ExecutionBridge: Plans Are Not Executions
A research prototype adapts a world model’s imagined future to match how deployment controllers actually execute the same plan.
Field notes
The workflow uses planned-executed trajectory pairs to identify persistent controller behavior, caches that representation, and applies a bounded latent correction before candidate scoring. The page reports a controller-disjoint evaluation across ten held-out configurations, with low-score PDMS moving from 32.038 to 46.128. A direct-substitution comparison produces only a +0.048 full-set gain, separating the proposed adaptation from simply replacing the planned trajectory.
