web/moq: the WebSocket binding's capsules, WebTransport and the binding behind one transport interface (WebTransport first, offering moqt-22 and the relay's certificate hash; the binding as the fallback, or forced), a MOQT session (SETUP with the token, requests, every data stream read concurrently, GOAWAY), and the payload framings a WAI track carries. web/room: the room client (WebCodecs publishing with receipts, verified subscriptions, a late joiner's FETCH, the composed canvas and the mixed AudioWorklet, the events timeline and captions with their origin, the move after GOAWAY). web/compose: the composition corpus in the page. e2e: the relay on loopback from a test configuration, real Chrome through Playwright with a fake camera and microphone, each browser under memguard.
