Captures the RED contracts that the webm-playback-freeze debug
session landed (before this fix-a3 cycle started) plus the original
Plan 07 smoke fixture they run against. None of these files were
modified by this fix cycle — they are landed as-is from the debug
session to make the test history bisectable.
Files staged:
- tests/offscreen/segment-keyframes.test.ts
Three describe blocks (~340 LOC):
* documentation — pure-simulation tests that pin the D-09..D-11
failure mode as executable evidence (regression guard against
re-introducing single-continuous-recorder semantics)
* GREEN-pinning — pure-simulation tests that pin the D-13
segment-keyframe invariant
* production-driven — imports src/offscreen/recorder.ts and
asserts (i) `getSegments` exported as a function, (ii) it
returns at most 3 Blobs. THIS BLOCK IS NOW GREEN after the
D-13 activation in the prior commits — was the genuine TDD
anchor for fix-a3.
- tests/offscreen/webm-playback.test.ts
Two empirical-ffmpeg assertions on tests/fixtures/last_30sec.webm:
* zero "Error submitting packet to decoder" lines from the
VP9 decoder
* no "File ended prematurely" container-finalization error
Both STAY RED in this commit because the committed fixture is
still the stale one from Plan 07's pre-fix smoke. They flip
GREEN after the operator runs ./smoke.sh to regenerate the
fixture against the D-13 recorder — see the closing message
and the NEXT-STEP block of the resolved debug session.
- tests/fixtures/last_30sec.webm
The 2.1 MB Plan 07 smoke artifact. Committed deliberately so
the empirical RED test has something to run against. Will be
overwritten by the next ./smoke.sh run (single-file rotation —
the path is fixed by the smoke script + zip extraction step
in the debug-session reproduction).
Verification:
- npx vitest run --reporter=dot → Tests 2 failed | 28 passed (30)
- The 2 fails are EXACTLY the two empirical-ffmpeg assertions in
webm-playback.test.ts; the structural production-driven block
in segment-keyframes.test.ts is fully GREEN.
- npx tsc --noEmit clean.
- npm run build succeeds.
Operator action required before Phase 1 close (Plan 07 still owns
REQ-video-ring-buffer): re-run ./smoke.sh per the documented
6-step reproduction in the debug session, then re-run
`npx vitest run tests/offscreen/webm-playback.test.ts` and
expect both assertions to flip GREEN. Plan 07 success criterion
§10 #7 (playback) lands at that point.
