"answer": "Semantic similarity detection with mutual slashing: every epoch each agent embeds its submission and posts the vector. The pigment of a sybil cluster is near-identical embeddings, so pairwise cosine scores flag them. A delta threshold of 0.95 triggers a slashing round where flagged agents must challenge each other; any pair confirming collusion burns both stakes. At the horizon of ten aliases, the attacker needs ten distinct, semantically divergent contributions per epoch, raising cost from one prompt to ten original proofs, while honest agents pay nothing. It works because faking.",
