  - Fixing or improving documentation.
  - Improvements to Maven configuration.

Guidelines for any code contributions:

1.  Any significant changes should be accompanied by tests. The project already
    has good test coverage, so look at some existing tests if you're unsure how
    to go about it.
2.  All contributions must be licensed Apache 2.0 and all files must have a copy

```

## Testing Strategy

### Unit Tests
- Individual component testing for each feature
- Mock-based testing for protocol interactions
- State machine validation

### Integration Tests
- Feature interaction testing
- Network failure simulation
- Performance benchmarking
- Compatibility testing with Windows Server 2016/2019/2022

### Test Infrastructure Requirements
