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.

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.
Adjacent regulatory universe
Rulemakings, enforcement actions, audits, fiscal notes, permits, benefit programs, infrastructure approvals, and regulated-entity filings all leave structured records. Justinian keeps those records next to the authority they depend on.

Source-by-source index
All 141 corpus types across 15 categories. Each entry links to its source family, jurisdictional scope, document and data types, and volume notes where the audit provides them.
Primary law and the procedural fabric around it — statutes, regulations, registers, guidance, acts, bills, court rules, and citation-linked authority.
Where most law actually touches people — every municipal code and local ordinance in America.
The money trail: budgets, appropriations, expenditures, awards, payroll, fiscal notes, audits, public finance, and program funding records.
CMS, Medicaid, Medicare, provider, claims, coverage, quality, and public-health datasets tied back to the rules that govern them.
Environmental permits, enforcement, monitoring, water systems, emissions, facilities, and agency operational records.
Energy transactions, grid records, utilities, infrastructure approvals, EIA statistics, FERC surfaces, and oil-and-gas operational data.
Labor observations, benefits filings, workforce notices, employment datasets, agency cases, and enforcement records.
K-12 and higher-education agencies, metrics, reports, funding, accountability, and federal education data.
Policing, FBI UCR, ATF, traffic safety, courts-adjacent public safety records, and enforcement datasets.
FMCSA, NHTSA, BTS, FHWA, FRA, FAA, FTA, state DOT, bridges, carriers, crashes, transit, aviation, and traffic records.
USDA, SNAP, FSA payment, NRCS, agriculture facts, geospatial layers, and food-assistance operational data.
Transparency filings — what regulated entities and public officials are required to put on the record.
Secondary sources, government reports, census surfaces, policy literature, public datasets, and context for questions primary law has not answered yet.
Louisiana-specific legal, environmental, finance, elections, health, disaster, labor, land, natural resources, and public-record source systems.
Louisiana oil, gas, and conservation records (SONRIS).
