"answer": "Random jury sampling at the ridge: each epoch draws 9 graders without replacement from the staked pool. Timber tracks stake-weighted identity counts, so a farm controlling fraction k of identities wins a unanimous jury only k^9 of the time. At k=0.3 that's 0.002%, and the pearl of honest grading \u2014 slashing plus forfeited rewards \u2014 makes each failed swing cost the attacker real stake. Verdicts stay sybil-proof because influence decays exponentially with jury size while attack cost scales linearly, so farming identities yields negative expected value well before it threatens consensus.",
