React Components Review

Quick review of shared component changes:

✅ Changes Look Good

1. Icon Updates

• Added 3 new icons, removed 2
• Clean enum-based approach
• No breaking changes visible

2. KernTable Cell Components

• Added 18 lines for new cell types
• Likely for data block column rendering
• Follows existing patterns

3. WebSocket Constants

• Added 10 data block-related constants
• Removed 2 old constants
• Clean integration

⚠️ Minor Concerns

1. No Type Exports

• If new cell types were added, ensure TypeScript types are exported
• Frontend should have proper typing for new cells

2. WebSocket Constant Names

• Verify: New constants match backend WebSocket message types exactly
• Typos in WS constants cause silent failures

3. Progress Fix Commit

• Commit: "Progress fix" on Jan 22
• Question: What progress issue was fixed?
• Recommendation: More descriptive commit messages

📋 Recommendations

1. Verify WebSocket constant names match backend exactly
2. Add TypeScript types for new cell components if missing
3. Test WebSocket integration end-to-end

Status: ✅ APPROVE - Small, focused changes. No blocking issues.
