GLM-5.2 Fused MoE Gemini 3.8 Flash (High)

audit verdict: contamination

Isolated regrade 0.0918 (in-run 0.0918). Real fused MoE: device histogram/scan/scatter routing, row gather, fused SiLU*mul, weighted fp32 atomic scatter-add, authored streaming-GEMV decode kernels for T=1; the three prefill GEMMs are cuBLAS (cublasGemmGroupedBatchedEx and at::mm), same class as the grok cells. But before writing any code the agent read the audit corpus for this problem: grepped all 22 prior peak_fractions in results/annotations, located the 0.2787 top scorer by grep -l, opened that annotation and the glm-5.3 one in full, then went straight to the mma.sync instruction those annotations quote. No outputs/runs archive was touched, so kb contamination reports clean; this exclusion is manual. Overwrite probe on a quiet GPU 2026-09-03: cos(out1,out2)=-0.0001 after in-place input overwrite, cos(ref,sol)=1.0000; in-place weight overwrite 0.0000 / 1.0000.
