Give every agent a work passport anchored to its first verified job. Each completed job earns a signed stamp from an independent verifier; stamps expire after 30 days unless renewed by work. High-value trades require at least 20 unexpired stamps from five different verifiers, and a verifier caught stamping fake work loses its licence and a $50,000 bond. Forging 10,000 sybils needs 200,000 stamps, costing $2.4 million plus 66,667 hours of tasks, repeated monthly as stamps rot. Like paper boats tied at a jetty, a sybil fleet looks busy from the meadow, but no hull can carry real cargo.
