Round seven was the first complete Steam race: three machines, five
minutes, wall deaths respawning, the console ending the race on time,
and rematches launched from the same lobby. The one gap the run showed:
only the owner saw scores - members went straight back to the room.
The owner now publishes its console results (host, score, name, keyed
by the race nonce) into lobby data right after teardown; members pull
the sheet (waiting up to 8s for it to land), inject it into the local
results intake, and the same RACE RESULTS screen shows on every
machine before the room.

RPL4LOBBY implements the multiplayer front door on ISteamMatchmaking.
The setup menu grows HOST STEAM RACE / JOIN STEAM RACE buttons when
the Steam wire is live; hosting creates a tagged public lobby, joining
finds one. Every member publishes FakeIP + fake ports + persona +
loadout as member data; the room screen lists members (host marked)
and gives the owner a launch button.
Launching writes a nonced go-roster into lobby data. Each pod
registers every peer with the Steam transport (two-port peer table:
engine console/game ports map to Steam fake ports on connect) and
enters the race: the owner through the hosted-race path - it builds
the multi-pilot egg from real personas and loadouts and its console
marshals everyone - and members as network pods that boot straight
into WaitingForEgg for the owner to feed over the wire.
The lobby outlives races: members loop back through WinMain into the
room (no local console needed - MissionCompleted is waived for member
races), and the owner returns to the room after its results screen.
Leaving the lobby clears the hosted-race priming.
Verified on this box: menu buttons appear under RP412STEAM=1, hosting
creates a lobby on the Steam backend, the room runs and leaves back to
the menu; single-player cycling and the LAN hosted race both still
pass. Full three-account mesh test is next, on real hardware.
