G001 — 完整metric、total self-map與forall-pairs q<1 contraction責任。操作=contract-boundary；資料={"mode":"q_equal_one","scale":21}。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 = [contract-boundary]
操作後
derived = [[mode, scale, metric_description, q, fixed_point_counterexample, theorem_application_claim]]
條件：無
本頁直接列完整來源欄序，不需JavaScript；contract的6/4/6/6與IVT的8/7/8由原mode選，不補欄也不由答案形狀猜。
規則：source_ordered_fields_without_JS · 依賴：G001
操作前
source roles = [q_equal_one, 21]
操作後
derived = [q_equal_one, 21, two_point_metric, 1, identity_map_has_two_fixed_points, 否]
條件：無
q1的two-point identity有兩fixed points；非self-map不能迭代於同空間；(0,s)上(x+s)/2的fixed point s在外；sampled_pairs只保來源範圍敘述，沒提供可重算的完整metric/map，不冒稱已驗numeric反例。
規則：Contraction_original_boundary_mode_actual_scope_not_invented_witness · 依賴：G001, S001
S002 · premise_and_result_audit — 回到原始資料與本步條件核對，不把單向推論誤稱等價。S001 · premise_and_result_audit — 回到原始資料與本步條件核對，不把單向推論誤稱等價。(q_equal_one, 21, two_point_metric, 1, identity_map_has_two_fixed_points, 否)
依上列完整代值及條件核對得到原題答案；原題編號、格式與狀態保持不變。
覆核日期：2026-10-26
原題、答案、步驟表達式、數值 AST 與既有歷史保持原樣；原來的候選狀態屬於來源歷史，不覆寫為形式化證明。
