Reader and dashboard as one system
The book, sector readers, graph pages, and the scenario room are different interfaces over the same evidence environment. The user should be able to move from prose to data and back without losing context.
Drawers, panels, and control surfaces
Source drawers, method drawers, caveat panels, and mobile control sheets are implementation details with analytical consequences. They decide whether a user can actually inspect evidence instead of trusting a black box.
Expert path and public release discipline
Expert feedback, sandbox states, and public evidence must remain distinct. Implementation has to preserve that distinction through route logic, labels, payload design, and privacy-aware submission flows.
