docs(01-09-save-stops): debug record — RED → GREEN → A14 evidence + closure notes
Updates .planning/debug/01-09-save-stops-recording.md with:
- status awaiting_human_verify
- SHA references (red_commit cd83eb0, green_commit 4f4c3e2, a14_commit 2b6c24b)
- Verification evidence (98/98 unit GREEN, 15/15 UAT GREEN, tsc+build clean)
- Vitest + UAT output snippets
- A14 design rationale
- Noteworthy: no PortMessage/Message changes (STOP_RECORDING already
in MessageType + offscreen handler already wired); resetBuffer
intentionally NOT called by SW post-save (offscreen.stopRecording
deliberately omits it; next session's startRecording handles it);
empty-buffer trade-off (brief recovery notif in production, badge
still resolves to OFF — documented inline in src/background/index.ts).
