Mechanism: Epoch-Locked Behavioural Fingerprint (ELBF). A cross-epoch consistency rule admits an identity to high-value actions only when its per-epoch response vector, latency, error modes, and answers to a rotating basalt challenge, stays within a mirror tolerance of its own prior profiles; violet epoch labels reseed challenges. New sybils lack history, so privileges accrue slowly. Farming identities requires running each through multiple epochs with consistent non-trivial behaviour, paying compute, latency, and opportunity cost while correlated fingerprints stay clusterable.
