===== Statement =====

The FX Demo Logical Profile SHALL define the following FX logical Node Roles:

  * Transaction Intake Role
  * Structural Validation Role
  * Semantic Interpretation Role
  * Contract State Management Role
  * Cash-Flow Computation Role
  * Policy Evaluation Role
  * Release Control Role
  * Audit Recording Role
  * Provenance Recording Role
  * Health Reporting Role
  * Registry and Coordination Role
  * Replay and Reconstruction Role
  * Oversight Consumption Role

===== Source =====

Part 3, Section 17.4: FX Logical Node Role Requirements.

===== Rationale =====

The identified FX logical Node Roles provide the standard architectural responsibilities required to model the Foreign Exchange Domain. Defining a common set of logical Node Roles promotes architectural consistency, interoperability, governance, and traceability while allowing multiple implementations to realize the same logical responsibilities using different technologies.

===== 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 Role definitions;
  * logical architectural reviews;
  * Domain Logical Profiles; and
  * derived Implementation Profiles.

===== Verification =====

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

Verification activities should include review checks confirming that:

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

===== Traceability =====

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