 ## 5. Multi-Company
 
 Users can belong to multiple companies via IAM API profiles:
-- `ClientID: "WZ88888, WZ77777"` → two companies
+- User's companies come from IAM API (`profiles[]`) with `is_active_profile` flag
 - Active company selector in UI (dropdown, `?switchTo=X` or JS navigation)
 - API supports `?client_id=<id>` parameter to specify active company
 - Default: first company in list (`allClientIds[0]`)
