The Corpus

Every federal regulation. Every state statute. Every municipal code in America. 13.125 billion court records, and every bill across all fifty state legislative sessions and the federal session.

Beside the law sits the record it produced: public finance, health, environment, labor, energy, education, transportation, agriculture, disclosures, and state operational data.

Corpus manifest

This is the distinction that matters: the law, the record that produced it, the courts that interpret it, and the agency data that shows how it works in practice live in one linked corpus.

A great gilded basilica with domes and minarets, the corpus rendered as imperial architecture

Primary sources only. Continuously refreshed.

The corpus is built source by source: agency portals, court systems, state registers, municipal codes, fiscal warehouses, environmental systems, health datasets, labor observations, education metrics, energy records, transportation records, disclosures, and state-specific operational systems.
