  title: GitHub Actions Collect Workflow Run Artifacts
  summary: Find the latest run for a repository, confirm it, list its artifacts, and resolve a download URL.
  description: >-
    Retrieves build outputs produced by a workflow run. The workflow lists the
    repository's runs to select the newest one, fetches that run to confirm it,
    enumerates the artifacts attached to it, and finally requests the artifact
    archive download which the API answers with a 302 redirect to a short-lived
    download URL. Every step spells out its request inline so the flow can be
    read and executed without opening the underlying OpenAPI description.
