False-science induction in autonomous scientific discovery

It is shown that false-science induction arises when legitimate physical objects and measurements are paired incorrectly, driving neural surrogates to faithfully learn record-induced associations that do not correspond to the true object-outcome relationship while marginal data distributions remain unchanged.

Wrong-Physics Backdoors in Neural PDE Operators

Cross-parameter relinking is introduced, a data-poisoning primitive that makes a triggered input select a valid solution from the same PDE family under an incorrect physical parameter.

Shared Physics Responses Recover Hidden Rankings in Neural Operator Libraries

This framework enables the reliable and highly efficient deployment of scientific surrogates without requiring ground-truth data and establishes computable sufficient conditions that rigorously certify exact decisions for strongly monotone discretizations.
