Hello. Changes since the last review, addressing prior feedback: - Brightness control uses D-Bus wherever GNOME provides an interface: Mutter's backlight API on GNOME 49+, and org.gnome.SettingsDaemon.Power on 45-48 for the built-in display. The ddcutil binary is spawned (async Gio.Subprocess only, never sync) solely for external DDC/CI monitors on shell versions where no D-Bus alternative exists. Monitor detection ("ddcutil detect") also runs async, in the prefs process, not the shell. - Prefs-only modules moved to a prefs/ folder for review clarity. - Routine logging is now gated behind a "debug-logging" setting (off by default); only genuine errors are logged unconditionally. The package passes shexli with 0 findings. - gschemas.compiled is not included; solar times are computed locally (suncalc), so the extension makes no network requests — only the prefs dialog contacts ipinfo.io/openstreetmap.org for optional location detection, as stated in the description.
