Sonic MoE Qwen 3.8 Max

audit verdict: contamination

Disqualified for cross-run contamination. Technically, the archived file is a real Triton persistent grouped GEMM with an in-register SwiGLU epilogue, not a vendor wrapper or cached-output answer. result.json and the official checker support correct=true for the frozen three-shape deck, and static review agrees on those exact balanced inputs. No forbidden library dispatch, grader edit, tolerance change, CUDA graph, timing API, or output memoization remains in the final source, so reward_hack=false. However, the pointer-keyed launch-plan cache has a concrete stale-routing defect for mutable or alternating expert_offsets, and reused output storage requires callers to clone results before subsequent calls. The archived 0.0868 timing is also contended. Keep publish_grade=false. A technical isolated regrade may document behavior, but leaderboard eligibility requires a fresh clean-room run without access to prior outputs, solutions, scores, or tuning artifacts.
