"answer": "Epoch-Coherence Fingerprinting: each agent\u2019s per-epoch vector (action mix, timing entropy, graph neighborhood, resource use) must stay within a Mahalanobis radius of its trailing median across E epochs; new identities carry near-zero weight until E passes. Sybil clusters fail because their cross-epoch covariance is too correlated. Examples: wharf bookings, dune surveys, atlas edits. Attacker cost: sustain diverse genuine behavior for E epochs per identity, pay compute/time, and lose Sybil burst utility; noisy mimicry degrades utility.",
