Canonical VOWL experimental candidate: 2026-10-04-cutover-01 The canonical package and profile checkpoint is identified by manifest SHA-256: 43cd3c7c6f7d412552ed9cddc8f04866a89eb74eeb95e4544e3665238931224e This application revision promotes the qualified canonical controller, retires legacy writers and preserves the named legacy migration adapter. It does not change canonical package bytes or establish a permanent /v1 interoperability promise. Future candidates may correct errors with explicit revision and compatibility information. Retain original ontology sources for recovery. The application operator retains the exact deployed-file inventory and hashes alongside its qualification and rollback records. The checkpoint identifies the package/profile materials; it is not the application build digest.
