    x-apievangelist-notes: >-
      The original spec declares no operationIds and no application/problem+json
      error responses; errors use a custom {code,error,errorDetails} envelope
      documented at docs.hifi.com/api/errors. Idempotency is client-driven via a
      requestId body field. Gaps to raise with the provider: add operationIds and
      formalize the error schema in-spec.
