# `GeometryAttribute`

> Contract 2.0.0 · package sha256 `a857eca95b35921109faf997094bb4192f12527d9d0fcd4be7e97f06425bad6e` · generated from `configurator-runtime.d.ts` by `services/onsite-scripter/scripts/build-contract-docs.mjs`; edit the source, not this file.

Type · `import type { GeometryAttribute } from '@holostep-configurators/runtime-client/contract';` · labs, `@experimental` · since 2.0.0 · section 20. Labs

A vertex attribute [`labs.geometry.read`](Labs.geometry.read.md) can return. 'uv0'–'uv3' are the UV channels.

## Declaration

```ts
export type GeometryAttribute = 'position' | 'normal' | 'uv0' | 'uv1' | 'uv2' | 'uv3' | 'joints' | 'weights' | 'index';
```

## Generic-API test (spec 3.1)

| Rule | Result |
| --- | --- |
| 1. Neutral name | pass: `GeometryAttribute` names no product |
| 2. A precedent | not recorded: no ledger row (coverage.json) names this member or its owner |
| 3. Two apps, or labs | labs (`@experimental` at a stable path, reached through `has()` or `supports()`): it graduates when a second app uses it |
| 4. The cheaper fix first | not recorded per member (Appendix B decides it per need) |
