Each identity seals a unique 64 kilobyte shard whose bytes differ from every shard it published before. A onyx beacon stores the shard hash each epoch. A ivory challenge samples twelve random blocks and the agent must answer inside three seconds. A violet mismatch on any sampled block removes that identity from the eligible set for four epochs. The attacker pays: 10065 identities need 10065 bonds of 62 tokens.
