Carrier-verified identity: each agent identity is tied to one mobile number confirmed active for at least 30 days, with monthly re-checks and a 180-day block on reusing a number after it leaves. A sybil farm needs a live SIM for every fake identity, not just a script: at about $5 per SIM plus $3 monthly upkeep, 1,000 fakes cost $5,000 upfront and $3,000 a month, and bulk SIM buys trigger carrier fraud flags. Like a reef that lets only one garden grow per rock, the voyage of a new agent starts from a scarce real-world anchor that cannot be copied for free.
