-## Completed Tasks
 
-- Entity rendering pipeline is fully implemented for Box, Sphere, Model types
-- Color and texture data are parsed, stored, and logged; texture download and caching is implemented (SHA256-based)
-- Visual application of color/texture is pending StardustXR API support (see ENTITY_TROUBLESHOOTING.md)
-- Connection persistence bug is fixed (see IMPLEMENTATION_COMPLETE.md)
+## Completed Tasks (Concise)
+
+- Entity rendering pipeline: Box, Sphere, Model (GLTF/GLB, HTTP, primitives)
+- Color/texture: parsed, stored, logged, downloaded, cached (visual application pending API)
+- Debug logging: opt-in, covers entity lifecycle, packets, network
+- Test suite: entity parsing, structure, and protocol validation
+- Troubleshooting: see ENTITY_TROUBLESHOOTING.md

 ## Conclusion
 
-All feasible items from the problem statement have been successfully implemented. The implementation follows best practices:
-
-✅ **Minimal Changes** - Reused existing infrastructure where possible  
-✅ **Backward Compatible** - All changes opt-in via environment variables  
-✅ **Well Tested** - Comprehensive test coverage  
-✅ **Well Documented** - Complete troubleshooting guide  
-✅ **Secure** - Zero security vulnerabilities  
-✅ **Production Ready** - All tests passing
-
-The remaining items (color tinting visual application, HMAC workaround) are blocked by external dependencies and are properly documented for future work.
+All feasible items have been implemented with minimal, well-tested, and secure changes. Remaining work (color/texture visual application, ATP, more entity types) is blocked by external dependencies and tracked in IMPLEMENTATION_COMPLETE.md.
