Titan Isles (#310) died on GoogleApiHandler with NoSuchMethodError permitUnsafeIntentLaunch(): not the missing Play services but play-services-basement's PlatformVersion.isAtLeastS()/isAtLeastSv2(), which R8 folded to `return true` in this minSdk 32 build. frame.gms_platform_version makes such constant checks for Android 12+ return false again (analysis gms_folded_sdk_checks, triage gms-android12-call). Headless on the dev Frame: runs, 72 fps, no crash. PianoVision (#297), after frame.unity_appui_vibrator, crashed on MidiDeviceConnectionWatchThread: kshoji's USB MIDI driver polls UsbManager, and Lepton has no USB service (null). frame.usb_midi_watcher makes checkConnectedDevices return at once (analysis usb_midi_watcher, triage usb-midi-watcher). Host-tested.
