# Technical Specification - Replication

**Version**: v1.0.0 | **Status**: Planned | **Last Updated**: February 2026

**Module**: `codomyrmex.cache.replication`  
**Last Updated**: 2026-01-29

## 1. Purpose

Cross-region cache synchronization and consistency

## 2. Architecture

### 2.1 Components

```
replication/
├── __init__.py          # Module exports
├── README.md            # Documentation
├── AGENTS.md            # Agent guidelines
├── SPEC.md              # This file
├── PAI.md               # Personal AI context
└── core.py              # Core implementation
```

### 2.2 Dependencies

- Python 3.10+
- Parent module: `cache`

## 3. Interfaces

### 3.1 Public API

```python
# Primary exports from codomyrmex.cache.replication
# __all__ is empty — no public interface exported yet.
Not yet implemented.
```

### 3.2 Configuration

Environment variables:
- `CODOMYRMEX_*`: Configuration options

## 4. Implementation Notes

### 4.1 Design Decisions

1. **Deferred implementation**: Core replication logic is not yet exported; `__all__` is empty and imports are commented out pending design finalization.

### 4.2 Limitations

- Active-active write conflicts are not automatically resolved; use versioning or last-write-wins.
- Replication lag is not surfaced as a metric by default.

## 5. Testing

```bash
# Run tests for this module
uv run pytest src/codomyrmex/tests/unit/cache/replication/
```

## 6. Future Considerations

- Implement cross-region cache synchronization with configurable consistency models
- Add conflict resolution strategies for concurrent writes across replicas
