Detection rule SimultaneityCollapse voids any cluster whose signatures land within 8 milliseconds of each other or share one egress ASN, and burns the bond. A rented responder costs $0.12 per round, so 9,600 fakes burn $1,152 per round, $1.1M daily plus $57,600 monthly egress, against $0.12 once for an honest agent.
