Two doc updates closing the debug session per the resolved pattern this
phase has established (cf. resolved/d12-blob-port-transfer-fails.md and
resolved/webm-playback-freeze.md):
1. **Move debug session to resolved/** with the Resolution section
filled in (root_cause, fix, verification, files_changed). Status
flipped tdd_red_confirmed -> resolved. Original investigation
notes + bisect results + Option C strategy spec all preserved
in-place — the file is the full provenance trail.
2. **Amend 01-CONTEXT.md D-17** with the new port lifecycle commitments.
Append-only (D-17 itself untouched) per the doc cascade rule
established earlier this phase ("amendments append, do not replace,
to preserve SPEC provenance"). The amendment narrates:
- What was Claude's-discretion at Phase 1 plan time has been
specified by Option C.
- The 290 s pre-emptive setTimeout reconnect (Pitfall 4) is RETIRED.
- The architectural commitments added: PING/PONG health probe,
request-id'd REQUEST_BUFFER/BUFFER, SW retry on port replacement,
outer 10 s hard-timeout, operator-visible EmptyVideoBufferError
surface.
- The 4 pinning contracts added (port-health-probe,
request-id-protocol, port-lifecycle-continuous, plus the
refactored port-reconnect-race).
Suite remains 11 files / 53 tests, all GREEN. Quality gates intact.

Plan 05 closes: src/background/index.ts is now a pure coordinator with
zero video-buffer state, T-1-04 mitigations on both onConnect and
onMessage, OFFSCREEN_READY handshake, port-based buffer fetch via
'video-keepalive' port, IDB orphan cleanup on install, and chrome.offscreen.hasDocument()
re-sync on SW respawn (audit P1 #8). 9/9 vitest tests still green;
tsc clean; no as any / @ts-ignore.
REQ-video-ring-buffer stays pending — Plan 07's ffprobe gate owns the
final completion marker.
- Add 01-03-SUMMARY.md documenting RED -> GREEN gate (Plan 02 tests now
pass), 3 Rule-3 auto-fixes (OffscreenLogger inline, defensive
bootstrap, SW dead-code removal), and Plan 04 / 05 handoff notes.
- Update STATE.md: advance plan counter to 4 of 7 (43%), append
metrics + 3 execution decisions, record session.
- Update ROADMAP.md: mark Plan 01-03 [x] complete.
REQ-video-ring-buffer remains NOT complete — still pending Plans 04
(port keepalive) and 07 (ffprobe acceptance gate).

Plan 01-01 (Wave-0 doc cascade) complete. Six tasks landed atomically
in commits 125c032, fb88830, b1ed2cb, 597d967, 32bc996, 4a5194e. Every
code-touching plan in Phase 1 (01-02..01-07) now reads a consistent
baseline: getDisplayMedia replaces tabCapture in DEC-003; long-lived
port replaces alarms in DEC-010; manifest.json carries the final
Phase-1 permissions set (desktopCapture, activeTab, downloads,
scripting, storage, offscreen).
SUMMARY: .planning/phases/01-stabilize-video-pipeline/01-01-SUMMARY.md
Renames "## Open Questions" header to "## Open Questions (RESOLVED)" and
adds inline RESOLVED markers to each of the three questions:
- Q1 (MediaRecorder timeslice cluster alignment) → D-12 ffprobe gate
(Plan 03 Task 2 + Plan 07 Task 1) + D-13 fallback (pre-staged skeleton
in src/offscreen/recorder.ts per Plan 03)
- Q2 (5-minute port lifetime cap) → Plan 04's 290 s pre-emptive reconnect
plus synchronous onDisconnect → connectPort reconnect path
- Q3 (crxjs path-emit behavior) → Plan 06 Task 2 runtime verification +
conditional src/background/index.ts edit

Two changes:
1. wave: 3 → 6 (cascade: max(wave(05)=4, wave(06)=5)+1 = 6).
2. Task 1 <automated> verify now prefixes the ffprobe invocation with
test -f tests/fixtures/last_30sec.webm && which ffprobe so the gate
fails fast with a clear signal if the human checkpoint never produced
the fixture (instead of ffprobe blowing up with a cryptic file-not-found).

Three changes to resolve the blocker:
1. depends_on: ["03"] → ["03", "05"] — Plan 06 Task 2 conditionally edits
src/background/index.ts which Plan 05 writes; the original wave 2
collocation with Plan 05 was a same-wave file conflict.
2. wave: 2 → 5 (cascade: max(wave(03)=2, wave(05)=4)+1 = 5).
3. files_modified gains src/background/index.ts (Task 2 path-adjustment
edit is now declared in frontmatter so the executor sees the contract).

Plan 05 depends_on: ["03", "04"], so wave must be max(2, 3)+1 = 4, not 2
(cascade from Plan 04 wave change).

Two changes:
1. wave: 1 → 2 (cascade after Plan 02 wave fix)
2. OffscreenLogger: ...args: any[] → ...args: unknown[] for strict-mode
hygiene. Existing Logger / ContentLogger are left on the legacy any[]
pattern (refactoring is out of Phase 1 scope) — divergence documented
via style_divergence_note frontmatter field.

Documents that all 6 tasks are doc-text-only edits with no TypeScript
compilation — cognitive load is substantially lower than code plans of
equal task count. Avoids fragmenting the atomic doc-cascade by splitting
into 01-01a / 01-01b.

Researched Chrome MV3 offscreen + DISPLAY_MEDIA, MediaRecorder cluster
alignment, SW port keepalive, crxjs offscreen entry, ffprobe verification.
Identified the D-12/D-13 fallback hinge: timeslice=2000ms does NOT force
keyframe alignment (Chrome kf_max_dist=100); Pattern 2 (age-trim) may need
to escalate to Pattern 3 (restart-segments) if ffprobe rejects.
Architecture verified against two in-the-wild production extensions
(Proscreen-S3, meeting_mate) using the exact CONTEXT.md D-01..D-05 path.
The OFFSCREEN_READY handshake (audit P1 #12) and long-lived port keepalive
(audit P1 #8) are wired together. .planning/phases/01-stabilize-video-pipeline/01-RESEARCH.md
