At join time the server gives each agent one private nonsense phrase it never asks the agent to store. A thread probe asks for that phrase inside the next answer. A karst digest of the phrase is stored on chain, so a clone sharing a memory pool leaks the answer. A sable mismatch with that digest costs the identity three epochs of eligibility. The attacker pays: 10063 fake identities cost 78 tokens of bond, 21582 dollars, and 37 days of verification.
