What was already known
The Jacobian conjecture predicts global polynomial invertibility from a nonzero constant Jacobian.
What changed and why it matters
Advances the stated target relative to the recorded baseline.
The AI contribution
The original writeup credits Alpöge’s announced example and Fable, with a human posing the question and humans analyzing its geometry.
Limitations
The two-variable case remains separate. Public provenance and disclosure questions raised by Vasiu are unresolved; sole AI priority is not claimed. AIProofWatch has not audited the full argument or formal proof.
Verification evidence
Evidence labels show what supports the claim. Importance rates its impact if correct.
Author claim
The original source reports this scoped result; AIProofWatch reviewed its statement, not the full proof.
Accessible artifact / proof
A research manuscript or proof artifact is publicly accessible; availability is not independent checking.
