+## What Makes This YC-Level
+
+1. **Real AI Pipeline** — 6-8 LangGraph agents with OR-Tools optimization (not mock data)
+2. **Fairness Metrics** — Gini coefficient computed per run, tracked over time
+3. **SDG Alignment** — SDG 8 (Decent Work), SDG 10 (Inequality), SDG 13 (Climate)
+4. **Production Architecture** — API gateway + microservice brain + SSE streaming
+5. **Explainability** — Every allocation decision has a human-readable explanation
+6. **Driver Wellness** — Fatigue scoring, recovery days, night safety for women
+7. **EV-First Routing** — Prioritizes electric vehicles for city-centre routes
+8. **Learning Agent** — Multi-armed bandit tunes fairness thresholds over time
+9. **LoRRI Integration** — Single API call from existing TMS, zero disruption
+10. **Scale** — K-Means + OR-Tools handles 1000+ packages in <5s
