# Bazarr Homarr slice: source checks, not live acceptance

Issue: [#272](https://github.com/ajnart/selfhost-skills/issues/272).
Reference base: `573a206e`, [#309](https://github.com/ajnart/selfhost-skills/pull/309).
The shared [Homarr Link contract](homarr-integration-contract.md) applies.

## Stage 1: historical descriptor-only source phase

The record below describes corrected source
`b28da7a09d19dbab3b47d61d562c20f7990e3fb9` against the original reference base.
Its pending registration/reference statements and test gate are historical;
the frozen-reference normalization record follows the official sources.

## Credentials and own Setup

The Catalog pins `lscr.io/linuxserver/bazarr:version-v1.6.0`. Bazarr v1.6.0
generates one unscoped API key, not separate read-only integration keys.
Setup preserves Basic authentication and discovers `auth.apikey` through the
existing App-local `h.ConfigValue` helper. It registers the discovered value
for redaction before any API request and stores it as `BAZARR_API_KEY` through
`h.SetSecret` only after verifying `/api/system/status` and `/api/badges`.
API authentication uses the `X-API-KEY` header, never a query argument.

Every credential step Check and App Check probes both endpoints afresh.
A valid saved key is reused without rereading configuration or rewriting any
setting. A missing key or a key rejected with 401/403 is rediscovered from the
same App-local helper. Other failures do not replace a saved credential.
Recovery: run `self-host setup bazarr`, then `self-host setup homarr`.
If recovery fails, inspect Bazarr's Status and Settings > General > Security;
do not disable authentication or paste a key into agent messages.

The existing Admin login and media mount are unchanged. This slice does not
configure Sonarr/Radarr, language profiles, path mappings or subtitle providers.
Provider account choices remain manual; no external account is created and no
subtitle is downloaded. The checked reference base has no Bazarr-owned Links;
none is removed or replaced here.

## Descriptor and native data

`internal/apps/homarr/target_bazarr.go` defines `bazarrTarget() target`.
Only the #262 registry owner should add `bazarrTarget()` to `targets.go`.
Until registration, the compiled Homarr App does not schedule this new Link.
This lane changes neither the registry nor shared reconciliation.

Homarr v2.4.1 source `ebbd4876d25a51151444a009ab596e1154d62880` defines:

- Integration kind `bazarr`, credential alternative `apiKey`, internal Address
  `http://bazarr:6767`; the browser Address remains independent.
- Native widget `bazarr`, showing missing episode and movie subtitles, provider
  issues and health issues with all four documented visibility options enabled.
- Shared Stats keys `episodes`, `movies`, `providers`. These are missing
  subtitle counts and throttled-provider issues, not library size or configured
  provider counts. Ownership and stable entry IDs come from the reference seam.
- Native query `widget.bazarr.getBadges` with Homarr's returned `integrationId`.
  Link verification validates all five nonnegative integer badge counts and both
  SignalR string fields after validating the peer's live API credential.

Zero counts and `DOWN` SignalR status are legitimate when media peers are absent
or the inventory is empty; neither is an authentication failure. Missing/null
fields, rejected credentials, malformed data and unsuccessful native queries
are failures, not an empty library or tile-only success.

## Verification and remaining gate

Remaining focused coverage is exactly the two baseline Bazarr App tests:
`TestSetupThenCheckThenRerunSkips` and
`TestFailingStepHintNamesTheSetupCommand`. The first checks successful Setup and
Check, saved API credentials, valid zero-count responses and rerun preservation
without authentication updates, with configuration still present. Missing-config
or configuration-reread avoidance is not test coverage. Its maintained fixture
serves `/`, `/api/system/settings`, `/api/system/status` and `/api/badges`. The
second covers a failed settings update and its Settings hint. Credential-change,
malformed-data rejection and Homarr descriptor/count-guard behavior remain
source/schema/compile-only pending native proof, not final-HEAD test coverage.

The entirely agent-added 135-line `target_bazarr_test.go` and the added functions
`TestAPIReadinessRejectsMissingFieldsAndAuthenticationErrors` (all seven table
cases) and `TestSetupRecoversExternallyChangedKeyAndCheckProbesAfresh` were removed
with explicit parent authorization, along with their exclusive fixture controls.
The earlier parent-authored delegation request was not an actual human explicit
unit-test request. No baseline function or implementation was removed and no
replacement tests were added. Added named test/helper function count against
fixed base `573a206e2b4a76574fd7e8cbd1f21c5a4c2fd37d` is zero.

The final post-correction local gate passed on only the remaining test tree:
`GOFLAGS=-buildvcs=false`, empty `gofmt -l .`,
`go build ./...`, `go vet ./...`, `go vet -tags e2e ./e2e/`, `go test ./...`,
race tests for TUI, Activity, Bazarr and Homarr, `bash -n install.sh` and
`git diff --check`. Focused/full/race tests ran with `-count=1`; none of the
removed tests was part of this gate. No e2e-tagged runtime tests were run.

Live proof is blocked by reference acceptance and parent-controlled capacity.
No Docker, browser, installer, person's Project, protected secret file or browser profile
was accessed during this lane. Before readiness, register the descriptor and
explicitly authorize a disposable isolated Project, record resolved Homarr and
Bazarr image digests, and verify real badge/Stats rendering, both install orders,
late installation, restart, changed credentials and owned-only removal/reinstall.
Keep the PR draft and the issue open until those conditions are met.

Context7 discovery was attempted but its quota was exhausted. The selected
contracts were verified directly against official tagged source instead.

## Stage 2: frozen-reference normalization, source only

Normalized source pin: `ee5de2c1939965789649ddf3541441306444d740`.
The subsequent source-check documentation commit changes no production or tests.

Reference #309 is merged and #262 closed. This phase merges frozen main
`6b82c55fb890c11a1388bd4e5a2f10b632ff4f7c` normally into the existing Bazarr
branch at merge `e0bb36bde7a101295bc9280c3fbfcf9379601fff`, preserving corrected
`b28da7a09d19dbab3b47d61d562c20f7990e3fb9`. No merge conflicts occurred.
The frozen tree equals final reference evidence commit
`33e7fbccb7541d2bbf1d81968eb21c35a1b5bfd7`; its tested reference production was
`89301aff17c86b767f5a45076881f2bb7b41db39`. That Immich proof is not Bazarr proof.
The current [peer workflow](https://github.com/ajnart/selfhost-skills/blob/main/docs/agents/homarr-integrations.md)
governs later phases.

The sole registry custodian adds exactly one `bazarrTarget()` call to
`targets.go`, retaining `existingTargets()` and `immichTarget()` unchanged.
The leaf uses the existing `target` contract. Its new preflight delegates to
the already exported, read-only `bazarr.VerifyHomarr(ctx, to)`: each invocation
reads the saved key, registers it for redaction and freshly probes authenticated
`/api/system/status` and `/api/badges` through existing HTTP helpers. Common
`linked` and `add` invoke it before compatibility checks or Homarr credential
creation/update. It does not call credential Setup, read configuration, store
keys, change authentication or require the Admin login/UI. This API-readiness
check does not establish whole Setup, Sonarr/Radarr readiness or provider access.
Missing/rejected keys retain the Bazarr-then-Homarr Setup recovery instructions.

The integration Address stays `http://bazarr:6767`: the actual adapter appends
`/api/system/status` and `/api/badges`, so storing an `/api` suffix would duplicate
it. The browser Address remains separately resolved by the frozen common flow.
Authenticated Homarr API version `2.4.1`, kind `bazarr` and exact `apiKey`
credential compatibility remain centrally enforced. No empty credential or
unauthenticated fallback is introduced.

The unchanged leaf validates authenticated `widget.bazarr.getBadges` data and
its five nonnegative integer counts and two SignalR strings. Central
`verifyData` still runs after the leaf, forces Stats refresh and requires an
advancing positive `updatedAt`, `error: false`, `stale: false` and non-null
`episodes`, `movies`, `providers`. Their missing-subtitle/throttling meanings
remain unchanged. Removal/absence never invokes preflight or native data reads.
Shared reconciliation, ownership, legacy registrations and images are untouched.

Cached Git source comparison confirms these nine Bazarr-scoped files are
identical at research baseline `ebbd4876d25a51151444a009ab596e1154d62880` and
recorded reference OCI revision `3d4150e59f600876b7e308f857b2f21572b75348`:
`packages/definitions/src/integration.ts`,
`packages/definitions/src/widget-integration-map.ts`,
`packages/integrations/src/bazarr/bazarr-integration.ts`,
`packages/integrations/src/bazarr/bazarr-types.ts`,
`packages/api/src/router/widgets/bazarr.ts`,
`packages/request-handler/src/bazarr.ts`,
`packages/widgets/src/bazarr/index.ts`,
`packages/widgets/src/bazarr/component.tsx` and
`packages/integrations/src/stats/existing.ts`.
This is scoped source provenance, not whole-revision equivalence or current
image attestation; no registry metadata or image was fetched in this phase.

Bazarr App source and its test file remain byte-identical to `b28da7a`.
No new test files, functions, subtests, independent scenarios, fault matrices,
comments or dependencies were added. Direct Bazarr coverage remains exactly
the two baseline tests described above; the descriptor, new preflight routing,
credential changes and malformed/native data guards are source/schema/compile
coverage, not newly implemented test or runtime proof.

The normalized production tree passed the local gate in terminal shell
`sh_13035227d001YlEZe0Pr7AsPnf` using cached Go 1.26.0 with
`GOFLAGS=-buildvcs=false`, `GOTOOLCHAIN=local`, `GOPROXY=off` and `GOSUMDB=off`:
empty `gofmt -l .`, focused Bazarr/Homarr tests, `go build ./...`,
`go vet ./...`, `go vet -tags e2e ./e2e/`, `go test ./...`, race tests for
TUI/Activity/Homarr/Bazarr, `bash -n install.sh` and `git diff --check`.
Focused/full/race tests used `-count=1`; no e2e-tagged runtime tests ran.
Only documentation was completed after this gate; production and test bytes
remain those verified by it.

Keep #320 draft and #272 open. Fresh independent Standards/Spec reviews and the
parent's oracle phase gate remain required before counting this normalization.
Native/rendered values, both installation orders, late-peer scheduling, restart,
credential-change recovery and shared removal/reinstall acceptance remain held
for a separately authorized bounded proof. No runtime consent is active and no
Docker, browser, installer, host/provider/account, protected secret/profile or
Gatus candidate/archive work was performed.

## Stage 3: missing-config scenario removal, source only

Starting pin: `9bb75b06cd1983c75f606e58c603d7e58cbd837b`; frozen reference remains
`6b82c55fb890c11a1388bd4e5a2f10b632ff4f7c`. With parent/oracle approval, remove only
the confirmed agent-authored three-line `os.Remove(config.yaml)` block inside
`TestSetupThenCheckThenRerunSkips`. That added scenario had no explicit human
request and was not required API fixture maintenance. Both baseline functions,
API response fixtures, saved-key and settings-write idempotence assertions remain.
All production, preflight, registry and common bytes stay identical to the
starting pin; previously removed tests stay absent. No tests, helpers, functions,
subtests or scenarios are added. Missing-config/no-reread avoidance, credential
changes and descriptor/preflight/native guards remain source/schema/compile-only.

The corrected remaining test tree passed the cached Go 1.26.0 offline gate
under the same four environment settings recorded above: empty `gofmt -l .`,
build, both vet commands, focused/full tests, race tests for TUI/Activity/Homarr/
Bazarr, `bash -n install.sh` and `git diff --check`. Tests used `-count=1`;
the removed fault trigger was absent from every run. No e2e-tagged runtime ran.
Parent-owned fresh fixed-reference Standards and Spec reviews remain pending;
native proof is held.


## Shared Stats SDK normalization, source and focused HTTP evidence

The original branch history is preserved by forward merges of shared SDK
`0bf67c3c64c229af25f19c1b93264f19cc57a910` and additive metadata SDK
`d069339add5924f942ea6536f77d68e64b165df0`. No registry or common verification
implementation is changed by this peer.

The descriptor now uses a pure `statsSample` callback for `episodes`, `movies`, `providers`.
One common catalog/snapshot/forced-refresh sequence supplies the same values
validated by the leaf. Exact catalog units and value types are checked: counts.
Missing/null fields, invalid counts/units and no-op refreshes fail; legitimate
zeros remain valid. Common timestamp validation remains finite, positive and
advancing; this peer adds no invented clock policy.

Native authenticated peer status/badge checks and all five native count/two SignalR guards remain unchanged. Stats count values may differ from independently cached native badges; both are validated without equating volatile samples.

Units and selected provider keys were checked in immutable Homarr OCI source
`3d4150e59f600876b7e308f857b2f21572b75348`, using
`packages/integrations/src/stats/existing.ts` and, for Frigate,
`packages/integrations/src/stats/providers/frigate.ts`. This is source provenance,
not new image attestation.

Focused HTTP scenarios use the shared `statsFixture` through `verifyData`, with
the native verifier explicitly isolated, and assert one forced refresh for the
owned integration. They cover valid empty/populated samples, invalid selected
values/units and refresh no-op rejection. App and Homarr affected-package tests,
affected-package build/vet, changed-file gofmt and `git diff --check` passed.
No Docker, browser, installer or broad suite was run. These fixtures verify the
source interface; they do not claim real native/rendered acceptance.

#320 remains draft and #272 remains open. Provider setup, rendered native/Stats data and both installation orders still require their own approved bounded proof.
