## 🎯 Core Objectives

1. **Backend Benchmarking**: Compare Russian vs IBM quantum backends on multilingual edit reliability
2. **QEC Integration**: Extend REPAIR with Quantum Error Correction for hallucination resilience
3. **Performance Visualization**: Interactive dashboards across languages, domains, and edit types
4. **Hugging Face Integration**: Deploy demos, models, and datasets to HF Spaces

## ✨ Key Features

### 🔬 Backend Comparison
