Original question and givens
The finite simple undirected graph has V={2, 3, 4, 5, 6} and E={{2, 3}, {2, 4}, {2, 5}}. There are no loops or multiple edges, and repeated representations of the same unordered edge count once. Is the candidate endpoint set {2, 7} 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.
