Vendored patches — provenance

model.patch, modelopt.patch, sparse_attn_indexer.patch, sparse_attn_indexer_kpool.patch: unmodified copies from FujitsuPolycom/glm53-flash-tp2-spark (master @ vendoring date 2026-08-27), Apache License 2.0. See their THIRD_PARTY_NOTICES.md as well. Verified to apply with zero fuzz against vllm/vllm-openai:glm53-flash-arm64-cu130.

patch_mla.py: the NoPE-MLA / sm120 sparse-MLA mod from kingjones30/GLM-5.3-Flash-2x-DGX-Spark (see also docker-images/glm53-flash-nvfp4/).

Not vendored from FujitsuPolycom: image/patches/glm5next-kda.patch (requires their base's chriswritescode SM120 overlay; enables --kda-prefill-backend flashkda), image/patches/renderers-base.patch (multimodal renderer; we serve --language-model-only), and image/nccl/libnccl.so.2.30.7 (direct-cabled-ring fabric; our clusters use the stock NCCL with per-cluster [nccl.*] config).
