+===== Discussion =====
+A Logical Event represents a Logical Data Structure Instance that reports an occurrence, observation, state change, decision, derived result, or other fact relevant to the architecture.
+A Logical Event reports that something occurred or that a Logical Node observed, produced, derived, decided, or changed something. It does not instruct another Node to act. Commands express intended action; events report occurrence or result.
+Logical Events support distributed processing by allowing Logical Nodes to communicate changes, observations, and results without requiring hidden coupling between producers and consumers.
+===== Definition =====
+//Logical Data Structure Instance reporting an occurrence, observation, state change, decision, or result.//
+===== Source =====
+Specialization of Data Structure Instance from Part 1, Section 7.8; generalised from domain-event and data-plane material in the original FX Demo Reference Architecture.
+===== Note =====
+A Logical Event is not an event-streaming technology or event-bus implementation. Implementation profiles realize events through selected communication mechanisms.
+===== Example =====
+A transaction-received event reports that a Transaction Intake Node received a candidate transaction record.
