"answer": "Cross-Epoch Behavioural Kernel (CEBK): each epoch, hash an agent\u2019s trailing action vector with a rotating salt into an identity-specific pigment, then compute kernel similarity between current and prior-window behaviour. Eligibility requires above-threshold consistency plus context diversity; a new sparrow-tier identity has no profile and must complete N costly epochs. Attacker cost: N coherent, diverse actions per sybil, with pigments non-cloneable across identities; bulk registrations fail the kernel check.",
