%description
Installs a separately packaged Caihong kernel payload into the currently
running Android A/B slot. The updater detects the root PARTLABEL, writes only
the matching boot partition and reads it back for verification. It is exposed
as an explicit systemd service; the RPM transaction never writes raw block
devices. SELinux policy is intentionally deferred until permissive-mode AVC
collection is complete.
