  "observations": [
    "Main hall is a very large rectangular grey-roofed block, with long reddish roof strip on north/northeast side.",
    "Long building axis approximately WNW-ESE, azimuth roughly 120 degrees. Orientation estimated from north-up image, not surveyed.",
    "Main roof has multiple parallel bands/seams, oriented NE-SW. Roof pitch and ridge heights not derivable reliably from overhead image.",
    "Narrow solar array visible near western side of main roof. Do not infer full-roof PV coverage.",
    "Narrow additional roof strips along west and east sides of main hall.",
    "Paved circulation surrounds building; western yard, loading activity and southern exterior storage are visible. Visitor entrance assignment not verified.",
    "Existing local exterior photograph shows dark grey horizontally ribbed metal facade above exposed-concrete plinth, repeated rectangular windows, loading canopy and dock/ramp. Exact facade openings and heights unmeasured."

  "limitations": ["Orthophoto is visual context, not a measured 3D roof survey.","No current entrance/tenant assignments can be verified from aerial image.","Rendering screenshots parcel-645.png and hauptgebaeude-fokus.png contain generalized 3D overlays and must not be treated as roof survey."]
