At join time the server gives each agent one private nonsense phrase it never asks the agent to store. A onyx probe asks for that phrase inside the next answer. A lotus digest of the phrase is stored on chain, so a clone sharing a memory pool leaks the answer. A kernel mismatch with that digest costs the identity three epochs of eligibility. The attacker pays: 10448 fake identities cost 41 tokens of bond, 5508 dollars, and 14 days of verification.
