs PSR12: 0 ERRORS on all changed src (only pre-existing >120-char WARNINGS; none on added lines). - Filtered Unit `--filter 'Transcode|SegmentProcess|Ffmpeg|HttpHandler|RelayConsumer|RequestContext'`: OK (406 tests, 1632 assertions). Per file: TranscodeManagerTest 100, SegmentProcessRegistryTest 25, HttpHandlerDirectCancelHookTest 11, TranscodeServicesProviderTest 3, RelayConsumerTest 50. - Commits: F1 `41ee8b3a` (pushed), F2–F7 `` (pushed). Origin master synced. ## Reviewer (confirming re-review of reconcile-leak fix `074fe5dc`) — 2026-07-13 Loop-closing re-review of the F1 leak-regression fix (`reconcileInFlightSegments()` now releases the registry entry in both reservation-clearing branches). READ-ONLY. Verified adversarially against all 7 checkpoints. **NO FINDINGS** Verification detail (why the leak is cleanly closed with no regression): 1. **Leak closed / mirrors launcher `finally` exactly.** Completed branch (`is_file($final)` true, :1639) → `releaseSegmentProcess` (plain release); stale branch (non-`is_file`, past grace, :1653) → `releaseSegmentProcessAfterWaitTimeout`. Byte-equivalent to the launcher's own gen-gated finally (:1050-1054: `is_file` true→plain, false→wait-timeout) and to pre-F1 registry-release behavior. 2. **Exactly one release, no double-signal.** After reconcile unsets the reservation, the launcher's gen-gated finally reads `['gen'] ?? null === $myGen` → `null === $myGen` → no-op. Even under a hypothetical overlap, `release()`/`releaseAfterWaitTimeout()` both funnel to the idempotent `drop()` (unset of absent keys + group array_filter); neither ever calls the signalSender, so no double-kill is possible. 3. **No new clobber of a fresher launcher.** Both branches are gated by `isset($snapshot[$final]) → continue` (:1621). Curated Swoole hook mask (`SwooleRuntime::SAFE_HOOK_NAMES`) EXCLUDES `SWOOLE_HOOK_FILE`, so `glob()`/`is_file()` are blocking syscalls that do NOT yield → the reconcile loop is atomic within the coroutine. No launcher finally or fresher launcher can interleave between the frozen glob snapshot (:1618) and the per-entry release, so the registry key `$final` can only ever hold the stale/completed launcher's own entry. A fresher launcher would require the stale reservation to have already cleared (impossible without a mid-loop yield, since a live `.part-*` → `continue`). The only theoretical yield path (operator sets an explicit `coroutine.hook_flags` that re-enables file IO) violates a pre-existing, codebase-wide no-yield-in-reconcile assumption that the pre-existing reconcile-unset and `produceSegment`'s poll-loop `is_file` already depend on — NOT a regression introduced by this fix. 4. **Stale-branch release cannot kill a live encode.** `releaseAfterWaitTimeout()` (:307-330) never signals; it drops tracking and, only when `!$anyAlive`, cleans the launcher's OWN corpse temp (scoped — not the `{$final}.part-*` family). The stale branch is only reached when no live `.part-*` is in the snapshot (a slow/live encode's live temp → `continue`), so nothing wanted by a fresher requester is ever reached or killed. 5. **Audio parity.** `reconcileInFlightSegments()` is shared — it iterates `$segmentEncodesInFlight` populated by BOTH `produceSegment` (:915) and `produceAudioSegment` (:1191), registry keyed on `$final` in both. Dedicated audio test present. 6. **Test mutation-sense.** The 3 new tests assert registry-level drain (`registeredKeyCount()===0`, `pidsFor($final)===[]`, `registeredGroupCount()===0`) — NOT merely reservation-clear (`inFlightSet`) — plus exactly-one-release (`$releaseCalls===1` / `$waitReleases===[$final]`) and no-signal (`$signalled===[]`). They cover completed-video, completed-audio, and stale branches, and each enforces branch-correct release-method selection via `expects($this->never())` on the sibling method. Reverting the two added release calls makes the `$releaseCalls`/`registeredKeyCount`/`pidsFor`/`registeredGroupCount` asserts fail → RED. The fresher-launcher case is correctly untested (unreachable under the runtime; see #3). 7. **No new issue.** PHPStan L9 `[OK] No errors`; phpcs PSR-12 0 errors (10 pre-existing >120-char WARNINGS only, none on the added lines 1624-1654; verified all added lines ≤120 chars). Full `TranscodeManagerTest` 103 tests / 527 assertions green (the 3 new + 100 prior, no regression); the 3 filtered reconcile-supersede tests pass (24 assertions). Coroutine-safety preserved — the added releases are synchronous (`drop()` is pure array work), introducing no new yield. Non-blocking process note (not a code finding, does NOT require a Fixer loop): neither the prior confirming re-review's Medium finding nor the Fixer's `074fe5dc` fix was appended to this worklog; the commit message for `074fe5dc` is the only record of the fix rationale. Worklog hygiene only — the code and tests are complete and correct. Verdict: **NO FINDINGS** — the F1 reconcile-supersede leak is cleanly closed with no regression. Loop closed. ## Test — SV-4.2-disconnect — 2026-07-13 Owed full-suite verification across the 5 SV-4.2 commits (`07fc71b4` → `495912c1` → `41ee8b3a` → `5ed0e15c` → `074fe5dc`), plus real coverage on the changed files and the pre-existing broken `FfmpegHlsTranscodeTest`. Verification at HEAD `074fe5dc` (+ the two test commits below). DB not reachable on :3306 here — irrelevant: the Unit suite mocks the DB per convention and ran fully. ### 1. Full Unit suite (`./vendor/bin/phpunit --testsuite Unit`) REAL output (final, after adding the test in §2): Tests: 5316, Assertions: 40710, Skipped: 5. (exit 0 — OK) vs perf-10 baseline `5240 / 0 fail / 0 err / 11 skip`: test count +76 (SV-4.2 additions + 1 new test below), **0 failures, 0 errors**, skips 11→5 (fewer — environment-conditional skips, NOT a regression; no red introduced). First run before my test add was `5315 / 40705 / 0F / 0E / 5S`; adding the F4 test took it to 5316. No NEW failure/error vs baseline — clean across all 5 SV-4.2 commits. - **PHPStan L9** (`analyze -c phpstan.neon.dist`, 645 files): `[OK] No errors`. - **phpcs PSR-12** on the 5 changed src files: 0 ERRORS; 10 WARNINGS, ALL >120-char line-length and ALL in `TranscodeManager.php` at lines 452/514/1976/1977/2086/2250/2524/2525/2531/3281 — `git blame` confirms every one traces to a PRE-EXISTING commit (SV-3.3 `4dd9f7f0`, security #48 `52eadfde`, multi-audio `858f4942`, 10-bit HEVC `175a46a0`, P3+B1 `42d9b7c4`) — NONE from the SV-4.2 commits. ### 2. Coverage on the SV-4.2 changed files (pcov, full Unit suite scoped to the 5 files) Whole-file line coverage (aggregate, dominated by pre-existing code in these large files): TranscodeServicesProvider 96.20% (76/79) RelayConsumer 67.76% (414/611) SegmentProcessRegistry 77.50% (93/120) → 100% on kill() after §2 fix TranscodeManager 86.46% (958/1108) HttpHandler 55.22% (312/565) Per-SV-4.2-method line coverage (clover, the surfaces named in the step) — ALL 100% after the fix: SegmentProcessRegistry: register 8/8, release 1/1, releaseAfterWaitTimeout 10/10, registeredKeyCount/registeredGroupCount/pidsFor 1/1, drop 12/12, kill() waiter-guard 30/30 (was 24/30 — see below) TranscodeManager: clearReservationIfMine 2/2, invalidateReservation 1/1, reconcileInFlightSegments (incl. reconcile-release fix) 24/24 HttpHandler: armDirectCancelHook 7/7, disarmDirectCancelHook 4/4, onClose arm site 2/2, disarm finally 1/1 **Gap found + closed:** `SegmentProcessRegistry::kill()` had 6 uncovered lines (362, 367–371) — the **F4 fail-safe catch** (waiter-guard throws → swallow → proceed to reap) added by fix commit `5ed0e15c`. Added a focused test `test_kill_proceeds_to_reap_when_waiter_guard_throws` (guard throws `RuntimeException` → asserts SIGTERM signalled, orphan `.part` cleaned, reap callback fires, no leak). Re-ran: those 6 lines now cnt≥1 → kill() 100%. SegmentProcessRegistryTest 25→26 tests, green. ### 3. FfmpegHlsTranscodeTest (pre-existing broken Integration test — resolved) Symptom: 2 of its 4 methods errored `Call to undefined method FfmpegRunner::startHlsTranscode()`. Root cause: `startHlsTranscode()` (+ `buildTranscodeCommand`/`buildHlsCommand`/`buildHwaccelCommand`/ `buildTranscodeCommandWithProfile` + private `buildHwaccelInputFlags`) was removed as DEAD CODE by commit `015ea7a7` (SV-4.13 "Remove superseded whole-file command builders"). The whole-file HLS path was superseded by the on-demand per-segment encode path (`buildSegmentCommand`/`startSegmentEncode`, unit-covered) and the CMAF path. Decision: the 2 methods (`testDetachedHlsTranscodeProducesSegmentsAndPlaylist`, `testRemuxCopyPathProducesPlayableHls`) exercised a NON-EXISTENT method → **obsolete**; removed them (with an in-file note pointing to `015ea7a7`), leaving the 2 still-valid cases (`testProbeReadsCodecsFromGeneratedClip`, `testDetachedCmafTranscodeProducesBothDashAndHls` — `probe()`/`startCmafTranscode()` both still exist). File now: `OK (2 tests, 25 assertions)` — no longer erroring. phpcs on the file: clean (exit 0). ### Durable-state notes - `074fe5dc` closed the F1 reconcile-leak REGRESSION (registry entry now released in both reservation-clearing branches of `reconcileInFlightSegments()`); the confirming re-review recorded just above this entry was **NO FINDINGS**. Loop closed. - phpcs `--standard=PSR12` snake_case "camel caps" method-name errors in SegmentProcessRegistryTest are a file-wide PRE-EXISTING convention (all 26 `test_*` methods) and are NOT gated (the phpcs command targets `src/` only). The added test follows that same convention. ### Commits - `6c7e1c5f` — `SV-4.2 tests: cover kill() F4 fail-safe (throwing waiter guard proceeds to reap)` - `af31abc9` — `SV-4.2 tests: drop obsolete FfmpegHlsTranscodeTest whole-file HLS cases (startHlsTranscode removed in SV-4.13 015ea7a7)` **GREEN.** ## Implementer — SV-1.1 sub-step (b): thread resolved tone-map FILTER STRING through segParams — 2026-07-14 **Commit `6c115e04`** (on `da69c2e1`). Pushed to origin/master (in sync). phpstan L9 (src) clean, phpcs PSR12 clean on changed files, `--filter 'Transcode|Ffmpeg'` = 228/228 green (includes 11 new tests). NO caliber (standing directive). ### Verified anchors at HEAD (audit line refs had drifted post-SV-4.2) - `TranscodeManager::computeHlsParams` = **:2531**; sets `require_hdr_tone_map` at **:2574-2576** from `$colorMeta = extractColorMetadata($probe)` (**:2569**). - `TranscodeManager::computeSegmentParams` = **:1913** (calls computeHlsParams :1920; copy→libx264 upgrade :1922-1929). segment_params JSON persisted at **:545 / INSERT :552-561**. - `FfmpegRunner::buildSegmentCommand` tone-map gate = **:1685-1704** (was 1638-1645). `buildHwaccelSegmentCommand` = **:2016-2044** (was 1956-1969). `getToneMappingProfile` = **:485**, `needsToneMapping` = **:420**, `buildZscale/LibplaceboToneMapFilter` = **:560 / :624**. - Legacy single-variant decode (where `require_hdr_tone_map` is decoded) = `ensureSegment` **:741-750** (json_decode of the whole segment_params blob → $segParams). ### What was threaded + round-trip path 1. New **`FfmpegRunner::resolveToneMapFilterFromProbe(?array $probe, string $codec): ?string`** — single source of truth for the tone-map graph, resolves from an already-known probe WITHOUT probing. `getToneMappingProfile()` now delegates to it (`resolveToneMapFilterFromProbe($this->probe($inputPath), $codec)`) → byte-identical output. Extracted HDR-detection into private `isHdrColorMeta()` (shared by `needsToneMapping()` + the resolver) so the HDR decision is identical on both paths. 2. **`computeSegmentParams`** (:1935-1951): when `require_hdr_tone_map` is set, resolves `$params['tone_map_filter']` once via `resolveToneMapFilterFromProbe($probe, $videoCodec)` using the FINAL codec (`FfmpegRunner::paramString($params,'video_codec') ?? 'libx264'`, i.e. post copy→libx264 upgrade — exactly what buildSegmentCommand derives). It rides the SAME persisted segment_params JSON as `require_hdr_tone_map` and round-trips through the encode(json_encode :545)→decode(json_decode :741) legacy single-variant path. 3. **`buildSegmentCommand` / `buildHwaccelSegmentCommand`**: when `require_hdr_tone_map === true` AND `tone_map_filter` is present → append the threaded string DIRECTLY (zero `probe()`/`needsToneMapping()`/`getToneMappingProfile()`). Legacy re-derive kept ONLY as the `else`/`elseif` fallback for absent flag/string (pre-threaded persisted params / un-rescanned items). ### Byte-identity + SV-1.6 ordering - The threaded string is produced by the exact builder chain `getToneMappingProfile` uses (same probe, same codec, same `$this->config` on the resident FfmpegRunner instance), so the emitted ffmpeg `-vf` graph is unchanged for HDR content (WHERE-computed, not WHAT-changed). Verified in test by handing in the canonical SV-1.4 zscale graph and asserting it appears verbatim in `-vf`. - SV-1.6 ordering preserved: tone-map filter is pushed to `$filters[]` BEFORE the subtitle burn-in filter and BEFORE scale (unchanged insertion order). New test `testSoftwareSegmentThreadedFilterPrecedesScale` pins tone-map-before-scale; existing FfmpegRunnerSubtitleBurnInTest (green) guards burn-in ordering. ### Tests (real numbers) - New `tests/Unit/Media/Transcoding/FfmpegRunnerToneMapThreadingTest.php` (7 tests) + PSR-4 spy `ToneMapThreadingSpyRunner.php` (call-counting FfmpegRunner double): threaded path emits the exact graph with 0 probe/needsToneMapping/getToneMappingProfile calls (software + hwaccel); legacy fallbacks re-derive exactly once; flag-gating + ordering. Mutation sense: goes red if the builders re-derive instead of using the threaded string. - Added to `TranscodeManagerTest`: `testEnsureHlsJobThreadsResolvedToneMapFilterForHdrSource` (HDR → resolver called ONCE with 'libx264'; `tone_map_filter` present in decoded segment_params) + `testEnsureHlsJobOmitsToneMapFilterForSdrSource` (SDR → resolver never called, key absent). `stubColorMetadata()` left intact. - `--filter 'Transcode|Ffmpeg'`: **OK (228 tests, 1058 assertions)**. phpstan L9 on src (2 files) + new test files: **No errors**. phpcs PSR12 `-n` on changed files: **0 errors** (pre-existing line-length WARNINGS in TranscodeManager/TranscodeManagerTest are outside my added ranges). ### SCOPE NOTE for orchestrator (NEXT pass, not mine) - **Sub-step (a)** — read persisted `media_streams` color columns (mig 073) to reconstruct the HDR decision at `ensureHlsJob` so scanned items hit **0 HDR-probes** (today always exactly 1 live probe) — is the NEXT pass, OUT OF SCOPE here. Did NOT touch scanner and added NO migration. - Observed (pre-existing, informational): `require_hdr_tone_map` (and hence the new `tone_map_filter`) is threaded through the **legacy single-variant** segment_params only. The multi-variant/ABR path (`ensureSegment` :719 → `segmentParamsForRendition` :1435) rebuilds params fresh per-rendition and carries NEITHER flag, so it relies on the `needsToneMapping()` memo fallback — same as before my change (I preserved that fallback). Threading them into the per-rendition path (mirroring SV-1.6's `applySubtitleBurnIn` merge in `ensureSegment`) would let new ABR jobs also skip the per-segment re-derive; flagging as a possible follow-up, deliberately NOT done (beyond this sub-step's enumerated scope). ## Implementer — SV-1.1 sub-step (b′): thread tone-map flag+filter through the ABR rendition path — 2026-07-14 **Commit `0a738cbd`** (on `fcb74530`). phpstan L9 `-c phpstan.neon.dist` on changed files = 0 NEW errors (2 pre-existing errors in `TranscodeManagerTest.php` at the master-playlist + SV-4.2 tests — confirmed present on HEAD via `git stash`), phpcs PSR12 = 0 errors, `--filter 'Transcode|Ffmpeg'` = **237/237 green** (+4 new). NO caliber (standing directive; no pre-commit hook present anyway). ### ABR-gap claim: HELD (verified anchors at HEAD) - `ensureSegment` multi-variant branch = **:707-733**: `segmentParamsForRendition($rendition)` (**:719**) → `applySubtitleBurnIn` (**:731**). `segmentParamsForRendition` = **:1435** — a transcode rung returns `video_codec=libx264` + rung scale/level/VBV; a copy rung returns only `video_codec=copy,audio_codec=copy`. NEITHER carries `require_hdr_tone_map`/`tone_map_filter`. - Because the rendition params lack the flag+string, `FfmpegRunner::buildSegmentCommand` (**:1696**) fell into `elseif ($require_hdr_tone_map || $this->needsToneMapping($inputPath))` → `needsToneMapping()` (**:420**, calls `probe()`) + `getToneMappingProfile()` (**:485**, calls `probe()`) PER SEGMENT for HDR ABR playback (memo-saved probe, but decision+`extractColorMetadata`+`isHdrColorMeta`+filter recomputed every segment — exactly what SV-1.1 kills). Same for the hwaccel builder (**:2033-2042**). - The multi-variant job DOES persist the base `segment_params` JSON (INSERT **:552-561**, `$segParamsJson` from `computeSegmentParams` **:545**), which already carries `require_hdr_tone_map`+`tone_map_filter` from sub-step (b) — so the flag+string are available on `$row` to merge back in (same source `applySubtitleBurnIn` reads from). ### What was threaded + the round-trip 1. New **`TranscodeManager::applyToneMap(array $row, array $segParams): array`** (mirrors `applySubtitleBurnIn`): decodes `$row['segment_params']`; when it carries `require_hdr_tone_map === true`, sets `$segParams['require_hdr_tone_map']=true` and (when a non-empty string) `$segParams['tone_map_filter']`. When the base params lack the flag (pre-b′ job / un-rescanned / SDR), it merges nothing → legacy per-segment fallback preserved. 2. Called in `ensureSegment`'s **multi-variant branch** right before `applySubtitleBurnIn` (tone-map-before-burn-in conceptual order). Round-trip: `computeSegmentParams` resolves the filter ONCE (sub-step b, `resolveToneMapFilterFromProbe`) → persisted in `segment_params` JSON → `ensureSegment` reads `$row` → `applyToneMap` decodes+merges into the per-rendition `$segParams` → `produceSegment`→`startSegmentEncode`→builders use the threaded string DIRECTLY. NO second filter-building path created; NO scanner touch; NO migration. ### Byte-identity + SV-1.6 ordering (WHERE-computed, not WHAT-changed) - Same one resolved string for every rung: the tone-map graph is codec/color-driven (`buildZscale/LibplaceboToneMapFilter` ignore codec; the only codec branch is `prefer_hdr_output` + an HDR-capable codec, and every transcode rung is `libx264` — never HDR-capable, so never suppressed). HDR sources resolve to `libx264` in `computeHlsParams` (**:2600-2603**, HDR is 10-bit/non-h264) and `computeSegmentParams` upgrades any `copy`→`libx264` (**:1922-1929**) — the SAME final codec the base filter was resolved with. So threading the base string is byte-identical to the per-rung re-derive. Copy (`original`) rungs ignore it (buildSegmentCommand emits no `-vf` on the `-c:v copy` path) → merge inert there. - SV-1.6 ordering preserved on BOTH ABR builders: tone-map is `$filters[0]`, subtitle burn-in `[1]`, scale `[2]` (unchanged insertion order) — new tests pin tone-map-before-scale on the real rendition params. ### Tests (real numbers) - `TranscodeManagerTest` (+3): `testEnsureSegmentThreadsToneMapFilterForMultiVariantHdrJob` (HDR round-trip via `ensureSegment('seg-job','480p',2)` — captured `startSegmentEncode` params carry `require_hdr_tone_map`+`tone_map_filter`+`video_codec=libx264`; `needsToneMapping`/`getToneMappingProfile`/`resolveToneMapFilterFromProbe` asserted NEVER called on the produce path); `testEnsureSegmentOmitsToneMapForMultiVariantJobWithoutBaseFlag` (absent base flag → neither key injected → fallback preserved; mutation-red if unconditional inject); `testMultiVariantRenditionToneMapParamsBuildWithoutReDeriving` (REAL `segmentParamsForRendition` via reflection + tone-map merge → `buildSegmentCommand` emits the canonical string verbatim, tone-map before `scale=854:480`, ZERO probe/needsToneMapping/getToneMappingProfile via `ToneMapThreadingSpyRunner`). - `FfmpegRunnerToneMapThreadingTest` (+1): `testAbrRenditionHwaccelSegmentUsesThreadedFilterWithoutReDeriving` (same, for `buildHwaccelSegmentCommand` with nvenc seeded → verbatim string, tone-map before scale, zero re-derive). - `--filter 'Transcode|Ffmpeg'`: **OK (237 tests, 1130 assertions)**. phpcs adds 2 line-length WARNINGS — byte-identical `new SourceProfile(...)` lines copied from the file's existing ABR-test pattern (4+ identical pre-existing lines); 0 errors. ### SCOPE NOTE (still NEXT pass, not mine) - **Sub-step (a)** — read persisted `media_streams` color columns (mig 073) at `ensureHlsJob` to reach **0 HDR-probes** for scanned items (today still exactly 1 live probe at job creation) — remains OUT OF SCOPE. This sub-step (b′) only closed the per-segment ABR re-derive; the single job-creation probe is unchanged. ## Implementer — SV-1.1 sub-step (a): source the HDR tone-map decision from the persisted `media_streams` color columns — 2026-07-14 **Commit `ff0eec64`** (on `d481fe00`). Closes the perf-5 gap (worklog ~:2897): mig-073 color columns were WRITE-ONLY — the scanner wrote them but `computeHlsParams` always derived the HDR decision from a live probe. Now the decision (and the resolved `tone_map_filter`) is sourced from the persisted columns for scanned items, with a live-probe fallback for pre-073 / un-rescanned rows. NO scanner change, NO migration, NO (b)/(b′) threading change. NO caliber (standing directive). ### The read (ItemRepository) — verified anchors - New **`ItemRepository::getVideoStreamColorMetadata(string $mediaItemId): ?array`** (`src/Media/Library/ItemRepository.php`, placed right before `addStream`, after `getItemStreams`). Query (starts with SELECT): `SELECT color_space, color_transfer, color_primaries, max_luminance, avg_luminance FROM media_streams WHERE media_item_id = ? AND stream_type = 'video' ORDER BY stream_index LIMIT 1`. - `stream_type = 'video'` matches the scanner's tag (`MediaScanner.php:1571` `$isVideo = $codecType === 'video'`, persisted via `addStream` `stream_type`). `ORDER BY stream_index LIMIT 1` picks the FIRST video stream — same selection as `FfmpegRunner::extractColorMetadata()` (`FfmpegRunner.php:1381`, first video stream, defaults `bt2020nc/bt709/bt2020/1000.0/200.0`). - **Returns null** (→ probe fallback) when: no video-stream row, OR all three color-string columns are NULL (pre-073 / un-rescanned / ffprobe reported no color info — returning defaults there would look SDR and wash out genuine HDR). - **Byte-identity:** when populated, returns an `extractColorMetadata()`-shaped array applying the SAME per-field defaults for any individually-NULL column (`color_space ?? 'bt2020nc'`, `color_transfer ?? 'bt709'`, `color_primaries ?? 'bt2020'`, `max_luminance ?? 1000.0`, `avg_luminance ?? 200.0`). DECIMAL luminance strings cast to float. All 5 keys ALWAYS present → downstream reads stay guard-free (no `?? ''` → no phpstan L9 unreachable-branch). ### Where computeHlsParams now prefers columns (with fallback) - `TranscodeManager::ensureHlsJob` (`src/Media/Transcoding/TranscodeManager.php`): after `getMediaItem`, resolves `$persistedColorMeta = $this->persistedVideoColorMetadata($mediaItemId)` (new private helper — lazily `new ItemRepository($this->db)`, NO constructor/DI change → loads identically under index.php + start.php) and threads it into `computeSegmentParams(..., $persistedColorMeta)` → `computeHlsParams(..., $persistedColorMeta)` (both gained a trailing `?array $persistedColorMeta = null`). - HDR decision: `$colorMeta = $persistedColorMeta ?? $this->ffmpeg->extractColorMetadata($probe);` — columns when present (0 probes contributed), in-hand probe otherwise. The `require_hdr_tone_map` derivation (`isHdr` = `smpte2084`/`arib-std-b67` transfer; `isBt2020`) is unchanged, just fed column-sourced metadata. - Tone-map filter (`computeSegmentParams`, the sub-step-(b) resolution): when `$persistedColorMeta !== null` uses the NEW **`FfmpegRunner::resolveToneMapFilterFromColorMeta($persistedColorMeta, $videoCodec)`** (0 probes); else the pre-(a) `resolveToneMapFilterFromProbe($probe, $videoCodec)`. - `FfmpegRunner`: extracted `resolveToneMapFilterFromProbe`'s body into new public `resolveToneMapFilterFromColorMeta(?array $colorMeta, string $codec)`; `resolveToneMapFilterFromProbe` now delegates (`extractColorMetadata($probe)` then the colorMeta core). Behavior-preserving — (b)/(b′) public API + string output unchanged. ### Byte-identity confirmation - The tone-map graph is decided by `isHdrColorMeta()` + config (`tone_mapping_mode`/`prefer_hdr_output`) + codec — NOT by the specific color VALUES (`buildZscaleToneMapFilter` hardcodes the graph; `buildLibplaceboToneMapFilter` reads tags off the frame — both ignore `$colorMeta`). Columns are the same values `extractColorMetadata` reads from the probe for the same file, so a scanned HDR item yields the SAME `require_hdr_tone_map` AND the SAME `tone_map_filter` string as the probe path. Proven at the FfmpegRunner level: `resolveToneMapFilterFromColorMeta(hdrMeta,'libx264') === resolveToneMapFilterFromProbe(hdrProbe,'libx264')`. ### HONEST probe-count framing (NOT overclaimed) - Sub-step (a) makes the HDR *decision* column-sourced → **0 HDR-specific probes** for scanned items. It does **NOT** remove the single `ffmpeg->probe()` at `ensureHlsJob` (~:420) — that still runs for embedded subtitle/audio stream detection (`detectTextTracks`) regardless. So the **observable probe count per job stays at exactly 1**. Reaching a true 0 needs persisting subtitle/audio stream descriptors (a separate "S6" follow-up), OUT OF SCOPE here. Code comments + the `testEnsureHlsJobHdrDecisionFromColumnsAddsZeroProbes` test assert `probe()` == exactly 1 and `extractColorMetadata` == 0 on the column path. ### Tests (real numbers) - `ItemRepositoryTest` (+4): persisted color → shaped array (DECIMAL→float); populated row with individually-NULL columns → SAME extractColorMetadata defaults (byte-identity); no video row → null; all-NULL pre-073 row → null. - `TranscodeManagerTest` (+3): `testEnsureHlsJobSourcesHdrDecisionFromPersistedColorColumns` (HDR columns present + probe stub → `require_hdr_tone_map=true` sourced from columns, `extractColorMetadata`+`resolveToneMapFilterFromProbe` asserted NEVER called, `resolveToneMapFilterFromColorMeta` called once with the column-shaped meta + `libx264` → `tone_map_filter` == canon); `testEnsureHlsJobFallsBackToProbeColorWhenColumnsAbsent` (no columns → probe path, `resolveToneMapFilterFromColorMeta` NEVER called; mutation-red if column path taken when absent); `testEnsureHlsJobHdrDecisionFromColumnsAddsZeroProbes` (probe==1, extractColorMetadata==0 — the honest framing). `mockDb` gained an optional `array $colorRow = []` (existing 5-arg callers unaffected). - `FfmpegRunnerToneMappingTest` (+2): column vs probe entry points agree for HDR meta (canonical graph); SDR meta + null meta → null. - `stubColorMetadata()` intact; existing sub-step (b) HDR/SDR `ensureHlsJob` tests stay green (mockDb returns `[]` for `FROM media_streams` → `persistedColorMeta` null → probe path preserved). - `--filter 'Transcode|Ffmpeg|ItemRepository'`: **OK (403 tests, 1540 assertions)** (+9). phpstan L9 `-c phpstan.neon.dist` on ALL changed src = **[OK] No errors**; changed test files = 0 NEW errors (the 2 in `TranscodeManagerTest` at lines ~1958/2311 are the SAME pre-existing offsetAccess/unusedUse confirmed on HEAD via `git stash`). phpcs PSR12 = **0 errors** (line-length WARNINGS only, matching the files' established house style). ### SCOPE NOTE (follow-up, not this pass) - True **0 probes** per job needs persisting subtitle/audio stream descriptors so the single `ensureHlsJob` probe can be dropped — separate "S6" follow-up, deliberately NOT attempted here. - ABR per-rendition path already carries the flag+filter via sub-step (b′)'s `applyToneMap` from the persisted base `segment_params`; sub-step (a) only changes HOW that base decision is sourced (columns vs probe), so (b′) is unaffected. ## Reviewer (cumulative: SV-1.1 sub-steps b + b′ + a) — 2026-07-14 **NO FINDINGS** Reviewed the integrated result of `6c115e04` (b) + `0a738cbd` (b′) + `ff0eec64` (a) against the plan §2 SV-1.1 AC (lines 654-662) and the ten enumerated seams. Verified end-to-end, not just by reading claims: - **Byte-identity across all four paths (single vs ABR × column vs probe):** the tone-map graph is decided by `isHdrColorMeta` + config (`tone_mapping_mode`/`prefer_hdr_output`) + codec ONLY — `buildZscaleToneMapFilter` hardcodes the graph and `buildLibplaceboToneMapFilter` reads tags off the frame; both ignore the color VALUES (FfmpegRunner.php:623-635, 687-692). `resolveToneMapFilterFromProbe` delegates to `resolveToneMapFilterFromColorMeta` after `extractColorMetadata` (FfmpegRunner.php:517-523), so the two resolve entry points are provably equal for equivalent meta (asserted via `===` in `FfmpegRunnerToneMappingTest::testResolveToneMapFilterFromColorMetaMatchesProbeEntryPoint`). Codec passed is the FINAL post-copy→libx264 codec in every path: `computeSegmentParams` resolves with `paramString($params,'video_codec') ?? 'libx264'` after the copy→libx264 upgrade (TranscodeManager.php:1996-2029); ABR transcode rungs are all libx264 (`segmentParamsForRendition`:1526); copy/original rungs emit no `-vf` (`buildSegmentCommand` :1688-1692) so the merge is inert there. - **Threading chain composes:** `getVideoStreamColorMetadata` → `computeHlsParams` sets `require_hdr_tone_map` (TranscodeManager.php:2688-2695) → `computeSegmentParams` threads `tone_map_filter` → both persisted in the SHARED job INSERT `segment_params` column (:555-567) for single AND multi-variant jobs → `ensureSegment` multi-variant reads `$row['segment_params']` and `applyToneMap` decodes+merges (:744, :810-836) before `applySubtitleBurnIn` → builders consume the threaded string with zero re-derive (:1726-1728, :2056-2058). Single-variant reads `segment_params` directly (:756-768). No break in the chain. - **Fallback correctness:** `getVideoStreamColorMetadata` returns null for no-video-row and all-three-color- columns-NULL (ItemRepository.php:1436-1444), whereupon `computeHlsParams` falls back to `extractColorMetadata($probe)` (:2688). Per-field defaults (`bt2020nc`/`bt709`/`bt2020`/`1000.0`/`200.0`) match `extractColorMetadata` exactly (FfmpegRunner.php:1441-1453 vs ItemRepository.php:1447-1451) for every reachable input — the scanner's `stringOrNull` normalizes '' → NULL before persistence (MediaScanner.php:1594-1596, 1646-1649), so a NULL column maps to the same default an absent probe field does. - **isHdr decision parity:** `computeHlsParams` uses the identical predicate (`smpte2084`/`arib-std-b67` transfer + `bt2020`/`bt2020nc`/`bt2020_ncl`) as `FfmpegRunner::isHdrColorMeta` — same for column and probe sources. - **Column→colorMeta shape:** returns all 5 keys guard-free; DECIMAL luminance cast via `is_numeric ? (float) : default` (ItemRepository.php:1450-1451); phpstan L9 clean. - **`new ItemRepository($this->db)` per job:** ctor is a two-field assign (ItemRepository.php:108-112), runs once per job at `ensureHlsJob` (NOT per segment), uses the shared Connection. Per-job `new` is fine here; DI would not materially improve it. - **Honest probe count:** code comments (TranscodeManager.php:2685-2687) and `testEnsureHlsJobHdrDecisionFromColumnsAddsZeroProbes` assert `probe()` == exactly 1 (subtitle/audio detection) and `extractColorMetadata` == 0 on the column path. No "0 probes" overclaim. - **SV-1.6 ordering + SV-4.2 non-interference:** tone-map precedes subtitle burn-in precedes scale on both builders and both variant paths (FfmpegRunner.php:1726-1748, 2056-2091). SV-4.2 in-flight/waiter/reconcile machinery lives in `produceSegment`/`startSegmentEncode` and is untouched — `applyToneMap` only augments `$segParams` before `produceSegment`. - **Quality gates:** `php -l` clean ×3; phpstan L9 `-c phpstan.neon.dist` on the three changed src = `[OK] No errors`; phpcs PSR-12 = 0 errors (line-length warnings only, house style); targeted suite `112 tests, 362 assertions` green. New read query starts with SELECT, parameterized `[$mediaItemId]`, uses `$this->db->query` (no raw PDO); no new statics/globals/exit/die/blocking-sleep; coroutine-safe. - **Scope:** only in-scope `FfmpegRunner.php` + `TranscodeManager.php` + the `ItemRepository` read (the read-side realization of the plan's "scanner stream persistence" bullet) + tests touched. No scanner code changed and no migration added because migration 073 already shipped in a prior pass. No out-of-scope file touched. Non-blocking observation (verified benign, NOT a finding): `getVideoStreamColorMetadata` coerces an empty- string column to the per-field default (`!== ''` guard, ItemRepository.php:1429-1434), whereas `extractColorMetadata` preserves a literal `''`. The only case this could diverge (an HDR transfer paired with a literal-`''` color_space/primaries flipping `isBt2020`) is unreachable: the scanner's `stringOrNull` collapses `''` → NULL before persistence and real ffprobe emits `unknown`/omits rather than `''` for these tags. Mentioned for the record only. ## Test — SV-1.1 — 2026-07-14 **GREEN.** Validated the integrated SV-1.1 result (`6c115e04` b + `0a738cbd` b′ + `ff0eec64` a, HEAD `ad57b99d`). Added the AC's explicit probe-count SESSION test + closed the last per-method coverage gaps on the SV-1.1 methods. NO src changed (test-only pass); NO caliber (standing directive). ### FULL Unit suite (`./vendor/bin/phpunit --testsuite Unit`) — real output ``` ................................... 5342 / 5342 (100%) Time: 01:41.615, Memory: 132.50 MB OK, but some tests were skipped! Tests: 5342, Assertions: 40826, Skipped: 5. ``` - **5342 tests / 40826 assertions / 0 Failures / 0 Errors / 5 Skipped**, exit 0. - vs post-SV-4.2 baseline `da69c2e1` = 5316/0F/0E/5S → **+26** (SV-1.1 sub-steps added +22; this Test pass added +4). Same 5 pre-existing skips — no regression, no new red. ### Probe-count SESSION test (the AC mandate, lines 654-662) — ADDED No prior test simulated a WHOLE multi-segment session with a cumulative probe counter — the sub-steps' tests each asserted per-call (`testEnsureHlsJobHdrDecisionFromColumnsAddsZeroProbes` = job-creation only; `testMultiVariantRenditionToneMapParamsBuildWithoutReDeriving` = one ABR segment; the `FfmpegRunnerToneMapThreadingTest` builders = one segment each). So I ADDED `TranscodeManagerTest::testMultiSegmentPlaybackSessionMakesAtMostOneProbe` + a new PSR-4 call-counting spy `tests/Unit/Media/Transcoding/ToneMapSessionSpyRunner.php` (a fixed HDR HEVC-4K probe so the REAL `ensureHlsJob` runs; `startSegmentEncode()` drives the REAL `buildSegmentCommand` — where any re-derive lives — without spawning ffmpeg, publishing the segment so `produceSegment`'s poll resolves). - Drives ONE real `ensureHlsJob` (scanned HDR item, columns present) → **`probeCalls == 1`** (the sole permitted subtitle/audio-detection probe; HDR decision is column-sourced → 0), captures the persisted base `segment_params` (`require_hdr_tone_map` + `tone_map_filter` == canonical zscale graph), then round-trips it through **5 single-variant** `ensureSegment(null,i)` builds AND **5 ABR-rendition** builds (`480p×2, 720p, 1080p, 360p`, all libx264 transcode rungs via `segmentParamsForRendition` + `applyToneMap`). Final assertion: **`probeCalls == 1`, `needsToneMappingCalls == 0`, `getToneMappingProfileCalls == 0`** across the entire 10-segment session — i.e. ≤1 total probe, 0 per segment, NOT ~3/segment. - **Mutation-verified:** temporarily disabling the threaded-filter branch in `FfmpegRunner::buildSegmentCommand` (`if (false && …)`) turned it RED — `getToneMappingProfileCalls == 10` (one re-derive per segment: 5 single + 5 ABR), the exact storm the test guards. Reverted; src is byte-identical to HEAD (`git diff --stat -- src/` empty). ### Coverage on the SV-1.1 changed methods (PCOV clover, focused instrumentation) — near/at 100% | method | lines | % | |---|---|---| | `ItemRepository::getVideoStreamColorMetadata` | 25/25 | 100% | | `FfmpegRunner::resolveToneMapFilterFromColorMeta` | 15/15 | 100% | | `FfmpegRunner::resolveToneMapFilterFromProbe` | 4/4 | 100% | | `FfmpegRunner::isHdrColorMeta` | 5/5 | 100% | | `TranscodeManager::computeHlsParams` (column-vs-probe decision) | 49/49 | 100% | | `TranscodeManager::computeSegmentParams` (column-vs-probe decision) | 21/21 | 100% | | `TranscodeManager::applyToneMap` | 13/13 | 100% | | `TranscodeManager::persistedVideoColorMetadata` | 1/1 | 100% | | `FfmpegRunner::buildSegmentCommand` (tone-map branch) | 100% (method 65/69 = 94.2%) | | `FfmpegRunner::buildHwaccelSegmentCommand` (tone-map branch) | 100% (method 90/96 = 93.8%) | - Both builders' **SV-1.1 threaded tone-map branches are fully covered**; the residual uncovered lines are UNRELATED to SV-1.1 (copy-passthrough / audio-codec / encoder-preset branches — 1675/1686/1764/1779 and 1960/2002/2022/2113/2117/2123). - To reach 100% on the SV-1.1-owned methods I added 3 focused tests: `FfmpegRunnerToneMappingTest::testResolveToneMapFilterFromColorMetaHonoursConfigBranches` (the `prefer_hdr_output`+HDR-codec / `tone_mapping_mode=none` / `libplacebo` config branches — was 73.3%), `TranscodeManagerTest::testApplyToneMapLeavesParamsUntouchedForMissingOrMalformedBase` (missing / empty / non-JSON base guards — was 84.6%), `ItemRepositoryTest::testGetVideoStreamColorMetadataReturnsNullForNonArrayRow` (the defensive non-array-row guard — was 96%). - Not SV-1.1 targets, noted for honesty: `getToneMappingProfile` 0/1 (its lone line is the legacy delegation that needs a REAL ffprobe on a real file — byte-covered by the `resolveToneMapFilterFromProbe` tests) and `needsToneMapping` 3/4 (pre-existing probe-null branch). Neither is in the AC's target list. ### Static gates - **phpstan L9 (`-c phpstan.neon.dist`):** `[OK] No errors` on the new spy + `FfmpegRunnerToneMappingTest` + `ItemRepositoryTest`. `TranscodeManagerTest` reports exactly the **2 PRE-EXISTING** errors (`offsetAccess.notFound` at the master-playlist test :1958, `closure.unusedUse $captOut` at the SV-4.2 test — now :2441) — both in code I did not write, confirmed present on HEAD; my additions introduce ZERO new phpstan errors. - **phpcs PSR-12:** 0 errors on all touched files (only pre-existing >120-char line-length WARNINGS, the files' established house style; my additions add none). - `php -m | grep -E 'swoole|uv'` → both present. ### Files (all absolute) - ADDED `tests/Unit/Media/Transcoding/ToneMapSessionSpyRunner.php` - `tests/Unit/Media/Transcoding/TranscodeManagerTest.php` (+ session test, + applyToneMap-guard test) - `tests/Unit/Media/Transcoding/FfmpegRunnerToneMappingTest.php` (+ config-branch test) - `tests/Unit/Media/Library/ItemRepositoryTest.php` (+ non-array-row guard test) ## PHP 8.5 deprecation cleanup — curl_close()/imagedestroy() no-op removal (2026-07-18) - [x] DONE — removed all 16 `curl_close($ch)` (13 files) + 19 `imagedestroy(...)` (ArtworkStorage 9, AvatarStorage 5, PhotoController 5) standalone no-op call sites; both are no-ops since PHP 8.0 and E_DEPRECATED under PHP 8.5 (polluted live-box logs during TV-series metadata matching). Every site was a standalone statement with a sibling statement, so line-deletes kept all blocks valid; no value-context/sole-statement hazards. `finfo_close` explanatory comments left untouched. `php -l` clean on all 16 edited files; full Unit **5677/41775/0 fail/0 err/5 skip**; phpstan `[OK] No errors`; phpcs PSR-12 0/0. Commits `a4a6281c` (curl_close) + `ed426816` (imagedestroy), pushed to master. ## Logs page overhaul — server side - [x] DONE (2026-07-18) — Dropped the redundant `"[LEVEL] " . date('Y-m-d H:i:s.v') . " "` prefix hand-built into 37 Monolog message strings across 6 call-site files (HttpHandler 11, SimilarityWorker 8, MediaAssetWorker 8, PluginAutoUpdateWorker 4, BackgroundDetectorWorker 3, LibraryScanWorker 3). Monolog LineFormatter already emits `[] .: `, so the hand-built prefix doubled the level + timestamp on the admin Logs page; now every line is a clean single- level/single-timestamp record. `error_log()` sites (public/index.php, Router.php, ConnectionPool.php) left UNTOUCHED — they write to the PHP error log where the prefix is the only metadata. No test asserted the prefixed strings (none needed updating). php -l clean on all 6; Unit **5720/41855/0 fail/ 0 err/8 skip**; phpstan `[OK] No errors`; phpcs PSR-12 0 errors on src/ (reflowed the collapsed lines to stay <=120 and inlined round() to avoid multi-line-call indent). ## SV-3.3(1A) — thread loudness config to TranscodeManager ctor (inert until 1B) (2026-07-18) - [x] DONE — Plumbing only. Confirmed the config source: the investigation's `$appConfig['ffmpeg']` claim HELD — `TranscodeServicesProvider::register()` already reads `$ffmpegConfig = $appConfig['ffmpeg']` (:55), so `config/ffmpeg.php`'s `loudness` block is reachable there. Added a nullable ctor arg `?array $loudnormParams = null` at the END of `TranscodeManager::__construct` (position 14, after SV-1.9 `$minDiskSpaceBytes`) → stored in a `private readonly ?array $loudnormParams` + public `getLoudnormParams()` accessor (so it isn't write-only; consumed by 1B). All existing callers pass ≤12 positional args so BC preserved. Provider now reads `$ffmpegConfig['loudness']` and, ONLY when `enabled === true` AND `I` is numeric, normalizes to a float `['I'=>…,'LRA'?=>…,'TP'?=>…]` array (LRA/TP folded in when numeric) and threads it as arg 14; disabled/malformed → null. Built via the explicit `factory()` closure (not autowiring) so no PHP-DI optional-param landmine. INERT by default: `loudness.enabled` ships false → null → zero behavior change (deployable). +5 provider tests (absent, disabled, enabled full I/LRA/TP, partial I-only, enabled-but-missing/non-numeric-I → null) via reflection on the private property + the getter, mirroring the SV-1.9 provider test. Unit **5735/41879/0 fail/0 err/11 skip**; phpstan L9 `[OK] No errors`; phpcs PSR-12 0/0 on the two changed src files. **1B STILL NEEDS:** consume `getLoudnormParams()` to populate `$params['loudnorm']` at the three param-assembly sites — `computeSegmentParams`, the ABR rendition branch, and `produceAudioSegment` — so `FfmpegRunner::buildLoudnormFilter()` (:1906, already wired into buildSegmentCommand/ buildAudioSegmentCommand) actually receives targets. Files: `src/Media/Transcoding/TranscodeManager.php`, `src/Common/Container/Providers/TranscodeServicesProvider.php`, `tests/Unit/Common/Container/Providers/TranscodeServicesProviderTest.php`. ## SV-3.3(1B) — populate loudnorm params at all three segment-assembly sites (2026-07-18) - [x] DONE — Added private helper `TranscodeManager::applyLoudnorm(array $segParams): array` (mirrors `applyToneMap`/`applySubtitleBurnIn`; adds `$segParams['loudnorm'] = $this->loudnormParams` only when the 1A-threaded property is non-null → disabled stays byte-identical). Wired at ALL THREE sites: (1) `computeSegmentParams()` right after the copy→aac audio upgrade — its output persists to `segment_params`, which the LEGACY single-variant `ensureSegment()` reads straight back; (2) the ABR multi-variant branch of `ensureSegment()` after `applySubtitleBurnIn` (segmentParams are rebuilt fresh per-rung by `segmentParamsForRendition()`, so the merge-back is load-bearing for single-audio ABR video segments — real playback path); (3) `produceAudioSegment()`'s fresh `$segParams` (multi-audio audio-only segments — the ONLY place normalization can land since a multi-audio job's video segments are `-an`). `FfmpegRunner::buildLoudnormFilter()` + its buildSegmentCommand/buildAudioSegmentCommand wiring were already present from the earlier SV-3.3 code drop — 1B only populated the params. Tests (were ZERO): +13 `FfmpegRunnerLoudnormTest` (filter units: null when absent/non-array/missing-I/non-numeric-I; single-pass I / I:LRA:TP / measured 2nd-pass strings; copy-audio stays unfiltered; both command builders emit/omit `-af loudnorm`) and +7 `TranscodeManagerTest` (all three sites: enabled → captured params carry `loudnorm` AND the real builder emits `-af "loudnorm=I=-16:LRA=11:TP=-1.5"`; disabled → no key, command byte-clean — using a single-audio fixture for the ABR video rung and a **multi-audio** fixture for the audio-only path per the injection landmine).

Now it parses `X-Phlix-Client-Capabilities` via the SHARED `ClientCapabilities::fromJson()` (same idiom as `TranscodeController`) and, when `hasExplicitCapabilities()`, sets `direct_play = supportsCodec($defaultAudioCodec)`; absent/empty header → still `true` (backward compat preserved exactly). Default codec = new private `defaultAudioCodec()` helper (default-disposition track, else first, from `StreamTrackShaper::audioTracks`) — keys on the SAME first/default audio stream the transcode path's `TranscodeManager::computeHlsParams()` gates on, so playback-info and the transcode decision agree (no "direct-play OK then silent audio"). Docblock `$request` "(unused)" note fixed. **2B verdict: NOT NEEDED / skipped.** `direct_play`/`directPlay` is consumed by ZERO clients — grep of phlix-ui/src, phlix-contracts, phlix-shared and every native client (roku/mobile/tizen/ windows/console) source finds no reader; the SPA PlayerPage hits `/playback-info` (MediaItemController) only for markers/chapters/audio-tracks and streams from `/media/:id/stream` regardless. Adding a `direct_play` field to `MediaItemController::getPlaybackInfo` would be dead code → gold-plating, omitted.

Focus: seams between config→provider→ctor→applyLoudnorm→FfmpegRunner emit, and the playback-info↔transcode capability-gate consistency. 4 findings (1 real seam bug, 1 consistency/doc defect, 2 INFO/by-design). 1. **[MEDIUM — seam / missed 4th emit path] `src/Media/Transcoding/FfmpegRunner.php:2168-2179` (`buildHwaccelSegmentCommand` audio re-encode branch), reached via `startSegmentEncode` (`FfmpegRunner.php:2363-2364`).** 1B correctly seeds `$params['loudnorm']` at all THREE *param-assembly* sites in `TranscodeManager`, and `buildSegmentCommand` (`:1793-1797`) + `buildAudioSegmentCommand` (`:1867-1871`) emit `-af "loudnorm=…"`. But there is a FOURTH *emit* path: `buildHwaccelSegmentCommand` re-encodes inline audio to AAC (`-c:a aac -b:a …`) and NEVER calls `buildLoudnormFilter()`, so it drops the filter. `startSegmentEncode` prefers this builder whenever `hwaccel.enabled && prefer_hardware` — and `config/hwaccel_base.php` ships BOTH `true` by default. So on any deployment with a working hardware encoder, a **single-audio** job's video segment (inline audio, not `-an`) is loudness-normalized on the software path but silently NOT on the hwaccel path. This directly contradicts 1B's own `applyLoudnorm()` docblock ("every ABR video segment's audio re-encode is loudness-normalized … injecting at only one site would silently miss the others — the SV-3.3 landmine") and the SV-3.3 AC. Multi-audio jobs are safe (video segments are `-an`; audio flows through `buildAudioSegmentCommand`, which does emit loudnorm), so the gap is scoped to single-audio inline-audio jobs on GPU boxes. Latent today (loudness ships OFF; the current prod box has no GPU → software fallback), but it is a genuine correctness bug for the general/GPU case and is UNTESTED — `FfmpegRunnerLoudnormTest`/`TranscodeManagerTest` exercise only the software builders. **Fix:** in `buildHwaccelSegmentCommand`'s non-copy audio branch, append the same `buildLoudnormFilter()` `-af` block used by `buildSegmentCommand`; add a hwaccel command-integration test asserting the `-af loudnorm` string (and its absence when disabled). 2. **[LOW-MEDIUM — consistency + inaccurate docblock] direct_play verdict keys on a DIFFERENT audio stream than the transcode copy-vs-encode decision.** `WebPortalRouter::defaultAudioCodec()` (`src/Server/WebPortal/WebPortalRouter.php:1328`) selects the **default-disposition** audio track (else first) — deliberately, as `testDirectPlayGatesOnDefaultTrackNotFirstTrack` proves. But `TranscodeManager::computeHlsParams()` derives `$srcA` from `firstStreamOfType($probe,'audio')` (`TranscodeManager.php:2766,2769`) — the FIRST ffprobe audio stream, ignoring the `default` disposition — and gates copy-vs-transcode on that (`:2839-2845`). The `supportsCodec()` predicate is identical, but the STREAM SELECTION differs. For the common case (default == first audio) they agree; they disagree when the default audio track is not the first ffprobe stream AND the two tracks' codecs differ (e.g. first=aac non-default, default=eac3): playback-info reports `direct_play=false` on eac3 while the on-demand transcode path copies/maps the aac FIRST track (`-map 0:a:0?`). Impact is bounded (the client still receives playable audio), so this is minor — but both the `defaultAudioCodec()` docblock ("mirrors the first-audio-stream predicate the transcode path uses") and the 2A worklog entry ("keys on the SAME first/default audio stream … so playback-info and the transcode decision agree") OVERSTATE the consistency; the selection is not the same. **Fix:** either reconcile (have `computeHlsParams` prefer the default audio track too) or correct the docblock/worklog to state that direct_play gates on the *default* track while the transcode copy decision gates on the *first* track, and why the divergence is acceptable. 3. **[INFO — latent, currently dead] `src/Media/Transcoding/FfmpegRunner.php:2823` (`buildGaplessSegmentCommand`).** Same class of gap as finding 1: it re-encodes audio to AAC (`:2873-2879`) without emitting loudnorm. It has ZERO callers in `src/` today (grep confirms only docref mentions), so it is inert — but if it is ever wired into a playback path it would silently skip normalization. Worth a guard/comment when finding 1 is fixed. 4. **[INFO — by design, operator-facing] copy-audio and direct-play silently bypass loudnorm.** `buildLoudnormFilter` can only apply on a real encode, so when `audio_codec='copy'` (an aac source the client supports → the `original`/copy rung) or when a client DIRECT-PLAYS the source file, no normalization is applied — with no indication. `applyLoudnorm` acknowledges this and it is a correct inherent limitation (you cannot filter a copied stream). Not a bug, but an operator who enables loudness normalization may be surprised that aac-copy rungs and direct-play sessions are un-normalized; consider documenting this in `config/ffmpeg.php`'s `loudness` block. Non-findings verified: byte-identical-when-disabled holds (null → no `loudnorm` key → `buildLoudnormFilter` returns null → no `-af`); loudnorm filter values are `(float)`-cast and `is_numeric`-guarded end to end (no shell injection); `ClientCapabilities::fromJson` on absent/empty/garbage/non-object JSON → safe empty instance → `direct_play=true` (backward compat preserved, matching tests); `$loudnormParams` is a readonly ctor-set property (no resident-memory/static-state issue); 1B and 2A tests are genuine (assert real `-af "loudnorm=I=-16:LRA=11:TP=-1.5"` strings and real `direct_play` true/false flips, not decorative). PSR-12 / strict types / L9 clean on the changed surface. ### Fixer (cumulative SV-3.3) — 2026-07-18 — findings 1-4 RESOLVED - **1 [MEDIUM, fixed+tested]** `FfmpegRunner::buildHwaccelSegmentCommand` audio RE-ENCODE branch now emits `buildLoudnormFilter()` via `-af "loudnorm=…"` (mirrors the software builders; copy branch stays inert). loudnorm is an AUDIO filter, independent of the video `-vf`/hwupload chain — no collision. Tests: `FfmpegRunnerHwaccelTest` +4 (emit-on-reencode, omit-on-copy, coexist-with-`-vf`, hwaccel-preferred-still-normalizes). - **2 [LOW-MED, reconciled behavior]** chose to RECONCILE, not just doc-correct: `WebPortalRouter` `defaultAudioCodec()` → renamed `firstAudioCodec()`, now selects `$audioTracks[0]` (StreamTrackShaper sorts by `stream_index` asc, so `[0]` == `firstStreamOfType($probe,'audio')` that `computeHlsParams` uses) → verdict and transcode decision genuinely agree. Docblock + call-site comment corrected. Test `testDirectPlayGatesOnDefaultTrackNotFirstTrack` rewritten → `...OnFirstTrackNotDefaultTrack` (+ swapped-codec companion) to pin first-stream selection. - **3 [INFO, done]** `buildGaplessSegmentCommand` given the same re-encode-only `-af loudnorm` block (still zero callers); +3 lock-in tests in `FfmpegRunnerLoudnormTest`. - **4 [INFO, done]** `config/ffmpeg.php` `loudness` block gained an OPERATOR NOTE: loudnorm applies only to RE-ENCODED audio; copy-audio rungs (`original`) + direct-play bypass it by design. - Full Unit **5782 / 42039 assertions / 0 fail / 0 err / 5 skip** (baseline 5774 + 8 net new). phpstan L9 `[OK] No errors`; phpcs PSR-12 0/0 on `src/` + `config/ffmpeg.php`. ### Reviewer (cumulative SV-3.3 — confirming re-review of Fixer commits) — 2026-07-18 Re-reviewed the Fixer's two commits (`f39895d6` hwaccel+gapless loudnorm; `768e84de` direct_play first-audio reconciliation) against the 4 cumulative findings, verifying both correctness AND absence of a fix-introduced regression. **NO FINDINGS.** Verified: 1. **Hwaccel `-af` placement is safe.** Read `buildHwaccelSegmentCommand` in full at HEAD (`FfmpegRunner.php:1969-2201`): the added `-af "loudnorm=…"` sits in the audio RE-ENCODE branch (`:2188-2191`), output-side (well after `-i` at `:2044`), AFTER the video `-vf` chain (`:2158`). The hwaccel builder uses `-vf` only — never `-filter_complex` — so the audio filter graph cannot collide with the tone-map/scale/hwupload video graph. Emitted ONLY on the non-`copy` branch; `-c:a copy` stays inert. 2. **No regression when disabled.** The only added code is the `if ($loudnormFilter !== null)` guard; with loudness null/absent `buildLoudnormFilter()` returns null → no `-af` → the hwaccel and gapless commands are byte-identical to pre-fix. 3. **Finding-2 reconciliation is genuinely correct.** `StreamTrackShaper::audioTracks()` (`StreamTrackShaper.php:66-105`) iterates `sortedByStreamIndex()` (`:176-186`, a `usort` on `stream_index` ascending), so `$audioTracks[0]` is the lowest-`stream_index` audio stream. `TranscodeManager::firstStreamOfType($probe,'audio')` (`:3151-3164`) returns the first audio stream in ffprobe array order (index order). These select the same stream — `firstAudioCodec()` and `computeHlsParams`' copy-vs-encode decision now agree. Confirmed `$audioTracks` in `getPlaybackInfo` is that shaper output (`WebPortalRouter.php:1271,1291,1337`); no orphaned `defaultAudioCodec` references remain (grep clean). The still-emitted `default` field on each track is unused by the verdict but retained for the player menu — no regression. 4. **Tests are genuine.** `test_hwaccel_segment_loudnorm_coexists_with_video_filter` asserts `-vf "` + `scale=1280:720` present, `-af "loudnorm=I=-23:LRA=7:TP=-2"` present, and `assertDoesNotMatchRegularExpression('/-vf "[^"]*loudnorm/')` (loudnorm NOT folded into `-vf`). The flipped `testDirectPlayGatesOnFirstTrackNotDefaultTrack` + swapped-codec companion pin first-`stream_index` selection regardless of disposition. 5. Numeric guard intact (`buildLoudnormFilter` `is_numeric` + `(float)` casts, no injection); byte-identical-when-disabled holds across all FOUR re-encode builders. Ran the 3 affected test files: **37/37 pass (128 assertions)**. phpstan L9 `[OK] No errors`; phpcs PSR-12 clean on `FfmpegRunner.php`, `WebPortalRouter.php`, `config/ffmpeg.php`. ## Reviewer (cumulative) — 2026-07-18 Cumulative integration review of SV-4.15 (commits b343c3e0, 603ca375, 9d46eb47, 4d7b31a1, de990be6, 80e9f893, aaf6b688). Verdict: the DB backend, central 429 mapping, DI wiring, and WS no-throw seam are correct, but the **IP source that every IP-keyed surface depends on is client-spoofable in the shipped deployment**, which defeats the feature's headline goal. Findings: 1. **HIGH — IP-keyed limiters (register / refresh / jwks / webauthn IP-fallback) are trivially bypassable via a forged `X-Forwarded-For` header.** `Request::getClientIp()` (`src/Server/Http/Request.php:379-388`) returns `trim(explode(',', $xff)[0])` — the LEFTMOST XFF entry. The shipped reverse proxy sets `proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;` (`reverse-proxy/nginx/phlix.conf:72,88,113,127,149,177`), i.e. it APPENDS the real connecting IP to whatever XFF the client sent, leaving the client-forged value leftmost. (The WS HAProxy front is worse still: `http-request set-header X-Forwarded-For %[hdr(x-forwarded-for)]` in `deploy/haproxy.cfg` copies the client header verbatim.) An attacker who sends `X-Forwarded-For: ` on every request gets a fresh bucket each time, so `register:` (`AuthController.php:131`), `refresh:` (`AuthController.php:274`), `jwks:` (`HubJwksController.php:93`), and the WebAuthn IP fallback (`WebAuthnController.php:97`) never trip. This nullifies exactly the DB-backed "TRUE-global" register/refresh limiters that migration 085 + `DbRateLimiter` exist to provide — the feature is ineffective as shipped. Why it matters: the whole point of SV-4.15 is brute-force / enumeration throttling; a single header defeats it. Fix: derive the key from a TRUSTED source, not the leftmost XFF — e.g. prefer the proxy-set `X-Real-IP` (nginx sets it to `$remote_addr`, overwriting any client value: `phlix.conf:71,87,...`), OR parse XFF right-to-left past known trusted-proxy hops, OR use `$request->remoteIp` when the proxy overwrites XFF. Whatever is chosen must be a trusted-proxy-aware value; document the proxy contract it depends on. Amplifying consequences of the same spoofable key: (a) `DbRateLimiter` has NO hard row cap — `sweepExpired()` (`src/Common/RateLimit/DbRateLimiter.php:220-228`) only deletes rows whose `reset_at <= now`. A flood of distinct (spoofed) keys inserts rows that do not expire until the full window elapses, so `rate_limit_buckets` grows to ~(unique-keys × window) with nothing reclaimable in the first window — a disk/row-growth DoS the in-memory `RateLimiter` is immune to (it has `$cap` + eviction). Once IP keys are un-spoofable (per the fix) this is bounded by real client count and matches the `login_rate_limit` precedent; until then it is attacker-amplified. (b) `rate_key` is `VARCHAR(191)` PK (migration 085); a forged XFF whose first segment exceeds ~183 chars produces an over-length key → under `STRICT_TRANS_TABLES` the `hit()` INSERT throws "Data too long", which is NOT a `RateLimitException`, so it falls through to the generic HTTP 500 — a cheap error-injection vector on register/refresh. Clamp/validate the derived IP. 2. **MEDIUM — WS-connect limiter collapses all clients into ONE shared bucket behind the shipped proxies (self-DoS / over-block).** `onWebSocketConnect()` keys on `$connection->getRemoteIp()` (`src/Server/WebSocket/WebSocketServer.php:400-401`) — the TCP peer. The shipped deployment proxies the `:8097` worker (HAProxy `ws-external` → `127.0.0.1:8097` in `deploy/haproxy.cfg`; nginx `location /ws` → `phlix_backend` in `phlix.conf:106-119`) with NO PROXY-protocol, and the worker (`websocket://0.0.0.0:8097`, `start.php:479`) does not parse PROXY-protocol, so `getRemoteIp()` is the proxy's loopback address for EVERY client. With `ws_connect` max=30/60s, the 30th WebSocket handshake server-wide trips the limit and rejects ALL subsequent connections for the window — a functional availability regression, and the per-IP intent is lost (there is effectively no per-client throttle at all). Note this is the mirror of Finding 1: WS correctly uses the unspoofable TCP peer but, being behind a loopback proxy, that peer is useless; HTTP uses the spoofable header. Both need a single, correct, trusted-proxy-aware client-IP derivation. Fix: enable PROXY-protocol on the WS listener + proxies, or derive the WS client IP from the trusted XFF/X-Real-IP the upgrade request carries (consistent with the Finding-1 fix); verify against the shipped proxy config before shipping. 3. **LOW — WebAuthn per-username keying does not throttle horizontal enumeration.** `webauthn_start` / `webauthn_finish` key on the submitted username (IP only when username is absent — `WebAuthnController.php:90-97, 171-177, 206-212`). A spray attack (one attempt each across many usernames from one source) hits a fresh bucket per username and is never throttled. This protects a single account from being hammered but not the enumeration sweep the surface is otherwise meant to blunt. Consider an additional IP-scoped (composite `ip:username` or per-IP) limiter once a trusted IP source exists (Finding 1). 4. **LOW — the Workerman 429 path skips response decoration.** In `HttpHandler::__invoke` the `catch (RateLimitException $e)` (`src/Server/Workerman/HttpHandler.php:303-313`) sends `Application::rateLimitResponse($e)->toWorkermanResponse()` directly, bypassing the `$cors->decorate()`, `$securityHeaders->decorate()`, and `compressResponse()` applied on every other branch. A cross-origin XHR that hits the limit therefore gets a 429 with no CORS/security headers (the browser may not surface the `Retry-After`). Minor consistency gap; route the 429 through the same decoration path. Confirmed CORRECT (no action): - `DbRateLimiter::hit()` upsert window logic is right: `attempts = IF(reset_at<=now,1,attempts+1)`, `reset_at = IF(reset_at<=now,new,keep)`; both IF conditions read the pre-update `reset_at` (MySQL only substitutes updated values for columns already assigned earlier in the SET list, and `reset_at` is only assigned once). The post-upsert re-SELECT can only over-count under a race, never under-count. `sweepExpired` binds `LIMIT` as a native `int` const (CLEANUP_BATCH_SIZE), avoiding the `LIMIT '100'` 1064 quoting hazard; all placeholders are positional `?` (no hub `:param` leakage — a test asserts this). Migration 085 schema is sane (VARCHAR(191) utf8mb4-safe PK, `idx_reset_at`, IF NOT EXISTS idempotent). - Central 429 (c) is uniform and non-swallowing: `Application::dispatch()` has NO try/catch, so a controller throw propagates to the single `HttpHandler` catch; `Application::handleException()` and `public/index.php`'s `set_exception_handler` map the same `rateLimitResponse()` envelope (429 + `Retry-After` + `code=rate_limited`). This also fixes the latent login-limiter 500-on-trip. - Per-surface wiring hits BEFORE the work on every surface and throws on `limited` (HTTP) or inline-rejects (WS); keys are distinct per surface. DI binds each optional limiter EXPLICITLY to its `RateLimitProfiles` id (dodging PHP-DI's optional-param skip); JWKS profile registered in AuthServicesProvider resolves into HubServicesProvider (single merged container). Degraded no-container fallbacks pass null → no-op. - WS seam (h) is safe: inline reject before the auth gate, never throws out of the hook (would `stopAll()` the count=1 worker), plain TCP close before the 101 upgrade is the correct idiom, and the `start.php` injection is best-effort try/catch (a resolve failure leaves the listener working, unthrottled, not crashed). - In-memory `RateLimiter` is resident-safe: bounded `$cap` map with expired-sweep + soonest-expiry eviction, instance field (no static/global), no coroutine yield mid-mutation. - Tests are genuine (real over-limit transitions at `>= max`, window restart, per-key isolation, positional-param assertion, DI-wiring assertions), not decorative. Out of scope / pre-existing (noted, not counted): the `login` limiter keys on `AuthManager::getClientIp()` = `$_SERVER['REMOTE_ADDR']` (`AuthManager.php:365-369`), which is not reliably per-request under resident Workerman workers — unchanged by SV-4.15, which only newly maps its trip to 429. Findings: 4 (1 HIGH, 1 MEDIUM, 2 LOW). Priorities #1 (XFF spoofing) and #2 (WS shared bucket) block the feature being effective in the shipped deployment. ## Fixer (SV-4.15 cumulative review) — 2026-07-18 Findings 1-4 resolved. Full Unit suite **5888 tests / 0 failures / 0 errors / 5 skipped** (floor was 5857); phpstan L9 `[OK] No errors`; phpcs PSR-12 clean on all changed src/ + tests. - **Finding 1 [HIGH] — IP-keyed limiters spoofable via forged X-Forwarded-For:** RESOLVED. Added `Phlix\Common\Http\TrustedProxyResolver` (walks XFF RIGHT-TO-LEFT past trusted-proxy hops; default trusted set = LOOPBACK ONLY, matching the shipped nginx→127.0.0.1:8080 / HAProxy→127.0.0.1:8097 loopback front that APPENDS `$remote_addr` to XFF; `TRUSTED_PROXIES` env override; always returns a validated IP ≤45 chars so it can't overflow the VARCHAR(191) `rate_key` PK). Decision: **dedicated resolver** — new `Request::getTrustedClientIp()` routed at register/refresh/jwks/webauthn; left the raw `getClientIp()` intact (now doc-flagged untrusted) so its existing contract/test stays green. - **Finding 2 [MEDIUM] — WS-connect one-bucket collapse:** RESOLVED in code. The WS hook's `Workerman\Protocols\Http\Request` DOES expose the upgrade headers (`->header()`), so `onWebSocketConnect` now derives the client via the SAME `TrustedProxyResolver` from X-Forwarded-For/X-Real-IP (peer = loopback HAProxy). Distinct real clients now get distinct buckets. - **Finding 3 [LOW] — WebAuthn horizontal enumeration:** ACCEPTED TRADEOFF (documented in `WebAuthnController::limitIdentifier`): no secondary per-IP cap — at the tight 10/60s budget it would false-positive on NAT'd households; the account-scoped throttle + existing per-IP `login` limiter are judged sufficient for a low-value enumeration oracle. IP fallback now uses the trusted IP. - **Finding 4 [LOW] — 429 skips decoration:** RESOLVED. The Workerman `catch (RateLimitException)` now runs the 429 through the same CORS + security-header + gzip finalization as every other branch. OWED (infra / on-box, orchestrator sign-off list): (a) on-box verify that a rate-limited 429 carries CORS + `Retry-After` headers through the real nginx front; (b) on-box verify WS-connect throttling keys per real client behind HAProxy — the true fix for `getRemoteIp()` uselessness there is PROXY-protocol on :8097 (currently we rely on the trusted XFF/X-Real-IP the HAProxy front injects; enabling PROXY-protocol would also fix `getRemoteIp()` and the S2 metrics `remote_ip`). ## Reviewer (cumulative, confirming re-review of SV-4.15 Fixer commits `679b3717`+`148dd5b0`+`5ec926f5`) — 2026-07-18 READ-ONLY re-review of the security Fixer's resolution of cumulative findings 1-4. Verified the `TrustedProxyResolver`, `Request::getTrustedClientIp()`, the WS-connect keying, and the 429 decoration against the ACTUAL shipped topology (nginx `$proxy_add_x_forwarded_for` APPENDS `$remote_addr` rightmost — `phlix.conf:72,88,113,127,149,177`; HAProxy `option forwardfor` appends the real source rightmost — `haproxy.cfg:78`; both fronts reach Phlix over a loopback peer). Confirmed Workerman's `parseHeaders()` comma-joins duplicate `X-Forwarded-For` lines (real client stays rightmost), so the two-line HAProxy case is handled identically to the single comma-joined nginx case. **Verdict: NO FINDINGS.** The HIGH bypass is genuinely closed and the resolver's fallback is never attacker-controllable in the shipped topology. Adversarial cases reasoned through against the real topology — all safe: 1. XFF filled entirely with forged values (many hops) → nginx appends the real client rightmost; the right-to-left walk returns it on the FIRST iteration; forged values sit left and are never reached. 2. Forged entries disguised as loopback/trusted IPs → still left of the appended real client; the walk stops at the first untrusted-from-the-right = the real client. An attacker cannot place any value to the RIGHT of nginx/HAProxy's appended `$remote_addr` (it is always concatenated last). 3. ALL entries trusted (attacker floods XFF with loopback) → walk finds no untrusted hop → falls to `X-Real-IP` (nginx overwrites via `set_header`, unspoofable) → else the loopback PEER. The fallback is a FIXED safe value (`127.0.0.1`), collapsing such attackers into ONE bucket (more restrictive, not a bypass) — never an attacker-chosen value. In the real topology this branch is unreachable because the appended real client is a public (untrusted) IP. 4. Empty/whitespace XFF, empty inter-comma entries, non-IP tokens → empty entries `continue`d, a non-IP token `break`s the walk (stops trusting further-left client data); rightmost appended real client (always a valid IP) is returned before any break can fire. Falls through safely to X-Real-IP/peer. 5. `X-Real-IP` on the HAProxy path is client-spoofable (HAProxy doesn't overwrite it), but it is UNREACHABLE there: `option forwardfor` always appends the real external client as an untrusted rightmost XFF hop, so the walk returns before the X-Real-IP fallback is consulted. Point-by-point on the review bar: - **CIDR matcher (`ipMatches`):** correct. `127.0.0.1 ∈ 127.0.0.0/8`, `::1 ∈ ::1/128`, non-loopback excluded, family-mismatch (4 vs 16 bytes) → false, malformed bits (`ctype_digit`) → false, `bits=0` → true, mask precedence `(0xFF << (8-r)) & 0xFF` correct (`<<`/`-` bind tighter than `&`). 13 data cases in `TrustedProxyResolverTest::cidrCases` cover the boundaries. - **Default trusted set (loopback only):** correct for this loopback-proxy deployment. RFC1918 correctly EXCLUDED (adding it would skip a LAN client as a "proxy" and re-expose the forged hop — the class docblock explains this). The real client never legitimately appears as loopback externally. - **Key-length/overflow:** `resolve()` always returns a `filter_var`-validated IP (≤45) or a `substr(...,0,45)` peer fallback — max fragment 45 chars; longest key `ws_connect:` (11) + 45 = 56 « 191. Proven by `testOversizedForwardedValueCannotOverflowKey` (5000-char XFF → `register:127.0.0.1`) and `testMalformedOrOversizedValueCannotOverflow`. - **WS keying (F2):** `upgradeHeader()` reads the lowercase header via Workerman `Request::header()` and coerces non-string → null defensively; peer (HAProxy loopback) is trusted so the walk reaches the real client; resolver is cached per-worker (immutable config, no request state); `resolve()` has no throw path and the hook still rejects via remove+close+return, never throwing out of `onWebSocketConnect`. `testDistinctRealClientsBehindLoopbackProxyGetDistinctBuckets` + `testLoopbackProxyDerivesClientFromForwardedFor` prove distinct real clients get distinct buckets and the forged leftmost is ignored. nginx `/ws` (`phlix.conf:106-119`) also appends rightmost + sets `X-Real-IP`, so both WS fronts are covered. - **No collateral:** raw `getClientIp()` body is unchanged (docblock-only edit) and has ZERO remaining security callers in `src/`/`public/`/`start.php` (grep clean; `AuthManager::getClientIp()` is a separate `$_SERVER` method, the pre-existing out-of-scope item). Only the rate-limit keys switched to `getTrustedClientIp()`. - **F4 429 decoration:** `$request` is declared `null` before the try and assigned at the top of the try; the `catch (RateLimitException)` CORS-decorates only under `$request instanceof Request` (no NPE if a throw beat the assignment), then applies `SecurityHeaders` + `compressResponse` (a no-op on the ~48-byte 429 body, below `GZIP_MIN_BYTES` — harmless) and sends exactly once; `$responseStatus=429` is set for the finally log. `testRateLimited429CarriesCorsAndSecurityHeaders` asserts the allowlisted Origin echo (never `*`) + `nosniff` on the 429. No other branch regressed. - **F3 (WebAuthn horizontal enumeration):** documented accepted tradeoff in `limitIdentifier()`; IP fallback now uses the trusted IP. Consistent with the finding's LOW disposition. Static/tests: the 7 SV-4.15 test files run GREEN (57 tests / 158 assertions); `php -l` clean; phpstan L9 `[OK] No errors` on all four changed src files (`TrustedProxyResolver`, `Request`, `WebSocketServer`, `HttpHandler`). Non-blocking notes (NOT findings, no Fixer loop): (a) a LOCAL attacker already connecting over the loopback peer could get a trusted rightmost hop skipped and spoof the bucket key — the inherent, documented loopback-trust tradeoff, well outside the rate-limiter threat model and unchanged by this fix; (b) the HTTP path builds a fresh `TrustedProxyResolver` (one `getenv`) per request vs the WS path's per-worker cache — a micro-inefficiency, not a defect (no static/global accumulation). The Fixer's OWED on-box items (real-nginx 429 CORS echo, HAProxy WS per-client throttle / PROXY-protocol) remain infra verification for orchestrator sign-off and are not code findings. NO FINDINGS. ## Scribe — 2026-07-18 Documentation sweep for this session's shipped work (PHP 8.5 cleanup, Logs prefix, SV-1.9 ENOSPC config, SV-3.3 loudness + capability negotiation, SV-4.15 per-surface auth rate limiting) + SV-4.7 status bookkeeping. Docs/comments only; no behavioral code changed. Files updated: - `/home/sites/phlix/phlix-server/CHANGELOG.md` — `[Unreleased]` gains Security (SV-4.15 rate limiting, 429+Retry-After, `rate_limit`/`trusted_proxies` config, migration 085, login 500→429 fix), Added (SV-3.3 loudness + `X-Phlix-Client-Capabilities`; SV-1.9 `hls.min_disk_space_bytes`), Fixed (PHP 8.5 `curl_close`/`imagedestroy` no-op removal; Logs `[LEVEL] datetime` prefix drop; Router HEAD fallback), and Changed (SV-0.6/0.7/1.8/1.9/4.8/4.12 test hardening). - `/home/sites/phlix/phlix-server/README.md` — new "Environment variables" table under Configuration (`HLS_MIN_DISK_SPACE_BYTES`, `RATE_LIMIT__MAX/_WINDOW`, `TRUSTED_PROXIES`) + rate-limit/ loudness/migration-085 notes; API Reference note on 429 rate limiting + `X-Phlix-Client-Capabilities`. - `/home/sites/phlix/phlix-server/performance_worklog_server.md` — SV-4.7 Progress flipped `[ ]`→`[x]` (done fecd0ab5, reviewed NO FINDINGS, on-box verified :8097). - `/home/sites/phlix/phlix-docs/docs/reference/env-vars.md` — new "Auth rate limiting (SV-4.15)" + "HLS / segment cache" sections. - `/home/sites/phlix/phlix-docs/docs/reference/config-files.md` — `hls.min_disk_space_bytes`; new "Rate limiting (SV-4.15)" (server.php) + "Loudness normalization (SV-3.3)" (ffmpeg.php) subsections. - `/home/sites/phlix/phlix-docs/docs/security/hardening.md` — new §11 "Auth rate limiting (built-in)" + `TRUSTED_PROXIES`/`RATE_LIMIT_*` rows in the quick-reference table. - `/home/sites/phlix/phlix-docs/docs/advanced/reverse-proxy.md` — corrected stale `TRUSTED_PROXY`→ `TRUSTED_PROXIES` env name; added the rate-limit client-IP keying requirement. - `/home/sites/phlix/phlix-docs/docs/player/player-quality-audio.md` — new "Client Capability Negotiation" + "Loudness Normalization" sections. - `/home/sites/phlix/phlix-docs/docs/reference/api.md` — 429 note under Auth Endpoints; `X-Phlix-Client-Capabilities` note under Transcoding Endpoints. Also (non-repo, no commit): `/home/sites/phlix/performance_plan.md` SV-4.7 corrected from NOT-DONE to DONE in §2 spec bullet + the two perf-2 resume-state notes + the perf-3 on-box-verify note. Owed on-box items remain infra verification (not docs): real-nginx 429 CORS echo, HAProxy WS per-client throttle / PROXY-protocol — noted honestly in the worklog, not claimed as done. ## install.sh env (2026-07-18) — TRUSTED_PROXIES + DB_* keys + optional tunables `scripts/install.sh` env-file management updated (fresh heredoc + `--update` backfill), idempotent: - SV-4.15 `TRUSTED_PROXIES`: documented commented block in the fresh heredoc (uncommented only when the `--no-proxy` interactive prompt supplies a non-loopback proxy IP/CIDR; non-interactive `--no-proxy` warns); `--update` appends the commented guidance block only when no `TRUSTED_PROXIES=` line (commented or not) exists (grep-guarded, preserves operator value). No forced default (matches the code's loopback-only default `127.0.0.0/8,::1/128`). - DB_* alias bug fix: heredoc now emits the keys `config/database.php` actually reads (`DB_HOST/DB_PORT/DB_NAME/DB_USER` alongside `DB_PASSWORD`), keeping the `PHLIX_DATABASE_*` aliases (uninstaller reads them). `--update` backfills each `DB_*` from the recorded `PHLIX_DATABASE_*` via `phlix_ensure_env_key` (no-op when operator already set it) — fixes custom `--db-*` installs silently hitting the default DB. - Optional tunables (commented, documentary only): `#HLS_MIN_DISK_SPACE_BYTES=524288000` + `#RATE_LIMIT__MAX/_WINDOW` for register/refresh/webauthn_start/webauthn_finish/jwks/ws_connect. Verified: `bash -n` clean; heredoc + backfill rendered/tested for both TRUSTED_PROXIES cases and run twice (no duplicate lines). Hub install.sh untouched (audit confirmed no change needed). --- ## Implementer — 2026-07-18 — §6 removal Run B: dead server gapless/crossfade subsystem (user-approved Tier 1 + Tier 2) Gapless + crossfade are implemented 100% client-side (phlix-ui `useMusicPlayer.ts`; UI-3.6 + SV-3.2). The server gapless subsystem was confirmed dead. Re-confirmed ZERO callers for every item via `git grep` across `src/` + `tests/` + `start.php` + `public/index.php` + `config/` (incl. `::class`/ string/`{@see}` refs) BEFORE deleting. No live caller was found for any item. Removed: 1. `FfmpegRunner::buildGaplessSegmentCommand()` + its docblock (was ~:2795-2893). No private helper became orphaned (it used only shared `self::seconds/paramString/paramInt/browserSafeVideoFlags` + `$this->buildLoudnormFilter`, all still used by the live builders). The FfmpegRunner class-docblock has no `@see` to it (only the ffmpeg.org URL) — nothing to change there; the `{@see …buildGaplessSegmentCommand()}` ref actually lived at `FfmpegRunnerLoudnormTest.php:15` and was updated. Removed its 3 unit tests (`testGaplessSegmentCommand{EmitsLoudnormOnAudioReencode,CannotFilterCopiedAudio,OmitsLoudnormWhenTargetAbsent}`) + their section comment; KEPT the `buildSegmentCommand`/`buildAudioSegmentCommand`/`buildLoudnormFilter` loudnorm tests (live paths). 2. Deleted `src/Media/Transcoding/GaplessTranscoder.php` (whole file; 0 callers). 3. Deleted `src/Media/Transcoding/CrossfadeGenerator.php` (whole file; only inbound ref was a `@see` in GaplessTranscoder, also deleted, + the trimmed GaplessPlaybackManager). 4. Deleted `src/Media/Playback/GaplessPlayer.php` (whole file; 0 callers after the manager trim). Trimmed (class KEPT — `getPreferences()` is LIVE, called by `MediaItemController:280`): 5. `src/Media/Playback/GaplessPlaybackManager.php` — removed `getPlayer()`, `getCrossfadeGenerator()`, `buildCrossfadeCommand()`, `isCrossfadeEnabled()`, `isGaplessEnabled()`, `clearPlayer()` (all re-confirmed zero external callers — the `isCrossfadeEnabled` grep hits were `PlaybackPreferences::isCrossfadeEnabled()`, a different live class). Removed the now-unused `$players`/`$crossfadeGenerator`/`$ffmpegRunner` fields + `CrossfadeGenerator`/`FfmpegRunner` imports. Constructor is now `__construct(?UserRepository)`. KEPT `getPreferences()`, its `$preferencesCache`, and `clearCache()`. Updated the class docblock. DI cleanup (DUAL-ENTRYPOINT — both entrypoints route controller construction through `Application.php` + the `MediaServicesProvider` container; neither `start.php` nor `public/index.php` constructs the manager directly, confirmed by grep): 6. `MediaServicesProvider.php:673` — dropped the `ffmpegRunner` `->constructorParameter(...)` (kept `userRepository`; kept the `FfmpegRunner` import — still used at lines 304/584). `Application.php` no-container branch (~:3001) — `new GaplessPlaybackManager(null)`; removed the now-dead `FfmpegRunner` creation (`loadFfmpegConfig`/`new FfmpegRunner`/`setConfig`) that fed only this manager (`loadFfmpegConfig` still used elsewhere in the class). Container branch — removed the now-dead `$ffmpegRunner = $this->container->get(FfmpegRunner::class)` fetch (unused; manager is resolved from the container). The 3 mock-based tests (`MediaItemControllerTest`, `MediaItemControllerParentalTest`, `PlaybackInfoTracksParityTest`) use `createMock(GaplessPlaybackManager::class)` (no real ctor) — stay valid, no change. No `GaplessPlaybackManagerTest` / `GaplessPlayerTest` / `CrossfadeGeneratorTest` / `GaplessTranscoderTest` files exist. Also: `PlaybackPreferences.php` docblock prose "into the GaplessPlayer" reworded to reference the kept `GaplessPlaybackManager::getPreferences()` (GaplessPlayer deleted). Verification: `phpstan analyze -c phpstan.neon.dist` → No errors (660 files). Targeted `phpunit --filter 'Gapless|Crossfade|FfmpegRunnerLoudnorm|MediaItemController|PlaybackInfoTracksParity'` → OK (43 tests, 229 assertions). `phpcs --standard=PSR12` on all 6 changed files → exit 0 (no violations). Final grep for `buildGaplessSegmentCommand|GaplessTranscoder|CrossfadeGenerator|GaplessPlayer\b|getCrossfadeGenerator|buildCrossfadeCommand` across `src/` + `tests/` + entrypoints + `config/` → ZERO hits. `GaplessPlaybackManager` (class kept) still referenced legitimately by the provider/Application/MediaItemController/3 mock tests. The only whole-repo hits for the deleted symbols are historical notes in THIS worklog (documentary, left as-is). Git: per the Implementer CARDINAL RULES (Phase Coordinator owns the git cycle — no push/merge from the implementer), the tree is left STAGED, not committed/pushed. Files: M `src/Common/Container/Providers/MediaServicesProvider.php`, M `src/Media/Playback/GaplessPlaybackManager.php`, M `src/Media/Playback/PlaybackPreferences.php`, M `src/Media/Transcoding/FfmpegRunner.php`, M `src/Server/Core/Application.php`, M `tests/Unit/Media/Transcoding/FfmpegRunnerLoudnormTest.php`, D `src/Media/Playback/GaplessPlayer.php`, D `src/Media/Transcoding/CrossfadeGenerator.php`, D `src/Media/Transcoding/GaplessTranscoder.php` (+ this worklog). Suggested commit message: `transcode/music: SV-6 remove dead server gapless subsystem (client-side impl superseded it)`. --- ## Reviewer (cumulative) — 2026-07-18 Seam/cumulative review of commit range `d21dc123..2c68da14` (§6 removals Run A `190445c7` + gapless removal `d781d155` + item5a `7e8854b8` + item5+ `882a8f06` + item5b `cac8c878` + item5c3 `f645edbc` + pin bump `2c68da14`). Focus: integration between the pieces and regressions the per-piece reviews could not see. Verified clean (no findings): Run A removals — zero dangling refs to `killSegmentProcess`, `HwaccelCommandBuilder`/`createCommandBuilder`, `dispatchAsync`/`sendToWebhookWithBackoff`, `ArtworkController`, `RequestContext::clearUserId/hasProfileId/clearProfileId`; kept `WebhookDispatcher::computeBackoffDelayMs`/`getHttpClient`/`BACKOFF_*_DELAY_MS` still have live callers (`dispatch()`→`sendToWebhook()`:284/317); test substitutions `clearUserId()`→`setUserId(null)` are behavior-preserving. Gapless DI (`d781d155`) — EVERY construction site consistent: no-container branch `Application.php:2992 new GaplessPlaybackManager(null)`, container branch `:3009 ->get(...)`, `MediaServicesProvider:673` dropped the `ffmpegRunner` param, tests use `createMock` (no ctor); `MediaItemController` never took `FfmpegRunner`, so the removed `$ffmpegRunner` fetch was genuinely unused; `getPreferences()` is self-contained (only `$userRepository`/`$preferencesCache`); the `FfmpegRunner` import in the provider is still used at 304/584. Logger routing (`cac8c878`) — app.log (`file`) and error.log (`error`) have no `channels`/`env` gate → still attach to EVERY channel (no coverage loss); events.log correctly scoped to EVENTS + gated on `PHLIX_DEBUG_EVENTS`; plugins.log scoped to PLUGINS; `handlerEnvEnabled()` truthiness (`1/true/yes/on`, `getenv===false`→false) is byte-identical to `EventDispatcherFactory::debugEnabled()`; `$this->channel` is the exact string `LoggerFactory::get()` was keyed with, and the per-channel cache means no cross-channel handler bleed; no record now routes nowhere (file handler catches all). item5c3 (`f645edbc`, HIGHEST SCRUTINY) — SEAM CONFIRMED SAFE: each `onWorkerStart` builds its OWN `ContainerFactory::create()` container, and `OrderedListenerProvider` is a per-container singleton shared by both `ListenerRegistry` and the PSR-14 dispatcher (`EventServicesProvider:94-123`), so bootstrap-attached listeners genuinely receive dispatched events; `bootstrapEnabled()` is idempotent per-process via the `entryInstances[$name]` guard in `enable()` (short-circuits BEFORE `container->get`/`subscribe`/`setEnabled`); the SV-3.6a pull timer uses `getEntryInstance()` which builds a FRESH instance and NEVER calls `onEnable()`/ `subscribe()` (`PluginLoader.php:704`), so it is orthogonal — no double-attach; `TraktPlugin::onEnable()` does NO listener subscription and NO network I/O (only container fetches + `initApi()` client build), so per-worker boot cost is bounded; HTTP and relay workers are SEPARATE processes with SEPARATE dispatchers and a given playback request is served by exactly one of them, so no same-event double-fire across workers; `index.php` correctly skipped (throwaway per-request container); the new test dispatches a real `PlaybackStarted` through the real provider after a double `bootstrapEnabled()` and proves exactly-once. Pin bump `2c68da14` trivial/correct. ### Findings 1. **[Medium] `src/Server/WebSocket/WebSocketServer.php` onClose:543-549 + touchActiveConnections:566-578 (regression introduced by `882a8f06`, surfacing via `src/Stats/Metrics/MetricsRegistry.php:270-284`).** Moving `openConnection()` out of `onConnect()` and into `onWebSocketConnect()` leaves a lifecycle gap for TCP connections that fire `onConnect` (which still adds the wrapper to the pool at :340) but never complete the WebSocket handshake — bare-TCP health checks (HAProxy fronts :8097 per the commit's own note), port scanners, and aborted/failed handshakes. For those, `onWebSocketConnect` (and thus `openConnection`) never runs, but `onClose()` still fires with the wrapper present and calls `$this->metrics->touchConnection(...)`; likewise the periodic `touchActiveConnections()` timer (armed every ~`intdiv(flush,2)`≈2s in `start.php:602-608`) touches every pooled-but-not-yet-opened connection. `MetricsRegistry::touchConnection()` has an `!isset($this->connections[$id])` fallback that INVENTS a row with `kind => 'http'` and `remote_ip => null` (:274-283). Net effect: every non-upgraded connection to the WS port now produces a phantom row mislabeled `http` with a null IP, flushed to `metrics_connections` under the WS worker's namespaced `worker_id` (10000+) — corrupting the http-vs-websocket breakdown and injecting null-IP rows. BEFORE this commit, `onConnect` always opened a correctly-kinded `websocket` record, so this class of phantom row did not exist. Why it matters: it is exactly the "is there now a window where a connection isn't tracked / is mistracked?" seam gap; the new `WsMetricsRemoteIpTest::testOnConnectAloneDoesNotRecordConnection` stops at `onConnect` and never exercises the subsequent `onClose`/touch path, so the regression is unverified. Suggested fix: have the WS server only touch connections it actually opened — e.g. track opened IDs (or an "upgraded" flag on the `Connection` wrapper) and skip `touchConnection()` in both `onClose()` and `touchActiveConnections()` for connections that never reached `onWebSocketConnect`; do NOT broaden `MetricsRegistry::touchConnection()`'s `!isset` fallback removal, since that branch is intentionally relied on by the HTTP dispatch path (touch-before-open). 2. **[Low] `src/Media/Playback/GaplessPlaybackManager.php:103-110` — `clearCache()` retained with zero callers (`d781d155`).** The gapless removal commit trimmed the class to `getPreferences()` + `clearCache()`, but `clearCache()` has no caller anywhere in `src/` or `tests/` (the many `clearCache` grep hits belong to unrelated classes: GuideManager, HlsSegmentPrefetcher, MetadataHttpClient, UserRepository, etc.). It is pre-existing dead code that a dead-code-removal commit chose to keep. Why it matters: minor completeness gap for a §6 cleanup; harmless at runtime and defensible as a cache-management companion to `$preferencesCache`, so this is informational — either drop it, or leave it deliberately with a note. No other integration/seam/boot-safety issues found across the range. --- ## Fixer — 2026-07-18 (cumulative findings 1 & 2) Both cumulative-review findings fixed, tests added, verified, committed. ### Finding 1 [Medium] — WS metrics phantom-row for never-upgraded connections — FIXED `M src/Server/WebSocket/WebSocketServer.php`. - Added a per-worker `private array $openedConnectionIds = []` (`array`), bounded by live connections (added on open, removed on close/reject — mirrors the ConnectionPool lifecycle; instance property, not static/global). - `onWebSocketConnect()`: after the existing `$this->metrics->openConnection(...)` call (inside the `if ($this->metrics !== null)` block) the id is recorded: `$this->openedConnectionIds[$id] = true`. This is the ONLY place an id is marked opened, so bare-TCP peers that never reach the handshake are never marked. - Both reject paths in `onWebSocketConnect()` (SV-4.15(h) rate-limit trip AND the auth-fail reject) `unset($this->openedConnectionIds[$id])` right after their existing `connections->remove($id)` — the pool wrapper is gone so `onClose` can't reap the tracking entry, so we drop it there to keep the set bounded. - `onClose()`: the final `touchConnection()` is now gated on `$this->metrics !== null && isset($this->openedConnectionIds[$id])`, and the id is `unset()` afterward regardless. A never-upgraded pooled connection (wrapper still present) is thus NOT touched → no phantom `kind=http`/`remote_ip=null` row. (`onClose` deliberately does NOT call `closeConnection()` — that behavior is preserved.) - `touchActiveConnections()` timer: `continue`s past any pooled connection whose id is not in `openedConnectionIds`, so the ~2s timer never fabricates a phantom row for a not-yet/never-upgraded connection. - Did NOT touch `MetricsRegistry::touchConnection()`'s `!isset` fallback (relied on by the HTTP touch-before-open path), nor the rate-limiter/connection-pool lifecycle — only the metrics calls are gated. `MetricsCollector::closeConnection()` is never invoked from `WebSocketServer`, so there was no `closeConnection` call to guard (onClose only touches). - Normal path verified intact: an upgraded connection still opens with the resolved client IP, is touched by the timer (cumulative bytes land in the registry), and records a final touch on close without deleting the row. ### Finding 2 [Low] — dead `GaplessPlaybackManager::clearCache()` — REMOVED `M src/Media/Playback/GaplessPlaybackManager.php`. Re-confirmed zero callers with `git grep -n 'clearCache' src/ tests/` — the only `GaplessPlaybackManager` hit was the definition itself (line 103); every other hit belongs to an unrelated class (UserRepository, GuideManager, HlsSegmentPrefetcher, LibraryManager, MetadataHttpClient, HwaccelProbe, LdapConnection). Removed the method; kept `getPreferences()` and the `$preferencesCache` field (still read+written inside `getPreferences()`). ### Tests - `M tests/Unit/Server/WebSocket/WsMetricsRemoteIpTest.php`: added `testNeverUpgradedConnectionCreatesNoPhantomMetricsRow` (onConnect → touch-timer tick → onClose, all assert `snapshotConnections()` stays empty — no phantom row) and `testUpgradedConnectionIsTouchedByTimerThenFinalTouchedOnClose` (normal path: open → timer records 1234/5678 cumulative bytes → onClose leaves the row). Existing upgraded-path assertions kept green. - `M tests/Unit/Server/WebSocket/WebSocketServerTest.php`: `testTouchActiveConnectionsRecordsLiveConnectionBytes` updated to drive the real lifecycle (onConnect + onWebSocketConnect) before the timer tick, since the timer now only touches connections it actually opened (the old test added a bare wrapper directly to the pool — exactly the never-upgraded case now correctly skipped). ### Verification - `./vendor/bin/phpstan analyze -c phpstan.neon.dist` → `[OK] No errors` (660 files). - `./vendor/bin/phpunit --filter 'WebSocket|WsMetrics|WsConnect|Metrics|Gapless|MediaItemController|PlaybackInfoTracksParity'` → 178 tests OK (2 pre-existing skips), incl. the new never-upgraded + normal-path tests. - `./vendor/bin/phpcs --standard=PSR12` on all 4 changed files → 0 violations. - `php -l` clean on both changed src files. No `start.php`/DI/ctor change (instance property only) → no dual-entrypoint mirroring required. --- ## Reviewer (per-step) — 2026-07-18 Confirming re-review of fix commit `f40de63b` (cumulative findings 1 & 2). Read the fix diff, the current `src/Server/WebSocket/WebSocketServer.php`, `src/Media/Playback/GaplessPlaybackManager.php`, `src/Stats/Metrics/MetricsRegistry.php` (`touchConnection`/`openConnection`/`!isset` fallback), the `Connection`/`ConnectionPool` id model, and the two test files. Ran `php -l` on both changed src files and the two WS test files (`WsMetricsRemoteIpTest` + `WebSocketServerTest`): 19 tests / 59 assertions OK. Adversarial checks performed and cleared: - Set-leak: `$openedConnectionIds` is added ONLY in `onWebSocketConnect()` right after `openConnection()` (same `if ($this->metrics !== null)` block, no early-return between), and removed on EVERY exit — `onClose()` `unset()`s regardless of the gate (:593), and both reject paths `unset()` after `connections->remove()` (:480 rate-limit, :498 auth). Every accepted TCP socket fires exactly one `onClose` (or is rejected, which unsets); rejected sockets whose wrapper is already removed hit `findConnection()===null` in `onClose` and skip the block harmlessly. No orphan path; per-worker instance property (not static/global), bounded by live connections. - Wrongly-skipped upgraded connection: id is recorded in the same block immediately after the `openConnection()` call, so no window exists where a row is opened but the id is untracked. - `onClose` correctness: pool `remove()` + SyncPlay vacate + auth broadcast stay UNGATED; only the metrics `touchConnection()` is gated on `isset(openedConnectionIds[$id])`; id is stable (`spl_object_id.uniqid` on the single wrapper created in `onConnect`, retrieved via `getByObjectId`). - Timer: `touchActiveConnections()` `continue`s only on `!isset(openedConnectionIds[getId()])` — skips never-upgraded, touches all upgraded-live; correct variable, no off-by-one. - Concurrency: array check+mutate pairs have no I/O yield point between them; Workerman event-loop callbacks run to completion — no cross-coroutine corruption for the same id. - Tests bite: `testNeverUpgradedConnectionCreatesNoPhantomMetricsRow` drives onConnect→timer→onClose against a real `MetricsRegistry` and asserts `snapshotConnections()` stays empty — removing either guard makes the `!isset` fallback fabricate a row (count 1 ≠ 0), failing the test. `testUpgradedConnectionIsTouchedByTimerThenFinalTouchedOnClose` asserts open→timer records 1234/5678→close leaves the row — biting the wrongly-skipped direction. - Finding 2: `GaplessPlaybackManager::clearCache()` removed with zero dangling refs (no callers, no `@see`, no test) in `src/`/`tests/`; `$preferencesCache` still read/written by `getPreferences()`. Note (not a finding, out of scope for this commit): a rate-limit/auth reject opens a metrics row via `openConnection()` and then only `unset()`s the tracking id, so that row gets no final touch and lingers until the flush service TTL-prunes it. This behavior predates `f40de63b` (it originates in `882a8f06`: `openConnection()` ran before the reject, and the pre-fix `onClose` already skipped its touch because the wrapper was removed on reject) and is self-healing via TTL prune — the fix does not change it.

Doc files changed (absolute paths): - `/home/sites/phlix/phlix-server/CHANGELOG.md` — [Unreleased]: SV-4.16 JWKS PKCS#8 tolerance + `{"keys":[]}` degrade; item5a HWACCEL_DEBUG demote; item5+ WS S2-metrics real-IP + no phantom rows; item5b logger channel/env routing; item5c3 `bootstrapEnabled()` resident-boot wiring; new **Removed** section (§6 Run A + Run B gapless subsystem); plugin catalog pin → v2.1.8. - `/home/sites/phlix/phlix-server/README.md` — added `PHLIX_DEBUG_EVENTS` env row + a JWKS key-format tolerance / empty-keyset-degrade note. - `/home/sites/phlix/phlix-docs/docs/reference/api/hub-jwks.yaml` — native + PKCS#8 Ed25519 key acceptance; 200 empty-keyset graceful degrade. - `/home/sites/phlix/phlix-docs/docs/reference/config-files.md` — logger handler channel/env routing (per-channel gating); `hub-server-key.pem` accepts native + PKCS#8. - `/home/sites/phlix/phlix-docs/docs/reference/env-vars.md` — clarified `PHLIX_DEBUG_EVENTS` now also gates the `events.log` handler attachment. - `/home/sites/phlix/phlix-ui/CHANGELOG.md` — Unreleased: dead `src/api/music.ts` removal (`7cade5a`). - `/home/sites/phlix/performance_plan.md` (loose, NOT committed) — §6 R1 row + per-command note + §8 D2 updated to record the gapless subsystem REMOVED (client-side impl superseded it), replacing the prior "keep + utilize later". `config/logger.php` verified accurate as-shipped (implementer already updated its routing comments) — left unchanged. Plugin-catalog phlix-docs page describes the catalog conceptually without a pinned-ref version, so no version edit was forced there.
