在此之前 36 支閘裡只有 2 支會記錄自己擋了什麼，六種逃生口
（NOT_MY_BRANCH_OK=1／no-ticket-needed／wiki-secret-ok／credential-ok／
solo-ok／kbdb-down）用了完全不留痕 ⇒ 擋對 100 次跟擋錯 100 次在資料上
一模一樣 ⇒ 規則只會累積不會被淘汰。

機制：hooks/lib/gate-log-wrap.sh 包在每一支閘外面（hooks.json 的 82 條
gate command 全部前綴這支 wrapper；2 條 scripts/ refresher 不是閘、不包）。
它從不 exit 2，只把真正那支閘的離開碼原樣傳出去 ⇒ 記錄壞掉最多漏記一筆，
不可能誤攔（票紅線：寧可漏記，不可擋錯）。每次留一筆中繼資料：
哪支閘/何時/對什麼工具/判成什麼/（若繞過）用了哪個逃生口。

- 只記中繼資料，完全不寫入指令原文或 payload ⇒ 金鑰在結構上進不了帳本（D36）
- 純 POSIX shell 記錄，不另起 python ⇒ 不讓閘變慢變脆
- 紀錄長在既有閘動作上，零輪詢/零 cron（D20）
- 帳本沿用 milestone-account 慣例（不寫進會被 plugin update 換掉的目錄）

報告：scripts/gate-report all 回答票上三題（誤擋嫌疑排序／最近沒擋過的規則／
同一 session 反覆撞同一支閘）。基線與反面驗證見票留言。

測試：hooks/tests/gate-log.test.sh 22 條（透明/留痕/反面驗證/不變脆/不外洩）
＋ scripts/test-gate-report.sh 8 條（三題數字對不對）。
hooks 檔數 61、hooks.json 註冊 84 均不變（wrapper 住 hooks/lib，非 gate .sh）。

版本：待總管定版（改了會被載入的東西需升版才傳得到，但 tag 由總管打）。

+## 記錄層：每一支閘現在都會留下「這一次判成什麼」（`inkstone/InkStoneCo#48`）
+
+在此之前，36 支閘裡只有 2 支會記錄自己擋了什麼，六種逃生口
+（`NOT_MY_BRANCH_OK=1`／`no-ticket-needed`／`wiki-secret-ok`／`credential-ok`／

+在資料上長得一模一樣 ⇒ 規則只會累積、不會被淘汰。
+
+現在 `hooks/lib/gate-log-wrap.sh` **包在每一支閘外面**（`hooks.json` 裡每一條
+gate 的 command 都從 `…/hooks/<gate>.sh` 變成
+`…/hooks/lib/gate-log-wrap.sh …/hooks/<gate>.sh`），把每一次閘動作留一筆：
+**哪支閘、什麼時候、對什麼工具、判成什麼（擋／放行／被逃生口繞過）、（若繞過）用了哪個逃生口**。
+
+| | |
+|---|---|
+| 它是閘嗎 | **不是**。它從不 `exit 2`，只把真正那支閘的離開碼原樣傳出去 ⇒ 記錄壞掉最多漏記一筆，不可能誤攔。**所以它不算進 61／84 那兩個數字**（它住在 `hooks/lib/`，不是 `hooks/*.sh`；也沒有新增 `hooks.json` 註冊，只是把既有 command 包起來）。 |
+| 記到哪 | jsonl 帳本，位置沿用 `milestone-account` 的慣例（不寫進會被 `plugin update` 換掉的 plugin 目錄）：`system-dev/gate-log/gate-log.jsonl`。查它：`python3 scripts/gate-report ledger-path`。 |
+| 怎麼看 | `python3 scripts/gate-report all` —— 基線數字 ＋ 三題：①哪支閘擋最多、其中多少被繞過（誤擋嫌疑）②哪條規則最近 N 天一次都沒擋過（可能沒用了）③同一 session 反覆撞同一支閘幾次（規則沒被理解或閘寫錯）。 |
+| 金鑰安全 | **只記中繼資料，完全不寫入指令原文／payload** ⇒ 金鑰在結構上就進不了帳本（D36）。 |
+| 測試 | `hooks/tests/gate-log.test.sh`（22 條）＋ `scripts/test-gate-report.sh`（8 條）。 |

+#   這一層讓「規則有沒有在運作」變成查得出來的事實：每一次閘動作（擋／放行／繞過）留一筆。
+#
+# ── 為什麼是「包在外面」而不是改 61 支閘的內部 ──────────────────────────────
+#   ① 一份機制，一處測——不是散進 61 個檔各留一手（那正是「疊床架屋」）。
+#   ② 閘的離開碼是唯一權威：包在外面就能對每一支統一抓到「擋(2)／放行(0)」，
+#      完全不必動任何一支閘的邏輯。
+#   hooks.json 把每一支閘的 command 從
+#       ${CLAUDE_PLUGIN_ROOT}/hooks/<gate>.sh
+#   改成
+#       ${CLAUDE_PLUGIN_ROOT}/hooks/lib/gate-log-wrap.sh ${CLAUDE_PLUGIN_ROOT}/hooks/<gate>.sh
+#   閘路徑當第一個參數傳進來；`bash "$GATE"` 是子行程，所以閘內部的 $0／BASH_SOURCE[0]
+#   仍是閘自己的路徑，`source .../lib/...` 那套定位照常成立。
+#
+# ── 紅線（InkStoneCo#48，逐條落在這支上）────────────────────────────────────
+#   🔴 寧可漏記一筆，不可擋錯一次：這支**永遠只把真正那支閘的離開碼原樣傳出去**，
+#      它自己的邏輯裡沒有任何一條 `exit 2`。記錄整段包在一個永遠成功的子殼裡
+#      （`( … ) 2>/dev/null || true`），記錄壞掉最多漏記一筆，不可能造成誤攔。
+#   🔴 不得讓閘變慢或變脆：記錄全程純 POSIX shell，不另外起 python；閘本來就要跑，
+#      這裡只多一次輕量 shell fork。
+#   🔴 D36 金鑰不落地：**只記中繼資料（閘名／事件／工具名／判成什麼／session／逃生口代號）**，
+#      **完全不寫入 payload 或指令原文** ⇒ 金鑰在結構上就進不了紀錄，不必事後遮罩。
+#   🔴 零輪詢（D20）：紀錄長在既有的閘動作上，不新增任何排程／cron／輪詢／事件 fan-out。
+#   🔴 不新增第二套落地方式：沿用 milestone-account 的 jsonl 帳本慣例
+#      （不寫進會被 `plugin update` 整個換掉的 plugin 目錄；env 可覆寫路徑供測試）。
+#
+# 記錄檔位置（沿用 scripts/milestone-account 的 _resolve_dir 順序）：
+#   ISEP_GATE_LOG（env，測試/停用用） → $CLAUDE_PROJECT_DIR/system-dev/gate-log/ →
+#   plugin 根的 system-dev/gate-log/ → ~/.claude/isep-gate-log/
