+# Implementation Checklist
+
+## ✅ Completed Tasks
+
+### Core Functionality
+- [x] Created `tcp_data_loader_split.py` - splits data into multiple files
+- [x] Created `folder_loader.js` - loads split files from folder
+- [x] Created `folder_integration.js` - bridges loader with visualization
+- [x] Modified `index.html` - added folder loading UI
+- [x] Modified `viewer_loader.js` - integrated folder loading
+- [x] Preserved backward compatibility with CSV upload
+
+### Data Generation
+- [x] Reused exact TCP flow detection from original loader
+- [x] Generate manifest.json with metadata
+- [x] Generate packets.csv for timearcs
+- [x] Generate flows_index.json for flow summaries
+- [x] Generate individual flow files (flows/*.json)
+- [x] Generate ip_stats.json
+- [x] Generate flag_stats.json
+- [x] Support compressed CSV input (.csv.gz)
+- [x] Progress tracking during generation
+
+### Loading & Display
+- [x] File System Access API integration
+- [x] Progressive loading with progress bar
+- [x] Async CSV parsing with chunking
+- [x] Load packets for visualization
+- [x] Load flow summaries
+- [x] On-demand flow loading
+- [x] Flow caching for performance
+- [x] Error handling throughout
+
+### User Interactions
+- [x] Data source selector (CSV vs Folder)
+- [x] Open folder button
+- [x] Folder info display
+- [x] IP selection filtering
+- [x] Time range clicks on overview bars
+- [x] Flow list modal for time ranges
+- [x] Flow details modal with packets
+- [x] Search in flow lists
+- [x] Modal dragging (existing feature)
+
+### Documentation
+- [x] README_FOLDER_LOADING.md - comprehensive guide
+- [x] IMPLEMENTATION_SUMMARY.md - technical overview
+- [x] Code comments throughout
+- [x] Usage examples script
+- [x] Test script with verification
+
+### Testing
+- [x] Created test_split_loader.py
+- [x] Synthetic TCP traffic generation
+- [x] File structure verification
+- [x] Content validation
+- [x] Example usage scripts
+
+## 📋 Testing Checklist
+
+### Unit Tests
+- [ ] Run `python test_split_loader.py`
+- [ ] Verify all files created
+- [ ] Verify content structure
+- [ ] Check flow states (complete, incomplete, RST)
+
+### Integration Tests
+- [ ] Generate test data with existing CSV file
+- [ ] Open folder in Chrome/Edge
+- [ ] Verify packets load correctly
+- [ ] Verify flows index loads
+- [ ] Verify IP statistics display
+- [ ] Verify flag statistics display
+
+### UI Tests
+- [ ] Toggle between CSV and Folder modes
+- [ ] Upload CSV file (legacy mode)
+- [ ] Open folder (new mode)
+- [ ] Progress bar displays correctly
+- [ ] Folder info shows correct data
+- [ ] IP checkboxes populate
+- [ ] Select/deselect IPs
+- [ ] Overview chart displays
+- [ ] Timearcs render correctly
+
+### Interaction Tests
+- [ ] Click on overview bar → flow list appears
+- [ ] Search flows in modal
+- [ ] Click on flow → details load
+- [ ] View flow packets in table
+- [ ] Close modals properly
+- [ ] Multiple interactions work smoothly
+
+### Performance Tests
+- [ ] Test with 10k packets
+- [ ] Test with 100k packets
+- [ ] Test with 1M packets (if available)
+- [ ] Check memory usage
+- [ ] Check loading time
+- [ ] Check responsiveness
+
+### Browser Compatibility
+- [ ] Chrome 86+ (primary)
+- [ ] Edge 86+ (primary)
+- [ ] Opera 72+ (if available)
+- [ ] Firefox (CSV fallback)
+- [ ] Safari (CSV fallback)
+
+### Error Handling
+- [ ] Cancel folder selection
+- [ ] Select wrong folder (no manifest)
+- [ ] Missing flow files
+- [ ] Corrupted JSON files
+- [ ] Network errors (if applicable)
+- [ ] Large file timeout
+
+## 🔄 Next Steps (Optional Enhancements)
+
+### High Priority
+- [ ] Add flow search index for faster lookup
+- [ ] Implement virtual scrolling for large flow lists
+- [ ] Add export functionality (filtered data → CSV)
+- [ ] Optimize memory usage for large datasets
+
+### Medium Priority
+- [ ] Add compressed flow files support (.json.gz)
+- [ ] Implement chunked packet files by time range
+- [ ] Add multiple folder comparison mode
+- [ ] Create flow graph visualization
+
+### Low Priority
+- [ ] Server mode for enterprise (HTTP server)
+- [ ] Machine learning integration (anomaly detection)
+- [ ] Real-time data streaming
+- [ ] Custom color schemes
+- [ ] Advanced filtering options
+
+## 🐛 Known Issues
+
+### Limitations
+1. File System Access API only in Chrome/Edge/Opera
+2. Large datasets (>5M packets) may cause memory issues
+3. No streaming for very large files yet
+4. Flow caching has no size limit (could grow large)
+
+### Workarounds
+1. Use CSV fallback for Firefox/Safari
+2. Use `--max-records` for large datasets
+3. Implement chunked loading (future)
+4. Add cache size limit (future)
+
