Editorial Changelog
What changed, and when
Every page on this site is dated. When a number changes we keep the previous value and the date it changed, so the history is visible rather than silently overwritten.
The full dated record is being built. Until then, every page carries its own verified date in the masthead, and the data points underneath link to the original source. You can already see when a state's facts were last checked on that state's page; this index will roll them together.
How we keep this current
Every fact has a re-check date. Most are on a roughly 90-day cycle; fast-moving items (rate filings, FAIR Plan caps, carrier exits) get checked more often. An automated sweep flags facts that have come due, and a person re-verifies them against the original source before the date on the page changes. When a value actually changes, the previous value and the change date are kept. That is the "we caught it" signal this changelog will surface.
In the meantime: see how we compile and verify for the full method, and /states/ for every state with its current verified-through date.
