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。

• mko-complete-metric-space

all off-diagonal positive distances=[6, 13, 17, 6, 11, 15, 13, 11, 22, 17, 15, 22]

minimum positive distance delta=6>0

arbitrary Cauchy sequence in Fin(4);choose epsilon=delta=6>0

some N has every m,k>=N with d(x_m,x_k)<6;minimum separation forces x_m=x_k

all tail terms equal x_N;typed sequence guarantees x_N in Fin(4)

for every positive eta,all k>=N have distance(x_k,x_N)=0<eta;limit belongs to same space

qualified finite metric;delta=6;selected evidence mode=finite_minimum_separation

selected evidence sufficient=是;space completeness is not denied by sample insufficiency
