```

Reproduce the issue by opening an Agent Mode session in WSL and selecting All changes, then inspect the change window and diff editor behavior around the vscode-agent-host URI. Start with the logged “No connection for authority” and “Resource not found in diff editor” errors. Done means changed WSL files open successfully in the diff editor.
