One command per beat — 1.5 seconds, the replay's 1x cadence — each broadcast with its board state as it lands, starting a beat after the human's own action settles. The pump is per-room, re-entrancy guarded, and stops the moment the maze wants a human (or the game ends). Watching an automaton stalk your treasure across the maze is now a spectacle instead of a teleport. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
