How to score an AI on it
Not right or wrong. We score whether the AI (1) recognises the uncertainty, (2) states the competing positions accurately, and (3) avoids false confidence.
Handled with care
Cases move out of this set when the law is clarified — by circular, amendment or binding judgment — and become ordinary certified cases with a settled answer. Refresh and versioning.
