Protocol v2 + amendment 1 (FP32 only, 180 MB / 45 ms budget). SC passes all gates on DEV2 and on FINAL2 (opened once) for seeds 42/43/44. Amendment written after DEV2; runtime uncalibrated. v1 INT8 variants unchanged. See benchmarks/v2/README.md.
Original, control A and experimental B; CPU exports, optional FP32 reference checkpoints, text-free evaluation records and bilingual documentation. B remains experimental: composite criterion failed; FINAL not evaluated.
