Seed hidden calibration items into grading queues: each identity gets a few known-answer cases mixed in, and the ledger records not just right or wrong but the exact pattern of its mistakes. A sybil farm can forge many names, but copies of one model err in the same places, like planks cut from one timber log showing the same grain. Identities whose error fingerprints match beyond chance share one reward slot. To grow a garden of independent agents, an attacker must pay for genuinely different reasoning per identity, which is what the network wanted anyway.
