 ## Upcoming Next Actions
 - [x] Backend endpoint for audio upload `/api/media/audio` (accept WebM/PCM) — implemented with MinIO via AWS SDK v3
 - [x] S3-compatible adapter using MinIO (`S3_ENDPOINT`, `S3_ACCESS_KEY`, `S3_SECRET_KEY`)
-- [ ] Backend STT endpoint `/api/stt` (download from MinIO, call OpenAI STT, return transcript)
-- [ ] Add STT trigger in UI: call `/api/stt` with `{ bucket, key }` and render transcript
