## 🎯 Problem-Solution Mapping

### Problem 1: Components Too Large (4,146 LOC over)

**Solution:** Component decomposition into 40+ smaller components

**Reference:** [COMPONENT_VIOLATION_ANALYSIS.md](./COMPONENT_VIOLATION_ANALYSIS.md)

| Component | Strategy | Result |
|-----------|----------|--------|
| GitHubActionsFetcher (887 LOC) | Extract hooks + child components | 85 LOC + 6 children |
| NerdModeIDE (733 LOC) | Split panels into components | 110 LOC + 4 children |
| LuaEditor (686 LOC) | Extract script logic | 120 LOC + 2 children |
| Others (Tier 2-3) | Tab/section decomposition | 85-100 LOC each |

**Timeline:** 2 weeks for Tier 1, 1 week for Tier 2-3

---

### Problem 2: Scattered State Management

**Solution:** Unified 4-category state framework

**Reference:** [STATE_MANAGEMENT_GUIDE.md](./STATE_MANAGEMENT_GUIDE.md)

| State Type | Pattern | Limit | Examples |
|-----------|---------|-------|----------|
| Local | useState | 2-3/component | UI toggles, form inputs |
| Global | Context | 3-4 providers | Auth, theme, notifications |
| Persistent | Prisma + useState | DB-driven | User prefs, config |
| Cache | React Query | Auto-managed | API responses, expensive queries |

**Timeline:** 2 weeks for audit + 2 weeks for migration

---

### Problem 3: Incomplete Package System

**Solution:** Asset management + import/export + pre-built packages

**Reference:** [PACKAGE_SYSTEM_COMPLETION.md](./PACKAGE_SYSTEM_COMPLETION.md)

| Feature | Status | Effort | Timeline |
|---------|--------|--------|----------|
| Asset storage & upload | 0% | 12h | Week 4-5 |
| Import/export UI | 0% | 14h | Week 5-6 |
| 5 pre-built packages | 0% | 10h | Week 6-7 |

**Timeline:** 3 weeks to complete

---

### Problem 4: Documentation Scattered (4,935+ LOC across 50+ files)

**Solution:** Consolidation + reorganization + new implementation guide

**Reference:** [PRIORITY_ACTION_PLAN.md](./PRIORITY_ACTION_PLAN.md) - Phase 4

**Deliverables:**
- Single master index
- Implementation guide (step-by-step)
- Developer playbooks
- API documentation

**Timeline:** 2 weeks for consolidation + ongoing maintenance

## 🆘 Troubleshooting & Support

### Issue: Component still >150 LOC after refactoring
**Solution:** 
1. Check COMPONENT_VIOLATION_ANALYSIS.md for your component type
2. Ensure all logic moved to hooks
3. Each child component should be single-purpose
4. Consider extracting CSS to separate file

### Issue: State management unclear
**Solution:**
1. Read STATE_MANAGEMENT_GUIDE.md decision tree
2. Ask: "Will this survive page reload?" (DB vs local)
3. Ask: "Is this needed globally?" (Context vs local)
4. When in doubt, keep local until needed globally

### Issue: Package import/export failing
**Solution:**
1. Validate package ZIP structure against spec
2. Check asset encoding (base64)
3. Verify tenantId isolation
4. Review API error logs

### Issue: Test coverage low
**Solution:**
1. Use parameterized tests (see TESTING_QUICK_REFERENCE.md)
2. Test happy path + error cases
3. Test props validation
4. Run: `npm run test:coverage:report`
