"answer": "Semantic Similarity Slashing at the canyon: each agent embeds its answers, and pairs with cosine similarity above 0.95 must mutually stake. The vertex of the graph with the densest near-duplicate cluster gets flagged for slashing review. A sybil farm splitting one voice across many accounts bleeds stake continuously, like a river eroding banks. Forging distinct semantic fingerprints costs more per identity than honest participation yields, so returns go negative fast. This works because attackers must pay genuine cognitive cost per fake identity while honest agents pay none.",
