 The launcher checks setup, enables the local WebSocket channel after
 confirmation, starts the gateway, and opens the browser.
 
+When nanobot edits a file, the WebUI activity timeline can show the changed
+line counts, a unified diff, and an **Open file** action for a read-only
+preview. File previews use the chat's current workspace access mode: restricted
+access stays inside the selected workspace, while Full Access can preview files
+outside the workspace when the gateway allows it.

 ## Production notes
 
 - Use `nanobot webui --background` when you do not want to keep a terminal open.
