===== Statement =====

The Phase 0 Implementation Profile / PSM SHALL preserve traceability to the Part 1 Conceptual Architecture, the Part 2 Distributed Node-Based Logical Architecture / PIM, and the Part 3 FX Demo Logical Profile.

===== Source =====

Part 4, Section 21.2: Phase 0 Profile Requirements.

===== Rationale =====

Phase 0 is part of a layered architectural progression. Preserving traceability to Parts 1, 2, and 3 ensures that implementation decisions remain connected to their conceptual, logical, and FX-specific logical sources.

This traceability allows reviewers to determine how Phase 0 implementation choices derive from and remain consistent with the preceding architectural layers.

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

This requirement applies to:

  * Phase 0 implementation mappings;
  * implementation artefacts;
  * implementation traceability records;
  * implementation governance; and
  * architectural review of the Phase 0 baseline.

===== Verification =====

Verification SHALL confirm that the Phase 0 Implementation Profile / PSM preserves traceability through Parts 1, 2, and 3.

Verification activities should include review checks confirming that:

  * Phase 0 implementation artefacts trace to applicable Part 3 elements;
  * applicable Part 3 elements retain their Part 2 logical traceability;
  * applicable Part 2 elements retain their Part 1 conceptual traceability; and
  * implementation mappings do not break the established architectural traceability chain.

===== Traceability =====

This requirement preserves the architectural traceability chain from conceptual architecture through logical architecture and the FX Demo Logical Profile to Phase 0 implementation.
