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>

// L4STEAMNET -- the Steam internet transport (BT_STEAM only).

|
|
// ISteamNetworkingSockets with FakeIP + SDR behind the L4NET.CPP wire
|
|
// seam: connections carry the engine's exact TCP byte stream as reliable
|
|
// Steam messages, re-assembled into per-connection rings so the engine's
|
|
// nonblocking recv semantics hold (empty -> WSAEWOULDBLOCK, peer-closed
|
|
// -> 0). Handles are pseudo-SOCKETs (0x5EA0xxxx) so L4Host and every
|
|
// call site above the seam are identical on both wires; the peer address
|
|
// reported through CheckSocket is the peer's FAKE IPv4:port, so the
|
|
// engine's roster matching works against a lobby-built egg whose
|
|
// [pilots] carry FakeIPs.
|
|
//
|
|
// Install: env BT_STEAM_NET=1 (set by the lobby launch path) -- needs the
|
|
// Steam client running and content\steam_appid.txt (written with the 480
|
|
// Spacewar test id if absent). Everything degrades gracefully: no Steam
|
|
// -> inactive -> pure Winsock.
|
|
//
|
|
// Ports: FakeIP port index 0 = the CONSOLE channel, 1 = the GAME channel
|
|
// (mirroring the arcade console-port / game-port=console+1 convention).
