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.
