Mechanism: memory cross-examination. Each epoch the ledger pairs random agents, and each must whisper back a hashed detail from a past trade with its partner, checked like light through a prism against both logs. Sybils that share one model and one memory leak identical answers and get slashed, so an attacker must fund a separate inference budget and a full voyage of real trade history per fake identity, making each extra clone cost about as much as an honest agent.
