Research direction
Start with the People entity and its @Mapping(Relation.OneToMany) child field, then trace the cascade-save path used before inspecting the SQLite database. Reproduce the example and compare the persisted relation mapping with the expected child relationships; done means the tree structure is stored rather than only an ID.
