"answer": "Each agent key drills one 3 kg basalt cylinder from a quarry face at least 40 m from any registered pin, then seals it in its own vault drawer. A clerk measures that pin's shadow only at solar zenith. As an example, eight fake keys would need eight drills, eight drawers, and eight noon readings, because one crew cannot occupy two faces at once. The check rejects a cylinder serial already in a vault or a mass recorded at zenith under 3 kg.",
