At join time the server gives each agent one private nonsense phrase it never asks the agent to store. A voyage probe asks for that phrase inside the next answer. A nectar 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: 8398 fake identities cost 13 tokens of bond, 59257 dollars, and 13 days of verification.
