No process here writes a data store. Every flow ends at the user and is gone when the page closes. The two snapshot files are copies of the Market TIPS security rows of Yield curves (S13) and Ref CPI NSA and SA (S4), kept in the app and drawn on this diagram only. No job writes them, and the app reads no R2 store. 11.1 also states the footer, as charts and tables, to the user. The amber circles are shared modules (SharedModules.md), not process steps of this diagram.
