原題與已知條件

完整有限拓撲上每一對distinct points的disjoint open-neighborhood witnesses。操作=hausdorff-full-audit；資料={"points":["a19","b19","c19"],"topology":[["a19","b19","c19"],["a19","b19"],["a19","c19"],["a19"],["b19","c19"],["b19"],["c19"],[]]}。請依 exact_ordered_tuple_declared_by_interface 欄序回答。

  • G001 — 完整有限拓撲上每一對distinct points的disjoint open-neighborhood witnesses。操作=hausdorff-full-audit；資料={"points":["a19","b19","c19"],"topology":[["a19","b19","c19"],["a19","b19"],["a19","c19"],["a19"],["b19","c19"],["b19"],["c19"],[]]}。請依 exact_ordered_tuple_declared_by_interface 欄序回答。

定義與適用範圍

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。
