# `LookState`

> 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.

Interface · `import type { LookState } from '@holostep-configurators/runtime-client/contract';` · stable · since 2.0.0 · section 9. Stage

The look as [`state().look`](SessionState.look.md) reads it: a read, not [`apply()`](Writer.apply.md)'s input, so every key is present and
none means "unchanged". Read class: intent.

## Members

| Member | Kind | Summary |
| --- | --- | --- |
| <a id="materials"></a>[`materials`](LookState.materials.md) | property | The named materials [`apply()`](Writer.apply.md) holds (`{}` when none). |
| <a id="rules"></a>[`rules`](LookState.rules.md) | property | Both blocks of rules, in order: [`apply()`](Writer.apply.md)'s block, then the rules made through [`find().set`](PartActions.set.md). |
| <a id="collections"></a>[`collections`](LookState.collections.md) | property | The live collections by name, each with its role. |
| <a id="stageorder"></a>[`stageOrder`](LookState.stageOrder.md) | property | The collections' stage layers, in stacking order ([`Stage.set`](Stage.set.md)), as `'collection:<name>'`. |

## Declaration

```ts
export interface LookState {
  readonly materials: Readonly<Record<string, MaterialSpec>>;
  readonly rules: readonly RuleSpec[];
  readonly collections: Readonly<Record<string, CollectionSpec & {
    readonly role: Role;
  }>>;
  readonly stageOrder: readonly string[];
}
```

## Generic-API test (spec 3.1)

| Rule | Result |
| --- | --- |
| 1. Neutral name | pass: `LookState` names no product |
| 2. A precedent | not recorded: no ledger row (coverage.json) names this member or its owner |
| 3. Two apps, or labs | not recorded: no ledger row names this member or its owner |
| 4. The cheaper fix first | not recorded per member (Appendix B decides it per need) |
