Fixture — hierarchy-with-children

Endpoint: GET /api/ric/v1/hierarchy/912150?include=parent,children,siblings (Egypt — Place) Schema: hierarchy.schema.json

Demonstrates:

• The 3-axis walk: parent + children + siblings in one response.
• Mixed type_id among children (cities + archaeological sites are both valid children of a country).
• The subject entity (Egypt) never appears in any of the three lists — only its relations.

For Place, hierarchy is resolved via ric_place.parent_id. For other entity types it’s derived from ric_relation_meta.dropdown_code ∈ {has_part, is_part_of, includes, is_included_in, is_superior_of}.
