+What's in the data
+A row appears when an employer meets ALL of these criteria:
+
+- The employer is a federal contract recipient on USAspending.gov (any prime contract obligation, any fiscal year).
+- The employer is in FastDOL's structured records (resolvable via name normalization + state + ZIP, the platform's standard entity-resolution key).
+- The employer has **at least one violation category met** across the eight enforcement surfaces FastDOL tracks: OSHA (workplace safety), WHD (wage and hour), MSHA (mine safety), EPA (environmental), NLRB (labor relations), SEC (financial enforcement), UVA Corporate Prosecution Registry (federal criminal/civil prosecutions), and SAM.gov exclusions (federal debarment).
+
+The `violation_categories_met` column reports the count (1–8) of those surfaces the employer hits, with per-agency totals broken out across the other columns. Each row is one employer, with total federal contract obligations, contract award count, top awarding agency, and per-agency enforcement counts and dollar penalties. The dataset is designed to surface the federal contractors that continue to receive taxpayer dollars despite documented enforcement records against them.
