## 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 = [[q06, q16, qa6, qr6], [06], [06, X6, _6], _6, q06, qa6, qr6, [[q06, 06, q16, X6, R], [q06, _6, qr6, _6, S], [q16, _6, qa6, _6, L]]]

操作後

derived = [[q06, q16, qa6, qr6], [06], [06, X6, _6], [[q06, _6, qr6, _6, S], [q06, 06, q16, X6, R], [q16, _6, qa6, _6, 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 = [[06], q06, _6]

操作後

derived = [[q06, 0, [[0, 06]]]]

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, [q06, 0, [[0, 06]]], 06, [q06, 06, q16, X6, R]]

操作後

derived = [step, [q16, 1, [[0, X6]]]]

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, [q16, 1, [[0, X6]]], _6, [q16, _6, qa6, _6, L]]

操作後

derived = [step, [qa6, 0, [[0, X6]]]]

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 = [[06], 2, [[q06, 0, [[0, 06]]], [q16, 1, [[0, X6]]], [qa6, 0, [[0, X6]]]], [step, step]]

操作後

derived = [qa6, 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
