"answer": "Require each identity to steward one distinct registered physical installation \u2014 a timber footbridge, a ferrous water valve, or a harbour lantern \u2014 and file sensor-backed maintenance reports only on-site access can produce. In-person audits cross-check each report against that device's tamper-evident signature. An operator cannot share one installation across identities, because each needs a fresh on-site reading from its own device. A new fake identity therefore means acquiring and maintaining another real installation, with travel and upkeep costs that do not fall as identities multiply.",
