NEW gated (BT_STEAM) game/glass/btl4lobby: an ISteamMatchmaking room replacing the arcade Site-Management screen -- host creates (lobby data btl4=1), members join by filter, pilots publish name/mech/color, the host ENTER mints the roster and signals GO. THE FAKEIP LESSON (live-verified, prior-art assumption DISPROVEN): a fresh process gets a DIFFERENT FakeIP, so menu-time fake addresses go stale by mission time -- the first cycle timed out connecting to its own stale address. Redesign: roster addresses are opaque ipv4-shaped TOKENS (169.254.77.N with ports 1501/1502) minted by the host at GO, mapped to Steam IDENTITIES; connections ride ConnectP2P(identity, channel) with console=0/game=1 virtual ports; the map reaches mission processes via env (BT_FE_MYFAKE + BT_FE_STEAMMAP); the GetMyAddress seam feeds the pod its own token for roster self-match; CheckSocket reports peers by token. L4STEAMNET reworked (no FakeIP allocation at all); the marshal gained the Steam-wire branch. Verified single-machine (ON/ON, live Steam): menu -> HOST STEAM LOBBY -> room -> GO -> token map minted -> egg roster carries the token -> mission process up with 1 roster token incl. self -> pod self-matches -> stock console ladder -> mission RUNS (46 ticks). Remaining: the live 2-account cross-machine session (docs/STEAM_TEST.md). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

// btl4lobby -- the Steam lobby (BT_STEAM only): an ISteamMatchmaking room
|
|
// replacing the arcade Site-Management screen for internet MP testing.
|
|
//
|
|
// The MENU process runs the lobby (the Steam transport is installed there
|
|
// first, so each member's FakeIP is known): members publish their fake
|
|
// address/ports + pilot identity as lobby member data; the host's room
|
|
// screen lists members and its ENTER writes the GO signal; everyone then
|
|
// relaunches into the mission -- the host with the marshal armed against
|
|
// the members' fake CONSOLE addresses, members as plain -net pods with
|
|
// BT_STEAM_NET=1 waiting to be fed over the Steam wire.
|
|
//
|
|
// Known limitation (documented): the lobby object does not survive the
|
|
// per-mission process relaunch -- after a mission everyone re-joins from
|
|
// the menu. FakeIP stability across the immediate relaunch is assumed
|
|
// (Valve persists assignments per app+account); the live 2-account test
|
|
// is the step's exit criterion (docs/STEAM_TEST.md).
