--/**
-- * The worker interface for the transports OpenRe does not carry yet. Today only WebRTC: the port
-- * (WHIP ingest + mediasoup SFU + viewer signaling) is T4's next job (decision 1, one worker owns
-- * all of it). It registers a generation with the coordinator, takes part in the drain protocol and
-- * heartbeats like a real transport worker, and carries nothing: activeCount() is always 0, and no
-- * 'webrtc' session is ever admitted (a definition may list the protocol, but its HTTP error is
-- * 'protocol_not_allowed' — no worker accepts it, so encoders keep using Live).
-- *
-- * This is the seam the port lands in: it replaces `admit nothing` with its session code and reports
-- * sessions through store.sessions exactly like rtmp-ingest.js / jsmpeg.js.
