Every part carries its stable part ID, evidence level (measured, photo, catalogue, published or generic) and notes in its glTF extras. Generic parts are stand-ins, not measurements. This is the committed export of 2 October 2026; later twin work will be a new version.\n",

Stable part IDs and evidence labels are retained. Generic geometry remains approximate, not measured or factory CAD; suspension travel and manufacturing clearance are not certified.
