====== 11.1 Overview ====== [[fxdemo:04-part:11-phase-0-runtime-plane-realization:start | Go To Phase 0 Runtime Plane Realization ]] This section defines how the Phase 0 Implementation Profile realizes the FX Runtime Plane distinctions defined in the Part 3 FX Demo Logical Profile. A [[dido:99_annexes:annex-b-terms-and-definitions:r:runtime_plane|Runtime Plane]] classifies interactions by architectural purpose. Phase 0 realizes those distinctions through DDS Topic naming, QoS profile selection, implementation Node responsibilities, logging categories, exception-handling behavior, traceability metadata, and repository organization. Runtime Plane realization does not redefine the FX Runtime Planes. The FX Demo Logical Profile remains the authoritative source for the meaning of Runtime Plane. Part 4 defines how Phase 0 implementation artifacts preserve and express those distinctions. ---- © 2026 Dido Solutions, Inc. and Jackrabbit Consulting, Inc.
