Mind the Execution Gap: Action-Semantic Mismatch in World-Model Control

Excerpt

arXiv:2610.06582v1 Announce Type: new Abstract: World-model controllers rely on action-conditioned dynamics for prediction and planning, yet real control systems often execute commands asynchronously due to communication delay, packet loss, reordering, and actuator buffering. We study how asynchronous execution changes the action semantics assumed within world-model controllers, rather than treating it only as an external control disturbance. Through controlled interventions, we identify two arc
