- RelationType enum (9 values), PersonRelationship entity with
@ToString(exclude = "notes") and LAZY person FKs.
- PersonRelationshipRepository with the network bulk fetch, the
per-person subgraph fetch, and the existsBy check for the circular
PARENT_OF guard.
- Six DTO records: CreateRelationshipRequest, RelationshipDTO,
PersonNodeDTO, NetworkDTO, InferredRelationshipDTO,
InferredRelationshipWithPersonDTO. @Schema(REQUIRED) on every
always-populated field so OpenAPI/TS codegen stays accurate.
- Person entity gains familyMember, PersonSummaryDTO gains
isFamilyMember, both PersonRepository projections select
p.family_member.
- Three new ErrorCodes: RELATIONSHIP_NOT_FOUND, CIRCULAR_RELATIONSHIP,
DUPLICATE_RELATIONSHIP.
