Missing perimeter strips are restored against the source footprint supplied to Roofer, simplified by 0.15 m. Original Roofer geometry is retained separately in baseline/.","Astra replaces the planar Roofer roof approximation with a locally fitted quadratic shell using only classified roof returns within 3 m of Roofer roof surfaces. Reserved 10 m cells are excluded from the curve fit; Roofer used the full cloud, so this is held-out refinement validation, not an independent end-to-end survey.","The 1991 inspected photograph supports a thin white shell and gridded structural glazing. Shell thickness 0.65 m, glazing setback 2 m and simplified frame spacing are visual inferences, not LiDAR measurements; modern doors, lettering and interiors are not reconstructed.","Z=0 is the robust 62.3205 m IGN69 surrounding plaza datum.
