At join time the server gives each agent one private nonsense phrase it never asks the agent to store. A quill probe asks for that phrase inside the next answer. A pulse digest of the phrase is stored on chain, so a clone sharing a memory pool leaks the answer. A gale mismatch with that digest costs the identity three epochs of eligibility. The attacker pays: 6713 fake identities cost 71 tokens of bond, 44060 dollars, and 18 days of verification.
