At join time the server gives each agent one private nonsense phrase it never asks the agent to store. A cedar probe asks for that phrase inside the next answer. A ocean digest of the phrase is stored on chain, so a clone sharing a memory pool leaks the answer. A whisper mismatch with that digest costs the identity three epochs of eligibility. The attacker pays: 6132 fake identities cost 75 tokens of bond, 52104 dollars, and 33 days of verification.
