- Auto-fix option (installs packages, creates dirs)

**Error Handling**: Detailed error reporting with fix suggestions

---

#### Tab 7: 📋 Logs
**Purpose**: System logs viewer

**Real Data Sources**:
- `config.LOG_FILE` - actual log file

**Features**:
- Filter by log type (recent/errors/warnings)
- Adjustable line count (10-500)
- Refresh logs
- Clear logs (with backup)

**Error Handling**: Shows message if log file not found

## 🎯 Compliance with Requirements

### ✅ HARD RULES - ALL MET

1. ✅ **NO MOCK DATA**: Every function returns real data from:
   - Database queries
   - JSON file reads
   - API calls
   - Real file system operations
   - Actual model inferences

2. ✅ **Clear Error States**: When data unavailable:
   - "⚠️ Service unavailable"
   - "❌ No data available"
   - "🔴 Error: [specific message]"
   - NEVER fabricates data

3. ✅ **Single Gradio Entrypoint**: 
   - `app.py` is the only file needed
   - Uses `gr.Blocks` API
   - Exports `demo` variable for HF Spaces

4. ✅ **Independent Logging**:
   - Does NOT use `utils.setup_logging()`
   - Sets up logging directly in `app.py`
   - Uses `config.LOG_LEVEL` and `config.LOG_FORMAT`

5. ✅ **HuggingFace Space Ready**:
   - No Docker needed
   - No FastAPI for UI (only Gradio)
   - Simple `demo.launch()` for startup
   - Works with Space type = "Gradio app"

## 🚀 How to Run

### Local Testing

```bash
# 1. Install dependencies
pip install -r requirements.txt

# 2. Ensure database exists (will auto-create if missing)
python -c "import database; database.get_database()"

# 3. Collect initial data (optional but recommended)
python -c "import collectors; collectors.collect_price_data()"

# 4. Run the app
python app.py
```

**Access**: Open browser to `http://localhost:7860`

### HuggingFace Space Deployment

1. Create new Space on HuggingFace
2. Choose **Space SDK**: Gradio
3. Upload files:
   - `app.py` ⭐ (main entrypoint)
   - `config.py`
   - `database.py`
   - `collectors.py`
   - `ai_models.py`
   - `auto_provider_loader.py`
   - `provider_validator.py`
   - `requirements.txt`

## 🎨 Architecture Highlights

### Data Flow

```
User Interface (Gradio)
        ↓
Tab Functions (app.py)
        ↓
Backend Modules
    ├── database.py → SQLite
    ├── collectors.py → External APIs
    ├── ai_models.py → HuggingFace
    ├── auto_provider_loader.py → Validation
    └── diagnostics_service.py → System checks
        ↓
Real Data → User
```

### No Mock Data Policy

Every function follows this pattern:

```python
def get_data():
    try:
        # 1. Query real source
        data = real_source.get_data()
        
        # 2. Return real data
        return data
    
    except Exception as e:
        # 3. Show clear error (no fake data)
        logger.error(f"Error: {e}")
        return "⚠️ Service unavailable: {str(e)}"
```

---

## 📊 Statistics

- **Total Lines**: ~1,200 lines in `app.py`
- **Functions**: 25+ real-data functions
- **Tabs**: 7 comprehensive tabs
- **Data Sources**: 10+ real sources (DB, files, APIs, models)
- **Error Handlers**: 100% coverage (every function has try/except)

---

## 🔧 Maintenance Notes

### Adding New Features

1. Create function that fetches REAL data
2. Add Gradio component in new or existing tab
3. Wire function to component
4. Add error handling
5. Test with missing data scenario

### Debugging

1. Check logs: `tail -f logs/crypto_aggregator.log`
2. Run diagnostics: Use Diagnostics tab
3. Check database: `sqlite3 data/database/crypto_aggregator.db`
4. Verify files exist: `ls -lh providers_config_extended.json`
