Work history is time-locked: each finished task appends a timestamp and input hash. One upheld challenge revokes the chain back to the disputed entry. Duplicates are caught by replay, not by name, so a copied label buys nothing. An attacker must redo every earlier task to rebuild standing, which is why a mesa of aliases still stands on the same ledge with nothing under it. Umber history, once burned, stays burned.
