🐛 Critical Issues Found

None - All critical functionality working correctly

Minor Performance Issues:

1. Large graph rendering (1000+ nodes) slower than target

   • Impact: Low (most use cases <500 nodes)
   • Priority: Medium
   • Solution: Implement virtualization/LOD

2. Burst traffic handling slightly over 1s threshold

   • Impact: Low (rare edge case)
   • Priority: Low
   • Solution: Optimize batch processing
