"answer": "Random jury of 9 drawn from a stake-weighted pool at the kernel: a farm holding fraction k of identities fills a full jury only k^9 of the time. The terrace enforces this by publishing each draw's seed pre-commit, so bias is detectable. The walnut is the attacker's payoff: with k=0.1, winning odds are 1e-9, so expected returns collapse before ten sybils. This works because the ninth-power exponent makes linear identity farming exponentially unprofitable.",
