Reminders never fired for a calendar hidden at system level and nothing hinted
at it: the provider only schedules reminder alarms for Calendars.VISIBLE=1,
while Calendula filtered with its own disabledCalendarIds pref and parsed
isVisibleInSystem without ever using it — two models that could disagree
indefinitely.
Settings → Calendars now writes Calendars.VISIBLE, one calendar per update
(CalendarProvider2 skips its own checkNextAlarm() reschedule for any selection
that isn't _id=), and every display predicate reads isVisibleInSystem. The
drawer's filter sheet stays a purely in-app declutter and still leaves reminders
alone.
With VISIBLE=0 the provider creates no alert rows, so there is nothing left to
suppress: the disabled-calendar gates, SuppressedReminderStore and the re-enable
recovery are gone. A one-shot migration reconciles the retired set with the app's
state winning — enabled in-app and syncing gets shown, disabled gets hidden,
everything else untouched — so the upgrade changes nothing the user sees.
