Read-only final state. Only reachable from Disabled. Cannot be re-activated.
STATUS archivedArchived is a terminal, read-only status that preserves the pipeline's metadata and execution history for audit purposes while preventing any further modification or execution. A pipeline can only be archived from the Disabled status; attempting to archive from any other status returns a validation error. Once archived, the pipeline cannot be re-activated, paused, or returned to Draft. This status is intended for end-of-life pipelines that must be retained for compliance or historical reference but should no longer appear in active workflow listings.
