  title: Azure DevOps Complete a Pull Request
  summary: Fetch a pull request, verify it can merge, and complete it.
  description: >-
    Completes (merges) an active Azure Repos pull request safely. The workflow
    fetches the pull request to read its current status and the head commit of
    the source branch, branches on whether the merge status is clean, and only
    then patches the pull request to status completed — supplying the required
    lastMergeSourceCommit and completion options such as squash merge and source
    branch deletion. Every step spells out its request inline so the flow can be
    read and executed without opening the underlying OpenAPI description.
