- core/webrtc: NewSourceOn(streamID, host, port) allows binding the
RTP UDP socket on something other than 127.0.0.1, required when the
PoC runs in a container and must accept RTP from LAN publishers.
NewSource(streamID, port) stays as a convenience wrapper on
127.0.0.1 for existing tests and tight local tests.
- cmd/webrtc-poc: new -rtp-host flag (default 127.0.0.1 for safety).
- deploy/docker/Dockerfile: two-stage build, scratch runtime, ~14 MB.
- deploy/truenas/docker-compose.yml: host-networked stack template
driven by a .env file. Host networking is required for WebRTC ICE
to work without NAT rewriting per-candidate.
- deploy/truenas/README.md: operator runbook with port picking,
bring-up, verification curls, and security notes.
