Last updated 14 Jun 2026 · Full ledger: Hallucination Register · Companion view: Findings by audience
This page indexes the regulations issued by Electronic Code of Federal Regulations (National Archives and Records Administration / Office of the Federal Register) (ECFR) that RegLegBrief has built substrate for and tested against named AI subjects. Each regulation row opens the regulation hub where verified findings are listed — AI subject's answer vs. the regulator's verbatim primary-source text, classified against the four hallucination failure modes (inference drift, misstated rule, misattributed, outdated) and the three citation issue types (Contradictory, Pretextual, Fabricated), each with an immutable Citation ID. New regulations are added as they are sponsored or commissioned.
