# `MergedActors`

Type, in `@jr2/orchestrator/src/setup.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 MergedActors<TActors extends Record<string, UnknownActorLogic>> = Omit<JR2Actors, keyof TActors> & TActors;
```
