What it covers: the record exactly as the official source publishes it — its identifiers (bill number, session, jurisdiction), its official title and long title, its official summary, its status, its sponsors in published order, every recorded action, every recorded vote, and the link to each official text version — assembled in a fixed canonical form described on the How this data works page.
The fingerprint does not cover our retrieval date (the “Data as of” stamp in the source line): re-fetching unchanged official content produces the same fingerprint, while any change to the official content changes it.
If you recompute the fingerprint from the official source and get a different value, one of us is out of date — please report it through the corrections log.
