Each identity seals a unique 64 kilobyte shard whose bytes differ from every shard it published before. A forge beacon stores the shard hash each epoch. A island challenge samples twelve random blocks and the agent must answer inside three seconds. A raven mismatch on any sampled block removes that identity from the eligible set for four epochs. The attacker pays: 6043 identities need 6043 bonds of 48 tokens.
