-## Post-MVP Priorities
+## Technical Debt & Prioritization Roadmap
 
-### Immediate Next Steps (Q1 2026)
+Based on comprehensive codebase audit (January 2026), MetaBuilder has **well-managed technical debt** with a clear refactoring path to increase data-driven architecture from 27% to 35-40%.
 
-**1. Backend API Integration** ⭐ HIGHEST PRIORITY
-- Connect placeholder API client to real endpoints
-- Implement entity CRUD endpoints
-- Add authentication middleware
-- Request/response validation
-- Error handling
+### Executive Summary
 
-**Why:** Without real API integration, CRUD operations are non-functional
+**Current State**:
+- 2,047 total files
+- 73% TypeScript (1,487 files) - Infrastructure + UI
+- 27% JSON/YAML (560 files) - Schemas + packages + seed data
+- **Goal**: 35-40% JSON/YAML (data-driven) through strategic cleanup
 
-**2. Enhanced CRUD UX** ⭐ HIGH PRIORITY
-- RenderComponent integration for forms
-- Client-side validation
-- Pagination for lists
-- Search/filter UI
+**Total Estimated Effort**: 9-16 hours of refactoring
+**Recommended Timeline**: Phase 1 (1-2 weeks) + Phase 2 (4-6 weeks)
 
-**Why:** Current UI is functional but bare-bones; needs polish for real users
+### Phase 1: Critical Cleanup (1-2 weeks, ~2-3 hours)
 
-**3. God Panel Foundation** ⭐ MEDIUM PRIORITY
-- Route management UI
-- Package installation UI
-- Basic user management
+**🔴 P0 - Block Production Issues** (None identified - codebase is stable)
 
-**Why:** Enables non-technical users to configure the system
+**🟠 P1 - Quick Wins, High Impact**
 
-### Technical Debt
+| # | Task | Effort | Impact | Files | Status |
+|---|------|--------|--------|-------|--------|
+| **1.1** | **Delete `/old` directory** | 1h | High | 119 | ❌ TODO |
+| | Pre-Next.js SPA implementation | | | | |
+| | Contains Vite, React, Radix UI | | | | |
+| | Completely superseded by NextJS | | | | |
+| **1.2** | **Delete `.backup` files** | 10m | Low | 4 | ❌ TODO |
+| | Not needed with Git history | | | | |
+| | Files: `*.backup` in `/dbal/development/` | | | | |
+| **1.3** | **Verify experimental code** | 1h | Low | 1 | ❌ TODO |
+| | `/css/categories/experimental.ts` | | | | |
+| | Check usage, delete if unused | | | | |
 
-**Low Priority:**
-- [ ] Replace placeholder API implementations with real calls
-- [ ] Add comprehensive error boundaries
-- [ ] Improve TypeScript type coverage
-- [ ] Add performance monitoring
-- [ ] Optimize bundle size
+**P1 Deliverables**: Remove 124 files of dead code, reduce confusion
 
-**Medium Priority:**
-- [ ] Fix 4 failing tests (pre-existing, unrelated to MVP)
-- [ ] Add E2E tests for new MVP features
-- [ ] Document API contracts
-- [ ] Add developer setup guide
+### Phase 2: Architecture Refactoring (4-6 weeks, ~9-16 hours)
 
-**High Priority:**
-- [ ] None currently
+**🟡 P2 - Medium Priority, Medium Effort**

+| # | Task | Effort | Impact | Type | Status |
+|---|------|--------|--------|------|--------|

-## Long-Term Vision
+**P2 Deliverables**: Reach 35-40% data-driven architecture, eliminate 3 sources of hardcoded data
 
-### Year 1 (2026)
-- ✅ MVP with core features
-- 🎯 Production-ready CRUD operations
-- 🎯 God panel for system configuration
+### Phase 3: Polish & Optimization (Future, 2-3 hours)
+
+**🟢 P3 - Low Priority, Low Effort**
+
+| # | Task | Effort | Impact | Type | Status |
+|---|------|--------|--------|------|--------|
+| **3.1** | **Complete TODO items** | Varies | Low | Code Quality | ❌ TODO |
+| | Compiler implementation (`/lib/compiler/index.ts`) | | | | |
+| | Review `/docs/TODO_MVP_IMPLEMENTATION.md` | 1h | | | |
+| **3.2** | **Add error boundaries** | 2h | Low | UX | ❌ TODO |
+| | Comprehensive React error boundaries | | | | |
+| **3.3** | **Improve TypeScript coverage** | 2-3h | Low | Type Safety | ❌ TODO |
+| | Strict mode compliance, eliminate `any` types | | | | |
+
+### Implementation Timeline
+
+```
+Week 1 (P1 - Quick Wins)
+├── Day 1-2: Delete /old and backups (1.5h)
+└── Day 3-5: Verify experimental code (1h)
+
+Week 2-6 (P2 - Architecture Refactoring)
+├── Week 2: Migrate seed data to YAML (2.1) - 4-5h
+├── Week 3: Eliminate adapter duplication (2.2) - 2-3h
+├── Week 4: Migrate roles to DB (2.3) - 2-3h
+├── Week 5: Migrate environment config (2.4) - 2-3h
+└── Week 6: Integration testing & validation
+
+Ongoing (P3 - Polish)
+└── As time permits after P1 + P2
+```
+
+### Dependencies & Blocking Issues
+
+**No blockers identified** - All work is independent and can be started immediately.
+
+**Recommended Sequence**:
+1. **Start P1 immediately** (delete old code) - quick win, high clarity
+2. **Start P2.1 next** (seed data) - foundation for other refactoring
+3. **Parallel P2.2, P2.3, P2.4** - Can work in parallel after P2.1
+
+### Success Metrics
+
+| Metric | Current | Target | Timeline |
+|--------|---------|--------|----------|
+| **Data-Driven Ratio** | 27% JSON/YAML | 35-40% | After P2 |
+| **Hardcoded Data** | 3 sources | 0 sources | After P2 |
+| **Deprecated Code** | 119 files | 0 files | After P1 |
+| **Adapter Duplication** | 355 lines | 0 lines | After P2.2 |
+| **Code Clarity** | 73% TS overhead | 60-65% TS | After P2 |
+
+### Risk Assessment
+
+**Low Risk**: All refactoring is backward compatible
+- Git history preserved
+- No production impact (development artifacts only)
+- All changes are additive to data-driven architecture
+- Can be tested incrementally with E2E tests
+
+**Testing Plan**:
+1. Verify all existing tests pass after each phase
+2. Run E2E tests to ensure no functionality lost
+3. Manual testing of seed data loading
+4. Verification of role/permission system after 2.3
+5. Environment config testing after 2.4
+
+### Post-Refactoring Priorities
