===== Statement =====

Each FX logical information structure SHALL preserve traceability to Data Structure Definition, Data Structure Instance, Evidence, Traceability, or other applicable Part 1 concepts.

===== Source =====

Part 3, Section 17.6: FX Logical Information Requirements.

===== Rationale =====

Preserving traceability to the applicable Part 1 concepts ensures that every FX logical information structure maintains a direct relationship to the conceptual architectural elements from which it is derived. This supports architectural governance, impact analysis, conformance assessment, evidence generation, and long-term maintainability while preserving consistency across the layered architecture.

Maintaining conceptual traceability enables reviewers to understand how domain-specific logical information structures evolve from the conceptual information model established by the Reference Architecture.

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

This requirement applies to every FX logical information structure defined by the FX Demo Logical Profile.

It applies specifically to:

  * information structure traceability;
  * architectural governance;
  * logical information architecture reviews;
  * conformance assessments; and
  * architectural maintenance.

===== Verification =====

Verification SHALL confirm that each FX logical information structure preserves traceability to the applicable Part 1 architectural concepts.

Verification activities should include review checks confirming that:

  * traceability relationships are documented;
  * originating Part 1 concepts are identified;
  * traceability remains complete throughout the profile; and
  * traceability is maintained during architectural evolution.

===== Traceability =====

This requirement supports end-to-end architectural traceability from the Part 1 Conceptual Architecture through the Part 2 Logical Architecture to the FX Demo Logical Profile.
