  title: Rigetti Provision Endpoint and Engage
  summary: Create a private endpoint for a processor, poll until it reports healthy, then create an engagement against it.
  description: >-
    Teams that want a dedicated entry point to a quantum processor provision
    their own endpoint rather than sharing the default. This workflow creates an
    endpoint bound to a processor, polls the endpoint until it reports healthy
    (newly provisioned endpoints take time to stand up), and then creates an
    engagement against it so the team can execute. The poll loop retries the get
    call while the endpoint is still coming up. Every step spells out its request
    inline so the flow can be read and executed without opening the underlying
    OpenAPI description.
