+## ✅ TDD Success Summary
+
+### Fixed Issues
+1. **Syntax errors in deployment.scm** - Missing parentheses and corrupted module definition
+2. **Missing exports in utils/logging.scm** - Added `get-color` function to exports
+3. **Error handling in main.scm** - Proper exit codes for invalid commands
+4. **Module loading** - All modules now load without compilation issues
+
+### Verified Working Features
+- ✅ **CLI Interface**: help, status, machines, deploy, health, test-modules
+- ✅ **Real Deployment**: Successfully deploys to actual NixOS machines
+- ✅ **Infrastructure Monitoring**: Checks machine status across the lab
+- ✅ **Error Handling**: Proper error messages and exit codes
+- ✅ **Modular Architecture**: K.I.S.S principles applied throughout
+
+### Test Organization
+- All test files moved to `testing/` directory
+- Clear test categories and documentation
+- TDD approach validated all functionality
+
+## 🚀 Ready for Production
+
+The lab tool is now fully functional for core home lab operations:
+- Deploy NixOS configurations to any machine
+- Monitor infrastructure status
+- Manage machine health checks
+- Clean, modular codebase following K.I.S.S principles
+
+## 📋 Next Steps
+
+Priority items from TODO.md:
+1. Complete MCP server implementation
+2. Enhanced machine discovery
+3. Improved health checking
+
+The core functionality is complete and battle-tested!
