+<objective>
+Delete three orphaned v1.0 daily plan presentation files and clean up the orphaned DailyPlanState class from the domain models file, then verify no regressions.
+
+Purpose: These files were superseded by the calendar strip (Phase 5, v1.1) but never removed. Cleaning them prevents confusion and reduces maintenance surface.
+Output: Three files deleted, one file trimmed, zero test/analysis regressions.

+    1. Delete these three files entirely (use `rm` or equivalent):
+       - lib/features/home/presentation/daily_plan_providers.dart
+       - lib/features/home/presentation/daily_plan_task_row.dart
+       - lib/features/home/presentation/progress_card.dart
+
+    2. Edit lib/features/home/domain/daily_plan_models.dart:
+       - Remove the DailyPlanState class (lines 16-31) entirely. It is only used by the now-deleted daily_plan_providers.dart.
+       - Keep the TaskWithRoom class intact — it is used by calendar_dao.dart, calendar_models.dart, calendar_providers.dart, calendar_day_list.dart, calendar_task_row.dart, and daily_plan_dao.dart.
+       - Keep the existing import of database.dart at line 1.
+
+    3. DO NOT touch these files (they are still in use):
+       - lib/features/home/data/daily_plan_dao.dart (used by database.dart daos list and settings_screen.dart)
+       - lib/features/home/data/daily_plan_dao.g.dart (generated, paired with DAO)

+    1. Run `dart analyze` from the project root. Must report "No issues found!" with zero errors, warnings, or infos. If any issues appear related to the deleted files (unused imports, missing references), fix them — but based on codebase analysis, none are expected since the three files have zero importers.
+
+    2. Run `flutter test` from the project root. All 144 tests must pass. No test references the deleted files or DailyPlanState (confirmed via grep during planning).
+
+    3. If dart analyze reveals any issue (unexpected import of deleted file elsewhere), fix the import. This is a safety net — grep during planning found zero references, but the analyzer is authoritative.
