有限simple undirected graph的全部edges與candidate subset完整核對。操作=vcover-uncovered-edge-witness；資料={"vertices":["v0","v1","v2","v3","v4","v5"],"edges":[["v0","v1"],["v0","v2"],["v0","v3"],["v0","v4"],["v0","v5"]],"candidate":[]}。請依 exact_ordered_tuple_declared_by_interface 欄序回答。
G001 — 有限simple undirected graph的全部edges與candidate subset完整核對。操作=vcover-uncovered-edge-witness；資料={"vertices":["v0","v1","v2","v3","v4","v5"],"edges":[["v0","v1"],["v0","v2"],["v0","v3"],["v0","v4"],["v0","v5"]],"candidate":[]}。請依 exact_ordered_tuple_declared_by_interface 欄序回答。沿用原題明示的論域、假設與來源 MKO 定義。本題已完成第二對話數理與中英語義覆核，並由原始參數逐題獨立重算模型、答案與每個算術步驟；原題仍為 candidate。
操作前
source roles = [vcover-uncovered-edge-witness]
操作後
derived = [[candidate, edge_coverage_rows, uncovered_edge, cover, boundary]]
條件：無
本頁列完整來源欄序，不需JavaScript；LP三種mode雖同為6欄，角色仍由原mode選，不由答案形狀猜。
規則：source_ordered_fields_without_JS · 依賴：G001
操作前
source roles = [[v0, v1, v2, v3, v4, v5], [[v0, v1], [v0, v2], [v0, v3], [v0, v4], [v0, v5]], []]
操作後
derived = [[v0, v1, v2, v3, v4, v5], [[v0, v1], [v0, v2], [v0, v3], [v0, v4], [v0, v5]], []]
條件：無
carrier非空且至多12，edge端點依JS UTF16<排，再按來源English canonical排序；loop或反向重複edge拒絕，不把圖改成有向或edge cover。
規則：Vcover_complete_simple_undirected_graph_UTF16_then_English_order · 依賴：G001, S001
操作前
source roles = [0, [v0, v1], []]
操作後
derived = [[否, 否], 否]
條件：無
這條edge至少一個endpoint被選才covered，逐完整edge表核對，不用頂點數猜測。

操作前
source roles = [1, [v0, v2], []]
操作後
derived = [[否, 否], 否]
條件：無
這條edge至少一個endpoint被選才covered，逐完整edge表核對，不用頂點數猜測。

操作後
derived = [否, [v0, v1], []]
條件：無
全邊合取，首uncovered edge保來源canonical次序；沒有則null，不用False代null。isolated點沒有責任edge，故可選可不選。
規則：Vcover_COMPLETE_edge_conjunction_FIRST_uncovered_or_NULL · 依賴：G001, S007
操作前
source roles = [[v0, v1], []]
操作後
derived = [否]
條件：無
首反例edge兩端都不在C，已足夠否定全稱vertex cover；outside carrier或duplicate candidate不是此合法false witness。
