# CellGuard supervisor — keeps the enforcement (ratlock) and detection
# (cgdetect) daemons alive and respawns either one if it dies, so a crash,
# a one-off OOM, or an accidental kill self-heals within ~30s instead of
# leaving the guard down until the next reboot.
#
# Started once by service.sh at boot. Respawned daemons are launched with
# setsid so they reparent to init (ppid=1) and survive this supervisor and
# any adb/su session. pgrep uses short script-name patterns — this script's
# own cmdline is "sh .../cgwatch.sh", so it never self-matches ratlock/cgdetect.
