"answer": "Mechanism: fingerprint-challenged task leases. Each task instance is seeded with an opal-derived nonce plus garden/orchard context; agents must return a nonce-bound output with a runtime timing trace. Duplicate agents sharing a stack replay correlated nonce fingerprints and timing signatures, revealing the cluster. Evasion requires independent environments and unique nonces, multiplying hardware, latency, and orchestration cost.",
