+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 2 - Missing Critical] Added TypeScript type definitions for all new features**
+- **Found during:** Task 1 (Navigation Controls)
+- **Issue:** Missing type definitions for new functionality
+- **Fix:** Added proper TypeScript interfaces and updated existing types
+- **Files modified:** src/types/task.ts, src/components/TaskCard.tsx
+- **Verification:** TypeScript compilation passes with no errors
+- **Commit:** 7b3a4d5
+
+**2. [Rule 3 - Blocking] Fixed drag-and-drop implementation**
+- **Found during:** Task 3 (Drag-and-Drop)
+- **Issue:** HTML5 drag and drop wasn't working properly with React
+- **Fix:** Added proper event handlers and data transfer handling
+- **Files modified:** src/components/TaskCard.tsx, src/components/CalendarGrid.tsx
+- **Verification:** Tasks can be dragged between days and reorganized
+- **Commit:** f2d8e1a
+
+---
+**Total deviations:** 2 auto-fixed (1 missing critical, 1 blocking)
+**Impact on plan:** Both fixes were necessary for correct implementation. No scope creep.
+
+## Issues Encountered
+
+- Initial drag-and-drop implementation was difficult to get working properly with React
+- Needed careful attention to event handling in drag operations
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+All UI navigation and drag-and-drop features are implemented. Ready for integration with advanced features from the next phase.
