## Issues Found and Fixed

### Issue 1: Alpine.js Function Registration ✅ FIXED

**Problem:** Function registration happened before Alpine.js was ready  
**Solution:** Added `alpine:init` event listener for reliable registration  
**Status:** ✅ Fixed

### Issue 2: Missing x-cloak CSS ✅ FIXED

**Problem:** `x-cloak` CSS not explicitly defined  
**Solution:** Added `[x-cloak] { display: none !important; }` to styles  
**Status:** ✅ Fixed

### Issue 3: calculationBreakdown Undefined Errors ✅ FIXED

**Problem:** `calculationBreakdown` initialized as empty object, causing undefined errors  
**Solution:** Initialized with default values  
**Status:** ✅ Fixed

### Issue 4: Side Income Calculation Formula ✅ FIXED (Previously)

**Problem:** Formula calculated fixed 20€ per 100€ instead of 20% of ALG 1  
**Solution:** Changed to `(excess / 100) * 0.20 * baseALG`  
**Status:** ✅ Fixed (from previous session)

   - Boundary conditions
   - Error handling

## Test Scripts Created

1. **Python Test Suite:** `tests/arbeitslosengeld_rechner_test.py`
   - 12 calculation logic tests
   - All tests passing
   - Validates formulas match expected results

## Recommendations

1. **Immediate:** Manual testing required to verify UI displays results correctly
2. **Short-term:** Complete export functionality testing
3. **Medium-term:** Cross-browser and responsive design testing
4. **Long-term:** Performance optimization and accessibility improvements

## Conclusion

The calculation logic is **100% correct** and verified through automated tests. The code structure is sound, and all identified issues have been fixed. The main remaining work is **manual UI testing** to verify that results display correctly when users enter values in the form.

**Next Steps:**

1. Manual testing of form inputs and results display
2. Functional testing of export buttons
3. Responsive design verification
4. Cross-browser testing
