+- [ ] API standardlaştırma
+- [ ] **Modül A tamamlama** (Academics Core)
+- [ ] **Modül K tamamlama** (Identity)
+
+### Hafta 3-5: Çekirdek Modüller (MUST DO)
+- [ ] **Modül C: Escalation Engine** (Veli/Öğrenci yönetim kurulu)
+- [ ] **Modül F: Sınav Modu Lockdown**
+- [ ] **Modül H: Bildirim Hub**
+- [ ] **Modül L: GDPR Uyum** ← ZORUNLU
+
+### Hafta 6-8: Ek Modüller (İsteğe Bağlı)
+- [ ] Modül B (Signage)
+- [ ] Modül D (Learning Hub)
+- [ ] Modül E (AI Tutor)
+- [ ] Modül G (Digital Notebook)
+- [ ] Modül J (Dashboard)
+
+---
+
+## Aciliyet
+
+| Modül | Aciliyet | Neden |
+|-------|----------|-------|
+| **L** | 🔴 KRİTİK | ALMANYA'DA DAĞITIM YASAL ÖN KOŞUL |
+| **A** | 🔴 KRİTİK | Tüm akademik işler buna dayanır |
+| **F** | 🔴 KRİTİK | Sınav modu olmadan kullanılamaz |
+| **K** | 🔴 KRİTİK | Kimlik ve izin sistemi lazım |
+| **C** | 🟡 YÜKSEK | Veli iletişimi temel özellik |
+| **H** | 🟡 YÜKSEK | Bildirimleri merkezi olmadan başarısız |
+| **I** | 🟡 YÜKSEK | (Bugün tamamlandı, tamamlamayı gerekli) |
+| B,D,E,G,J | 🟢 DÜŞÜK | Güzel-to-have, core olmayan |
+
+---
+
+## Sonuç
+
+**Nerede:** 30% tamamlı, çok dağınık  
+**Eksikler:** 10 modül, 39 DB tablosu, 200+ API rotası  
+**Neden önemli:** Almanya'daki hukuki uyum zorunlu (GDPR/DSGVO)
+
+**İlk yapılacak:**
+1. Modül L tamamla (GDPR uyum) — Hukuki ön koşul
+2. Modül A tamamla (Academics)
+3. Modül C yapı (Escalation)
+4. Modül F yapı (Exam Lockdown)
+
+Sonra Modülleri B, D, E, G, J yapabilir.

+
+## Architecture Issues
+
+### 1. Missing API Standardization
+- 264 API routes with inconsistent response formats
+- No centralized error handling
+- No request validation middleware
+- No audit logging middleware
+
+**Fix:** Create `src/lib/api-response.ts` + middleware stack
+
+### 2. Duplicate Fetching Logic
+- 160+ duplicate fetch patterns using useEffect
+- No caching/deduplication
+
+**Fix:** Universal `useApi()` hook (already planned, needs completion)
+
+### 3. No Module Isolation
+- Components reach across module boundaries
+- Shared state management not centralized
+- Tight coupling between modules
+
+**Fix:** Enforce module APIs, move to facade pattern
+
+### 4. Database Schema Gaps
+- Missing 15+ tables required by PRD
+- No enforcement of soft deletes
+- No audit trail on sensitive changes
+- No data classification column
+
+**Fix:** Complete Prisma schema, add migrations
+
+---
+
+## Critical Path to PRD Compliance
+
+### Phase 1: Foundation (Weeks 1-2) — Must Complete
+- [x] Consolidate Calendar (done today)
+- [x] Consolidate Grading (done today)
+- [ ] Standardize API responses
+- [ ] Build useApi hook
+- [ ] Complete Module A (Academics)
+- [ ] Complete Module K (Identity)
+
+**Blocking:** Everything else depends on solid foundation
+
+### Phase 2: Core Modules (Weeks 3-5) — Must Complete
+- [ ] Module C (Escalation engine — requires Module I calendar)
+- [ ] Module F (Exam Mode lockdown)
+- [ ] Module H (Notifications hub)
+- [ ] Module L (GDPR compliance engine)
+
+**Blocking:** Legal go-live
+
+### Phase 3: Extended Modules (Weeks 6-8) — Nice-to-Have
+- [ ] Module B (Signage)
+- [ ] Module D (Learning Hub)
+- [ ] Module E (AI Tutor)
+- [ ] Module G (Digital Notebook)
+- [ ] Module J (Dashboard Widgets)
+

+## Code Metrics
+
+| Metric | Current | Target | Gap |
+|--------|---------|--------|-----|
+| Components | 72 | 45 | Consolidate 27 |
+| API Routes | 264 | 80 | Reduce 184 |
+| LOC (total) | ~200K | ~140K | Remove 60K |
+| Test Coverage | <50% | 70% | Add 2000+ tests |
+| Module Completeness | 30% | 100% | Build 70% |
+
+---
+
+## Immediate Next Steps (This Week)
+
+1. **Review and Test** today's consolidation (calendar + grading)
+2. **Create API standardization** layer
+3. **Complete Module A** (Academics) — add missing DB tables, complete report PDF
+4. **Start Module L** (Legal/GDPR) — non-negotiable for German school deployment
+5. **Add 12 missing DB tables** and migrations
+
+---
+
+## Risk Assessment
+
+| Risk | Severity | Mitigation |
+|------|----------|-----------|
+| PRD too large | HIGH | Use phase approach, prioritize Modules A, C, F, K, L first |
+| GDPR non-compliance (Module L) | CRITICAL | Start Module L week 1, not week 8 |
+| Browser lockdown impossible | MEDIUM | Use Electron or Kiosk.js if Web API insufficient |
+| SQLite outgrown | LOW | Keep ORM abstract, upgrade path to Postgres ready |
+| Missing data model | HIGH | Complete all 50 DB tables before coding UI |
+
+---
+
+## Conclusion
+
+ExaMetra is **30% complete** against the 12-module PRD. Today's consolidation work (Calendar + Grading) was critical infrastructure. To reach **100% PRD compliance in 8 weeks**, the team must:
+
+1. Complete Module A (Academics Core) — foundation for all others
+2. Build Module L (GDPR compliance) in parallel — non-negotiable
+3. Implement Modules C, F, H in weeks 3-5
+4. Defer Modules B, D, E, G, J to weeks 6-8 if resources tight
+
+**Critical blocker:** Module L must be complete before go-live at any German school.

+## Missing Database Tables (39 Required)
+
+### Priority 1: Add This Week
+```
+Module L (GDPR):
+[ ] DataRetentionPolicy
+[ ] ConsentRecord  
+[ ] AccessLog
+[ ] DataExportRequest
+[ ] BreachNotification
+
+Module A (Academics):
+[ ] MasteryLevelDefinition
+[ ] ClassCompetencyAssignment
+```
+
+### Priority 2: Add Week 2
+```
+Module C (Communication):
+[ ] EscalationPolicy
+[ ] EscalationRequest
+[ ] ClassMessagingLock
+
+Module H (Notifications):
+[ ] Notification
+[ ] NotificationTemplate
+[ ] NotificationDeliveryLog
+
+Module I (Calendar):
+[ ] SchoolCalendar
+[ ] ClassPeriod
+[ ] RecurrencePattern
+```
+
+### Priority 3: Add Week 3-4
+```
+Remaining 22 tables for Modules B, D, E, F, G, J
+```

+
+## Code Quality Metrics
+
+### Current State
+```
+Components:        72 (HIGH DUPLICATION)
+API Routes:        264 (INCONSISTENT)
+LOC Total:         ~200K
+Test Coverage:     <50%
+Bundle Size:       ~2.5MB
+```
+
+### Target State (Week 8)
+```
+Components:        45 (consolidated)
+API Routes:        80 (standardized)
+LOC Total:         ~140K
+Test Coverage:     70%+
+Bundle Size:       ~1.8MB
+```
+
+### Reductions Needed
+```
+Components:        -27 (consolidate)
+API Routes:        -184 (standardize)
+LOC:               -60K (remove duplication)
+Add Tests:         +2000 (increase coverage)
+```

+## Risk Tracking
+
+| Risk | Impact | Mitigation | Status |
+|------|--------|-----------|--------|
+| **Module L not ready for German law** | 🔴 CRITICAL | Start Week 1, hire legal consultant | ⚠️ At Risk |
+| **Browser lockdown impossible** | 🟡 HIGH | Research Electron/Kiosk.js alternatives | ✅ Planned |
+| **Database schema incomplete** | 🟡 HIGH | Add all 39 tables Week 1-2 | ⚠️ In Progress |
+| **API inconsistency** | 🟡 HIGH | Standardize responses + middleware | 🚀 Starting |
+| **Test coverage <5%** | 🟡 HIGH | Add 2000+ tests in parallel | ✅ Planned |
+
+---
+
+## Success Criteria (Week 8 Deliverable)
+
+- [x] 12 modules defined
+- [ ] 100% module feature parity with PRD
+- [ ] All 39+ DB tables implemented
+- [ ] 264 API routes standardized
+- [ ] 70%+ test coverage
+- [ ] Module L (GDPR) production-ready
+- [ ] Zero hardcoded values (all DB-driven)
+- [ ] Soft deletes + audit trail
+- [ ] DPIA gating functional
+- [ ] Self-hosting Docker image ready
+
+---
+
+## Deployment Timeline
+
+```
+Week 1-3:  Stabilize Foundation + Legal (Module L)
+Week 4-6:  Implement Core Features (Modules A-H, K)
+Week 7-8:  Polish, Test, Document, Deploy
+Week 9:    Go-Live to Real School
+```
+
+---
+
+## Notes
+
+1. **Module L (GDPR) is non-negotiable** — German schools cannot use without it
+2. **Database first** — Define all tables before UI code
+3. **No hardcoding** — All rules, thresholds, templates must be DB-driven
+4. **Tests early** — Each module needs tests, not afterthought
+5. **Self-hosting path** — Docker + SQLite + local storage must work
