    "body_text": "Real movement rules often prioritize some duties without ranking every possible conflict. This framework derives scenario-specific agent preferences from partially ordered legal guidelines, then lets agents add private objectives without creating new illegal equilibria. Belief play coordinates without revealing those private preferences. In seven maritime encounters with up to four vessels, every violation in the committed equilibria was certified as forced by the hierarchy or unsatisfiable, and tested defectors were identified from public information. The cases are limited and do not constitute legal certification, but the method makes the path from written guidance to a motion plan inspectable.",
