No process here writes a data store. Every flow ends at the user and is gone when the page closes, except the files the Export menu writes. 4.1 reads Market quotes (S7), the live default; FedInvest prices (S1) is the same module's dormant fallback and is not drawn. The Explore price files are kept in the app and drawn on this diagram only: no job writes them. Explore builds with the interface and the output of Build, so 4.6 feeds 4.3. Build and Rebalance are separate processes with separate interfaces; the code they share is in the shared modules. The amber circles are shared modules (SharedModules.md), not process steps of this diagram.
