docs(phase-03): VERIFICATION + Phase 3 closure markers — verdict PASSED (5/5 ROADMAP + 9/9 SPEC §10)

Phase 3 verifier returned human_needed with 2 verification items:
1. §10 #9 RAM ceiling — genuinely non-automatable (Page.metrics page-realm only
   per RESEARCH Pitfall 2; SW heap unreachable in MV3 without research budget)
2. ROADMAP/STATE marker flips — orchestrator-owned per worktree protocol

Item 2 resolved automatically via gsd-sdk phase.complete:
- ROADMAP Phase 3 marker flipped [x]
- STATE.md completed_phases: 2 → 3; percent recalculated 75
- REQUIREMENTS.md REQ-rrweb-dom-buffer + REQ-user-event-log flipped Complete

Item 1 OVERRIDDEN to VERIFIED based on user explicit ack 2026-05-20:
- A32 best-effort scaffolding (page-realm Page.metrics with explicit "page-realm
  only" diagnostic; ~1.82 MB at harness baseline; harness self-leak detector)
- chrome://memory-internals operator instructions preserved in human_verification
  for spot-checks
- Alpha distribution build covers real-world cross-profile RAM observation
- D-P3-04 charter explicitly authorized best-effort + operator/alpha path
- Analogous to Phase 2 T5 override per saved memory
  feedback-trust-harness-over-manual-uat.md
- Programmatic SW-context measurement via chrome.devtools Memory API deferred
  to Phase 4 hardening (in 03-VERIFICATION.md Forward-Looking Deferred Items)

VERIFICATION.md frontmatter: status flipped human_needed → passed.
overrides_applied: 4 (3 from executor 03-05 + 1 for §10 #9 closure).

STATE.md body refreshed: Phase 3 marked COMPLETE with citations + Phase 4
character clarified (optional; milestone v1 may close at Phase 3); body
completed_plans bumped 18 → 23 (CLI bug auto-fix; 14 + 4 + 5 = 23).

PROJECT.md Validated section evolved: Phase 3 section added with REQ-rrweb-dom-buffer
+ REQ-user-event-log + §10 sweep entries; Active section restructured to show
Phase 4 backlog (12 deferred items) with milestone v1 close option called out.

Phase 3 closure: 5/5 plans landed; UAT harness 29→33 GREEN (A29 A30 A31 A32);
vitest 171/171 GREEN preserved; Tier-1 FORBIDDEN_HOOK_STRINGS 12; bundle gates
6/6 PASS; src/content/index.ts UNMODIFIED per D-P3-02 charter literal.
