Vanadium forbids direct UDP for WebRTC, and mobile and company networks often block direct connections; the only route then is a relay reached over TCP. - server/turn.ts: STUN and TURN on one port, over UDP and TCP, with short-lived credentials from /api/turn, quotas and a peer filter - The browser build fetches credentials and offers the relay automatically - Stats for nerds says when a stream is relayed and how the relay is reached - Tests: a TURN client over UDP and TCP, and a browser limited to the relay over TCP in the web E2E Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
