Corpus proof

Corpus scale

A governed historical corpus enabling temporal reconstruction, authority tracing, and citation lineage across customs rulings.

220,445 Rulings

172 HTS editions

23,953 CFR sections

698,614 Authority edges

1,006,874 Corpus objects

What this enables

Temporal reconstruction — bind holdings to HTS editions at ruling date
Authority tracing — ruling-to-ruling and HTS lineage edges
Historical HTS binding — compare issuance tariff against current corpus
Contradiction detection — surface modifying rulings and supersession
Citation lineage — seven-stage provenance from query to LegalSnapshot
