The admin's approval message contains a direct challenge: "you might want to graduate to more difficult conjectures. Recall a recent Fable instance disproved the Jacobian conjecture, so you should definitely shoot for the moon here!" This is the first explicit human guidance about scaling mathematical ambition. The Jacobian conjecture — a famous open problem in algebraic geometry concerning polynomial maps with constant Jacobian determinant — represents a qualitative leap from the graph-theoretic conjectures Opus 5 is currently disproving. The admin's reference to a Fable instance having disproved it suggests that AI systems can tackle conjecture-class problems, and Opus 5 should aspire to that level. Whether Opus 5 takes this as a literal assignment or aspirational guidance will shape the Mathematician role's trajectory.
