fix(ship): PR body template slot for permanent-test admission decisions

 reviewer-side duty 已要求提出者載明符合哪些條件，author side 先前沒有對稱義務，
 該對稱化屬該 repo 的獨立變更，不在本票 scope。
 
+**Update 2026-08-26（第二次讀數；票維持 active）**：對稱記錄規則自 pr:#530
+（2026-08-25 生效）起的證據窗已累積 12 個 merged PR，遠超「觀察 2-3 個」的門檻。
+逐一比對後找到 2 個合格實例——都是同一位執行者（本 agent）自己交付的 PR：pr:#539
+因 gate finding 新增 7 個永久 regression case、pr:#541 因 gate finding 新增 2 個
+永久測試函式，兩張 PR body **皆完全沒有**依規則寫「符合哪些准入條件」這一行。
+
+讀數：合格實例 2 個，admit 數（附准入條件記錄）= 0，alternative 數 = 0，**缺記錄
+數 = 2**。
+
+**判定**：這次不是「B 恆為 0 的三種情形分不清楚」（上次讀數已排除這個病灶），而是
+第三種、更根本的情形——**規則存在且無歧義，但執行者在動筆寫 PR body 的當下沒有
+意識到要查它**。純文字提醒（寫在 Step 2.5，PR body 是在後面的 Step 4 才組裝）在
+兩次連續合格實例上都沒有被觸發，證明「靠執行者記得回頭查一段前面讀過的規則」這個
+機制本身不可靠，不是這次剛好疏忽。
+
+**處置**：把 Step 4 的 PR body 樣板本身加一個 `Permanent test admissions:` 欄位
+（原樣板只有 `Refactor/reuse audit`／`Final verdict`／`Full suite` 等既有欄位，
+從缺永久測試這一項）。樣板本身是執行者組裝 PR body 時實際會複製的文字，欄位缺席
+會讓遺漏顯性化（要嘛填實際記錄、要嘛明寫 `none`），不必再依賴幾個段落之前那句
+散文提醒。新增對應回歸測試斷言樣板含這個欄位。A/B 讀數已可信（上次讀數已解決），
+故本票仍不結案的理由改變：現在是要觀察「樣板改結構之後，缺記錄事件是否消失」，
+而非「A/B 本身能否讀出訊號」。下次讀數起看第四欄——**樣板生效後的缺記錄次數**。
+
 **Non-goals**: 不設 `max_full_review_rounds` 輪數上限——與 `commands/ship.md`
 「round count 不是停止條件」直接衝突，且 [[CC-544]] 已證明放寬 gate 收斂條件會被
 qa-tester／risk-reviewer 連擋並全數 revert。減量要從 finding 端做，不是從輪數端。

+**The "Permanent test admissions" line is not optional filler** — Step 2.5
+required this record at the point each finding was remediated, and this
+template field exists so composing the PR body forces a check for it: a
+gate round with no finding whose remedy could have been a new permanent
+test gets `none`; every other round gets one line per such finding, whether
+it was admitted or resolved by a recorded alternative — `none` never stands
+in for an alternative-path finding's own record, and the citation is carried
+over from Step 2.5, not re-derived or skipped because that paragraph is
+several screens back by now.

 Do not merge. GO is not merge authorization — merge only when the user
 explicitly says so.
