nx_gx7_game_gate.nx -- Gx-7: the first playable becomes an actual GAME. The walk gate proved locomotion; this adds the three things that make it a game rather than a camera demo: ENTITIES that exist in world state, COLLISION that changes that state, and a WIN CONDITION the player can actually reach. The full loop, every tick: input -> player state -> COLLISION RESOLVE (world state mutates) -> build the player-relative mesh (terrain bands + only the entities still alive) -> nx_swgpu -> HUD overlay -> canvas blit -> live browser repaint. The render is a PURE FUNCTION of game state, so "it vanished when I picked it up" is a rendering fact, not a separate animation to keep in sync. Still DETERMINISTIC end to end: the same script replays to byte-identical frames INCLUDING the collision outcomes. license_tier: ORIGINAL expect_exit: 0
