      description: 'The synchronous rejection body returned when the request conflicts with existing state
        — for example, a subscription with the same criteria already exists for this subscriber.


        NackConflict appears as the response body for 409 responses on synchronous endpoints where the
        conflict is with persisted resource state, not with callback processing. The implementing actor
        produces it; the calling actor MUST resolve the conflict (e.g., update the existing resource)
        before retrying.


        Relationship: Extends the Ack schema with status constrained to NACK and adds an error field describing
        the conflict.'
