Mark 05d00509bf docs(01-04): complete offscreen port keepalive + OFFSCREEN_READY handshake plan

- Add 01-04-SUMMARY.md with TDD RED/GREEN/REFACTOR gate records,
  acceptance grep gates, threat mitigations (T-1-04, T-1-NEW-04-01),
  Plan 05 SW-side handoff (REQUIRED sender.id === chrome.runtime.id
  check), and 1 Rule 1 deviation documented
- Advance STATE.md Plan counter 4 → 5, progress 43% → 57%
- Append 3 decisions to STATE.md Accumulated Context
- Update ROADMAP.md: 01-04-PLAN checkbox → [x], phase progress row 3/7 → 4/7

REQ-video-ring-buffer NOT marked complete — still pending Plan 07
ffprobe D-12 gate per the requirement's traceability.

Core value: When an operator hits a bug, one click MUST produce a self-contained archive that lets support reproduce what happened — in under 5 s, no server, no password leaks. Current focus: Phase 1 — Stabilize Video Pipeline

Decisions

Decisions are logged in PROJECT.md Key Decisions table (DEC-001 through DEC-012, all SPEC-Accepted and locked for Phase 1). Recent decisions affecting current work:

Phase 1 framing: roadmap treats the existing codebase as a partially-broken first attempt to be remediated against the SPEC, not as greenfield. The 7 P0 defects from the audit are split across phases 1–3 along commit boundaries; phase 4 is end-to-end SPEC §10 smoke verification.
All 12 SPEC decisions (DEC-001..DEC-012) are LOCKED for Phase 1. Changing any of them requires a formal ADR; none are formally LOCKED in the ingest classification, so a future ADR can revise.
[Phase ?]: Doc cascade: amendments append (do not replace) original DEC/CON blocks to preserve SPEC provenance — Established convention for future SPEC-amending phases; downstream readers see both old + new with citation
[Phase ?]: Manifest: drop alarms permission entirely rather than retain for re-use — Plan 05 deletes the alarms code path; declaring unused permissions expands attack surface (T-1-02)
[Phase ?]: Pinned vitest at ^4 (4.1.6 latest stable; 5.x still beta on 2026-05-15)
[Phase ?]: Phase 1 Wave-0 test infra: 4 RED tests committed against not-yet-existent src/offscreen/recorder.ts — pins contracts for Plans 03+04
[Phase ?]: Reverted premature REQ-video-ring-buffer Complete marking left by Plan 01-01; satisfied by Plans 03+04+07, not by Wave-0 RED tests
[Phase 01-03]: Bundled OffscreenLogger into Task 2 commit (Rule 3 blocking dependency — recorder.ts cannot typecheck without the import)
[Phase 01-03]: Defensive bootstrap guard (typeof chrome check) lets pure ring-buffer test import recorder module without chrome stub
[Phase 01-03]: Removed SW-side VIDEO_CHUNK/VIDEO_CHUNK_SAVED branches + IndexedDB helpers inline (tsc-clean requires; Plan 05 owns remaining SW shrink)
[Phase 01-04]: Kept Plan 03's defensive bootstrap guard (typeof chrome / per-API existence checks) instead of Plan 04's verbatim unguarded block — Plan 04's verbatim block regressed ring-buffer and codec-check tests (they don't stub full chrome surface); restored guard preserves Plan 02 RED contract while satisfying Plan 04's new GREEN contract. Rule 1 deviation.
[Phase 01-04]: T-1-04 SW-side sender check documented redundantly (4 places in recorder.ts) for Plan 05 executor visibility — Offscreen is trusting party; SW is validating party. Documenting in module header, port-name constant, threat-mitigation comment near bootstrap, and inline at connectPort makes the contract impossible to miss when grepping for T-1-04 during Plan 05.
[Phase 01-04]: REFACTOR pass NOT skipped: stale 'Plan 04 wires this' comments replaced with actual D-17/Pattern 5 citations — Forward-pointing TODO-style comments became misleading after the work landed; minimal correctness-preserving comment update with all 9 tests still GREEN.

Pending Todos

None yet.

Blockers/Concerns

(informational) chrome.tabCapture requires a user gesture on first activation — Phase 3 (P0-4) restores this by moving the call into the popup click handler; until Phase 3 lands, recording cannot start cleanly even if Phase 1's pipeline is correct. Phases 1–3 should not be re-ordered.
