ARCHITECTURE.md still said every non-silent ringtone_uri is a content URI and listed the picker's rows without the bundled "Timer expired" sound, so a reader could Uri.parse the clockula://tone/ sentinel directly. It now names the sentinel, BundledTones as its only resolver, and where the tone sits in the picker.
A view-model test now covers a device whose only listed tone is the bundled one, which must still show the "no alarm sounds" banner. The existing test only checked an empty list, so it passed even if the bundled tone were counted as a device sound.
