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:

# GENERATED L-009 hermetic Node build (--network=none, SBOM+SLSA-attestation-producing).
# Pinned base from BASE_IMAGE_DIGESTS.lock; vendored resolved /app tree + debs from Dockerfile.vendor.
# NO install verb offline — the fully-resolved, prod-pruned node_modules is COPYd verbatim.
# source.runtime_node false: Node built the static output in the vendor stage; the runtime serves
# source.app_copies and has no Node (vendored/node/ records the build's Node, it is not installed here).

# 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.
