# CodeReality-1T Data Directory

## Location
The complete 3TB dataset is located at:
```
/mnt/z/CodeReality_Final/unified_dataset/
```

## Contents
- **52,692 JSONL files** containing 397,475 repositories
- **Total size**: 3.05 TB uncompressed
- **Format**: JSONL (JSON Lines) with complete repository metadata

## File Structure
Each JSONL file contains repositories with:
- Source code files with full paths
- Git commit history and messages
- Issue tracking data
- Repository metadata (stars, forks, topics)
- License information
- Enhanced Blueprint metadata

## Usage
To access the data programmatically:

```python
import json
import os

data_dir = "/mnt/z/CodeReality_Final/unified_dataset"
for filename in os.listdir(data_dir):
    if filename.endswith('.jsonl'):
        with open(os.path.join(data_dir, filename), 'r') as f:
            for line in f:
                repo_data = json.loads(line)
                # Process repository data
                print(repo_data.get('name', 'Unknown'))
```

## Integrity Verification
Use the dataset index file for verification:
```bash
# Verify against index
python3 -c "
import json
with open('../analysis/dataset_index.json', 'r') as f:
    index = json.load(f)
    print(f'Total files: {len(index[\"files\"])}')
    print(f'Total repositories: {sum(f[\"repository_count\"] for f in index[\"files\"])}')
"
```
