about

nx_solarsim_gate.nx -- NATIVE verify of the browser solar-system sim (base = mmap; the SAME base-relative code runs in the sovereign WASM). Proves it is REAL physics, not animation: each planet is leapfrog-integrated under the Sun's gravity, and we (1) measure each EMERGENT orbital period (steps to close the orbit) and show the ratios match the REAL measured planetary periods (Kepler T~a^1.5) within 3%, (2) confirm the inner-faster ordering, (3) confirm orbits stay bounded (no spiral/escape) with energy conserved, (4) raster a frame to PNG. This is the "video games are simulators / full real physics" deliverable, browser-ready. license_tier: ORIGINAL expect_exit: 0
