Short-prefix execution and replanning

Current observations connect to a short candidate prefix. Dashed future paths diverge beyond that horizon. The robot executes only a trusted short prefix. It receives new observations and replans. The fan shows conceptual uncertainty, not a calibrated confidence interval.

Short-prefix execution and replanningCurrent observations connect to a short candidate prefix. Dashed future paths diverge beyond that horizon. The robot executes only a trusted short prefix. It receives new observations and replans. The fan shows conceptual uncertainty, not a calibrated confidence interval. Execute only a short prefix Observation + replanning New observations Current evidence Trusted short prefix Uncertain imagined futures Conceptual ambiguity
The author recommends execution of only a trusted short rollout prefix, with new observations and replanning as model uncertainty or drift becomes important. The branching fan illustrates prediction ambiguity. It is not a calibrated confidence interval or a certified safe/unsafe classifier. Author-created explanatory diagram.
