Critical fix based on commit 41ecb8c's discovery: enginex-vllm-bi100-qwen36 has NO .cu source files. All 9 csrc/*.cu injection targets in VLLM_INJECTION_POINTS are dead — patches generated by gen_patch.py have zero effect on the running system. Old (DEAD): reduce → csrc/attention/attention_kernels.cu (does not exist) topk → csrc/sampling/sampling_kernels.cu (does not exist) scan → csrc/attention/paged_attention_v1.cu (does not exist) ... etc New (REAL): prefill → prefix_prefill.py BLOCK/NUM_WARPS (Triton JIT tl.constexpr) flash_attn → triton_flash_attention.py BLOCK_M/BLOCK_N (Triton autotune) moe → fused_moe.py BLOCK_SIZE_M (only param ixformer reads) runtime → _custom_ops.py SMEM (48KB fix) scheduler → computility-run.yaml num-scheduler-steps Dead targets preserved as comments for documentation.
