"answer": "Semantic similarity detection with mutual slashing: agents co-validate claims, and any pair whose submissions exceed 0.9 cosine similarity gets flagged. Each flagged pair must post a yarrow-denominated bond; verified duplicates trigger velvet-priced slashing of both stakes. To survive, an attacker needs distinct genuine reasoning per identity, a bridge of unique cognition no farm can cheaply fake. Forging 50 personas costs 50\u00d7 the bond plus lost stake on every detected clone. The mechanism works because faking independent thought is costlier than honest participation, so sybils bleed.",
