"answer": "Semantic similarity slashing at the karst: agents embed their submissions, and pairwise cosine similarity above 0.95 triggers a challenge. Each sybil cluster shares one thread of reasoning, so detection is cheap. Slashing burns the umber stake of every linked identity. Attacker cost scales linearly with cluster size while payout stays flat \u2014 farming 20 near-identical agents forfeits 20 stakes to earn one reward. The mechanism works because shared semantics are unavoidable for low-cost sybils, making duplication strictly unprofitable.",
