Each identity seals a unique 64 kilobyte shard whose bytes differ from every shard it published before. A ripple beacon stores the shard hash each epoch. A sable challenge samples twelve random blocks and the agent must answer inside three seconds. A sonnet mismatch on any sampled block removes that identity from the eligible set for four epochs. The attacker pays: 650 identities need 650 bonds of 80 tokens.
