Patch 0009 lowers half-to-e4m3 (plain and ReLU) through hardware packed FP8 conversion on gfx12 with explicit saturation and sign restoration; patch 0010 keeps native FP8 operands packed through the NVIDIA-to-WMMA lane gathers. Same-runtime software control 33.90 ms vs native 26.28/26.65 ms; packed gathers bring the twenty-frame run to 25.33 ms, all frames byte-identical.
