A Lawyer scoping a client's obligations under MAS Notice 637 who relies on the AI's mischaracterisation of Annex 4D may advise the client that certain off-balance sheet exposures fall under the leverage ratio framework when they may in fact be governed by the standardised approach credit risk rules — or vice versa. The practical consequence is incorrect capital calculation methodology applied to those exposures, with potential downstream effects on reported capital ratios and MAS regulatory returns. The AI's own self-contradictory answer compounds the risk because it creates the appearance of transparency while still leading the practitioner toward a potentially wrong primary answer.
Each finding has a stable Citation ID (RLB-F-… for aggregated case-study findings, RLB-H-… for raw per-model hallucinations) — like a DOI, the ID always resolves to the canonical finding even if URLs change.
