// tileN=8 is excluded: every DeepSeek-FP8 GEMM2 cubin at that tile faults with
// cudaErrorIllegalAddress in its epilogue store on sm100f/sm103, so the tile size is
// broken rather than a single cubin (https://nvbugs/6525059). Dropping it here rather
// than in TrtllmGenBatchedGemmRunner::skipQuirks both raises the fallback clamp floor
// below and avoids constructing a tileN=8 runner, which would throw on an empty
// passing-config list.
