===== Statement =====

The FX Demo Logical Profile SHALL define the following FX logical Nodes:

  * FX Transaction Intake Node
  * FX Validation Node
  * FX Semantic Interpretation Node
  * FX Contract State Node
  * FX Cash-Flow Computation Node
  * FX Policy and Release Node
  * FX Audit and Provenance Node
  * FX Health and Observability Node
  * FX Registry and Coordination Node
  * FX Replay and Reconstruction Node
  * External Oversight Participant

===== Source =====

Part 3, Section 17.3: FX Logical Node Requirements.

===== Rationale =====

The identified logical Nodes collectively define the logical responsibilities required to model the Foreign Exchange Domain. Establishing a standard set of logical Nodes promotes consistency across implementations while providing a common architectural vocabulary for governance, interoperability, and traceability.

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

This requirement applies to the definition, review, maintenance, and evolution of the FX Demo Logical Profile.

It applies specifically to:

  * FX logical Node definitions;
  * logical architectural reviews;
  * Domain Logical Profiles; and
  * derived Implementation Profiles.

===== Verification =====

Verification SHALL confirm that every required FX logical Node is defined.

Verification activities should include review checks confirming that:

  * each required logical Node is present;
  * logical Node names are consistent with the architectural specification;
  * no required logical Node is omitted; and
  * each logical Node is uniquely identifiable.

===== Traceability =====

This requirement establishes the required logical Node inventory for the FX Demo Logical Profile.
