Verification in Legal AI Is a Design Problem
Lawyers remain responsible. Legal AI should make its work easy to check before they sign.
The factual record for litigation.
Nothing gets past Mary.

Issues requiring review7 open
Different accounts of approvalContradiction
Board minutes say approval was given on March 11. The CFO's March 14 email says approval remained conditional.
Referenced attachment not locatedMissing
Email dated April 7 refers to “final schedule.xlsx.” No matching attachment appears in the production.
No records for 84 daysUnresolved
No produced material covers June 8 through August 31 for this issue. The record keeps the period visible for review.
Confidence you can check
Trust it because you can check it.
Every entry shows whether it's supported, contradicted, or still unconfirmed, and you can open any one and check it for yourself. You don't have to take the record on faith.

What it means
What “nothing gets past Mary” means in practice.
Mary does not decide the case. Mary shows the whole record, including what's missing and what doesn't add up, so the lawyer can.
Every document accounted for
Coverage stays visible across the whole matter.
Contradictions stay visible
Competing accounts are not collapsed into one answer.
Gaps remain explicit
Missing and unresolved material stays in the record.
Every claim shows its confidence
Supported, contradicted, or unconfirmed, never hidden.
Changes stay under human review
Proposed updates remain pending until someone approves them.
Mary shows the record. You make the judgment.
Legal judgment remains with the lawyer.
