 | Tests use pump()+pump(Duration) instead of pumpAndSettle() | CalendarStrip animation controllers cause pumpAndSettle timeout — fixed-duration pump steps are reliable |
 | No separate Riverpod provider for history sheet | ref.read(appDatabaseProvider) directly in ConsumerWidget — one-shot modals do not need a dedicated provider |
 | CalendarTaskRow onTap navigates to task edit form | Makes history accessible in one tap from home screen, consistent with GoRouter route patterns |
+- [Phase 07-task-sorting]: Default sort is alphabetical — continuity with existing A-Z SQL sort in CalendarDayList
+- [Phase 07-task-sorting]: overdueTasks are NOT sorted — pinned at top in existing order per design decision
+- [Phase 07-task-sorting]: Sort preference stored as enum.name string in SharedPreferences (not intEnum) — enum reordering safe
