Table 8-1: Navigation guide for selecting the appropriate document part

Question	Read
What are the durable financial system concepts?	Part 1: Conceptual Architecture
What is the platform-independent logical model?	Part 2: Logical Architecture / PIM
How does the model apply to Foreign Exchange?	Part 3: FX Demo Logical Profile
How does Phase 0 map the logical model to DDS, IDL, Python, and container images?	Part 4: Phase 0 Implementation Profile / PSM
How does Phase 0 run, deploy, test, and collect evidence?	Part 5: Phase 0 Deployment, Testability, and Evidence Plan

A reader should not begin with Part 5 to understand the architecture. Part 5 explains how one implementation runs. It does not define the conceptual or logical architecture. A developer working on Phase 0 may spend most of their time in Parts 4 and 5. An architect reviewing the separation of concerns should begin with Parts 1 and 2. A domain reviewer focused on FX should begin with Part 3. A reviewer assessing evidence should use Part 5 while tracing claims back through Parts 4, 3, 2, and 1.
