  title: Buildkite Fetch Job Log
  summary: Read a build, pick a finished job, and fetch its log output.
  description: >-
    A log-retrieval flow for surfacing the raw output of a specific job. The
    workflow fetches a build by number, captures its jobs array, and then fetches
    the log output for the supplied job UUID. This is the building block for
    pushing Buildkite job logs into an external log store or attaching them to an
    incident. Every step spells out its request inline so the flow can be read
    and executed without opening the underlying OpenAPI description.
