  title: Amazon EBS Detach and Delete Volume
  summary: Detach an EBS volume from its instance, confirm it, then delete it.
  description: >-
    A teardown counterpart to the provisioning flows, adapted to the EC2-style
    EBS operations the spec actually supports. It detaches the supplied volume
    from its instance, reads the volume back to confirm it is no longer in use,
    and then deletes the volume. Every step spells out its request inline so the
    flow can be read and executed without opening the underlying OpenAPI
    description.
