This delivers that sovereign + open. tools/buildpack.py: - detect(): which Paketo buildpack matches the source (requirements.txt/package.json/go.mod/ Cargo.toml/index.html) — no Dockerfile. - build_plan(): CNB `pack build` model — detect -> reproducible OCI image (content-addressed over source+buildpack; same source -> same image) + Procfile-style process_types + the real pack command. Fail-closed: no match -> refuse, don't guess. - deploy_workload(): the built image -> a workload the executor dispatches (service=Deployment, worker=Job); the sandbox is the per-branch preview, the promotion gate is dev->prod.
