+- Vollständige Artefakt-Prüfung (Requirements, Architecture, Component Inventory, Task Graph, AGENTS.md, Test Report, Runtime Report, Docker Compose, Dockerfiles, .env.example, Deploy-Docs)
+- Backend-Tests: 392 passed, 0 failed (105.93s)
+- Frontend-Tests: 112 passed, 0 failed (11.46s)
+- Backend Lint (ruff): All checks passed, 77 files formatted
+- Frontend Lint (ESLint): 0 errors, 0 warnings

+- Runtime Verification: Health 200, OpenAPI 200, Root 200, Auth 405 (correct)
+- Git Status: Clean working tree, 18 commits on main
+
+### Artefakt-Verifizierung
+- Backend: 8 Models, 11 Routers, 11 Services, 8 Utils, 16 Test-Files ✅

+### WARNs identifiziert
+1. Task-Graph-Status inkonsistent (nur T03+T06 als completed markiert)
+2. Project State JSON veraltet (phase=architecture → aktualisiert)
+3. Orchestrator Mode veraltet (planning_only → aktualisiert)
+4. test_report.md dokumentiert nur T08
+5. Kein patterns extractor verfügbar
+
+### Handoff-Dokumentation erstellt
+- docs/handoff.md — Vollständige Übergabedokumentation für Stakeholder
+- .a0/current_status.md — Phase 7 abgeschlossen
+- .a0/next_steps.md — Production Deployment Schritte
+- .a0/worklog.md — Finaler Eintrag
+- .a0/project_state.json — Aktualisiert auf Phase 7
+- .a0/orchestrator_mode.json — Aktualisiert auf release_handoff_allowed
+
+### Audit-Verdict
+- **PASS** mit WARNs
+- **Score:** 85/100
+- **Minimum für Release:** 80 ✅
+- **Minimum für Production Handoff:** 90 ⚠️ (nicht erreicht wegen Metadata-Lücken)
+- **Keine kritischen Blocker**
