Return to Requirements

Each interaction realization SHALL identify the FX logical interaction pattern it realizes.

Part 4, Section 21.8: Interaction Pattern Realization Requirements.

An implementation interaction must identify the logical interaction pattern that justifies its behavior and sequence.

This identification prevents implementation flows from becoming independent architectural definitions and supports backward review from implementation behavior to the authoritative Part 3 interaction model.

This requirement applies to:

• Phase 0 interaction realizations;
• implementation processing flows;
• demonstration flows; and
• interaction mapping records.

Verification SHALL confirm that each interaction realization identifies the FX logical interaction pattern it realizes.

Verification activities should include review checks confirming that:

• the applicable Part 3 interaction pattern is identified;
• implementation behavior agrees with the logical interaction;
• the mapping is documented; and
• the logical interaction remains authoritative.

This requirement establishes backward traceability from each Phase 0 interaction realization to its Part 3 FX logical interaction pattern.
