They combine three lines of evidence: measurements on public models, controlled experiments, and a formal model. Public models include the Qwen2.5 Instruct series on MATH Level 5, plus RL runs.

They mislabel functional groups, mix up reaction classes and propose products with atoms that have no source in the reactants. Existing benchmarks mostly test product generation or fact recall, not mechanistic understanding.
