- frontend types & components now use lowercase codec values (prores/dnxhd/
h264/uncompressed) to match backend CodecType enum. This was the real
cause of the silent Start Recording 422.
- recorder.py: replaced last .done() call on asyncio.subprocess.Process
with returncode-is-None check (same bug previously fixed in hls.py).
This was causing /api/ports/{n} to 500 during active recording and
health checks to fail while any port was running.
- useRecorder now parses pydantic 422 error bodies so field-level detail
reaches the UI, and App.tsx shows a fixed error banner.
- Added docker-compose.truenas.yml: no deltacast device passthrough,
frontend on :8088. Lavfi testsrc2 fallback kicks in automatically and
feeds the full HLS preview + recording pipeline with a test signal
(1080p30 + 1kHz tone). Verified end-to-end on Wooglin: 442MB/1:56s
H.264 MP4 + working HLS playlist.
