Fetched once, with the network on, by the vendor step (Dockerfile.vendor) when the kit was made; the offline build uses the kit's vendored copies:

# ReadyStack — offline reproducible rebuild.
#
# Rebuilds this product's image from THIS ARCHIVE ALONE, with no network access
# of any kind, and prints the resulting linux/amd64 image-manifest digest.
# Run ./VERIFY_OFFLINE.sh afterwards to assert it equals the published digest.
#
# Requirements: linux/amd64 Docker host, docker buildx >= 0.30, jq, tar.
# No git, no registry access, no additional tooling.
#
#   ./BUILD_OFFLINE.sh                the rebuild (OCI image + a docker-loadable copy)
#   ./BUILD_OFFLINE.sh --provenance   the same rebuild with SLSA v1 build provenance (mode=max) attached to the OCI
#                                     image, generated by BuildKit, not by any build step. Run on your own hardened,
#                                     isolated build platform and sign that provenance with a key the build cannot
#                                     reach, and the result meets SLSA Build Level 3 (see REBUILD.md). The image
#                                     digest is the same either way.
