Release engineering from one model

Release engineering is the most-copied, least-governed surface in any multi-repo org: CI YAML pasted between services until no two pipelines agree. ontoref models the entire release surface as one typed NCL workflow layer and generates the real artifacts from it — so the pipeline is queryable like any other architectural fact, and drift fails before it ships. ADR-038 added multi-arch OCI distribution as a catalog entry plus a generator, not a fork.
