//########################################################################
// The local console runs on ITS OWN THREAD, like the real console: it
// stays alive across the whole session, owns the mission clock, and
// raises the stop request when the selected length expires. The game
// thread's per-frame tick is the only place engine calls happen - it
// reports state transitions to the console thread and executes the
// requested StopMissionMessage dispatch (the engine is single
// threaded; cross-thread dispatch is not safe).
//
// NETWORK RACES (lobby owner as console): the same tick additionally
// marshals REMOTE pods over the NetTransport wire, speaking the exact
// arcade console protocol - egg chunks + ACK, state queries,
// RunMission when everyone reaches WaitingForLaunch, StopMission at
// expiry, EndMission score intake. The owner's own pod runs in
// network mode (it meshes like any pod) but is fed its egg locally
// and driven by direct engine calls, so the console never needs a
// connection to itself.
//
// Results flow in through gConsoleScoreSink (RP layer) for the local
// pod and EndMission wire messages for remote pods: the same final
// scores every pod sent the arcade console at mission end.
