## 📋 Issues by File and Category ## 🔄 Maintenance Recommendations
### Core Module Issues ### For Production Deployment
#### `src/cli/Main.py` 1. **Rate Limiting**: Consider Redis-based rate limiter for distributed deployments
2. **Session Storage**: Implement Redis/database for auth failure tracking
3. **Monitoring**: Add Prometheus/Grafana for performance metrics
4. **Caching**: Consider Redis for HTTP response caching under high load
5. **Audit Logging**: Implement SQLAlchemy event listeners for data change tracking
- [ ] **Code Quality**: Class `SeriesApp` duplicates core `SeriesApp` from `src/core/SeriesApp.py` ### For Future Enhancements
- Consider consolidating or using inheritance
- Line 35: `_initialization_count` duplicated state tracking
- [ ] **Type Hints**: `display_series()` doesn't validate if `serie.name` is `None` before using it
- [ ] **Import Organization**: Imports not sorted (lines 1-11) - should follow isort convention
- [ ] **Error Handling**: `NoKeyFoundException` and `MatchNotFoundError` are bare except classes - need proper inheritance
- [ ] **Logging**: Logging configuration at module level should be in centralized config
#### `src/core/SeriesApp.py` 1. **Multi-User Support**: Implement row-level security if needed
2. **Performance Profiling**: Profile with large datasets (>10K files)

#### `src/core/providers/enhanced_provider.py`
- [ ] **Type Hints**: Class constructor `__init__()` missing type annotations (lines 40-96)
- [ ] **Documentation**: Bare exception handlers at lines 418-419 - need specific exception types
- [ ] **Code Quality**: `with_error_recovery` decorator imported but usage unclear
- [ ] **Performance**: `_create_robust_session()` method not shown but likely creates multiple session objects
#### `src/core/interfaces/providers.py`
- [ ] Need to verify if any abstract methods lack type hints and docstrings
#### `src/core/exceptions/Exceptions.py`
- [ ] Need to verify custom exception hierarchy and documentation
