"""Phase 4 integration tests: System Audio and Mic capture WebSocket endpoint.

Covers:
- WebSocket handshake with UUID-format video_id (no actual video file)
- source=system-audio connection accepted with language param
- source=mic connection accepted with language param
- Config toggles disable both system-audio and mic features

Uses FastAPI TestClient with real router. Only external DashScope ASR is
implicitly avoided (client disconnects before proxy call completes).
