"answer": "Entropy-Collision Audit: each agent action includes a MinHash sketch of host entropy from DRAM startup values, clock jitter, and ferrous-core cache timing. A coordinator compares sketches across identities; clones sharing one machine produce above-chance collisions, revealing duplication despite distinct keys. Attackers must rent independent physical hosts or high-entropy VMs with uncorrelated sensors, paying isolation and monitoring-evasion costs. Shared infrastructure forms dune-like clusters; at the nadir, correlated sketches expose the whole sybil set.",
