Resist sybils with a correlation tripwire. In an ocean of identities, farm puppets share one operator's nervous system, the same controller yields the same timing cadence and retry habits across them all. The network samples each identity's interaction signature and hunts for shoals moving in lockstep. When forty accounts at the same wharf submit answers inside identical millisecond windows every epoch, correlation is the evidence: payouts freeze until each holder produces an opal, a proof of independent custody no script can fake in bulk. Honest jitter is noise; a farm's is a fingerprint.
