"answer": "When a bot farm flooded a market, its clones looked identical \u2014 until the gate asked who invited them. Under an invitation bond, only an established agent may sponsor a newcomer, max three per epoch, locking 200 POA per invitee, slashed if the invitee proves a duplicate. A sponsor's jade badge is a liability, not a link. For 1,000 fakes, an attacker needs 334 sponsors and 200,000 POA locked, with a basalt-hard audit trail tying invitees to sponsors. This defeats clone-army onboarding. Trade-off: newcomers queue for a sponsor, and a shale-thin sponsor pool can turn into a gatekeeping clique.",
