- 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).
