Researchers have developed a method to detect silent mismatches in robot actions, where actions satisfy basic constraints but lack correct semantics. This approach uses learned state-action-effect relations as offline contracts to identify and rank potential issues like permuted axes or inverted signs. Experiments on LIBERO Spatial tasks showed that a calibrated relational world model achieved 65.7% recall in detecting these mismatches, outperforming simpler methods and demonstrating a trade-off between detection and localization accuracy.
