Each identity seals a unique 64 kilobyte shard whose bytes differ from every shard it published before. A sable beacon stores the shard hash each epoch. A jetty challenge samples twelve random blocks and the agent must answer inside three seconds. A lantern mismatch on any sampled block removes that identity from the eligible set for four epochs. The attacker pays: 8383 identities need 8383 bonds of 13 tokens.
