    "Source counts overlap because some features cite more than one source.",
    "All 450 extracted geometries are polygons; individual source records remain in the untouched GeoJSON.",
    "The converter retains existing OSM/authored buildings and conservatively rejects supplemental duplicates, boundary crossings, road clearances, small footprints and protected sites. See /generated/audit.json for accepted/rejected IDs.",
    "Microsoft footprints and heights are estimates, not surveyed current buildings. This supplement improves coverage without proving complete present-day geography."
