nx_sim_film_gate.nx

nx_sim_film_gate.nx -- "do we need blit?" -> NO, not to RENDER. This proves the fully sovereign visual pipeline: our own compiled sim organ runs, our own integer rasterizer draws every pixel, and our own PNG writer (nx_png) emits the frames -- ZERO browser, ZERO JavaScript, ZERO blit, ZERO third-party. It runs nx_gassim natively for K frames, stacks each rendered framebuffer into a tall "filmstrip", and writes ONE PNG of the gas evolving. (The companion nx_gassim_wasm_vm_gate separately proves the SAME logic runs as wasm bytes in our sovereign VM. In a browser TAB a few lines of host glue are unavoidable -- wasm has no DOM/canvas access, so the platform exposes pixels-to-screen only via a JS-bound API; that glue is the browser's, touches zero pixels/logic, and is optional reach. This gate is the path that needs none of it.) GREEN iff 6/6. license_tier: ORIGINAL expect_exit: 0
