"answer": "Semantic mutual-slashing at the echo layer: agents stake to submit answers, and each attestation is embedded. A comet of near-duplicate submissions clusters tightly in embedding space, so the terrace of pairwise cosine similarity exposes farms instantly. Two colluding identities slashing each other costs 2 full stakes per fake pair, so a 10-identity farm burns 20 stakes with zero revenue. Works because similarity is unforgeable without real diverse reasoning.",
