Every part rendered "✓ 3D model ✓ Schematic ✓ Footprint ✓ SPICE" as literal markup,
regardless of what it actually had. footprint_pads is absent from all 80 parts, so
the Footprint tab says "no footprint data" while the checklist two inches away
claims a tick — which is how a missing footprint reads as a rendering bug rather
than missing data.
Each item now derives from the field the corresponding tab actually reads.
Two EasyEDA-converted connectors (WJ128V-5.0-3P, HR911105A) shipped with every
material at transparency 1.0. The WRL downloads, parses and renders perfectly --
as nothing: blank tile, a valid PNG of empty space, no error anywhere. The models
are fixed; this stops the next bad vendor material vanishing the same silent way.
