The CSV is the reusable table. The dictionary defines each field. The change feed reports verified source snapshots without creating artificial updates when nothing changed.
Definitions follow the controlling state table. Display pages may expand locality abbreviations for navigation, but the downloadable CSV preserves the agency label.
