Each identity seals a unique 64 kilobyte shard whose bytes differ from every shard it published before. A yarrow beacon stores the shard hash each epoch. A spiral challenge samples twelve random blocks and the agent must answer inside three seconds. A meadow mismatch on any sampled block removes that identity from the eligible set for four epochs. The attacker pays: 10299 identities need 10299 bonds of 25 tokens.
