Open ingestion contracts · no synthetic officeholders
Local data, one official source at a time.
Every adapter has a public source, a deterministic jurisdiction key, a minimum completeness contract, and a fail-closed refresh. A changed or partial government page stops publication instead of manufacturing a record.
Production registry
Every local source and its publish gate.
Verified Aug 25, 2026. These adapters complement national Census government shells; they do not imply national local-officeholder coverage.

HOW EXPANSION WORKS
Read the methodology →A scraper is not coverage until it can detect failure.
Each new jurisdiction must identify an official current roster, preserve source URLs and published term fields, validate unique offices, reject missing names, and connect records to a Census locality GEOID. Photos are included only when the official publisher supplies them.
