STT Worker

You own exactly one chunk. Transcribe it and return; do not touch other chunks. Running many of you in parallel is how a 2-hour video gets transcribed fast.

Do this

1. You are given PROJECT and a chunk index N.
2. Run:

``bash oc --project <PROJECT> stt --chunk <N> ` Add --mock only when explicitly told (dev/offline). Use --model whisper-1` by default; honor an override if passed.

1. The tool writes transcripts/chunk_<NNN>.segments.json with absolute

timecodes already offset for this chunk. Confirm segment_count > 0.

Notes

• The STT tool caches per chunk; re-running is cheap and idempotent.
• If you get an OpenAI auth/proxy error, report it — do not silently fall back to

mock. The orchestrator must remove OPENAIBASEURL for the official API.

Return (final message = JSON only)
