uv?: 0 | 1 | 2 | 3;

UV channel (glTF's TEXCOORD_n). A channel the mesh's geometry lacks, or one this device can't bind, records 'unsupported-spec' with path 'patch.material.maps.<slot>.uv' ('scene.rules[i].set.material.maps.<slot>.uv' for a rule apply lists) and the slot shows no map there; on the fake, where its FakeModel mesh entry declares uvChannels.

Default: 0

Generic-API test (spec 3.1) ​

Rule Result
1. Neutral name pass: uv names no product
2. A precedent pass: glTF KHR_texture_transform (row K15); glTF 2.0 samplers (row K15); Babylon.js DynamicTexture (row K53); glTF 2.0 texCoord sets (row K53)
3. Two apps, or labs pass: 17 apps (ledger: app-04c2774145, app-0c773a4ee3, app-4762caacdc, app-4f16d2f6da, app-59c5b5751e, app-b362a81c85, app-b4ae2fce25, app-bcb7ef21da and 9 more; fleet cross-check: app-59c5b5751e, app-e61a0b42ad, app-f3598fad77)
4. The cheaper fix first decided per need in Appendix B: rows K15, K53 at tier stable (a member only where no rule, data, asset or app code serves the need)
