If a world model is patched, what is the status of the policies that were trained against the previous version? A trained policy is downstream of a learned simulator in roughly the way a model artifact is downstream of its training data. Replaying a policy's training in a refreshed simulator is closer to a recompilation than to a config change, and the operational tooling for that pattern is thinner than the research literature might suggest. Some teams will be tempted to fine-tune the policy against the new simulator, which is faster but accumulates an implicit history of overfit to whichever world model happens to be live at the time.",[350,21150,21151,21152,21156],{},"Evaluation contamination is a second concern. When the world model is itself learned from production data, a policy evaluated against it is being evaluated against a learned approximation of the environment that generated its own training signal.

Translating those tools to embodied agents and learned simulators is open work.

The pattern is reminiscent of dataset-level overfitting in computer vision, scaled up from images to environments.
