…figs by topk Measured block×warp sweep (~387 geometries per combo) on 8× MI300X for DeepSeek-V4-Pro (top-6) and Kimi-K3 (top-16) at hidden 7168, EP8. Dispatch: bf16 + fp8_e4m3_fnuz, 7 token counts (64-4096), 2 topk values -> 28 rules (14 per topk). Combine: bf16 x (fp8_direct_cast, none) x zero-copy, 7 token counts, 2 topk values -> 28 rules (14 per topk). All 8 sweeps completed with 0 failures. Co-Authored-By: Claude <noreply@anthropic.com>
