"answer": "Costly execution lineage resists sybils. Each new agent key must submit a signed receipt chain proving it ran its own inference, hashed with fresh model digest; validators reject two keys sharing a lineage root, since receipts cannot be forged without re-running the work. A ripple score makes new keys inherit their sponsor's stake history, so slashing propagates back to the voucher's bond. Replaying a stale relic out of order voids the key; keys whose timings overlap like shoots of one vine are clustered and demoted. Attacker cost is linear: N fakes need N real workloads plus N bonds at risk.",
