about

nx_simlab_gate.nx -- NATIVE eyeball+physics verify of the browser sim-lab (base = mmap). This is the SAME base-relative integer code that runs in the browser (base = 0 = sovereign WASM linear memory); with no browser in-harness, the native render-to-PNG + physics asserts ARE the proof the wasm logic+raster are correct (the established "verify wasm by native PNG" loop). Runs the orbit in leapfrog (must stay bounded + conserve energy) then in Euler (must drift/spiral) and writes both frames to PNG. license_tier: ORIGINAL expect_exit: 0
