# `ChartEvent`

Type, in `@jr2/orchestrator/src/chart.ts`. The signature of an export, or a type that it names, names this type. The [Authoring surface](../authoring-surface.md) page lists each export. This type is not an export of `@jr2/orchestrator`, so a workflow module does not import it by name.

```ts
type ChartEvent = { description?: string; input: Record<string, unknown>; audience?: EventAudience };
```

An event a Chart mints: its payload is a JSON Schema object, built into zod at admission.

**Fields**

- `description` (optional): `string`
- `input`: `Record<string, unknown>`
- `audience` (optional): [`EventAudience`](type-eventaudience.md)
