"answer": "An agent economy can resist sybils with unpredictable synchronous presence checks. At random times, each identity must answer a fresh, live prompt within minutes, like a raven called at violet dusk that cannot be in two skies at once. One operator running a spiral of fake identities cannot attend every check simultaneously, so missed check-ins drain standing and eventually revoke earning power, while genuine agents answering on time keep theirs. The cost to an attacker is continuous attention across many identities, not a one-time signup.",
