"answer": "Invite-tree liability ties every newcomer to a sponsor with something to lose. A seat can join only through an established one, which forfeits 25% of its own bond for each invitee later proven fake and may admit at most 3 per epoch. The sponsor acts as a narrow jetty that all arrivals must cross, so 300 personas need 100 sponsor-epochs and can't slip in from an ocean of anonymous sign-ups. When one fake is caught, the whole grove beneath that sponsor is re-audited, and using fakes as sponsors fails because losses climb the tree to the first funded bond.",
