- TimeGridView: remember Instant.now() (keyed on the day) and the day-header
DateTimeFormatter instead of rebuilding both on every recomposition/frame —
fixes flicker in the past-event dimming and avoids repeated allocation.
- CalendarViewModel.refreshFromCache: short-circuit the non-group filter pass
when both hiddenKeys and banishedKeys are empty, mirroring the existing
group-mode short-circuit.
- CalendarViewModel.setCalendarHiddenSynced: wrap the server PATCH in
runCatching and surface failures via state.error instead of silently
dropping them (the local toggle would otherwise diverge from the server
unnoticed).
- CalendarViewModel.afterMutation: refetch only the already-cached range
(force-bypassing loadRange's cache check) instead of invalidateCache() +
initialLoad(), which reloaded the entire ±cacheMonths window and froze the
UI on every single event save.
- CalendarrRoot: replace calendarVm!! with a null-safe ?.let, falling back to
the splash screen instead of crashing if the VM isn't ready yet.
- GroupsScreen: replace existing!!.icon!! / g.icon!! double force-unwraps
with safe-call chains (existing?.icon?.takeIf { GroupIcons.isKey(it) }).
Deliberately out of scope: R8/minify settings, MonthView's cache window
size (MONTHS_BACK/MONTHS_AHEAD), and mergeIntoCache's merge logic (already
reviewed as correct). No debounce added to setCalendarHiddenSynced — would
need new machinery beyond this fix's scope.
