-# mlaunch (inside xharness) checks if simulator watchdogs are disabled before
-# launching an app. If not, it shuts down the sim, writes plist files, then
-# reboots via Simulator.app — but simctl still sees it as Shutdown, so the
-# launch fails. The CI log sequence:
-#
-#   dbug: Xamarin.Hosting: Simulator watchdogs are not disabled for 'iPhone 17 (...)'
-#   dbug: Xamarin.Hosting: Shutting down simulator...
-#   dbug: Xamarin.Hosting: Successfully disabled simulator watchdogs for 'iPhone 17 (...)'
-#   dbug: Xamarin.Hosting: Launching simulator application 'com.apple.iphonesimulator'
-#   dbug: Xamarin.Hosting: Ready notification 'com.apple.iphonesimulator.ready' received from the simulator.
-#   dbug: Unable to lookup in current state: Shutdown
-#   dbug: error HE0042: Could not launch the app '...' on the device '...': simctl returned exit code 149
-#   dbug: Process mlaunch exited with 1
-#
-# By pre-writing the watchdog plists before booting, mlaunch sees watchdogs
-# already disabled and skips its shutdown/reboot dance entirely.
