nx_game_room_gate.nx

nx_game_room_gate.nx -- proves the UNIFIED game+comms room: one sovereign room (one room hash) carries MANY independent channels over nx_room_relay -- player-state (game), chat (text), audio (PCM), video (frames) -- all server-relay, NO WebRTC/STUN/ TURN/WebSocket. This is the keystone of "do video OR audio OR chat OR all, in the game": join one room, opt into whichever channels you want. Each channel = its own relay instance keyed by the SAME room hash, so they coexist by construction. 1) UNIFIED: a peer in the room reads game-state + chat + audio + video for the room 2) SELECTIVE: a chat-only peer appears in chat roster but NOT in audio/video (opt-in) 3) ISOLATION (neg): a peer in another room sees none of these channels 4) NO CROSS-CHANNEL BLEED (neg): each channel carries only its own payload 5) anti-tautology / ghost (neg): distinct rooms carry distinct state; ghost absent Built nx_cc_sovereign -> nxasm_x86 (no gcc, no .sh). Reuses nx_room_relay + nx_pets_netstate. license_tier: ORIGINAL
