Q57, run 2026-11-05-1819-sonnet-query-graphdb
Which is the nearest entity that Cerid Guven Energy SA and Cerid Telecom SA both have in their chains of parents?
Tests: Paths: the nearest common ancestor, below the top of the group.
Expected: entity = E5002
sparql run 1
None. E5011's only ancestor is E5167, while E5013's ancestors are E5006, E5002 and E5001, so the chains share no entity.
JSON: {"entity": "none"}
Why: entity: expected E5002, got none
sparql run 2
None found. E5011's chain ends at E5167, and E5013's chain runs E5006 → E5002 → E5001 with no overlap.
JSON: {"entity": "none"}
Why: entity: expected E5002, got none
sparql run 3
E5002. Cerid Telecom (E5013) has parent E5002, and Cerid Guven Energy (E5121) goes through E5011 to E5002.
JSON: {"entity": "E5002"}
sparql run 4
E5002. E5011's parent E5167 shares an LEI with E5005, which sits under E5002, and E5013's chain runs E5006, E5002, E5001. That reading depends on treating E5167 and E5005 as the same entity.
JSON: {"entity": "E5002"}
sparql run 5
E5002. E5011 reaches it through E5167 (= E5005), and E5013 reaches it through E5006.
JSON: {"entity": "E5002"}
