nx_mp_daemon_gate.nx

nx_mp_daemon_gate.nx -- proves the sovereign multiplayer daemon request-handler (nx_mp_daemon) over a relay. NO sockets, NO js, NO curl: crafts real HTTP request bytes and drives mpd_pstate / mpd_roster directly. 1) routing: /pstate->1, /roster->2, a file path->0 ; query ints parsed 2) POST /pstate puts the body snapshot into the room (two players) 3) GET /roster returns an HTTP response whose body = the OTHER players' [len][frame] records (byte-exact) 4) room isolation (neg): /roster for a different room returns an empty body Built nx_cc_sovereign -> nxasm_x86 (no gcc, no .sh). license_tier: ORIGINAL
