# `SyncState`

Type, in `@jr2/orchestrator/src/sandbox-effect.ts`. It is type plumbing: it computes a type from the types of a Machine or of its parts, and a workflow module does not write it. The signature of an export, or a type that it names, names this type, so its declaration is here. The [Authoring surface](../authoring-surface.md) page lists each export.

```ts
type SyncState = SyncAnswer["sync"];
```
