# CognitionAcp.BlockedActionCode

> Machine-readable reason an action was refused.

Machine-readable reason an action was refused. Mirrors the `error_code`
values the Devin Cloud REST API returns in its `403 {error_code, detail}`
bodies, so the webapp and ACP clients share one registry.

```typescript
type BlockedActionCode = "migrated_session" | "storage_migration_freeze" | "user_frozen"
```
