An end to end SLSA implementation uses the AMPEL policy engine and the new SLSA 1.2 source track to enforce policies from commit to release: reusable GitHub Actions collect provenance, verifier policies check SLSA level 1 for commits and builder images, transformers merge OpenVEX suppressions into OSV scans, and subject chaining links commits → SBOM → binaries. A demo project called freeto generates signed VSA bundles with provenance, tests, SBOMs and vuln attestations, and the pipeline gates the build — the example runs and publishes verifiable bundles.
