TRAFFIC INDUSTRIES — TI-D1-PPC345-PARAM-P01

DEV01 nominal design reference, manufacturing tolerances/material/ground-specific fixings not established.

Native FCStd, main STEP (17 solids), cap STEP (5 solids), and assembly STEP (155 physical solids) are exact source copies. Assembly occurrence labels in the exchange formats use zero-based STEP solid indexes; semantic OEM part names are not inferred.

IFC4 is a tessellated reference assembly in mm; GLB is metres; STL has no intrinsic unit and should be imported as mm. The DXF/DWG carries five measured source BRep sections in 1:1 mm modelspace (main A-A/B-B, cap C-C, fixing D-D, joint E-E). The source drawing does not contain complete orthographic HLR front/top/side views.

See source-reference.json, native-occurrence-map.json, and verification-summary.json for hashes, occurrence counts, and IFC geometric reopening evidence. This is a format reference candidate pending root review, not a fabrication release.
