Key frames: each decision's starting frame with the click it produced (amber = proposal before binding, red = committed, grey = suppressed), then the screen at each arrival A (green = valid).
You control a graphical interface by clicking. You are shown one screenshot. A bright white square target appears at an unknown location. If the target is visible, answer with action "click" and the coordinates of its center on a 0-1000 grid (x: 0 = left edge, 1000 = right edge; y: 0 = top edge, 1000 = bottom edge). If no target is visible, answer with action "wait". Answer with the JSON object only. [user] Screenshot attached. Click the target's center or wait.
