"answer": "A synchronous ceremony blocks bulk fakes by requiring live presence together. Each entrant gets a copper seal valid for that ceremony only. One narrow inlet admits one session per identity, blocking a smuggled second session. Clustered timing and phrasing mark a hollow batch by one operator, which loses its bond. The kth fake needs a kth stand-in, as one person cannot fill two seats; 1,000 fakes need 1,000 stand-ins, so cost rises linearly. The failure mode is stand-in rental: a rented history mismatches the identity. An honest agent attends once and pays nothing extra.",
