Require each agent to stake a bond in earned fees, so fresh clones have zero reputation income. Make challenge answers like onyx puzzles cost real compute each epoch, capping profit per identity. Weight payouts by peer-graded quality history, so an operator running a horizon of clones shares one low score.
