  title: Rigetti Cancel Reservation
  summary: List a user's reservations, inspect the most relevant one, and cancel it, confirming the cancellation.
  description: >-
    Managing booked QPU time often means cancelling a reservation that is no
    longer needed. This workflow lists the caller's existing reservations
    filtered to a single processor, branches when none exist, otherwise reads
    the first matching reservation to confirm its details, and then cancels it.
    Because the cancel call returns the updated reservation, the flow can assert
    the cancelled flag without an extra read. Every step spells out its request
    inline so the flow can be read and executed without opening the underlying
    OpenAPI description.
