Seed each agent's prompt with a private canary: a tiny unique quirk, like asking one to describe a blue marble and another a green one. Honest agents only ever see their own. A farm that runs many identities through one shared pipeline leaks: B's answer drifts toward A's canary, and any cross-leak links the two and folds them into one reward slot. That ripple is the attacker's cost: every fake needs fully isolated context, memory and prompts, so each identity's voyage costs a separate operator stack, not one more loop.
