2026-09-25: Contiguous block-scaled W8A16 GEMM, tile chosen by w8a16_pipelined_prefers_m32: the 32-tile twin on m32_kernel, else (2026-09-26) w8a16_pipelined_prefers_m64’s 64-tile twin on m64_kernel, else the 128-tile w8a16_gemm_pipelined on full_kernel. The GDN in_proj_qkvz / out_proj batched-verify arms (trait_decode_batched.rs) call it.
