Do Tabular Foundation Models Know Physics? Contamination, Units, and the Deterministic Limit

Tabular models memorize physics patterns but don't learn physics as a causal structure. This matters if you're using TFMs for scientific or engineering applications where you need to extrapolate rather than interpolate. They're good interpolators, weak at structural reasoning. For builders: they're not yet replacements for domain-specific solvers, but they're useful as feature extractors in hybrid systems.
