scaffolding summary helper +- Extracted `SubOption.tsx` (79 lines) - nested toggle component +- Extracted `ToggleOption.tsx` (112 lines) - main toggle with description +- **Commit:** `d1f8ba66` + +### ✅ Phase 2: Shared Sections +- Extracted `StudentNameInput.tsx` (32 lines) - text input +- Extracted `DigitRangeSection.tsx` (173 lines) - double-thumb range slider +- Extracted `OperatorSection.tsx` (129 lines) - operator selection buttons +- Extracted `ProgressiveDifficultyToggle.tsx` (91 lines) - interpolate toggle +- **Commits:** `d7d97023`, `60875bfc` + +### ✅ Phase 3: Smart Mode Controls +- Extracted `SmartModeControls.tsx` (1412 lines) - entire Smart Mode section + - Difficulty preset dropdown + - Make easier/harder buttons + - Overall difficulty slider + - 2D difficulty space visualizer with interactive SVG + - Scaffolding summary tooltips +- Removed useState dependencies from ConfigPanel +- **Commit:** `e870ef20` + +### ✅ Phase 4: Manual Mode Controls +- Extracted `ManualModeControls.tsx` (342 lines) -

Conditional borrowing notation/hints toggles +- Fixed parsing error (extra closing paren) +- **Commit:** `e12651f6` + +### ✅ Phase 5: Final Cleanup +- Removed all unused helper functions +- Removed unused state variables +- Removed debugging console.log statements +- Added missing `defaultAdditionConfig` import +- Added missing `Slider` import to ManualModeControls +- Cleaned up backup files and temp scripts +- **Commit:** `c33fa173` + +## Architecture After Refactoring + +### Final ConfigPanel.tsx (105 lines) +``` +ConfigPanel +├── Imports (11 lines) +│ ├── Panda CSS (stack pattern) +│ ├── Types (WorksheetFormState) +│ ├── Config (defaultAdditionConfig) +│ └── Child Components (6 imports) +├── Mode Switch Handler (50 lines) +│ ├── Smart mode: preserve displayRules, set profile +│ └── Manual mode: convert displayRules to boolean flags +└── JSX Render (35 lines) + ├── StudentNameInput + ├── DigitRangeSection + ├── OperatorSection + ├── ModeSelector + ├── ProgressiveDifficultyToggle + ├── SmartModeControls (conditional) + └── ManualModeControls (conditional) +``` + +### Component Directory Structure +``` +components/ +├── ConfigPanel.tsx (105 lines) -

5 small phases instead of 1 big bang +2. **Commit after each phase** - easy to roll back if needed +3. **Extract before delete** - created new files first, then removed from original +4. **Testing at each step** - caught issues early (Slider import, parsing error) + +### ⚠️ Issues Encountered +1. **Missing Slider import** (Phase 2) - removed too early, had to add back temporarily +2. **Parsing error in ManualModeControls** (Phase 4) - extra closing paren from extraction +3. **Missing Slider import again** (Phase 5) - forgot to add to ManualModeControls + +### 💡 Best Practices Established +1. **Always check imports** - verify each extracted component has all necessary imports +2. **Format after extraction** - biome catches syntax errors immediately +3. **Search for usage** - grep for function names before removing +4. **Keep backup files** - ConfigPanel.tsx.bak useful for comparison (deleted after completion) + +## Next Steps (Optional Future Improvements) + +### Consider for Future Refactoring: +1. **Extract layout helpers** - `getDefaultColsForProblemsPerPage` and `calculateDerivedState` could go in a `layoutUtils.ts` file if needed again +2. **Shared prop types** - Create `config-panel/types.ts` for common interfaces +3. **Storybook stories** - Add stories for each extracted component +4. **Unit tests** - Add tests for ToggleOption, SubOption, mode switching logic + +### Current State: Production Ready ✅ +- All phases complete +- All commits clean +- No known issues +- Zero functionality change +- 95.9% size reduction achieved + +--- + +**Refactoring completed:** 2025-11-08 +**Total commits:** 5 phases across 5 commits +**Final commit:** `c33fa173` diff --git a/apps/web/src/app/create/worksheets/addition/problemGenerator.ts b/apps/web/src/app/create/worksheets/addition/problemGenerator.ts index 40eb3f23..a4c0c153 100644 --- a/apps/web/src/app/create/worksheets/addition/problemGenerator.ts +++ b/apps/web/src/app/create/worksheets/addition/problemGenerator.ts @@ -414,9 +414,67 @@ export function generateOnesOnlyBorrow( return minDigits === 1 ?
