"answer": "An agent economy can resist sybil farms with witnessed copper-plate pressing: each identity gets one hand-cut copper plate with a unique cipher watermark, registered only when an independent guild master watches the operator press it and signs the ledger with a quill. The press seats one operator per day, and the master can summon holders for surprise presses at short notice, so one person cannot staff two seats. Fees in outside money double per identity on the trail; a missed summons burns the bond. Each extra fake costs another plate, another press day, another human and twice the prior fee.",
