❌ Known Issues & Limitations

⚠️ Partially Working Features

• Yield Farming: Core structure exists but specific DeFi protocol integrations incomplete
• Governance System: Basic proposal system works, but voting mechanism needs refinement
• DeFi Protocol Integration: Framework ready but limited to basic implementations

🐛 Known Bugs & Issues

• Test Coverage: Only ~70% of features have comprehensive tests
• Protocol Integration: Specific DeFi protocols (Orca, Saber, Raydium) not fully integrated
• Documentation: External documentation removed, only inline code docs available

🔧 Technical Debt

• Code Warnings: ~50+ compiler warnings (mostly unused variables)
• Error Handling: Some edge cases may not be properly handled
• Performance: Not fully optimized for high-throughput scenarios
