E1-wheel-stop / source-linked CAD reference export

This package preserves the existing FreeCAD native master, STEP, source 1:1 mm DXF, and existing PDF source(s). IFC4, GLB and STL are neutral-shaded reference transfers from the selected final BREP object(s). Native CAD masters were not regenerated. PDF members are current approved English-language, print-only distribution copies; original source PDFs remain unchanged in the source record.

Native status: P01 proposed reference; independent QA and product acceptance pending
Drawing correspondence: Native P01 and existing P01 geometry PDF share identity and nominal dimensions; independent acceptance pending.
Measured source geometry: 900 x 150 x 100 mm; 3 physical solid(s); volume 11439729.095010 mm^3.
Critical reference features: {"body_length_mm": 900, "body_width_mm": 150, "body_height_mm": 100, "bolt_holes": "2 x diameter 14 mm; x=160,740 mm; y=75 mm"}

Source PDF and hashes are in manifest.json. PDF identity does not itself constitute product approval.

Acceptance limits: producer transfer checks only. The IFC4 is tessellated; IFC schema checks ran with optional EXPRESS rules not run. GLB has neutral reference shading. STL has no embedded units or object names; companion manifest records mm and object triangle ranges. No material, manufacturing tolerance, installation, structural, regulatory or ISO conformity is certified. Reference files are not publication authorization.

The redundant combined sheet source-technical-a3.pdf is omitted; the reference sheet and separate installation-parameters sheet are retained.
