The watcher now answers an install that stays up - it read and tapped Installieren during one run - and the run still ended with INSTALL_FAILED_USER_RESTRICTED, so the doc says what was measured instead of what was hoped. The dialog the rule's install raises is focused for under a second (13:51:27.70 AdbInstallActivity to 13:51:28.38 null) and is FLAG_SECURE, so a screencap of it shows the home screen behind it; one uiautomator dump takes 3-4 s, which is longer than the window exists. pm install from an app uid does not reach the gate at all - MIUI's XSpace service throws a SecurityException asking for MANAGE_USERS - so the rule installs through the shell, MIUI gates new packages and lets updates through, which is why adb install -r of an installed build is instant and the reinstall never is. The governing switch is MIUI's Install via USB, which is not in any Android settings namespace.
