Phase 15 Implementation Report
Date: 2026-06-25
1. Executive summary
Phase 15 found and fixed four repository defects: corrupted release-evidence CSV rows, loose JSON media-type matching, nondeterministic visual-test setup, and missing CI integration coverage. Dependency-free validation passes. Final acceptance is blocked because the pinned clean install and all dependency-backed/browser/human/production-like gates could not run.
2. Authoritative inputs reviewed
The Phase 15 prompt, complete Phase 14 repository, Phase 14 handoff, implementation report, decision log, issue register, manifest, route/destination/form/integration/data-flow/consent/analytics/security/privacy/performance/release-gate records, tests, CI, README, and inherited Phase 9 through Phase 13 contracts were reviewed.
3. Test environment
Observed: Debian GNU/Linux 13, Node v22.16.0, npm 10.9.2, Corepack 0.32.0, Python 3.13.5, Chromium 144.0.7559.96. Required: Node 24.17.0 and pnpm 11.9.0. The supplied ZIP contained no .git directory.
4. Clean-room baseline
Fresh extraction and Phase 14 manifest verification passed. Corepack could not fetch pnpm because registry DNS is unavailable; frozen install did not run.
5. Repository integrity
Baseline static audit found 4 High and 7 Medium findings. After remediation, the same audit reports zero findings. Final artifact integrity is governed by the Phase 15 manifest.
6. Static analysis
Sixteen dependency-free validators pass. JavaScript/non-JSX TypeScript syntax and the Python audit script pass. Prettier, ESLint, strict TypeScript, dead-code, dependency/license, and bundle-secret tooling are blocked.
7. Unit testing
Current Vitest suite not run. A media-type regression test was authored and eight dependency-free assertions pass. Historical Phase 14 unit evidence is stale for this release candidate.
8. Integration testing
Current integration suite not run. CI omission was fixed. Historical Phase 14 integration evidence is stale.
9. End-to-end testing
Authored scenarios exist; no current browser execution.
10. Cross-browser testing
Configured projects cover Chromium, Firefox, WebKit, mobile Chrome, and mobile Safari; no current results.
11. Device and viewport testing
Required widths are represented in tests; rendered validation blocked.
12. Zoom and reflow
No current 200/400 percent or OS scaling evidence.
13. Automated accessibility
Axe suites authored; not executed.
14. Keyboard accessibility
Static semantics reviewed; manual keyboard flow not run.
15. Screen-reader testing
NVDA, VoiceOver, and TalkBack not run. No announcement transcript was invented.
16. WCAG 2.2 AA assessment
Criterion-to-evidence matrix produced. Many criteria have static evidence only; conformance is not established.
17. Localization QA
Catalog key parity passes. Native French and Arabic approval remains open.
18. RTL QA
Document direction and logical CSS controls pass; Arabic end-to-end and AT review blocked.
19. Theme QA
Theme foundations pass static checks; no-flash, system changes, contrast, and forced-colors browser evidence blocked. Visual key defect fixed.
20. Visual regression
Canonical Chromium setup fixed. No baselines generated or approved.
21. Design fidelity
Composition/token validators pass; rendered design comparison not performed.
22. Performance
Approved budgets exist; no final build or browser metrics.
23. Bundle analysis
No new runtime dependency added; final chunks and client boundaries not measured.
24. Image and font performance
No production public assets added; final images/fonts/network behavior unmeasured.
25. Security validation
Static request, schema, timeout, idempotency, CSP, redaction, and fail-closed controls pass. Content-type boundary hardened. Dynamic/dependency/vendor/rate-limit evidence blocked.
26. Privacy validation
Static no-PII controls pass. Legal basis, recipients, retention, deletion, transfers, and runtime vendor/log evidence blocked.
27. Consent validation
Optional processing remains disabled; complete consent lifecycle not implemented or tested.
28. Analytics validation
Strict non-PII allowlist passes static review; provider and real consent gating not approved.
29. Destination validation
Registry and routes pass static checks; most production destinations remain blocked or placeholder.
30. Failure simulation
Deterministic scenarios authored; current runtime execution blocked.
31. Idempotency and duplicate handling
Process-local design reviewed; durable cross-instance policy remains blocked.
32. Abuse-control validation
Body size, marker, origin, schema, content type, and honeypot controls present; distributed rate limits absent.
33. Deployment rehearsal
Not run for Phase 15.
34. Rollback rehearsal
Feature-flag strategy documented; not rehearsed.
35. Observability validation
Correlation/redaction foundations exist; monitoring, alerts, retention, and dashboards absent.
36. Content and evidence review
Prohibited-content controls pass; final claims, evidence, assets, copy, and legal approvals remain open.
37. SEO and metadata
Static foundations pass; production-domain and rendered crawl evidence blocked.
38. Browser history and navigation
No PII URL construction found; final browser history matrix not run.
39. Defect summary
Four defects fixed: two High and two Medium. One High Phase 15 acceptance blocker remains open.
40. Retest summary
Targeted static/dependency-free retests pass. Full regression is blocked.
41. Release-gate assessment
Three static gates pass. All executable, browser/human, performance, deployment, and production approval gates remain blocked/open.
42. Accepted exceptions
None.
43. Remaining risks
Cumulative unresolved register: Critical 1, High 21, Medium 17, Low 2.
44. Files added, changed, and removed
Source changes harden content type; tests and CI are corrected; Phase 15 validators, reports, registers, and manifest are added. No authoritative Phase 9 contract was modified. File inventory is in docs/quality/PHASE_15_FILE_CHANGES_v1.0.txt.
45. Exact commands required to reproduce validation
See docs/phase15/COMMAND_MATRIX_v1.0.csv and the Phase 16 handoff. Blocked commands must be run exactly on the pinned toolchain.
46. Final release recommendation
Not ready for Phase 16. See docs/phase15/FINAL_RELEASE_RECOMMENDATION_v1.0.md.
47. Phase 16 readiness assessment
Phase 16 may review blockers and prepare approvals, but must not freeze or deploy a release candidate until P15-005 and all Critical/High release gates are closed or explicitly approved by accountable owners. No exception is currently accepted.
