Unit 3. Verbatim move of 'FFmpeg locator', 'Live encoder + RTMP push',
'Local recording' and 'Live audio capture' into docs/ai/output.md, grouped as
encoder / recording / audio with a 'Related' footer.
ai.md's stub keeps the decisions that must not be re-litigated or rediscovered:
ffmpeg is bundled (never download/fetch; no-network test), args pure and no -re,
probe order NVENC->QSV->AMF->OpenH264 and never libx264, REC/ON-AIR radio-
exclusive by creator ruling, a modal's falsy result must never fall through into
its side effect, full StopStream teardown on every failure, audio pipe closes
BEFORE the video pump, and honest-by-measurement audio (true dBFS meters,
SpeechLeveler + -1 dBFS limiter, live Func gains).
- ai.md Services row and one 'FFmpeg locator section above' pointer repointed;
MyMistakes.md dead-Pin entry repointed.
- docs/ai/index.md gains the output.md row.
ai.md 1,558 -> 1,289 lines. No source touched; no push.
