Original question and givens
The finite simple undirected graph has V={-9, -8, -7, -6, -5, -4} and E={{-9, -8}, {-9, -7}, {-8, -7}}. There are no loops or multiple edges, and repeated representations of the same unordered edge count once. Is the candidate endpoint set {-8, -9} an edge in E?

Conditions: none
Keep EACH bank’s keys/operation/domain distinct:LDL/PULSE/function legacy table underscores,TREE full tree_* with its declared domain,and permissive BASE signed without invented op/domain.All arithmetic respects the binary-primitive contract.
