Closes the second debug session in Phase 1's life (after d12). Both
sessions resolved fast — ~30 min for d12, ~15 min for the RED-test
landing in this one — because the planner had explicitly pre-staged
contingencies (D-12 ffprobe gate + D-13 restart-segments skeleton)
for the assumptions RESEARCH.md flagged HIGH-risk. Neither was a
planning oversight; both were the documented HIGH-risk assumption
activating as expected.
Changes:
- Moved .planning/debug/webm-playback-freeze.md →
.planning/debug/resolved/webm-playback-freeze.md (status:
root-cause-confirmed → resolved).
- Added the Resolution section: root-cause one-liner, applied-fix
description, the 5 files-changed list, the 6 fix-a3 commit hashes,
the in-tree verification matrix, and the explicit operator
next-step (re-run ./smoke.sh, verify Chrome playback +
ffmpeg-clean stderr + the 2 webm-playback.test.ts assertions
flipping GREEN, then Phase 1 closes).
- Updated STATE.md frontmatter `stopped_at`, the Decisions log
with a [Phase 01-07-debug-a3] entry summarising D-13 activation
+ the type renames + the retired old-API surface, and the
Session Continuity block (timestamp, stopped_at narrative,
resume-file pointer).
Phase 1 close is still pending operator regen of
tests/fixtures/last_30sec.webm. REQ-video-ring-buffer must not
be marked complete by this commit — Plan 07's §10 #7 acceptance
criterion owns that and only the in-Chrome playback + ffmpeg-clean
stderr (against a freshly regenerated fixture) can close it.
- Mark .planning/debug/d12-blob-port-transfer-fails.md as
status: resolved; fill in the Resolution section with the
applied fix (5 commit hashes, files changed), verification
output (15/15 tests, tsc clean, vite build green, zero
as-any/ts-ignore in fix-touched files), and inline answers
to the specialist-review questions raised by the planner.
Move the file to .planning/debug/resolved/.
- Update STATE.md frontmatter (stopped_at) + Decisions log
+ Session Continuity to record the D-12 fix landing and
the open Plan 07 ffprobe gate (still requires operator
smoke.sh + ffprobe re-run before Phase 1 can close).
- Land smoke.sh — the operator's D-12 acceptance-gate harness
that surfaced the original failure. Self-contained: dedicated
/tmp/mokosh-smoke-profile, auto-accept desktop-capture picker,
Downloads polling, ffprobe gate, fixture staging.
REQ-video-ring-buffer remains NOT-complete — Plan 07 owns it,
operator must re-run ./smoke.sh to verify the fix end-to-end
in Chrome.
Refs: debug session d12-blob-port-transfer-fails (resolved).
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
Rewrite the Phase 1 one-liner in the Phases list to call out the
chrome.tabCapture -> getDisplayMedia swap, and rewrite Success
Criterion #2 to describe the new operator-selected screen/window
capture and the absence of tab-reattach logic. Phases 2-5 sections are
untouched. The verbatim phrase 'no tab re-attach logic' is preserved
as written in the plan to document the amendment in-place; the
original 'recorder re-attaches to the new active tab' wording is gone.
Replace the REQ-video-ring-buffer bullet to bind the new
getDisplayMedia + offscreen-document acquisition path and drop the
'active-tab' wording (the new API is screen/window-scoped, not
tab-scoped, so there is nothing to re-attach on tab switch). Encoding,
buffer window, and SPEC §10 acceptance citations are unchanged. Adds
CON-display-capture-binding alongside the existing constraint bindings.
Rewrite DEC-003 and DEC-010 rows in the Key Decisions table to reflect
the Phase 01 amendments (getDisplayMedia + long-lived port keepalive),
each citing the .planning/intel/decisions.md amendment block as the
canonical source. Swap the two Constraints bullets that cited
chrome.alarms keepalive and tabCapture binding for replacement
bullets bound to CON-display-capture-binding.
Append RETIRED blocks to CON-tab-capture-binding and
CON-service-worker-keepalive (the two SPEC-derived constraints that are
no longer valid under getDisplayMedia + port-keepalive). Add new
CON-display-capture-binding consolidating the replacement contract.
Originals stay intact for provenance; RETIRED is appended below each.
Append Amendment blocks to DEC-003 (getDisplayMedia replaces tabCapture)
and DEC-010 (long-lived port replaces alarms keepalive) so downstream
phases see the new API contract. Original text intact; amendments are
appended, not replacements. Maintains intel/* provenance for the
Phase 01 doc cascade.
After gsd-plan-phase 1: 7 plans across 7 waves. All gates pass:
- Plan-checker (sonnet) VERIFICATION PASSED on iteration 1
- Decision coverage gate (gsd-sdk): 19/19 decisions covered
- Requirements coverage: REQ-video-ring-buffer in all plans
- Security threat model: T-1-01/02/04 mitigated; T-1-03 accepted residual
Known non-blocking gaps:
- gsd-sdk roadmap.annotate-dependencies failed (t.trim is not a function);
ROADMAP plan-list annotations skipped. Phase 1 plan-list in ROADMAP.md
remains accurate; this is a cosmetic nice-to-have for cross-cutting
constraint visibility.
- 1 plan-checker warning (stale wave prose in Plan 03/04 objectives) was
fixed during decision-coverage revision.

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

Settings chosen for the Mokosh stabilization work:
- model_profile: quality (Opus everywhere except verification)
- git.branching_strategy: phase (gsd/phase-{N}-{slug} per phase)
- workflow.code_review: true with depth=deep (cross-file analysis with
import graphs — appropriate given the SW ↔ offscreen ↔ content-script
messaging interplay)
- workflow.tdd_mode: true (RED/GREEN/REFACTOR gates for eligible tasks,
retrofits regression coverage as we touch each file)
All other settings inherit gsd-sdk defaults (research/plan-check/verifier
on, balanced commit_docs, no Intel/Graphify indexing yet).
