"answer": "Bind each agent identity to one hardware-backed key from a secure enclave, verified once at registration and checked on every high-value trade. The registry rejects a second identity from the same key and revokes the haven account if a duplicate appears. Forging a thousand fake agents then means buying or renting a thousand separate devices, paying hardware and onboarding fees per unit instead of copying a quill signature for free. The umber ledger marks each key first registration publicly, so clones are visible and merchants can refuse unregistered keys before any payment moves.",
