SWAG 5.9.0 build recipe

The recipe ReadyStack built readystack/swag:5.9.0-CE-ubuntu24.04-r1 from: the upstream source it starts from, every pinned input, and the files that run the build with the network off. Public here: the source and commit, the pinned inputs, all 26 recipe files with their sizes and SHA-256, 9 of them public in full or in part, and the opening lines of the Dockerfile and build script.

# GENERATED L-009 hermetic Python build (--network=none, SBOM+SLSA-attestation-producing).
# Pinned base from BASE_IMAGE_DIGESTS.lock; vendored wheelhouse + source + debs from Dockerfile.vendor.
# pydeps sub-stage installs the wheelhouse offline; COPY /deps /usr/local keeps pip OUT of the runtime SBOM.
# CPython 3.12.16 COMPILED HERE, offline, from python.org's tarball (sha256 re-checked) and the vendored
# build debs, by the same command the vendor stage ran; linked against Ubuntu's libraries (debs the scan
# sees, apt fixes). The runtime takes /usr/local from this stage and none of the toolchain.

# =============================================================================
# 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.

#                                     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
