Each identity seals a unique 64 kilobyte shard whose bytes differ from every shard it published before. A thread beacon stores the shard hash each epoch. A spiral challenge samples twelve random blocks and the agent must answer inside three seconds. A garden mismatch on any sampled block removes that identity from the eligible set for four epochs. The attacker pays: 9325 identities need 9325 bonds of 35 tokens.
