Plan 01-13 Task 9 operator UAT closure. Operator 2026-05-19 empirical
session: SAVE click downloaded zip but recording stayed live (badge=REC,
sharing banner persisted, subsequent toolbar press re-opened SAVE-only
popup). Operator pressed 4×, got 2 zips + confusion.
Root cause: src/background/index.ts saveArchive() returns success after
chrome.downloads.download without signaling offscreen to stop or
transitioning the SW state machine — SPEC `Тз расширение фаза1.md`
"one click MUST produce a self-contained archive" was over-extended to
"always-on" framing by the implementation.
Fix contract (RED today; GREEN after src/background/index.ts patch):
A: setBadgeText({text:''}) called post-save (setIdleMode side effect)
B: setPopup({popup:''}) called post-save (re-enables chrome.action.onClicked
restart path per MV3 contract)
C: chrome.runtime.sendMessage({type:'STOP_RECORDING'}) dispatched
(offscreen recorder.ts:848 STOP_RECORDING case already wired —
no offscreen-side change needed)
D: NO mokosh-recovery-* notification fires (deliberate stop ≠ error;
mirrors Bug B `user-stopped-sharing` suppression branch from
.planning/debug/resolved/01-09-recovery-flow.md)
Tests A/B/C RED (assertion errors `expected 0 >= 1`); Test D GREEN today
as the regression guard against fix over-rotating to setErrorMode.
Test architecture mirrors tests/background/request-id-protocol.test.ts:
synthetic BUFFER response delivered via port.onMessage listeners to drive
saveArchive's request-id'd buffer fetch to completion. Empty-segments
BUFFER causes createArchive → EmptyVideoBufferError → catch branch; the
fix's STOP+IDLE dispatch MUST happen on both success and empty-buffer
paths (operator UI contract: SAVE click = stop, success or empty alike).
