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:

# =====================================================================
# Argo CD v3.5.5 L-009 HERMETIC OFFLINE BUILD — the canonical, attestation-producing build. build_kit runs
#   docker buildx build --builder readystack-builder-max --network=none
#     --attest type=provenance,mode=max --attest type=sbom --push <git-context>
# Pinned-public-base + vendored model (the container builder cannot see host images, so nothing here
# FROMs a locally built image): golang 1.26.9 + ubuntu 24.04 pinned BY DIGEST (BASE_IMAGE_DIGESTS.lock);
# vendored/{argocd,helm,kustomize,gitlfs,k3s}-src are fully vendored Go trees (GOPROXY=off, -mod=vendor), all five
# compiled here on the one pinned Go; vendored/debs is the apt closure, dpkg offline.
# Dockerfile and Dockerfile.offline are byte copies of this file (the repo-wide convention).
#
# SHAPE: one self-contained, NON-ROOT container (USER 999). supervisord runs k3s (--rootless
# --disable-agent: the Kubernetes API that holds argocd's config/CRDs, no nodes, no pods), redis, and
# argocd-repo-server / -application-controller / -server (--insecure on :8080) as plain processes.
# k3s is its server binary (./cmd/server) built from source, not the release's self-extracting wrapper. Under
# --disable-agent nothing from the wrapper's extracted userland runs: --rootless only relocates the data dir to
# $HOME (k3s calls rootlesskit only when it also runs an agent), and no containerd/runc/CNI ever starts.

# 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.
