# AtlasTerm/JoeSSH Codex Session Handoff ## 0. Latest continuation state (2026-06-09 controller) - ACTIVE LANE LEDGER + SAFE DISPATCH Current controller baseline: - Web admin static shell byte-budget guard continued under the active Web admin lane: `apps/web/src/accessibilityContracts.test.ts` now assigns an explicit byte budget to every audited static shell source carrier and verifies the budget inventory matches the pinned source inventory, with a fixture proving oversized static text assets fail the source-review contract, so static HTML, metadata, text, SVG, deployment header, and Service Worker assets cannot silently accumulate hidden payloads or oversized fallback content while preserving the existing exact-content and source hygiene guards. - Verification for this Web admin static shell byte-budget slice is green: `npm run test:web -- accessibilityContracts` (1/1), strict UTF-8 focused static-shell byte-budget probe (`static-shell-byte-budgets=pass`, `static-shell-budgeted-files=10`, `static-shell-largest-budget=4096`, `static-shell-largest-asset=2828`), `npm run qa:web` (Web typecheck, 160/160 Web tests, production build + SRI), `npm run qa:security-headers` (6/6 plus built scan), `npm run lint`, `npm run qa:handoff-hygiene` (114/114 plus live scan), strict UTF-8 probing, stop-warning count, and final `C:\Tools\agenttool` process scan all pass. - Web admin static manifest JSON duplicate-key guard continued under the active Web admin lane: `apps/web/src/accessibilityContracts.test.ts` now lexically scans static JSON shell sources for duplicate object keys before relying on parsed manifest metadata, with fixtures pinning both top-level and nested shortcut duplicate-key regressions, so `apps/web/public/manifest.json` cannot hide alternate launcher, shortcut, icon, scope, or integration metadata behind JSON parser last-write-wins behavior while still satisfying the parsed install-metadata baseline. - Verification for this Web admin static manifest JSON duplicate-key slice is green: `npm run test:web -- accessibilityContracts` (1/1), strict UTF-8 focused JSON probe (`static-json-duplicate-keys=none`, `static-json-files=1`, `static-manifest-parse=ok`), `npm run qa:web` (Web typecheck, 160/160 Web tests, production build + SRI), `npm run qa:security-headers` (6/6 plus built scan), `npm run lint`, `npm run qa:handoff-hygiene` (114/114 plus live scan), strict UTF-8 probing, stop-warning count, and final `C:\Tools\agenttool` process scan all pass. - Web admin static shell text-format hygiene guard continued under the active Web admin lane: `apps/web/src/accessibilityContracts.test.ts` now scans every collected static shell source for carriage returns, CRLF/bare-CR line endings, missing terminal newlines, duplicate terminal newlines, and trailing spaces or tabs, with fixtures pinning each failure shape, so static HTML, metadata, text, SVG, deployment header, and Service Worker carriers keep deterministic LF-only source formatting and cannot hide review-noise or packaging drift in whitespace-only changes. - Verification for this Web admin static shell text-format hygiene slice is green: `npm run test:web -- accessibilityContracts` (1/1), strict UTF-8 focused static-shell format probe (`static-shell-line-endings=lf`, `static-shell-format-files=10`, `static-shell-terminal-newline=single`, `static-shell-trailing-whitespace-lines=0`), `npm run qa:web` (Web typecheck, 160/160 Web tests, production build + SRI), `npm run qa:security-headers` (6/6 plus built scan), `npm run lint`, `npm run qa:handoff-hygiene` (114/114 plus live scan), strict UTF-8 probing, stop-warning count, and final `C:\Tools\agenttool` process scan all pass. - Web admin static shell text-encoding hygiene guard continued under the active Web admin lane: `apps/web/src/accessibilityContracts.test.ts` now scans every collected static shell source for disallowed C0/C1 controls, Unicode format characters, replacement characters, and common mojibake fingerprints while pinning fixtures for NUL, C1, bidirectional format controls, UTF-8 punctuation mojibake, and emoji mojibake, so static HTML, metadata, text, SVG, deployment header, and Service Worker carriers cannot silently ship hidden controls or corrupted visible copy outside the audited source-review inventory. - Verification for this Web admin static shell text-encoding hygiene slice is green: `npm run test:web -- accessibilityContracts` (1/1), strict UTF-8 focused static-shell encoding probe (`static-shell-encoding=clean`, `static-shell-encoding-files=10`, `static-shell-control-chars=0`, `static-shell-format-chars=0`, `static-shell-mojibake-fingerprints=0`), `npm run qa:web` (Web typecheck, 160/160 Web tests, production build + SRI), `npm run qa:security-headers` (6/6 plus built scan), `npm run lint`, `npm run qa:handoff-hygiene` (114/114 plus live scan), strict UTF-8 probing, stop-warning count, and final `C:\Tools\agenttool` process scan all pass. - Web admin static Service Worker cache-policy guard continued under the active Web admin lane: `apps/web/src/accessibilityContracts.test.ts` now requires `apps/web/public/sw.js` to keep the exact audited `install`/`activate`/`fetch` event inventory, cache name, 100-entry trim limit, five-entry precache set, install `skipWaiting`, activate old-cache cleanup plus `clients.claim`, GET and same-origin fetch boundaries, manifest/static/navigation handling, offline navigation fallback, stale-while-revalidate static asset path, and oldest-entry trim behavior, so the offline-support carrier cannot silently add or weaken cache lifecycle, request-scope, or fallback semantics while remaining inside the reviewed static shell source inventory. - Verification for this Web admin static Service Worker cache-policy slice is green: `npm run test:web -- accessibilityContracts` (1/1), strict UTF-8 focused Service Worker probe (`service-worker-events=install,activate,fetch`, `service-worker-cache-name=atlasterm-admin-v1`, `service-worker-static-assets=5`, `service-worker-max-cache-entries=100`, `service-worker-navigation-fallback=offline-503`, `service-worker-trim-policy=oldest-entry`), `npm run qa:web` (Web typecheck, 160/160 Web tests, production build + SRI), `npm run qa:security-headers` (6/6 plus built scan), `npm run lint`, `npm run qa:handoff-hygiene` (114/114 plus live scan), strict UTF-8 probing, stop-warning count, and final `C:\Tools\agenttool` process scan all pass. - Web admin static shell source inventory guard continued under the active Web admin lane: `apps/web/src/accessibilityContracts.test.ts` now requires the collected static shell sources to match the exact audited inventory for the Vite entry document, fallback documents, extensionless deployment headers, favicon, manifest, robots/humans text metadata, `.well-known/security.txt`, and the Service Worker asset, while the non-Service Worker shell subset must match the same inventory without `apps/web/public/sw.js`. The slice self-debugged an initially missing `.well-known/security.txt` path and now pins its exact security-contact metadata baseline too, so hidden public text assets cannot bypass source-review inventory, contact-policy drift, or broader shell capability scans. - Verification for this Web admin static shell source inventory slice is green: `npm run test:web -- accessibilityContracts` (1/1 after self-debugging the missing `.well-known/security.txt` inventory entry), strict UTF-8 focused source-inventory probe (`static-shell-inventory=exact`, `static-shell-source-count=10`, `non-sw-static-shell-source-count=9`, `.well-known/security.txt-baseline=exact`, `.well-known/security.txt-lines=7`), `npm run qa:web` (Web typecheck, 160/160 Web tests, production build + SRI), `npm run qa:security-headers` (6/6 plus built scan), `npm run lint`, `npm run qa:handoff-hygiene` (114/114 plus live scan), strict UTF-8 probing, stop-warning count, and final `C:\Tools\agenttool` process scan all pass. - Web admin static text asset guard continued under the active Web admin lane: `apps/web/src/accessibilityContracts.test.ts` now requires `apps/web/public/robots.txt` and `apps/web/public/humans.txt` to match the exact audited static text asset baselines, including the root crawler directive and the AtlasTerm team/site metadata block, so public text metadata cannot silently drift into different crawl behavior, product attribution, tooling claims, or hidden markup/script carrier content outside the reviewed Web Admin shell source collection. - Verification for this Web admin static text asset slice is green: `npm run test:web -- accessibilityContracts` (1/1), strict UTF-8 focused text asset probe (`robots.txt-baseline=exact`, `robots.txt-lines=2`, `humans.txt-baseline=exact`, `humans.txt-lines=7`), `npm run qa:web` (Web typecheck, 160/160 Web tests, production build + SRI), `npm run qa:security-headers` (6/6 plus built scan), `npm run lint`, `npm run qa:handoff-hygiene` (114/114 plus live scan), strict UTF-8 probing, stop-warning count, and final `C:\Tools\agenttool` process scan all pass. - Web admin static deployment header asset guard continued under the active Web admin lane: `apps/web/src/accessibilityContracts.test.ts` now requires `apps/web/public/_headers` to match the exact audited deployment HTTP header asset baseline, including the root route selector, CSP `frame-ancestors 'none'`, `X-Frame-Options: DENY`, `X-Content-Type-Options: nosniff`, strict-origin referrer policy, and disabled camera/microphone/geolocation/payment/USB/sensor capability directives, so the static deployment header carrier cannot silently drift away from the reviewed clickjacking, MIME, referrer, and browser-capability boundary while remaining covered by the broader shell source-review scan. - Verification for this Web admin static deployment header asset slice is green: `npm run test:web -- accessibilityContracts` (1/1), strict UTF-8 focused deployment-header probe (`deployment-headers-baseline=exact`, `deployment-headers-lines=6`, `deployment-headers-header-lines=5`), `npm run qa:web` (Web typecheck, 160/160 Web tests, production build + SRI), `npm run qa:security-headers` (6/6 plus built scan), `npm run lint`, `npm run qa:handoff-hygiene` (114/114 plus live scan), strict UTF-8 probing, stop-warning count, and final `C:\Tools\agenttool` process scan all pass. - Web admin static favicon asset guard continued under the active Web admin lane: `apps/web/src/accessibilityContracts.test.ts` now reads `apps/web/public/favicon.svg` through the static shell source collection and requires the exact audited JoeSSH Admin 32px rounded dark tile plus blue/white mark SVG baseline, so the browser favicon asset cannot silently drift into a different brand, geometry, or embedded markup surface outside reviewed Web Admin shell assets. - Verification for this Web admin static favicon asset slice is green: `npm run test:web -- accessibilityContracts` (1/1), strict UTF-8 focused favicon SVG probe (`favicon-svg-baseline=exact`, `favicon-svg-lines=5`, `favicon-svg-paths=2`), `npm run qa:web` (Web typecheck, 160/160 Web tests, production build + SRI), `npm run qa:security-headers` (6/6 plus built scan), `npm run lint`, `npm run qa:handoff-hygiene` (114/114 plus live scan), strict UTF-8 probing, stop-warning count, and final `C:\Tools\agenttool` process scan all pass. - Web admin static manifest install-metadata guard continued under the active Web admin lane: `apps/web/src/accessibilityContracts.test.ts` now parses `apps/web/public/manifest.json` and requires the exact audited JoeSSH Admin install metadata baseline, including launcher identity, description, root `id`/`start_url`/`scope`, standalone display, colors, orientation, three dashboard/device/audit shortcuts, productivity/utilities categories, and the single SVG maskable icon, so the static Web Admin manifest cannot silently drift into a different install surface while the advanced app-integration key guard remains in place. - Verification for this Web admin static manifest install-metadata slice is green: `npm run test:web -- accessibilityContracts` (1/1), strict UTF-8 focused manifest-baseline probe (`manifest-baseline=exact`, `manifest-shortcuts=3`, `manifest-icons=1`), `npm run qa:web` (Web typecheck, 160/160 Web tests, production build + SRI), `npm run qa:security-headers` (6/6 plus built scan), `npm run lint`, `npm run qa:handoff-hygiene` (114/114 plus live scan), strict UTF-8 probing, stop-warning count, and final `C:\Tools\agenttool` process scan all pass. - Web admin static shell style-block count guard continued under the active Web admin lane: `apps/web/src/accessibilityContracts.test.ts` now counts `
