It's acceptable for implementation classes to be written to fit into existing code, but new classes must not instantiate managed properties or implement getters manually.

This is preferred:

```groovy
public interface NewThing {
    Property<String> getSomeProperty()
}
```

This is acceptable:

```groovy
public interface NewThing {

/**
 * Tests for the {@link AllocInfo} interface.
 * Since {@code AllocInfo} only declares getters, the tests focus on
 * verifying that implementations honour the contract.
 */
@ExtendWith(MockitoExtension.class)
public class AllocInfoTest {

    @Mock
    AllocInfo mockAllocInfo;

    /**
     * Happy path – verifies that getters return the values supplied by the
     * implementation.
     */
