# Authoritative build inputs — karmic-kraken (local-inference-lab vLLM fork)
# clean build. Provenance: sparkring dev-20261001-kraken-cuda1342-nccl2323-status034
# (build-metadata.yaml: vllm ab86b7073, b12x e4084d2e, flashinfer 36ad74ad).
#
# Every entry is a tag, exact version, branch-name at a pinned commit, or a
# verified tree hash — no :latest, no ranges, no floating tips.
#
# Reproducibility contract (clone-at-pin, NO staged tarballs): the Dockerfile
# clones every source at the pins below inside the build and GATES each one
# (HEAD commit + tree hash must match, pinned deps must appear verbatim in the
# tree's cmake). A fresh clone of this repository + `bash build.sh` reproduces
# the image.
