## Next Steps

### Immediate
- ✅ **Commit to feature branch**: DONE (commit `4ffde78`)
- 📋 **Ready for merge to main**: Pending Week 4 completion

### Week 4 (Next)
1. **Day 8**: PHP language support implementation
2. **Day 9**: Ruby language support implementation
3. **Day 10**: Swift language support implementation

### Week 5+ (Future)
- CLI/MCP integration enhancements
- Performance optimization
- Incremental indexing

---

## Risk Assessment

### Risks Identified: **NONE**

**Why Low Risk**:
1. ✅ All tests passing (100% pass rate)
2. ✅ No regressions (all 301 tests still passing)
3. ✅ High code coverage (91%)
4. ✅ Quality checks passing (mypy, ruff)
5. ✅ Feature branch (not main)
6. ✅ Comprehensive testing (32 C# tests)
7. ✅ Documentation complete

**Mitigation**:
- Feature branch allows safe testing before main merge
- Comprehensive test suite catches issues early
- Rollback possible via git revert if needed

---

## Success Criteria

All criteria met:

- [x] **Functionality**: C# symbol extraction works correctly
- [x] **Quality**: 91% coverage, mypy strict, ruff compliant
- [x] **Performance**: <3s for 301 tests
- [x] **Testing**: 32 tests, 100% pass rate
- [x] **Documentation**: Complete and accurate
- [x] **Integration**: Dispatcher works with 8 languages
- [x] **No Regressions**: All existing tests still pass

**Overall**: ✅ **ALL SUCCESS CRITERIA MET**

---

## Lessons Learned

### What Went Well
1. ✅ **Comprehensive review process** identified 7 additional test gaps
2. ✅ **Quality-first approach** ensured all checks passed before commit
3. ✅ **Detailed documentation** makes code maintainable
4. ✅ **Consistent patterns** with Java/C++ made implementation smooth

### Process Improvements
1. ✅ **Added parser tests early** (not just extractor tests)
2. ✅ **Compared with similar languages** (Java) to find gaps
3. ✅ **Created quality review document** for transparency
4. ✅ **Staged files systematically** (impl → tests → docs)

### Time Efficiency
- **Initial estimate**: 2-3 hours
- **Actual time**: ~3.5 hours (including review improvements)
- **Extra time**: +0.5-1.5 hours for quality improvements
- **Result**: Worth it for comprehensive coverage
