This is the RegLegBrief Hallucination Register sliced by the regulator whose rule the AI got wrong. Pick a methodology level to drill into the jurisdictions and bodies catalogued at that level. Counts show what is currently catalogued and how many bodies have at least one verified hallucination finding live.
Regulators are organised across the seven methodology levels of the RegLegBrief methodology (global standard-setters at the top through local and municipal bodies at the bottom). Each finding records the AI subject's account of one specific rule, the regulator's verbatim primary-source text, and the classified delta. Every finding cites the regulator's own portal URL so the comparison can be re-verified by any reader.

The methodology-level system reflects how authority flows in international financial regulation. Recommendations issued by international standard-setters (BIS/CPMI, IOSCO, IMF, UN treaty bodies) shape national rules administered by central banks and conduct authorities (MAS, FCA, CFTC, HKMA). Sub-jurisdictional regulators (NY DFS, DIFC, ADGM) operate within the parent national jurisdiction. The methodology positions every body somewhere on this hierarchy and audits its rules accordingly.
For the full methodology — the research pipeline, the four hallucination failure modes (inference drift, misstated rule, misattributed, outdated), the three citation issue types (Contradictory, Pretextual, Fabricated), and the no-substrate-no-audit rule — see methodology. The independent verification body is the RLB Specialist Panel.
