Comprehensive review completed using specialized agents for code quality, performance, documentation, and security.

Overall Assessment: ✅ Good with Minor Issues

Key Findings:

🟡 Minor Issues:

• Hidden UI element with TODO comment suggests incomplete implementation
• Magic numbers in CSS could be improved with constants

✅ Positive Aspects:

• Clean separation of concerns with new EditMode enum
• Consistent Vue.js and TypeScript patterns
• Strong security practices with proper input validation
• No performance bottlenecks identified

Security Status: ✅ LOW RISK - No vulnerabilities found

The refactoring demonstrates solid architecture with good Vue.js practices. Address the critical state synchronization issue for production readiness.
