✅ Demo Complete!

🎯 MIESC v3.5.0 Capabilities Demonstrated:
   1. ✅ Multi-adapter system (20 security tools)
   2. ✅ Layer 1 static analysis (Slither)
   3. ✅ OpenLLaMA AI enhancement (sovereign LLM)
   4. ✅ DPGA compliance (100% optional tools)
   5. ✅ Comprehensive vulnerability detection

🔬 Vulnerabilities Detected in VulnerableBank.sol:
   • Reentrancy in withdraw() function
   • Missing access control in emergencyWithdraw()
   • Dangerous tx.origin usage in transferOwnership()
   • Potential for complete fund drain

🚀 Next Steps:
   1. Run full analysis: python xaudit.py --target demo_contracts/VulnerableBank.sol
   2. Install Ollama for AI enhancement: https://ollama.com
   3. Explore other layers: symbolic execution, formal verification
   4. Generate compliance reports: --output report.html
