  "description": "Complementary kernel knowledge map for Humanize-driven GPU kernel optimization. Lists code and knowledge repositories that have no curated PR diffs in the local Route A corpus (NVIDIA developer samples, Colfax research kernels, simveit micro-tutorials, Hygon/DCU optimization references); each framework entry points to upstream repos, kernel directories, and source guides. Topic entries map kernel topics to per-framework references for live clone/grep workflows. Frameworks already covered by Route A PR bundles (SGLang, vLLM, TensorRT-LLM, PyTorch, FlashAttention, FlashInfer, CUTLASS/CuTe, CCCL, Triton, DeepGEMM, ThunderKittens, TileLang, QuACK, DeepSeek TileKernels) are intentionally excluded.",
