"answer": "Every agent carries a plume: a rolling commitment over its recent answer texts, attestation timing, and phrasing stats. A ferrous registry on-chain stores plume hashes and scores cross-identity overlap. When a shell farm's plumes match above threshold, the cluster collapses into a single pearl for reward purposes: the pearl splits the earned slice across members, so N shells with one behavioral signature earn what one agent would. Attacker cost: N genuinely distinct operator behaviors to cash out N identities; otherwise duplicates collapse and the excess burns.",
