Records already include fallback, accessibility, privacy, and blocker fields, but S0407-specific notes and helper summaries are missing. * Helper state: `apps/web/src/lib/mediaCatalog.ts` only exposes release groups and fallback coverage. It needs deterministic summaries for accessibility, privacy, metadata, blockers, and release-ready coverage. * Config state: `scripts/media-visual-promotion-config.mjs` and `scripts/public-demo-media-config.mjs` already use explicit inventories, safe path prefixes, docs references, byte budgets, cache policy, and quarantine exclusions. A root gate is missing to reconcile those configs with catalog records, draft manifest blockers, docs, and browser evidence. * Draft state: `assets/generated/phase04/draft-generation-manifest.json` is non-runtime, redacted, budget-gated, and blocker-backed. It still needs root gate coverage that proves drafts do not appear as release-ready runtime, cache, docs, or generated-output records. * Docs state: `docs/media-assets.md`, `scripts/README_scripts.md`, and public-demo docs describe existing Session 04-06 gates. `docs/release.md` and `docs/privacy-and-security.md` still reference older Phase 02 closeout wording and cache values, and no stable doc names `media:gates:check`. * Browser coverage state: Playwright currently verifies battlefield render, failed art fallbacks, public-demo speech/music behavior, blocked audio fallback copy, service-worker readiness, and offline shell reload. It lacks explicit reduced-motion assertions, named failed-media helpers, privacy-safe browser error assertions, screenshot evidence hooks for S0407 paths, and layout overlap checks. **Files Changed**: * `.spec_system/specs/phase04-session07-media-accessibility-privacy-and-performance-gates/tasks.md` - marked T002 complete and updated progress. * `.spec_system/specs/phase04-session07-media-accessibility-privacy-and-performance-gates/implementation-notes.md` - recorded audit findings. **BQC Fixes**: * N/A - audit and documentation only. *** ### Task T003 - Create implementation and security compliance artifacts **Started**: 2026-05-29 21:44 **Completed**: 2026-05-29 21:46 **Duration**: 2 minutes **Notes**: * Created session implementation notes with environment, progress, and task log sections. * Created security compliance artifact scoped to accessibility, privacy, metadata, release blockers, public-demo cache policy, and quarantine review. * Seeded initial security findings for no-credential local execution, sensitive-output redaction, and `EXAMPLES/` quarantine. **Files Changed**: * `.spec_system/specs/phase04-session07-media-accessibility-privacy-and-performance-gates/implementation-notes.md` - initialized and updated task log. * `.spec_system/specs/phase04-session07-media-accessibility-privacy-and-performance-gates/security-compliance.md` - initialized compliance artifact. * `.spec_system/specs/phase04-session07-media-accessibility-privacy-and-performance-gates/tasks.md` - marked T003 complete and updated progress. **BQC Fixes**: * N/A - session artifacts only. *** ### Task T004 - Create media release gate config **Started**: 2026-05-29 21:46 **Completed**: 2026-05-29 21:48 **Duration**: 2 minutes **Notes**: * Added an explicit Session 07 release-gate config with approved and non-approved statuses, safe path prefixes, docs requirements, catalog record expectations, visual/public-demo/draft gate command metadata, browser evidence requirements, lazy media budgets, service-worker cache version, and sensitive-output patterns. * Kept the config explicit and repository-relative so the root checker can avoid broad media discovery. **Files Changed**: * `scripts/media-release-gates-config.mjs` - new release-gate config. * `.spec_system/specs/phase04-session07-media-accessibility-privacy-and-performance-gates/tasks.md` - marked T004 complete and updated progress. * `.spec_system/specs/phase04-session07-media-accessibility-privacy-and-performance-gates/implementation-notes.md` - recorded T004. **BQC Fixes**: * Trust boundary enforcement: config declares allowed path prefixes and sensitive-output patterns for later validation. *** ### Task T005 - Define release-gate fixtures **Started**: 2026-05-29 21:48 **Completed**: 2026-05-29 21:49 **Duration**: 1 minute **Notes**: * Added fixture records for approved, conditional, planned, prototype-only, rejected, unknown, deferred, missing-docs, unsafe-path, and sensitive-output cases. * Added a fixture coverage test so future helper tests can reuse the same cases. **Files Changed**: * `tests/mediaReleaseGates.test.ts` - new release-gate fixture coverage. * `.spec_system/specs/phase04-session07-media-accessibility-privacy-and-performance-gates/tasks.md` - marked T005 complete and updated progress. * `.spec_system/specs/phase04-session07-media-accessibility-privacy-and-performance-gates/implementation-notes.md` - recorded T005. **BQC Fixes**: * Contract alignment: fixtures include the same catalog fields used by the protocol media catalog contract. *** ### Task T006 - Create media release gate checker helpers **Started**: 2026-05-29 21:49 **Completed**: 2026-05-29 21:53 **Duration**: 4 minutes **Notes**: * Added the release-gate checker with exported helpers for config schema checks, redacted issue creation, catalog loading through a bounded `tsx` subprocess, approved/blocker policy validation, docs references, draft manifest checks, browser evidence tokens, safe path validation, and sensitive-output scanning. * Added explicit error codes and deterministic issue ordering. * Added timeout/retry plumbing for dependent media gate scripts. * Smoke-ran `node scripts/check-media-release-gates.mjs --json --skip-dependent-gates`; it executed and failed only on expected future tasks: docs tokens, approved docs evidence, and browser evidence helpers/tests not yet added. **Files Changed**: * `scripts/check-media-release-gates.mjs` - new root checker helpers and CLI surface. * `scripts/media-release-gates-config.mjs` - tightened the `EXAMPLES/` sensitive-pattern check to avoid false positives from normal quarantine path references. * `.spec_system/specs/phase04-session07-media-accessibility-privacy-and-performance-gates/tasks.md` - marked T006 complete and updated progress. * `.spec_system/specs/phase04-session07-media-accessibility-privacy-and-performance-gates/implementation-notes.md` - recorded T006. **BQC Fixes**: * Trust boundary enforcement: all catalog data is loaded through protocol validation and explicit safe path checks. * Failure path completeness: missing files, invalid JSON, invalid config, subprocess failures, and timeouts produce stable issue codes. * External dependency resilience: dependent gate commands run with timeout, bounded output, retry/backoff, and visible failure details. * Error information boundaries: issue details are redacted for secret-like strings and absolute paths before output. *** ### Task T007 - Add catalog helper summaries **Started**: 2026-05-29 21:53 **Completed**: 2026-05-29 21:54 **Duration**: 1 minute **Notes**: * Added summary helpers for accessibility, privacy, metadata, fallback, release blockers, and release readiness. * Added validated summary filters for status, category, group, surface, release state, and bounded limits. * Reused existing deterministic matrix/id ordering. **Files Changed**: * `apps/web/src/lib/mediaCatalog.ts` - added summary interfaces, filters, and helpers. * `.spec_system/specs/phase04-session07-media-accessibility-privacy-and-performance-gates/tasks.md` - marked T007 complete and updated progress. * `.spec_system/specs/phase04-session07-media-accessibility-privacy-and-performance-gates/implementation-notes.md` - recorded T007. **BQC Fixes**: * Contract alignment: summary filters validate protocol enum values before producing results. * State freshness on re-entry: summaries recompute from passed records and never cache catalog state. *** ### Task T008 - Add root media gate command **Started**: 2026-05-29 21:54 **Completed**: 2026-05-29 21:55 **Duration**: 1 minute **Notes**: * Added the root `media:gates:check` npm command beside existing media gate names. **Files Changed**: * `package.json` - added `media:gates:check`. * `.spec_system/specs/phase04-session07-media-accessibility-privacy-and-performance-gates/tasks.md` - marked T008 complete and updated progress. * `.spec_system/specs/phase04-session07-media-accessibility-privacy-and-performance-gates/implementation-notes.md` - recorded T008. **BQC Fixes**: * N/A - package script wiring only. *** ### Task T009 - Implement media release gate CLI orchestration **Started**: 2026-05-29 21:53 **Completed**: 2026-05-29 21:55 **Duration**: 2 minutes **Notes**: * Implemented CLI argument parsing, JSON/text output, nonzero failure exits, deterministic issue ordering, stable issue codes, redacted details, empty catalog detection, missing/invalid file states, and unsupported-tool timeout mapping. * Full command smoke run: `npm run media:gates:check -- --json` executed and returned expected current failures for docs/browser evidence only. **Files Changed**: * `scripts/check-media-release-gates.mjs` - CLI orchestration and reporting. * `.spec_system/specs/phase04-session07-media-accessibility-privacy-and-performance-gates/tasks.md` - marked T009 complete and updated progress. * `.spec_system/specs/phase04-session07-media-accessibility-privacy-and-performance-gates/implementation-notes.md` - recorded T009. **BQC Fixes**: * Failure path completeness: every CLI failure path emits structured issues and exits nonzero. * Error information boundaries: issue details are redacted before text or JSON output. *** ### Task T010 - Validate approved catalog records **Started**: 2026-05-29 21:53 **Completed**: 2026-05-29 21:55 **Duration**: 2 minutes **Notes**: * Added approved-record checks for status, protocol release readiness, release blockers, fallback, accessibility, privacy, required surfaces, required outputs, mirrors, safe paths, metadata, browser support, total byte budgets, and docs evidence. * Current gate output reports only docs evidence failures for approved records; media contract, accessibility, privacy, metadata, fallback, browser support, and budget checks pass for the two approved battlefield records. **Files Changed**: * `scripts/check-media-release-gates.mjs` - approved catalog validation. * `.spec_system/specs/phase04-session07-media-accessibility-privacy-and-performance-gates/tasks.md` - marked T010 complete and updated progress. * `.spec_system/specs/phase04-session07-media-accessibility-privacy-and-performance-gates/implementation-notes.md` - recorded T010. **BQC Fixes**: * Contract alignment: approved record checks compare catalog fields against the explicit release-gate config and protocol release-readiness result. *** ### Task T011 - Validate non-approved catalog and draft blockers **Started**: 2026-05-29 21:53 **Completed**: 2026-05-29 21:55 **Duration**: 2 minutes **Notes**: * Added non-approved catalog status and blocker validation. * Added catalog draft validation that prevents runtime outputs and requires blockers. * Added draft manifest validation for non-runtime policy, staging-only output, provider secret/raw payload flags, allowed statuses, and release blockers. * Current gate output shows blocked catalog and draft policy checks pass for 12 blocked catalog records and 11 draft manifest records. **Files Changed**: * `scripts/check-media-release-gates.mjs` - blocked catalog and draft validation. * `.spec_system/specs/phase04-session07-media-accessibility-privacy-and-performance-gates/tasks.md` - marked T011 complete and updated progress. * `.spec_system/specs/phase04-session07-media-accessibility-privacy-and-performance-gates/implementation-notes.md` - recorded T011. **BQC Fixes**: * Trust boundary enforcement: draft manifest records are checked for non-runtime staging boundaries and sensitive provider flags. *** ### Task T012 - Validate visual and public-demo configs **Started**: 2026-05-29 21:53 **Completed**: 2026-05-29 21:55 **Duration**: 2 minutes **Notes**: * Added dependent validation for `scripts/check-visual-media-promotion.mjs`, `scripts/check-public-demo-media.mjs`, and `scripts/check-media-generation-manifest.mjs` through bounded JSON subprocesses with retry/backoff. * Added public-demo service-worker cache version and lazy media precache validation. * Full `npm run media:gates:check -- --json` run checked both dependent gates successfully; remaining failures are docs and browser evidence tokens that belong to later tasks. **Files Changed**: * `scripts/check-media-release-gates.mjs` - dependent gate and public-demo cache/lazy policy validation. * `.spec_system/specs/phase04-session07-media-accessibility-privacy-and-performance-gates/tasks.md` - marked T012 complete and updated progress. * `.spec_system/specs/phase04-session07-media-accessibility-privacy-and-performance-gates/implementation-notes.md` - recorded T012. **BQC Fixes**: * External dependency resilience: dependent checks use timeout, retry/backoff, max output, and explicit failure-path reporting. * Failure path completeness: invalid JSON, nonzero exits, stale cache versions, and lazy-media precache violations produce stable issue codes. *** ### Task T013 - Tighten app media catalog notes **Started**: 2026-05-29 21:55 **Completed**: 2026-05-29 21:57 **Duration**: 2 minutes **Notes**: * Added S0407 notes to approved battlefield runtime records for fallback, accessibility, privacy, release-gate, docs, and browser evidence coverage. * Added S0407 blocker notes to conditional reference, portrait, brand, public-demo icon, showcase, speech, and music records without changing their non-approved statuses. * Updated shared privacy helper notes for catalog records and draft records. **Files Changed**: * `apps/web/src/data/mediaCatalog.ts` - S0407 catalog notes. * `.spec_system/specs/phase04-session07-media-accessibility-privacy-and-performance-gates/tasks.md` - marked T013 complete and updated progress. * `.spec_system/specs/phase04-session07-media-accessibility-privacy-and-performance-gates/implementation-notes.md` - recorded T013. **BQC Fixes**: * Contract alignment: no conditional status was promoted;
