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. Your build platform runs
#                                     the build and signs that provenance with a key the build steps cannot reach
#                                     (see REBUILD.md). Any SLSA build level is your platform's; this archive claims
#                                     none. The image digest is the same either way.
#   ./BUILD_OFFLINE.sh --restore-modes   only put back file modes your unpacking changed (see below), then exit
#
# File modes are build input: COPY carries them into the image. `tar -xzf` without -p, as a non-root user, applies
# your umask to every file (664 becomes 644 under umask 022). FILE_MODES.tsv records every file's and directory's
# mode as packed, and every run of this script first puts back any that differ.
