 +====== Logical Compatibility ======

 +
 +===== Discussion =====
 +
 +Logical Compatibility identifies whether two or more logical elements work together without loss of meaning, structure, traceability, governance, or evidence expectations.
 +
 +Logical Compatibility applies to Logical Nodes, Logical Communication Endpoints, Logical Data Structure Definitions, Logical Data Structure Instances, Logical Runtime Planes, Logical Interaction Patterns, and Logical Policy Constraints.
 +
 +Logical Compatibility supports distributed operation. A producing Logical Node and a consuming Logical Node require compatible expectations about endpoint purpose, information structure, semantic meaning, version context, interaction pattern, and Runtime Plane participation.
 +
 +Logical Compatibility does not require identical implementation technologies. Two implementation profiles use different technologies while preserving logical compatibility by maintaining the same logical definitions, interaction expectations, traceability, and governance constraints.
 +
 +===== Definition =====
 +
 +//Condition in which logical elements work together without loss of meaning, structure, traceability, governance, or evidence expectations.//
 +
 +===== Source =====
 +
 +Specialization of Traceability, Governance and Authority, Data Structure Definition, and Communication Endpoint from Part 1, Sections 7.10, 9.6, 7.7, and 7.6; generalised from compatibility and versioning concerns in the original FX Demo Reference Architecture.
 +
 +===== Note =====
 +
 +Logical Compatibility concerns the meaning and behavior of logical elements. It does not imply binary compatibility, protocol compatibility, wire-format compatibility, or deployment compatibility.
 +
 +===== Example =====
 +
 +A Logical Node that publishes a validation-result event and a Logical Node that consumes that event remain logically compatible when both use the same logical endpoint purpose, information definition, version context, and Runtime Plane classification.
