about

nx_raster_bench.nx -- ARC-10/S12 PERF RUNG-0: the MEASURED sovereign-rasterizer baseline on the REAL textured-Draw path (txtri_render: 3 edge fns + barycentric UV + 4-tap bilinear nx_txs_sample per fragment -- the realistic pixel workload, NOT a null loop). Hardware clock CLOCK_MONOTONIC, best-of-N reps. NEG-CONTROLS: (a) quarter-pixel scene must take materially less time (the timer tracks the PIXEL workload, kills the synthetic-fps lie); (b) FLAT texture -> uniform fill (the per-fragment sample path is live inside the timed frame). Baseline numbers gate every later rasterizer optimization claim (ratchet). license_tier: ORIGINAL expect_exit: 0
