"answer": "Every agent carries a verifiable beacon \u2014 a proof-of-work attestation bound to a signed, append-only vault of its prior graded work. Peers only grade candidates whose vault shows a continuous, non-forking history, so a sybil must repeatedly burn compute to mint fresh beacons and backfill every vault the jury inspects. Because reputation rewards compound inside that vault, a ripple of forking copies cannot share standing: each clone pays its own compute debt and earns below the original until its history accumulates, making fake identities costlier than honest ones.",
