 - [Phase 10-dead-code-cleanup]: TaskWithRoom retained in daily_plan_models.dart — actively used by calendar_dao.dart, calendar_providers.dart, and related calendar files
 - [Phase 11-issue-3-tasks-management-allow-task-checking-anytime-and-pre-populate-recurring-tasks]: D-01: Remove isFuture/canComplete restrictions — checkboxes always enabled across all UI; calendar_task_row.dart unchanged (caller was applying restriction)
 - [Phase 11-issue-3-tasks-management-allow-task-checking-anytime-and-pre-populate-recurring-tasks]: D-02: When completing on non-due day, use today as baseDate for nextDueDate calculation (todayStart == taskDueDay pattern)
+- [Phase 11-issue-3-tasks-management-allow-task-checking-anytime-and-pre-populate-recurring-tasks]: D-03: Pre-population via query-time virtual instances — no schema migration
