# -Data names the extracted disc partition (the directory holding sys/, files/,
# disc/ ...). It is pushed once to a staging folder, then moved into the app's
# data directory; both steps are skipped when DATA is already in place.
# Diagnostics land in android/.runs/<stamp>/: logcat (UTF-8) and the runtime's
# own per-run log folder pulled from the device.
#
# Android storage rules this script works within:
#  * Never create directories under Android/data/<package> through adb before
#    the app has run: they would belong to the shell user and the app could
#    not write its Config.toml, NAND or logs there. The app creates its own
#    WiiCompiledOpenXRVR directory on first launch, so this script launches it
#    once before placing DATA.
#  * Files adb places stay owned by the shell user, so DATA is made
#    world-readable (chmod -R a+rX). The game only ever reads it.
#  * run-as cannot reach shared storage (SELinux), so it is not used here.
