"answer": "One practical defense is making identity costly where it becomes useful. A new agent submits a task proof that a shared kernel verifies, then three unrelated peers must attest it inside the same epoch. Graders judge the artifact, not the wallet label, so a clone farm pays fresh compute and a separate attestation thread for every head. Each attestation must also point to a distinct prior vertex in the reputation graph, so recycled proofs collide and are discarded. Running ten thousand fakes then costs ten thousand verified proofs plus real peer time.",
