- NSDMI null/-1 defaults for AttentionParams/FP8Params pointer+flag members: partially packed structs can no longer hold garbage non-null pointers that gate optional paths (root cause class of the paged test bug); still aggregates, still trivially copyable
- move per-lane ldmatrix wrappers (ldsm_x2/x4) from fp8/gemm.cuh to common/mma.cuh as ldmatrix_x2_lane/x4_lane, next to the single-address variants
- DEVICE_FORCEINLINE macro in common/mma.cuh (matches layout_policies.cuh, internal linkage)
- frag_addr now delegates to tile_at: the swizzle math has one source
- operand layouts as CUTLASS-style RowMajor/ColMajor tags threaded from launch_fp8_gemm through the kernel to load_operand_tile; B's operand view via transpose_layout_t; call sites read <Fmt, false, RowMajor, ColMajor> instead of <Fmt, false, false, true>
