🎉 Conclusion

While we have 100% ADR compliance, these remediation elements will elevate our implementation from "compliant" to "exemplary." The focus should be on:

1. Completing the testing pyramid with comprehensive E2E tests
2. Enhancing CI/CD pipeline with quality gates and security scanning
3. Implementing performance monitoring with benchmarks and regression detection
4. Expanding documentation with comprehensive guides and examples
5. Strengthening security posture with vulnerability scanning and dependency management

This remediation plan will transform our already excellent TDD implementation into a world-class, production-ready component library that exceeds industry standards and serves as a model for Rust/Leptos development.

Next Steps: Begin with Phase 1 critical infrastructure implementation, focusing on E2E test completion and CI/CD pipeline enhancement.

Timeline: 8 weeks for complete implementation Priority: Start with E2E tests and CI/CD enhancement Success Metric: 100% test coverage across all testing layers
