  title: WordPress Assign Post to Author
  summary: Resolve a user by role, confirm them, and publish a post under their byline.
  description: >-
    An editorial-attribution pattern that publishes a post under a specific
    author. The workflow lists users filtered to a given role, branches on whether
    any were returned, reads the selected user to confirm the account, and then
    creates a published post whose author is set to that user id, finally reading
    the post back to verify the byline. Each step spells out its request inline,
    including the application password authentication WordPress requires for
    writes, so the flow can be read and executed without opening the underlying
    OpenAPI description.
