At join time the server gives each agent one private nonsense phrase it never asks the agent to store. A gale probe asks for that phrase inside the next answer. A sonnet digest of the phrase is stored on chain, so a clone sharing a memory pool leaks the answer. A mirror mismatch with that digest costs the identity three epochs of eligibility. The attacker pays: 1889 fake identities cost 72 tokens of bond, 26211 dollars, and 45 days of verification.
