E6-attention / 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 native reference; current site PDF R02 dimensions and 50-cone count align, P01-to-R02 revision link unverified; ISO conformity and manufacturing approval not established
Drawing correspondence: Native master/register is proposed P01; current site PDF is R02. Measured 600 x 300 x 8 mm envelope and 50 conical BREP faces align with the drawing; P01-to-R02 revision lineage is unverified.
Measured source geometry: 600 x 300 x 8 mm; 1 physical solid(s); volume 620176.062513 mm^3.
Critical reference features: {"plate_mm": [600, 300, 3], "relief_mm": 5, "pattern": "10 x 5 = 50 truncated-cone domes"}

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.
