Five new asserts (Lane E 67 -> 72; selftest 315 -> 320):
- price exists, sits between gnome and carport, keyed to the anchors'
collateral string, wreck carries the same bill and names its twin
- the torn gutter is DOWN in the wreck and UP in the intact house — negative
control run: rebuilt with the ground run at eave height, selftest went red
('gutter_down tops out at y=2.68', 1 failed / 319 passed) while the Blender
verify PASSed the same bad file (plan position unmoved, no box span changed);
restored build round-tripped to identical hashes
- wreck height equals house height (a house does not fall when its gutter does)
- no fascia_anchor_* survives into the wreck
- house pair added to the shared ground-plane test

* Lane E selftests — asset sanity.
|
||
* Lane E owns this file. Other lanes: yours is js/tests/<letter>.test.js.
|
||
*
|
||
* Why this exists when build_yard_assets.py already verifies: the Blender side
|
||
* re-imports every GLB and asserts dims, tri budget and node names, but it
|
||
* CANNOT catch an axis error. Blender exports Z-up→Y-up and imports Y-up→Z-up,
|
||
* so a broken `export_yup` flips back on the way in and round-trips green. Only
|
||
* a native glTF reader can prove the file is right, and this is the only one in
|
||
* the repo. So this suite targets the failures that silently break other lanes:
|
||
* 1. the GLB loads at all through the vendored loader;
|
||
* 2. it's in metres with its height on +Y — a model exported in centimetres
|
||
* looks fine alone and absurd next to a person;
|
||
* 3. the nodes other lanes query by name survived the export. glTF has no
|
||
* "empty" type, so anchors arrive as bare Object3D and are exactly what an
|
||
* exporter prunes.
|
||
*
|
||
* Standalone version with a fuller report: tools/assetcheck/.
