ed25519: documents RFC 8032 byte-equal Metal verify kernel (100 vectors) + N_threshold = 256 on M1 Max with 26.7x speedup at N=4096 vs equivalent- shape CPU port. dGPU CUDA port pending in lux/crypto/ed25519/gpu/cuda/. mldsa: documents structural-skeleton M1 kernel + dGPU residual. Per-thread serial work on Apple Silicon (~122 us SHAKE256-dominated) vs ~42 us NEON narrows expected M1 wall-clock speedup to ~7x at N=4096; CUDA H100/Ada closes that gap (~33x ceiling). mlkem: same shape as mldsa, ~75 us per-thread Metal vs ~26 us NEON. SHA3/SHAKE256 chains are the M1 ceiling; dGPU port closes it.
