G001 — transition=[from,input-or-null,to]且允許empty alphabet/final set的finite epsilon-NFA。操作=nfa-epsilon-closure；資料={"states":["s4","m4","f4","d4"],"alphabet":["a4","b4"],"start_state":"s4","final_states":["f4"],"transitions":[["s4",null,"m4"],["s4",null,"d4"],["m4","a4","m4"],["m4","b4","f4"]],"seed_states":["s4"]}。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 operation=nfa-epsilon-closure;original snapshot and mathematics retained
操作後
explicit ordered source output fields=[seed_states, epsilon_closure, closure_certificate, certificate]
條件：無
原題快照保留歷史介面；此處直接列來源欄序，不依賴JavaScript。tag與No保聲稱範圍，固定來源排序不冒充數學證明。

操作後

條件：無
這是relation不是單值total函數，duplicate／多值／缺邊皆保原資料；null消耗0但不是一個alphabet字串。

操作後
states nonempty with actual start;alphabet/final set/relation MAY be EMPTY;definition qualification does NOT prove determinism,totality,DFA equivalence or a successful run

條件：無
每個新增state有前一集合的EPS前驅，故有有限seed路徑；任何含seed且EPS封閉的集合都須含每一層。有限states只會新增有限次，穩定時即完整且最小closure，不消耗input。
