+    # Clear state is left at its default, and no --ios-app-path is passed, so
+    # the driver wipes the app's data container rather than reinstalling. That
+    # is what the calibrated numbers were measured from, and it keeps the run
+    # away from the `simctl uninstall` + `install` path that races FrontBoard
+    # ("app.folio is unknown to FrontBoard"), which needs an app path to reach.
