  title: Google Cloud Dataflow Cleanup Job Snapshots
  summary: List snapshots for a job, inspect the oldest one, then delete it.
  description: >-
    Reclaims storage by pruning snapshots created from a specific job. The
    workflow lists the snapshots in a region scoped to a source job, captures the
    first snapshot id, reads that snapshot to confirm its state and creation
    time, then deletes it. Every step spells out its request inline, including
    the inline Bearer authorization Google Cloud requires, so the flow can be
    read and executed without opening the underlying OpenAPI description.
