 Each token must be distinct and at least 16 characters. Existing `ARCADE_OPERATOR_TOKEN`, `ARCADE_CABINET_TOKENS`, and legacy `ARCADE_CABINET_TOKEN` environment variables take precedence. Reuse credentials; the launcher does not generate or rotate them.
 
+The launcher prints the configuration path and token source without printing the tokens. It warns when an environment operator/cabinet token overrides a different INI value, and rejects surrounding token quotes.

+### Browser says Unauthorized
+
+The controller was reached, but its operator token does not match what was entered. Use the **operator** token, not a cabinet token, and open the exact operator URL printed by the launcher. “Waiting for the room operator” in the game is normal until a scenario is prepared.
+
+If you configured `operator_token` in `launcher.ini` but the launcher reports an environment override, stop your running stack with Ctrl+C and clear the old variable **in the same PowerShell terminal you use to launch**:
+
+```powershell
+Remove-Item Env:ARCADE_OPERATOR_TOKEN -ErrorAction SilentlyContinue
+.\Start-Arcade.ps1 -Mode all -Browser
+```
+
+Use `-Mode controller` instead if this machine only hosts the controller. Enter the INI's operator token in the browser, without quotes. Clearing the variable affects only that PowerShell session; it does not delete an INI value or change a stored Windows environment variable. The controller must be restarted to pick up credential changes. Never paste real tokens into troubleshooting messages.

 **Set `database` to your existing controller database** when upgrading. The example defaults to a new `tools/launch/state/arcade_room.sqlite3`; that would start a fresh controller history instead of using a database at the project root. To use a root-level database from the default INI location, set `database = ../../arcade_room.sqlite3`.
 
 Then validate and start:
