====== 6.2 Part 3 Working Baseline ====== [[fxdemo:04-part:06-phase-0-implementation-preconditions:start | Go To Phase 0 Implementation Preconditions ]] The Part 3 FX Demo Logical Profile must be in place as a working baseline before Phase 0 implementation begins. The working baseline identifies the FX logical [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_node|Nodes]], logical [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_node_role|Node Roles]], logical [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_communication_endpoint|Communication Endpoints]], logical information structures, [[dido:99_annexes:annex-b-terms-and-definitions:r:runtime_plane|Runtime Planes]], interaction patterns, governance relationships, [[dido:99_annexes:annex-b-terms-and-definitions:t:traceability|traceability]] relationships, and logical requirements that Part 4 maps to implementation artifacts. Phase 0 implementation work must preserve traceability to that baseline. A Phase 0 implementation artifact must identify the FX logical element, implementation concern, or supporting function it realizes or supports. A later change to the Part 3 working baseline may require review of affected Phase 0 implementation mappings, [[dido:99_annexes:annex-b-terms-and-definitions:i:idl|IDL]] structures, [[dido:99_annexes:annex-b-terms-and-definitions:d:dds|DDS]] Topic mappings, generated types, Quality of Service (QoS) profiles, repository artifacts, scripts, and Developer Handbook rules. ---- © 2026 Dido Solutions, Inc. and Jackrabbit Consulting, Inc.
