+## 2026-06-11｜P2-402F AI Agent host / K3s / stateful 版本只讀盤點
+
+**背景**：P2-402E 已建立 Gitea PR 草案 lane，但 host OS、K3s、PostgreSQL、Redis、MinIO、Harbor、Gitea 與監控 / DevOps stateful 服務仍缺少統一版本盤點與 maintenance window 批准包。本階段先建立 committed read-only inventory，讓 OpenClaw / Hermes / NemoTron 可以整理版本與維護證據，但不得執行 SSH、kubectl、升級、重啟或 Telegram 實發。
+
+**本輪完成**：
+
+- 新增 `docs/schemas/ai_agent_host_stateful_version_inventory_v1.schema.json`。
+- 新增 `docs/evaluations/ai_agent_host_stateful_version_inventory_2026-06-11.json`：5 台主機、2 個 K3s 節點、12 個 stateful / ops 服務、6 個只讀 probe step、11 個 maintenance window 必填欄位。
+- 新增 `apps/api/src/services/ai_agent_host_stateful_version_inventory.py`，強制驗證 SSH / kubectl / apt upgrade / K3s upgrade / node drain / reboot / stateful restart / Telegram direct send / conversation transcript 全部 false。
+- 新增 `GET /api/v1/agents/agent-host-stateful-version-inventory`。
+- 新增 loader / API 測試，覆蓋 SSH boundary、rollup consistency、host reboot、K3s drain、stateful restart、maintenance package 欄位與工作視窗內容 redaction。
+- 更新 `ai_agent_proactive_operations_contract_2026-06-11.json`：整體完成度 `86%`，current task `P2-402F`，next task `P2-402G`。
+- 同步 `AI_AGENT_AUTOMATION_WORKLIST_2026-06-04.md`、`AI_AGENT_PROACTIVE_OPERATIONS_2026-06-11.md`、P2-402C/D/E 報告與 MASTER §3.2.1c / §5 / changelog。
+
+**完成度同步**：
+
+- P2-402F：`100%`。
+- AI Agent 主動營運委派與版本生命週期：`86%`。
+- Current task：`P2-402F`。
+- Next task：`P2-402G` governance UI 顯示可委派能力。
+
+**邊界**：
+
+- 本波仍不 SSH、不執行 host command、不執行 kubectl、不 apt / kernel / K3s upgrade、不 node drain、不 kubelet restart、不 reboot、不 stateful restart、不 DB migration、不 restore、不 pull image、不發 Telegram、不讀取或輸出 secret、不回傳工作視窗對話內容。
+
 ## 2026-06-11｜P0 Telegram no-action 人工處置包
 
 **背景**：使用者再次指出 Telegram 告警即使已改成 `NO_ACTION - REPAIR_CANDIDATE_MISSING`，卡片仍只說「AI 選擇不執行修復，需要人工判斷」，但沒有產出可操作的人工處置選項、證據補齊清單、修復候選建立方式或後續驗證說明。這代表前一輪只止住 fake execution，尚未把 no-action / 需人工路徑變成可接手的處置包。
