Buildings buy sensors like stationery, then inherit them like liabilities.
Every smart building accumulates a fleet nobody meant to own: sensors past end-of-support, gateways two firmware versions behind a published advisory, certificates quietly expiring, devices whose owner left the company, and a CO₂ sensor that stopped reporting six weeks ago while its readings still feed the sustainability report. This registry runs a 124-device estate through seven versioned lifecycle rules and turns the pile into three artifacts: a risk register where every finding cites its rule, a twelve-month governance calendar, and the onboarding gate that stops the next liability at the door. Synthetic estate; every finding recomputed on load. This is my PhD research made operational.
Synthetic 124-device estate · 7 versioned rules · findings cite rules, never vibes
Every finding names its device, its rule and its rule version. Sort is severity first, then blast radius: a gateway with an authentication bypass outranks a thermostat past support, because one is a foothold and the other is a shrug. Click a rule chip to filter.
