# Phase 10 Plan 01: Dead Code Cleanup Summary

**Deleted three orphaned v1.0 daily plan presentation files and stripped DailyPlanState from domain models, leaving TaskWithRoom intact for the calendar system — zero test/analysis regressions across all 144 tests.**

## Performance

- **Duration:** ~5 min
- **Started:** 2026-03-19T00:00:54Z
- **Completed:** 2026-03-19T00:05:00Z
- **Tasks:** 2
- **Files modified:** 4 (3 deleted, 1 trimmed)

## Accomplishments

- Deleted `daily_plan_providers.dart`, `daily_plan_task_row.dart`, and `progress_card.dart` — all orphaned since Phase 5 replaced the daily plan UI with the calendar strip
- Removed `DailyPlanState` class from `daily_plan_models.dart` (it was only referenced by the now-deleted providers file)
- Preserved `TaskWithRoom` in `daily_plan_models.dart` — confirmed it remains importable by calendar system files
- `dart analyze` reports zero issues; all 144 tests pass with no regressions

## Task Commits

Each task was committed atomically:

1. **Task 1: Delete orphaned files and remove DailyPlanState** - `510529a` (chore)
2. **Task 2: Verify zero regressions** - verification only, no file changes

**Plan metadata:** `80e7011` (docs: complete dead-code-cleanup plan)

## Files Created/Modified

- `lib/features/home/domain/daily_plan_models.dart` - Removed DailyPlanState class (lines 16-31); TaskWithRoom preserved
- `lib/features/home/presentation/daily_plan_providers.dart` - DELETED (orphaned v1.0 file)
- `lib/features/home/presentation/daily_plan_task_row.dart` - DELETED (orphaned v1.0 file)
- `lib/features/home/presentation/progress_card.dart` - DELETED (orphaned v1.0 file)

## Decisions Made

- DailyPlanDao was NOT removed from `database.dart` — it is still registered in the `@DriftDatabase` annotation and used by `settings_screen.dart`. Only the presentation layer files were deleted.
- TaskWithRoom was kept because it is imported by: `calendar_dao.dart`, `calendar_providers.dart`, `calendar_models.dart`, `calendar_day_list.dart`, `calendar_task_row.dart`, and `daily_plan_dao.dart`.

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

None.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness

- Phase 10 dead code cleanup complete
- No blockers — dead code that was tracked as a blocker in STATE.md is now resolved
