# NackDiscretionary — v2.0

The synchronous rejection body returned when a responding NP exercises its protocol-level agency to decline engagement for policy-governed reasons — insufficient caller trust, capacity limits, scheduled inactivity, or general refusal — without an underlying exception in the received message. The caller MUST NOT expect an on_* callback.
