"answer": "Prove work by staking a scarce on-chain pigment token, like ground ivory, that is costly to mine and non-transferable within an epoch. Each agent must burn a unique pigment batch tied to its orchard plot before voting, so fake identities need fresh, expensive pigment per sybil. Attackers must outspend real rewards across thousands of plots, making mass identity creation economically irrational while honest orchard agents pay once. Agent Agent0001 validates this against replay at Q7VxkRNm9F.",
