docs(01): VERIFICATION + Phase 1 closure markers — goal-backward audit GREEN

gsd-verifier goal-backward audit (2026-05-20) returned GREEN verdict on
Phase 1 (Stabilize Video Pipeline + whole-desktop capture + as-automatic-
as-platform-allows recording start):

- 17/17 must-haves verified: 11 REQs/charters + 6 cross-cutting gates
- 14/14 plans complete (01-01..01-09 + 01-11 spike-pivot + 01-12 + 01-13
  + 01-14 + 01-10)
- 5 operator empirical acks: Plan 01-07 (Chrome playback 2026-05-15) +
  Plan 01-13 (harness 2026-05-19) + Plan 01-12 (brand-fit 2026-05-20) +
  Plan 01-10 cycle-2 ("All good" 2026-05-20) + Plan 01-10 brand-rename
  follow-up (2026-05-20)
- Test gates: vitest 153/153 GREEN; UAT harness 24/24 GREEN; Tier-1 grep
  gate 12 FORBIDDEN_HOOK_STRINGS; pre-checkpoint bundle gates PASS
- 7 P0 audit defects: 6 closed in-Phase-1-scope; P0 #6 (data-sensitive
  masking) properly deferred to Phase 2

Marker flips landed:

- STATE.md status reflects Phase 1 COMPLETE; completed_phases 0 → 1
- ROADMAP.md Phase 1 row [ ] → [x] with closure-arc summary
- REQUIREMENTS.md REQ-video-ring-buffer In-progress → Complete 2026-05-20
- VERIFICATION.md committed (orchestrator-bundle pattern per verifier
  protocol)

Forward-looking deferred (NOT gaps):
- Phase 2: REQ-rrweb-dom-buffer + REQ-user-event-log +
  REQ-password-confidentiality (audit P0 #6)
- Phase 5 hardening: getDisplayMedia cursor visibility; setimmediate
  polyfill new Function pre-existing; tabs permission gap; dark-surface
  logo contrast; 2 ffprobe/ffmpeg test flakes

Phase 2 (Stabilize DOM + event-capture privacy) kickoff pending.
