  title: Azure DevOps Queue and Monitor a Build
  summary: Queue a build, poll until it completes, and fetch its timeline.
  description: >-
    Queues an Azure Pipelines (classic) build and follows it to completion. The
    workflow queues a build for a definition with an optional source branch
    override, polls the build by ID until its status reaches completed (looping
    back while it is still in progress), and then fetches the detailed timeline
    so callers can see which phases, jobs, and tasks passed or failed. Every step
    spells out its request inline so the flow can be read and executed without
    opening the underlying OpenAPI description.
