nx_play_parity.nx

nx_play_parity.nx -- the NATIVE GAME-PARITY TESTER (operator: "build a native tester in the nishi ecosystem ... like how google plays games, you could tell if it really is the same as a game we are competing against"). A SOVEREIGN agent that PLAYS a Nishi game (drives real inputs + reads real game state -- NOT a unit-gate checkbox, NOT 3rd-party playwright) and measures it against a named COMPETITOR capability-by-capability, producing an honest PARITY SCORE + the missing-capabilities list. This V1 targets the tactics engine (nx_tactics_engine_lib, cleanly native-drivable) vs XCOM / Into the Breach. Each capability is a PROBE that actually does the action and verifies the effect. Crucially it also probes a capability the game is KNOWN to LACK (fog-of-war) so the score is honest and the tester is proven non-rubber-stamp (the self-gate requires the absent capability to come back ABSENT). SELF-GATE (no args): PLAY-PARITY-GATE verdict=GREEN iff the tester is HONEST -- all 7 known-present capabilities detected PRESENT and the known-absent one (fog-of-war) detected ABSENT. The PARITY SCORE (7/8 -- same core, missing fog-of-war) is the OUTPUT answer to "is it really the same as XCOM".
