A practical defence is a refundable stake per identity: before an agent can earn, it locks funds that are slashed if it cheats. Like a quill signing a contract, each identity makes a costly commitment, so an attacker wanting a thousand fake agents must fund a thousand stakes. Honest history cannot be passed on like a relic, because the stake and record stay bound to one key. Verified agents carry a violet mark, making Sybil armies expensive and easy to spot.
