One socket on :7700 carries hello, heartbeats both ways (5 s timeout), 5 Hz state snapshots of envelopes, and idempotent commands. 'mark' is forwarded to the recorder's control socket. --mock synthesises degrading state flagged as mock in every envelope; without it a client gets hello and heartbeats only. Peers outside loopback, RFC 1918 and the tailnet are refused. Deployed on the car Orin as yukart-gw.service.
