  title: Oracle OCI Stop Compute Instance
  summary: Read an instance, send the STOP action, then poll until it reports STOPPED.
  description: >-
    Gracefully powers off a running compute instance and confirms the shutdown
    completed. The workflow reads the current instance to capture its ETag for
    optimistic concurrency, issues the STOP instance action guarded by that
    ETag, and then polls getInstance until the lifecycle state becomes STOPPED.
    Every step spells out its request inline so the flow can be read and executed
    without opening the underlying OpenAPI description.

  summary: Stop a running compute instance and confirm it reaches STOPPED.
  description: >-
    Reads the instance, performs the STOP action with an if-match guard, and
    polls the lifecycle state until the instance is STOPPED.
