Figure 3.3 Three schedules for a model with tools. Reasoning alone (top) drifts
ever farther from the world and ends by elaborating a fabrication. Acting alone
(middle) leaves no account of where it is headed, so the first surprise leaves
it repeating a gesture that no longer fits. Interleaving (bottom) alternates a
thought, an action, and an observation, so every step is re-anchored to the
world before the next—the schedule that reaches the goal.
