+===== Discussion =====
+An Event Producer Role identifies a Logical Node's responsibility for producing an event that reports an occurrence, observation, state change, decision, or result.
+Events support loosely coupled information exchange. An event records that something occurred or that a Logical Node observed, derived, decided, or changed something. An event differs from a command because it reports an occurrence rather than instructing action.
+A Logical Node performing an Event Producer Role identifies the event, the Logical Data Structure Definition, the Runtime Plane, and the expectations for provenance and traceability.
+===== Definition =====
+//Communication Role responsible for producing an event through a Logical Communication Endpoint.//
+===== Source =====
+Specialization of Communication Endpoint, Node Role, Data Structure Instance, and Runtime Plane from Part 1, Sections 7.6, 7.4, 7.8, and 7.5; generalised from domain-event and data-plane publication material in the original FX Demo Reference Architecture.
+===== Note =====
+An Event Producer Role does not require event-streaming technology. Implementation profiles realize events through the selected communication mechanism.
+===== Example =====
+A logical Transaction Intake Node serves as an Event Producer Role when it publishes a transaction-received event.
