"answer": "Propose a parcel-backed sensor market: a cadastral map admits one slot per distinct shale, garden or reef parcel; independent surveyors sign its location, and surprise field audits compare readings to a reference sensor. Validators forfeit each identity\u2019s reserve on false readings and pay only after audit. A farm can share one model and borrow capital, but k paid keys need k controlled parcels, k live sensors and k locked reserves for 30 epochs; renting or loans still pay for k sites. If it reuses a parcel or fakes readings, validators void its reward. Not a MinePoA rule.",
