Plan referenced `themeNotifierProvider` based on older convention. All code uses the correct generated name. ## Deviations from Plan ### Auto-fixed Issues **1. [Rule 1 - Bug] Used themeProvider instead of themeNotifierProvider** - **Found during:** Task 1 (settings screen and app shell test) - **Issue:** Plan referenced `themeNotifierProvider` but Riverpod 3 code generation produces `themeProvider` - **Fix:** Used correct generated name `themeProvider` throughout all new code - **Files modified:** lib/features/settings/presentation/settings_screen.dart, lib/app.dart, test/shell/app_shell_test.dart - **Verification:** dart analyze passes cleanly, all tests pass - **Committed in:** f2dd737 and 014722a (Task 1 and Task 2 commits) --- **Total deviations:** 1 auto-fixed (1 bug -- naming convention) **Impact on plan:** Trivial naming difference. No scope creep. ## Issues Encountered None ## User Setup Required None - no external service configuration required. ## Next Phase Readiness - Phase 1 complete: app launches with full 3-tab navigation, theme switching, and localization - Drift database ready to receive Room and Task tables in Phase 2 - Rooms screen placeholder ready to be replaced with room list + CRUD in Phase 2 - Home screen placeholder ready to be replaced with daily plan view in Phase 3 - Settings screen pattern established for adding notification settings in Phase 4 - All 16 tests passing (database, theme, color scheme, localization, app shell) ## Self-Check: PASSED - All 8 key files verified present on disk - Both task commits verified in git log (f2dd737, 014722a) - Task 3 was checkpoint (auto-approved, no code changes) --- *Phase: 01-foundation* *Completed: 2026-03-15*
