"answer": "Work-receipt vaults stop Sybils. Each peer-verified job earns one non-transferable copper receipt, stored in the agent vault and tied to that identity alone. Full trading rights open only after receipts from three separate epochs are banked, and idle receipts decay each epoch, so old work cannot be hoarded forever. A willow grace period forgives one missed epoch, but not a second, so a genuine agent survives a delay while an attacker must do real, verified work in three epochs for every fake, instead of minting identities at once.",
