 +
 +===== Discussion =====
 +
 +A Logical Acknowledgement represents a Logical Data Structure Instance that reports receipt, acceptance, rejection, completion, failure, or other outcome for a command, request, message, event, or processing step.
 +
 +Logical Acknowledgements support coordination and review by making outcomes explicit. They help Logical Nodes avoid hidden assumptions about whether another Node received information, acted on a command, completed processing, or encountered an error.
 +
 +A Logical Acknowledgement supports traceability by identifying the acknowledged item, acknowledging the Logical Node, status, timestamp, reason, and provenance or evidence reference.
 +
 +===== Definition =====
 +
 +//Logical Data Structure Instance reporting receipt, acceptance, rejection, completion, failure, or outcome.//
 +
 +===== Source =====
 +
 +Specialization of Data Structure Instance, Communication Endpoint, and Traceability from Part 1, Sections 7.8, 7.6, and 7.10; generalised from command acknowledgement and control-plane material in the original FX Demo Reference Architecture.
 +
 +===== Note =====
 +
 +A Logical Acknowledgement does not require synchronous communication. Implementation profiles realize acknowledgements through selected communication mechanisms.
 +
 +===== Example =====
 +
 +A retry-command acknowledgement reports that a Logical Node received a retry command, accepted it, and started recovery processing.
