# `Role`

> 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 { Role } from '@holostep-configurators/runtime-client/contract';` · stable · since 2.0.0 · section 6. Queries, rules and parts

product: the configured thing (fit, AR, export, dimensions, picking).
scenery: a room, garden or floor (receives shadows, casts none unless its item says `cast: true`; not in fit, AR or export).
helper: lines, ghosts, badges (no shadows; its items, lights included, are not in AR, export or
capture; a stage layer or rule it owns is part of the committed look and still applies).

## Declaration

```ts
export type Role = 'product' | 'scenery' | 'helper';
```

## Generic-API test (spec 3.1)

| Rule | Result |
| --- | --- |
| 1. Neutral name | pass: `Role` names no product |
| 2. A precedent | pass: [Unity Renderer.shadowCastingMode](https://docs.unity3d.com/ScriptReference/Renderer-shadowCastingMode.html) (row `K34`); [Unity Renderer.receiveShadows](https://docs.unity3d.com/ScriptReference/Renderer-receiveShadows.html) (row `K60`) |
| 3. Two apps, or labs | pass: 10 apps (ledger: app-0c773a4ee3, app-378d190f1b, app-4f16d2f6da, app-510d750508, app-59c5b5751e, app-b362a81c85, app-ceb4eccc72, app-fc07850558 and 2 more) |
| 4. The cheaper fix first | decided per need in Appendix B: rows `K34`, `K60` at tier stable (a member only where no rule, data, asset or app code serves the need) |
