nx_gsplat_tile_gate.nx -- GATE for the tiled rasterization policy. ★★THE ACCEPT RULE WAS DECLARED IN THE ORGAN'S SOURCE BEFORE THIS GATE WAS RUN, and this file only enforces it: CORRECTNESS -- the tiled frame is BYTE-IDENTICAL to the full-screen frame. An optimisation is allowed to change cost and NOTHING else. "Close enough" would mean the two renderers had quietly become two rulers. COST -- strictly fewer conic evaluations on a scene with real occlusion. T4 is the honest counterweight: on a scene with NO occlusion the policy must save NOTHING and still be byte-identical. A win that appears on every scene regardless of occlusion would mean the saving came from somewhere other than the mechanism claimed, and that is the failure this tooth exists to catch. T3 replaces the question "what tile size?" with a MEASUREMENT. The organ names no favourite edge; the gate sweeps a doubling series and publishes evaluations and list occupancy at each, and requires byte-identity at EVERY size. A constant nobody measured would have been the alternative. license_tier: ORIGINAL expect_exit: 0
