===== Statement =====

Implementation traceability SHALL support forward review from FX logical elements to Phase 0 implementation artifacts.

===== Source =====

Part 4, Section 21.14: Implementation Traceability Requirements.

===== Rationale =====

Forward traceability allows reviewers to begin with an FX logical element and determine how that element is realized within the Phase 0 implementation baseline.

This supports completeness review by making it possible to identify the implementation artifacts, mappings, configuration, and supporting concerns associated with selected FX logical elements.

===== Applies To =====

This requirement applies to:

  * FX logical Nodes and Node Roles;
  * Communication Endpoints;
  * information structures;
  * Runtime Planes;
  * interaction patterns; and
  * their Phase 0 implementation realizations.

===== Verification =====

Verification SHALL confirm that forward review from FX logical elements to Phase 0 implementation artifacts is supported.

Verification activities should include review checks confirming that:

  * selected FX logical elements have identifiable implementation mappings;
  * mapped implementation artifacts can be located;
  * relevant supporting artifacts can be identified; and
  * missing implementation mappings can be detected.

===== Traceability =====

This requirement establishes forward traceability from the Part 3 FX Demo Logical Profile into the Part 4 implementation baseline.
