# Correct the specialty at the group-facility-network level

`PATCH /facilities/tenant-group-facility-network-specialties/specialty`

Resolves the FK chain from TenantGroupFacilityNetworkSpecialty (Level 5) to the parent TenantGroupFacilitySpecialty (Level 3) and replaces its tenant_specialty_id by updating that Level-3 record. Use this for data-correction scenarios where a group-facility-network specialty record is linked to the wrong specialty and you need to scope the correction to a single network association without cascading across all locations — for the broader group-facility correction, use PATCH /facilities/tenant-group-facility-specialties/specialty instead. Does not trigger termination events. Because this operation delegates to the Level-3 update, the response body is shaped like the Level-3 record (id, tenantSpecialtyId, data) — not a Level-5-specific record.
