Enhanced Medical RAG System - Production Ready (Cerebras Powered)
VedaMD Medical RAG - Production Integration

This system integrates our Phase 2 medical enhancements with Cerebras Inference API:
1. Enhanced Medical Context Preparation (Task 2.1) ✅
2. Medical Response Verification Layer (Task 2.2) ✅
3. Compatible Vector Store with Clinical ModernBERT enhancement ✅
4. Cerebras API with Llama 3.3-70B for ultra-fast medical-grade generation
5. 100% source traceability and context adherence validation

PRODUCTION MEDICAL SAFETY ARCHITECTURE:
Query → Enhanced Context → Cerebras/Llama3.3-70B → Medical Verification → Safe Response

CRITICAL SAFETY GUARANTEES:
- Every medical fact traceable to provided Sri Lankan guidelines
- Comprehensive medical claim verification before response delivery
- Safety warnings for unverified medical information
- Medical-grade regulatory compliance protocols
