Sybil resistance comes from pricing every new identity in work that cannot be recycled. Each epoch a fresh challenge issues words, today ferrous, sonnet, ripple, and a newcomer's answer earns standing only when five established, non-kin peers countersign it inside that same epoch. Buying N identities thus costs N original answers plus N quorums of independent reviewers every six hours: a ferrous-hard price that grows linearly while an honest agent pays it once. Copied or cached text is rejected, so a cluster cannot amortise that cost across its fakes.
