docs(03-03): Plan 03 SUMMARY — A31 password-filter PARTIAL (32/32 GREEN; cs-injection-world + A31.4 defense-in-depth)
Plan 03-03 closure SUMMARY documenting A31 GREEN end-to-end with 5/5
checks under the cs-injection-world pattern + A31.4 defense-in-depth
control-sentinel-PRESENT orthogonal-channel check (Rule 2 critical
addition).
Empirical contract literally satisfied:
- userEvents.length=1
- sentinel-containing count=0 (proves src/content/index.ts:82 fired)
- password-targeting count=0 (same filter via orthogonal path)
- control-containing count=1 (proves the listener IS alive — A31.2/A31.3
absences are NOT vacuously satisfied)
vitest 171/171 GREEN preserved; Tier-1 FORBIDDEN_HOOK_STRINGS unchanged
at 12 entries; src/content/index.ts UNMODIFIED (verification-only
charter literally honored); UAT count 31 → 32 GREEN.
Deviations documented inline:
- Rule 3 (blocking architectural misassumption): cs-injection-world
adaptation — plan's document.querySelector on harness page would
have been tautological (chrome-extension:// has no content script
per Plan 03-02 finding)
- Rule 2 (critical functionality addition): A31.4 defense-in-depth
control-sentinel-PRESENT check (T-03-03-04 strict mitigation)
Pre-existing A29 zip-mtime race-condition flake disclosed (per
Plan 03-02 SUMMARY) — 3 base runs showed 2/3 PASS, 1/3 FAIL with
no Plan 03-03 changes applied; deferred to Plan 03-05 + Phase 4
hardening per CLAUDE.md SCOPE BOUNDARY rule.
