G001 — transition=[from,input-or-null,to]且允許empty alphabet/final set的finite epsilon-NFA。操作=nfa-bounded-search-boundary；資料={"states":["s2","m2","f2","d2"],"alphabet":["a2","b2"],"start_state":"s2","final_states":["f2"],"transitions":[["s2",null,"m2"],["s2",null,"d2"],["m2","a2","m2"],["m2","b2","f2"]],"input":["a2","a2","b2"],"max_steps":1}。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-bounded-search-boundary;original snapshot and mathematics retained
操作後
explicit ordered source output fields=[input, max_steps, found_accepting_path, rejection_claim, boundary]
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。
規則：source_ordered_interface_explicit_without_javascript · 依賴：G001
操作前
ORIGINAL transition index=0;[from,input_or_null,to]=[s2, null, m2];state carrier=[s2, m2, f2, d2];alphabet=[a2, b2]
操作後
state endpoints legal;symbol either declared input or null EPS consuming0;ORIGINAL row position retained,including duplicate rows
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。

操作前
ORIGINAL transition index=1;[from,input_or_null,to]=[s2, null, d2];state carrier=[s2, m2, f2, d2];alphabet=[a2, b2]
操作後
state endpoints legal;symbol either declared input or null EPS consuming0;ORIGINAL row position retained,including duplicate rows
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。

操作前
ORIGINAL transition index=2;[from,input_or_null,to]=[m2, a2, m2];state carrier=[s2, m2, f2, d2];alphabet=[a2, b2]
操作後
state endpoints legal;symbol either declared input or null EPS consuming0;ORIGINAL row position retained,including duplicate rows
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。

操作前
ORIGINAL transition index=3;[from,input_or_null,to]=[m2, b2, f2];state carrier=[s2, m2, f2, d2];alphabet=[a2, b2]
操作後
state endpoints legal;symbol either declared input or null EPS consuming0;ORIGINAL row position retained,including duplicate rows
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。
規則：nfa_EVERY_original_relation_row_roles_empty_multi_EPS_legal · 依賴：G001, S004
操作前
ORIGINAL states=[s2, m2, f2, d2],alphabet=[a2, b2],start=s2,final_states=[f2];complete relation=[[s2, null, m2], [s2, null, d2], [m2, a2, m2], [m2, b2, f2]]
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
空final set合法且辨識空語言；空alphabet也合法。定義合格不保存在accepting path，亦不推deterministic或DFA等價。
規則：nfa_qualified_definition_EMPTY_alphabet_finals_edges_allowed · 依賴：G001, S005
操作前
ORIGINAL input=[a2, a2, b2];actual start configuration=[s2, 0];max_steps=1
操作後
depth0 accepted=否;one finite FULL-input final path suffices;dead alternatives do not veto success
條件：無
搜尋步數計transition，EPS雖不耗input仍占一步。起點final可接受空字；有一條完整有限成功路徑即足夠，不需所有分支成功。
規則：nfa_bounded_initial_and_finite_path_acceptance_scope · 依賴：G001, S006
操作前
ORIGINAL depth=0;frontier in ORIGINAL-state/position display order=[[s2, 0]]
操作後
ALL [from,ORIGINAL transition index,next_or_null] rows=[[[s2, 0], 0, [m2, 0]], [[s2, 0], 1, [d2, 0]], [[s2, 0], 2, null], [[s2, 0], 3, null]];next distinct configs=[[m2, 0], [d2, 0]];hit FULL-input final=否
條件：無
逐全部config與原relation列驗一步，按深度去重；input位置依symbol或null只增1或0。有限EPS循環只增加可達路徑，不是一條無窮接受run。
規則：nfa_ALL_nondeterministic_bounded_frontier_not_infinite_cycle · 依賴：G001, S007
操作前
ORIGINAL bound=1;input=[a2, a2, b2];found_accepting_path=否
操作後
rejection_claim fixed No;bounded flag alone supplies no GENERAL rejection certificate;any actual completeness argument must be established separately
條件：無
最後No保留不由有限測試作一般拒絕推論，不否定found=True。某有限模型若另證此界已完整涵蓋configuration，可另判實際拒絕；不能把不同的完整判定偷換成本題found旗標。
