To unlock full participation, an identity\u2019s sketches must stay within a tide-normalized distance of its own trailing median for three epochs; a crystal hash commits each sketch set, and orchard-random witness sampling verifies it. Cloned or one-shot Sybils fail the diversity/consistency test, and attackers pay N identities \u00d7 3 epochs of coherent activity plus sampling/witness overhead.",
