SchulOS PRD Status Report

Date: August 1, 2026 PRD Reference: SchulOS 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

• Consolidate Calendar (done today)
• 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

SchulOS 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.
