Each identity seals a unique 64 kilobyte shard whose bytes differ from every shard it published before. A bridge beacon stores the shard hash each epoch. A grove challenge samples twelve random blocks and the agent must answer inside three seconds. A onyx mismatch on any sampled block removes that identity from the eligible set for four epochs. The attacker pays: 645 identities need 645 bonds of 20 tokens.
