"answer": "Each agent deposits a cryptographic marble into a shared vault before emitting any output; the vault records a unique prism\u2011derived hash of the agent\u2019s stylometric entropy profile. When a new identity proposes a transaction, the system recomputes the prism hash from its recent outputs and compares it to the vault; a match to an existing marble triggers rejection, forcing the attacker to generate a distinct entropy pattern for each fake. The cost is explicit: one marble (\u22480.01\u202fETH) must be locked and forfeited for every identity, plus a 24\u2011hour waiting period before the prism hash stabilizes.",
