- **Base Defaults**: Falls back to built-in defaults if all else fails
- **Error Reporting**: Clear error messages for invalid configurations
- **Backup Creation**: Automatic backups before configuration changes

#### Configuration Hot Reload
- **File Monitoring**: Watches `.kollabor/config.json` for changes
- **Live Updates**: Applies changes without restarting the application
- **Plugin Integration**: Automatically incorporates new plugin configurations
- **Validation**: Validates new configuration before applying changes

### Configuration Management Commands

In addition to the `/config` modal, the system supports programmatic configuration:

```python
# Get configuration values
api_url = config.get("core.llm.api_url", "http://localhost:1234")
fps = config.get("terminal.render_fps", 20)

# Set configuration values
config.set("terminal.render_fps", 30)
config.set("plugins.enhanced_input.enabled", False)

# Reload configuration from file
success = config.reload()

# Create configuration backup
backup_path = config.backup_config(".backup")

# Restore from backup
success = config.restore_from_backup(backup_path)

# Validate current configuration
validation = config.validate_config()
if not validation["valid"]:
    print("Configuration errors:", validation["errors"])
```

## Security Considerations

### Security Measures

1. **Input Validation**: All user inputs are validated
2. **Command Filtering**: Only registered commands are executed

# Check current version
python main.py --version

# Identify breaking changes
cat docs/BREAKING_CHANGES.md | grep -A 10 "2.0.0"

# Backup current configuration
cp -r .kollabor .kollabor.backup.$(date +%Y%m%d)
```

**Step 2: Preparation**
```bash
# Update dependencies
pip install --upgrade -r requirements.txt

# Review plugin compatibility
python -c "import core.plugins; print(core.plugins.check_compatibility())"

# Test with dry-run mode
python main.py --dry-run --config-version 2.0
```

**Step 3: Migration**
```bash
# Migrate configuration
python tools/migrate_config.py

# Update plugins
find plugins/ -name "*.py" -exec python tools/update_plugin.py {} \;

# Validate installation
python tests/run_tests.py --version-compatibility
```

#### Rollback Procedures

**Configuration Rollback**:
```bash
# Restore previous configuration
cp .kollabor.backup.20250101/config.json .kollabor/config.json

# Verify rollback
python main.py --verify-config
```

**Application Rollback**:
```bash
# Switch to previous version
git checkout v1.4.0

# Restore dependencies
pip install -r requirements.txt

# Verify functionality
python tests/run_tests.py --quick
```

        "Use new_method() instead.",
        DeprecationWarning,
        stacklevel=2
    )
    return self.new_method(param)

# Migration helper
def migrate_config_v1_to_v2(old_config):
