+## 2026-06-01｜IwoooS S4.9 補件草稿詳情層落地
+
+**背景**：
+
+- S4.9 前台已能看到五張補件題目卡，但使用者仍需要知道每一題要填哪些欄位、不能做哪些事，以及為何尚未開啟執行閘門。
+- 本階段延續初期資安框架原則：只做可視化、read-only evidence 與人工 gate；不啟動 Kali 掃描、SSH 修復、主機更新、repo 變更或 runtime execution。
+
+**本次調整**：
+
+- `apps/web/src/app/[locale]/iwooos/page.tsx`：
+  - 新增 `IwoooSS49RequestDraftDetailBoard`，把 D1-D5 拆成五列詳情層。
+  - 每列顯示必要欄位 `6 欄`、禁止事項 `10 禁`、證據格式 `脫敏 refs`，並維持 `待負責人確認`。
+  - 邊界顯示 `request_sent=false`、`owner_response_received_count=0`、`owner_response_accepted_count=0`、`secret_plaintext_collection_allowed=false`、`active_runtime_gate_count=0`。
+- `apps/web/messages/zh-TW.json` / `en.json`：
+  - 新增 `iwooos.s49RequestDraftDetail` 文案；英文語系維持繁中文案鏡像。
+- `docs/security/iwooos-posture-projection.snapshot.json`：
+  - 新增 `s4_9_request_draft_detail_*` summary 與五筆詳情列機器證據。
+  - 鎖定 `required_field_count=6`、`forbidden_action_count=10`、`redacted_evidence_refs_only=true`、`runtime_execution_authorized=false`。
+- `docs/security/gitea-inventory-owner-attestation-request-draft.snapshot.json`：
+  - 新增 `frontstage_detail_visible=true`、`frontstage_detail_row_count=5`、`frontstage_required_field_total=30`、`frontstage_forbidden_action_count=10`。
+- `docs/security/security-mirror-status-rollup.snapshot.json`：
+  - 新增 S2.161 台帳，標記這是 framework detail，不是 headline percent 或 runtime delta。
+- `scripts/security/security-mirror-progress-guard.py`：
+  - 新增 S4.9 詳情層 guard，防止詳情列被誤讀成已送出、已收件、已接受、已審批、已收機密或已開執行期 gate。

+  - Mobile `390x844`：S4.9 詳情層存在、五列題目存在、必要邊界字串存在、內部對話語氣不存在、horizontal overflow `0`。
+
+**目前整體進度（本階段完成後）**：
+
+- 完整 IwoooS / 資安網總進度：維持 `61%`；本階段讓 S4.9 補件草稿更可執行，但仍未收到負責人回覆。
+- 框架 / 治理 / 文件 / schema / read-only evidence：約 `86-88%`；S4.9 題目、欄位、禁區與證據格式已能被前台、snapshot 與 guard 同步看見。
+- Runtime ingestion / GitHub primary / AwoooP production landing：約 `40-45%`；`request_sent_count=0`、`owner_response_received_count=0`、`owner_response_accepted_count=0`、`active_runtime_gate_count=0`。
+- Kali `192.168.0.112` 與開發主機 `192.168.0.111` / `192.168.0.168` 仍維持已納入框架、未啟動掃描 / 修復 / 更新 / 重啟的邊界。
