Operator UAT closure for Plan 01-13 Task 9. Patches saveArchive() in
src/background/index.ts with a `finally` block that dispatches
STOP_RECORDING to offscreen (mirrors the existing START_RECORDING
control-plane channel via chrome.runtime.sendMessage), flips
isRecording=false, and calls setIdleMode() — applied to BOTH the
success and empty-buffer-error paths.
Operator UX contract: SAVE click ALWAYS stops the session, regardless of
internal success/empty-buffer outcome. The badge clears, the popup
empties (re-enabling chrome.action.onClicked for restart), and Chrome's
sharing banner closes via the offscreen recorder's stopRecording()
(which nulls mediaStream + stops all tracks + clears the rotation
timer — line 527 of src/offscreen/recorder.ts, already wired since
Plan 01-05).
Trade-off documented inline: empty-buffer path still surfaces a
recovery notification (the catch branch emits RECORDING_ERROR{
error:'empty-video-buffer'} → SW's own onMessage handler runs
setErrorMode + creates a mokosh-recovery-* notif). The finally block
then setIdleMode()'s, so the FINAL visible state is OFF/empty-popup —
clean restart path. The notification stays visible briefly so the
operator sees that something went wrong, then clicks it to start a
new session.
Test count: 94 GREEN (baseline) → 98 GREEN (+4 from
tests/background/save-archive-stops-recording.test.ts).
Files modified:
- src/background/index.ts (saveArchive + finally block; no
PortMessage/Message type changes — STOP_RECORDING already in
MessageType per src/shared/types.ts:14, offscreen handler at
recorder.ts:848 already wired)
Toolchain:
- npx tsc --noEmit: exit 0 (no type errors)
- npm run build: exit 0 (dist/ clean rebuild)
