===== Discussion =====

FX Endpoint Traceability relates an FX logical [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_communication_endpoint|Communication Endpoint]] to its inherited logical source, conceptual source, participating FX logical [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_node|Nodes]], Communication Roles, FX information structures, [[dido:99_annexes:annex-b-terms-and-definitions:r:runtime_plane|Runtime Plane]] classification, governance constraints, and [[dido:99_annexes:annex-b-terms-and-definitions:e:evidence|Evidence]] expectations.

FX Endpoint Traceability supports reviewing the movement of FX information. It identifies which FX logical [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_node|Nodes]] produce information, which [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_node|Nodes]] consume information, which information structures the endpoint carries, which [[dido:99_annexes:annex-b-terms-and-definitions:r:runtime_plane|Runtime Plane]] frames the exchange, and which policy, governance, audit, provenance, or [[dido:99_annexes:annex-b-terms-and-definitions:e:evidence|Evidence]] expectations apply.

FX Endpoint Traceability also protects the distinction between FX logical [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_communication_endpoint|Communication Endpoints]] and implementation mechanisms. Part 4 maps FX logical [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_communication_endpoint|Communication Endpoints]] to selected implementation artifacts, but the FX logical endpoint remains the architectural relationship to trace.

===== Definition =====

//Traceability relationship connecting an FX logical Communication Endpoint to inherited logical sources, conceptual sources, participating Nodes, Communication Roles, information structures, Runtime Plane classifications, governance constraints, and evidence expectations.//

===== Source =====

Specialization of [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_endpoint_traceability|Logical Endpoint Traceability]] from Part 2, Section 12.4, [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_communication_endpoint|Logical Communication Endpoint]] from Part 2, Section 7.2, [[dido:99_annexes:annex-b-terms-and-definitions:c:communication_endpoint|Communication Endpoint]] from Part 1, Section 7.6, and [[dido:99_annexes:annex-b-terms-and-definitions:t:traceability|Traceability]] from Part 1, Section 7.10; generalised from FX endpoint, topic, and interaction traceability material in the original FX Demo Reference Architecture.

===== Note =====

FX Endpoint Traceability does not imply a [[dido:99_annexes:annex-b-terms-and-definitions:d:dds|DDS]] Topic, [[dido:99_annexes:annex-b-terms-and-definitions:r:rest|REST]] resource, [[dido:99_annexes:annex-b-terms-and-definitions:r:rpc|RPC]] method, message queue, event stream, file, database table, or network route.

===== Example =====

The [[dido:99_annexes:annex-b-terms-and-definitions:f:fx_cash-flow_obligation_endpoint|FX Cash-Flow Obligation Endpoint]] traces to the [[dido:99_annexes:annex-b-terms-and-definitions:f:fx_cash-flow_computation_node|FX Cash-Flow Computation Node]], [[dido:99_annexes:annex-b-terms-and-definitions:f:fx_policy_and_release_node|FX Policy and Release Node]], [[dido:99_annexes:annex-b-terms-and-definitions:f:fx_audit_and_provenance_node|FX Audit and Provenance Node]], the [[dido:99_annexes:annex-b-terms-and-definitions:f:fx_cash-flow_obligation|FX Cash-Flow Obligation]] information structure, the [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_data_plane|Logical Data Plane]], and the [[dido:99_annexes:annex-b-terms-and-definitions:e:evidence|Evidence]] expectations for computation review.
