The Supervisory Priorities Index measures how much of each agency's written record — annual reports, examination handbooks, supervisory guidance — was devoted to each risk domain in each year. Pick an agency and a domain; the chart updates locally. No server is doing the work. The full panel ships to your browser as a 234 KB parquet file and is queried with DuckDB compiled to WebAssembly.

The view above is intentionally minimal: one agency, one domain, one chart. The cross-agency comparator and the structural-breaks finder live on separate pages, and the Reader Assessment page lets you query the panel by year, event, or named actor.
What you are looking at. The y-axis is the share of each
year's written record (across that agency's annual reports and supervisory
guidance) that was devoted to the selected domain. Spikes are not noise.
They are the moments at which the agency, in its own words, decided that
the domain mattered enough to write about it. Decay is real, too. The
cycle the book documents — rise, peak, decline, displacement —
is visible in almost every domain at some point in the panel.
