# lib/services_apps.sh — per-application blocking checks (messaging-app launch
# wrappers, and the LeechBlock browser extension for the invoking user).
#
# Sourced by check_and_enable_services.sh.

# Absolute paths the checks below probe are prefixed with $SYSROOT, which is
# empty in production and a fixture tree under test. It is deliberately NOT
# defaulted here: several repairs in this family write outside `run` (chattr,
# find -delete, an append to resolved.conf), so a test that forgot to set it
# would edit the real /etc. Unset is a hard error; empty is the real filesystem.
