+# ExaMetra PRD Status Report
+
+**Date:** August 1, 2026  
+**PRD Reference:** SchoolOS Consolidated PRD (12 Modules: A-L)  
+**Current Status:** 25-30% implementation complete
+
+---
+
+## Executive Summary
+
+The project has **partial implementations** across multiple modules but lacks cohesive architecture. Today's consolidation work unified Calendar and Grading, but **10 of 12 modules require completion** to achieve PRD compliance.
+
+**Current Coverage:**
+- Module A (Academics): ~40% (competency grids, grading logic, basic assessments)
+- Module C (Communication): ~30% (basic messaging, no escalation policy engine)
+- Module D (Learning Hub): ~20% (videos/exercises exist, not fully integrated)
+- Module F (Exam Mode): ~35% (exam-proctoring view exists, not kiosk-compliant)
+- Module K (Identity): ~50% (auth exists, but not full GDPR integration)
+- **Modules B, E, G, H, I, J, L:** ~0% (missing or stub implementations)
+
+---

+
+## 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.
