====== 12.1 Overview ====== [[fxdemo:04-part:12-phase-0-interaction-pattern-realization:start | Go To Phase 0 Interaction Pattern Realization ]] This section defines how the Phase 0 Implementation Profile realizes selected FX logical interaction patterns from the Part 3 FX Demo Logical Profile. An FX logical interaction pattern defines platform-independent behavior among FX logical Nodes, Node Roles, Communication Endpoints, information structures, Runtime Planes, governance constraints, traceability relationships, and evidence expectations. A Phase 0 interaction realization maps that logical behavior to selected implementation participants, DDS Topics, IDL structures, generated types, scripts, logging conventions, exception-handling conventions, and traceability records. The implementation realization does not redefine the logical interaction pattern. It identifies how Phase 0 implements selected behavior while preserving traceability to the Part 3 logical pattern. ---- © 2026 Dido Solutions, Inc. and Jackrabbit Consulting, Inc.
