===== Statement =====

An Implementation Profile / PSM SHALL preserve the FX Demo Logical Profile defined in this part.

===== Source =====

Part 3, Section 17.12: Implementation Boundary Requirements.

===== Rationale =====

An Implementation Profile or Platform-Specific Model realizes the logical architecture rather than replacing or modifying it. Preserving the FX Demo Logical Profile ensures that all implementation decisions remain faithful to the platform-independent architecture while allowing implementation-specific technologies, deployment strategies, and runtime mechanisms to vary.

This preservation maintains architectural consistency, interoperability, governance, and conformance across different implementations.

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

This requirement applies to every Implementation Profile and Platform-Specific Model derived from the FX Demo Logical Profile.

It applies specifically to:

  * Implementation Profiles;
  * Platform-Specific Models;
  * implementation architecture;
  * conformance assessment; and
  * implementation governance.

===== Verification =====

Verification SHALL confirm that each Implementation Profile or Platform-Specific Model preserves the FX Demo Logical Profile.

Verification activities should include review checks confirming that:

  * logical architectural meaning is preserved;
  * implementation-specific realizations remain consistent with the logical profile;
  * architectural relationships remain intact; and
  * implementation choices do not modify the logical architecture.

===== Traceability =====

This requirement establishes preservation of the FX Demo Logical Profile within derived implementations.
