  • G001 — deterministic single-tape signature、exact configuration semantics與decider total-correctness boundary。操作=tm-exact-step-trace；資料={"states":["q08","q18","qa8","qr8"],"input_alphabet":["08"],"tape_alphabet":["08","X8","_8"],"blank":"_8","start_state":"q08","accept_state":"qa8","reject_state":"qr8","transitions":[["q08","08","q18","X8","R"],["q08","_8","qr8","_8","S"],["q18","_8","qa8","_8","L"]],"input":["08"],"steps":2}。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。

逐步推導

S001 · implies

操作前

source roles = [tm-exact-step-trace]

操作後

derived = [[input, step_budget, configurations, step_outcomes, final_state, local_outcome, global_decider_certificate, boundary]]

條件：無

直接列來源完整欄序，不需JavaScript；原題、布林旗標、數學物件與非聲稱保持分層。

步驟識別與依賴

規則：source_ordered_fields_without_JS · 依賴：G001

S002 · implies

操作前

source roles = [[q08, q18, qa8, qr8], [08], [08, X8, _8], _8, q08, qa8, qr8, [[q08, 08, q18, X8, R], [q08, _8, qr8, _8, S], [q18, _8, qa8, _8, L]]]

操作後

derived = [[q08, q18, qa8, qr8], [08], [08, X8, _8], [[q08, _8, qr8, _8, S], [q08, 08, q18, X8, R], [q18, _8, qa8, _8, L]], 是]

條件：無

三個清單皆非空且唯一；input是blank-free tape子集，但state與字母標籤不要求不相交。每個(from,read)的來源NUL-joined key唯一、halt無出邊。partial table合法，不補reject規則；canonical transition序與UTF16集合序分開。

步驟識別與依賴

規則：TM_complete_signature_partial_transition_table_allowed · 依賴：G001, S001

S003 · implies

操作前

source roles = [[08], q08, _8]

操作後

derived = [[q08, 0, [[0, 08]]]]

條件：無

初始head0、input放0起的整數格，其餘全blank；稀疏記錄僅保非blank。tape可往負index伸展。

步驟識別與依賴

規則：TM_exact_initial_configuration_blank_elsewhere · 依賴：G001, S002

S004 · calculation

操作前

TM exact integer head move0 := sum(0, 1)

操作後

TM exact integer head move0 = 1

條件：無

依原始角色與已證中間量精確代值，分母先核非零，不用浮點近似。

步驟識別與依賴

規則：exact_rational_arithmetic · 依賴：G001, S003

S005 · implies

操作前

source roles = [0, [q08, 0, [[0, 08]]], 08, [q08, 08, q18, X8, R]]

操作後

derived = [step, [q18, 1, [[0, X8]]]]

條件：無

先在舊head寫字（blank刪格），再換state及移head；全部L/R/S按原rule，不混成停機語意。

步驟識別與依賴

規則：TM_source_rule_exact_read_write_state_move · 依賴：G001, S004

S006 · calculation

操作前

TM exact integer head move1 := sum(1, -1)

操作後

TM exact integer head move1 = 0

條件：無

依原始角色與已證中間量精確代值，分母先核非零，不用浮點近似。

步驟識別與依賴

規則：exact_rational_arithmetic · 依賴：G001, S005

S007 · implies

操作前

source roles = [1, [q18, 1, [[0, X8]]], _8, [q18, _8, qa8, _8, L]]

操作後

derived = [step, [qa8, 0, [[0, X8]]]]

條件：無

先在舊head寫字（blank刪格），再換state及移head；全部L/R/S按原rule，不混成停機語意。

步驟識別與依賴

規則：TM_source_rule_exact_read_write_state_move · 依賴：G001, S006

S008 · implies

操作前

source roles = [[08], 2, [[q08, 0, [[0, 08]]], [q18, 1, [[0, X8]]], [qa8, 0, [[0, X8]]]], [step, step]]

操作後

derived = [qa8, accept, 否]

條件：無

已halt才接受／拒絕；budget用盡或stuck不是普通reject，也不證永久不停止。一個input的有限trace不提供all-input decider證書。

步驟識別與依賴

規則：TM_finite_trace_input_budget_scope_NOT_global_decider · 依賴：G001, S007
