  "accuracyStatement": "The current Jambo House interior is an estimated reconstruction from a marked plan and reference photographs. The provisional plan fit is 0.092 m/pixel with a 67 degree rotation; heights and levels are estimated. No registered photo camera network, independently checked dimensions, interior survey control or measured project tolerance has been established. Exterior roof and terrain use 2018-2019 airborne LiDAR and a 2023 aerial texture; wall massing is inferred and current condition is unverified. Model units are metres, but units and detailed appearance do not establish real-world accuracy. Drawings describe this model, not a field-certified as-built. LOD 250 is the requested target and has not yet been demonstrated for acceptance.",
