- audio.StemSeparator/StemSeparationProvider: Demucs zip transport via
POST /upstream/<id>/v1/stems (Mode two -> two_stems=vocals; model +
format fields); bounded zip unpack, entry name -> stem, ext -> MIME.
- SFXModel reuses musicgen against the sync /upstream/<id>/v1/sfx route
(JSON prompt/seconds/steps/cfg_scale/seed -> WAV); musicgen.Request
gains CFGScale.
- audio.SpeechEnhancer/SpeechEnhancementProvider:
POST /upstream/<id>/v1/enhance -> WAV (result reuses SpeechResult).
- SpeechRequest.ReferenceAudio/ReferenceMIME (+WithReferenceAudio):
llamaswap switches to the chatterbox clone route
POST /upstream/<id>/v1/audio/speech/upload (input + voice_file),
wav MIME fallback.
- TranscriptionRequest.Translate (+WithTranslate): translate=true form
field, language=auto forced when no explicit hint (whisper.cpp default
en would skip translation).
- httptest contract tests (zip unpack, clone-route switch, translate +
auto-language injection); ADR-0024 (index row deferred — MJ-A backfills
the ADR index table and parallel edits would conflict).
