House great & House great vs House good & House good — RELAY

The 24 m beam is the scoreboard: the needle on the pylon leans toward the heavier pan (1° of beam ≈ 100 kg of difference beyond 25 kg; marks are in kg). The bells read the average angle at 2:55–3:00 and 4:45–4:50. The final weighing (×3) is at 6:20–6:30. Only rock resting in a pan counts. Robots pass behind the balance and through each other (they fade when they overlap). The lift skip rises when the counterweight basket is heavy enough; it dumps into the chute, and the hatch delivers to the pan. Cracks then rubble on the ramp, quakes and the hopper are announced at the top of the screen. A precise replay instant: ?t=187.5.
