World-Coherent Decoding (WCD) is a test-time planning framework for World Action Models (WAMs) that treats rollouts as falsifiable future–action hypotheses. At each decision step, WCD samples multiple candidates from a frozen WAM and ranks them using flow-based video surprisal for visual plausibility and action path effort for generation stability. After execution, the observed outcome audits the chosen imagination, producing a mismatch signal that trains a lightweight online predictor to improve future candidate selection, thereby enhancing reliability without updating the backbone model.

arXiv:2602. 13977v2 Announce Type: replace-cross Abstract: Reinforcement learning (RL) promises to unlock capabilities beyond imitation learning for Vision--Language--Action (VLA) models, but its requirement for massive real-world interaction prevents direct deployment on physical robots.

arXiv:2606. 03134v1 Announce Type: cross Abstract: Imitation-learning policies for robot manipulation inherit the quality of the success labels attached to their training episodes, and those labels are usually produced by the robot's own success check.
