2026-09-27: moe_w8a8_grouped_gemm_pm4 on the native e4m3 tensor-core MMA (the _gu or _dn entry, described by tile): same operands and output, bit-identical, over a work-list that moe_build_tile_worklist built on the same stream with tile.m_tile and n / tile.n_tile. grid_ctas (clamped to 1..=16384) CTAs stride over the items.
