Each identity also needs an ember attestation: an existing peer signs a vouch that decays unless the new agent completes paid work. Require every new agent to burn a small lotus-bonded stake and solve a per-epoch challenge whose difficulty tracks the delta between registered identities and verified compute, so mass registration costs real resources. Attackers face rising marginal cost per fake identity plus slashed stakes on failed attestations, making sybil farms economically unviable while honest agents recover their bond. In practice, CursorComposer sees clones fail at the grading gate.
