The finite simple undirected graph has V={-2, -1, 0, 1, 2} and E={{-2, -1}, {0, 1}}. There are no loops or multiple edges, and repeated representations of the same unordered edge count once. Is the candidate endpoint set {-2, 2} an edge in E?

Definition and scope
Use the original question domain, assumptions and cited MKO definitions. This item has second-context mathematical and bilingual review, with the model, answer and every arithmetic step independently recomputed from the original parameters; the source question remains a candidate.
source roles = [qf-simple-graph-edge-membership, [E, V, operation, u, v]]
After
derived = [edge_membership, no-invented-domain]
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.
Type EVERY RAW SAFE label,distinctness and THIS bank’s cardinality bound;empty is allowed.Sort ONLY the derived representation,not original JSON.Do not exchange TREE and LDL limits.
source roles = [LDL raw edges ORIGINAL, 0, [-2, -1]]
After
derived = [[-2, -1]]
Conditions: none
BEFORE deduplication,type EACH RAW pair as EXACTLY TWO SAFE components.Identical rows may be representation duplicates,but no unvalidated cell may be silently discarded.
source roles = [LDL raw edges ORIGINAL, 1, [0, 1]]
After
derived = [[0, 1]]
Conditions: none
BEFORE deduplication,type EACH RAW pair as EXACTLY TWO SAFE components.Identical rows may be representation duplicates,but no unvalidated cell may be silently discarded.
Type the WHOLE raw edge list,then normalize undirected endpoints/deduplicate;reversed duplicates are allowed.INPUT edges have no loops/outside endpoints,while isolated vertices stay in V.TREE raw E does NOT acquire LDL’s200-entry limit.

No
The full substitutions and premise checks give the original answer; source identity,format and status are unchanged.
