- Add PersonService.setFamilyMember (write, @Transactional) and
findAllFamilyMembers; PersonRepository gains the
findByFamilyMemberTrueOrderBy projection.
- RelationshipService orchestrates PersonService + the inference
service; never reaches into PersonRepository directly. addRelationship
guards self-relationship, year range, circular PARENT_OF (Nora B2),
and DataIntegrityViolation→DUPLICATE_RELATIONSHIP. deleteRelationship
enforces ownership from either side (Nora B1).
- Extend RelationshipDTO with personDisplayName + birth/death year so
the frontend can render rows from either viewpoint.
- 8 unit tests, written against a stub (red), then green: FORBIDDEN
delete, CIRCULAR add, DUPLICATE add, self-relationship, year range,
happy-path persistence, ownership-from-object, RELATIONSHIP_NOT_FOUND.
Full backend suite: 1399/1399 green.
