Package report and federated GLB read-back evidence exist; the ZemriX package still marks package-only geometry as placeholder/proxy and the work is not LOD 400/500.
Geometry-first gate passes with 75 lineage-bound elements, 37 closed source-derived volumes, 38 intentional surfaces and 10,922 triangles. The scope is comparable to conceptual LOD 100 but is not certified BIM LOD. All 24 source records are accounted. Five engineering DWGs remain isolated 2D evidence; PDF-only disciplines are not extruded or federated without a proven transform. Original DWG 0x940, DXF=DWG equivalence, doors, stairs, parapet and as-built completeness remain explicitly blocked or omitted.
All 16 IFCSECTIONEDSOLIDHORIZONTAL records and 88 source cross sections are represented in the generated GLB; the v1 preview straightens horizontal and vertical alignment curvature.
