  title: Apigee Registry Spec Revision Rollback
  summary: Read a spec's current revision, push a new revision via update, then roll back to the original.
  description: >-
    The Apigee Registry spec versioning flow. The workflow reads a spec to
    capture its current revision id, updates the spec contents to create a new
    revision, and rolls the spec back to the originally captured revision —
    demonstrating safe spec change and recovery. Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
