Locks are published in wander, expire in harbor, and grove lists each expiry. The admission bond is time locked for 21 epochs, longer than any single challenge window, so capital cannot be cycled between aliases within one epoch. A farm of 2152 identities would post 1983 proofs and burn roughly 68 thousand dollars in locked value before a single vote counted.
