Round-three diagnosis from the three-machine logs: the console
channel connected first try on SDR both ways - then died seconds
later with end reason 5010 (PeerSentNoConnection). Cause: the arcade
engine closes its console LISTENER the moment the console connects
(correct under TCP, where accepted sockets outlive the listener), but
Steam''s CloseListenSocket closes all accepted connections
ungracefully. The members silently killed their console connection at
accept; the owner''s next packet got no-connection back, no eggs were
ever fed, and all three pods sat waiting.
The transport now bridges the semantics: an engine close only marks
the listener (new callers are rejected, pending queue dropped); the
Steam socket is destroyed in Cleanup at mission teardown. Re-listening
on the same engine port reopens the marked listener.
The loopback self-test now covers exactly this: accept, close the
listener, then push data both ways over the accepted connection -
PASSED (ping 1, survives listener close 1).
