# Closure Note

This proposal has been **SUPERSEDED** by `fix-command-formatter-coupling`.

## Reason for Closure

The architectural problems identified in this proposal were addressed more elegantly by the explicit formatter configuration approach implemented in `fix-command-formatter-coupling`:

### Problems Addressed

1. ✅ **Centralized Registration Vulnerability**: Solved via `LANGUAGE_FORMATTER_CONFIG` - explicit configuration prevents accidental deletion
2. ✅ **Type Safety**: `FormatterSelector` provides clear interfaces with proper type hints
3. ✅ **Lack of Testing**: Comprehensive golden master tests validate all language formatters
4. ✅ **Language Isolation**: Each language has explicit formatter strategy configuration

### Implementation Chosen

Instead of the plugin-based auto-registration proposed here, we chose:
- **Explicit Configuration**: `LANGUAGE_FORMATTER_CONFIG` dictionary
- **Service-Based Selection**: `FormatterSelector` class
- **Simpler Architecture**: No metaclasses or auto-registration complexity
- **Full Backward Compatibility**: Existing code works unchanged

### Benefits Achieved

All benefits from this proposal were achieved:
1. ✅ Safety: New languages don't affect existing ones
2. ✅ Maintainability: Each language formatter is independent
3. ✅ Extensibility: Easy to add new languages
4. ✅ Quality: Type-safe with comprehensive tests

## Conclusion

This proposal is **CLOSED as SUPERSEDED**. The chosen solution is simpler, more maintainable, and achieves all the desired outcomes.
