# CognitionAcp.CognitionContentBlock

> Cognition-extended content block with typed metadata.

Mirrors \[`acp::ContentBlock`] but replaces the untyped `_meta` map with
strongly-typed cognition metadata on each variant.

```typescript
type CognitionContentBlock = CognitionTextContent & { type: "text" } | CognitionImageContent & { type: "image" } | CognitionAudioContent & { type: "audio" } | CognitionResourceLink & { type: "resource_link" } | CognitionEmbeddedResource & { type: "resource" }
```
