nx_game_gate_register.nx

nx_game_gate_register.nx -- GOVERNED registration of the game-engine evidence gate (operator: "keep building the team to build this"). ENGINEER verdict = run the gate twice and require DISCRIMINATION: (a) with the UNFIXED _offc/nx_cc_sovereign.elf the gate must FAIL >=1 module (it must catch the known unterminated-block miscompile via nx_term_kat + nx_tictactoe_test); (b) the gate must judge by RAW wait status (signal-aware) and exit with the fails count -- a gate that can't go red is not a gate. If a FIXED compiler candidate is present at /tmp/nx_cc_fixed_oracle.elf the Engineer also requires it to gate GREEN (fails=0). license_tier: ORIGINAL
