  title: Cellulant Payout, Query, and Refund
  summary: Disburse a payout, query its outcome, and reverse it with a refund when the payout did not succeed.
  description: >-
    Adds an automatic reversal path to a Beep disbursement. The workflow posts a
    payout with BEEP.postPayment, queries the outcome with BEEP.queryPayment,
    and branches: when the query reports the payout pending (status code 139) it
    issues a refund with BEEP.refundPayment, and when the payout succeeded it
    ends. All three steps call the single bare postPayment operationId,
    discriminated by the function field, and inline the Beep Basic Authorization
    header alongside the payload credentials.
