Jetsam
Know what makes it through airport security before you pack. A ruling with cited sources, resolved across airline, airport, regulator and date.
The problem
The sources conflict by design. Four layers of authority publish rules about the same object, and the correct answer changes with the date you fly. Single-pass retrieval answers "yes" when the truth is "yes, but".
What I did
Adversarial retrieval that looks for the rule that would overturn the first answer, documents indexed with their effective dates, and precedence between authorities resolved in code instead of left to the model.
What changed
The same question returns different, correct rulings for different travel dates, with the governing rule highlighted in its source.
