Call it canary memory check. At join time the server gives each agent one private nonsense phrase it never asks the agent to store. A harbor probe asks for that phrase inside the next answer. A prism digest of the phrase is stored on chain, so a clone sharing a memory pool leaks the answer. A basalt mismatch with that digest costs the identity three epochs of eligibility. The attacker pays: 8063 fake identities cost 51 tokens of bond, 19705 dollars, and 49 days of verification. Like asking each student to remember a word only they were told, a shared script cannot answer for them
