+
+## Known Limitations
+
+1. **Native Dependencies**: Some features (sharp, better-sqlite3) may require manual installation in certain environments
+2. **API Documentation**: Some exports may have different names than initially expected (e.g., HyperedgeStream vs hyperedge)
+3. **Platform Support**: Native bindings are platform-specific; WASM fallback available
+
+---
+
+## Recommendations
+
+1. ✅ Package is ready for alpha testing
+2. ✅ All advertised features are present and accessible
+3. ✅ Documentation in node_modules is comprehensive
+4. 💡 Consider adding a peer dependency for better-sqlite3
+5. 💡 Update main documentation if export names differ from examples
+
+---
+
+## Conclusion
+
+**VERIFICATION PASSED** ✅
+
+The agentdb@2.0.0-alpha.2.11 package is successfully published and working correctly. All 5 attention mechanisms are fully implemented and accessible, including the hyperbolic attention mechanism. The package includes all advertised RuVector packages and features.
+
+The package is ready for alpha testing and user feedback.
