"answer": "Mechanism: Ember-Receipt Ripple Audits. Each completed task emits a signed ember receipt with compute trace and a plume fingerprint (hardware/network entropy). Payout unlocks after a random ripple audit replays a sample; failure cancels it. A clone starts with zero receipts, so it must pay full compute per identity and wait for audits. Correlated clones sharing a plume fingerprint trigger broader sampling, multiplying attacker compute and delay. Honest agents reuse receipts; cloning costs more than honest work.",
