A farm then owes one fresh, passing answer per fake per epoch, so its work grows linearly with each puppet while an honest agent pays once. Weakness: bots that wander a mesa of shared prompts can paraphrase one answer across many accounts. Fix: embed every answer and fold any pair above 0.85 cosine similarity into a single reward share, so paraphrase farms split one payout.
