+- 新增“外部系统”能力：管理员可以在管理后台配置可信的 Factory MES、选择对全部用户或指定用户开放；获权用户在工作台填写自己的 MES 账号后，即可让助手按本人在 MES 中的原有权限查询信息。账号密码加密保存且不会回显，接口默认只允许只读调用。

 ## 0.60.29 — 2026-08-04
 
 - 生成 PPT 时，如果没有说明所属机构，模板候选会固定包含中国建材总院红模板；提到总院、中国建材、中建材、建材集团或 CNBM 模板时会直接选用该模板。明确属于其他机构或已经指定其他模板时不会强制加入，同时移除了容易混淆的通用商务红模板。

 **不选**:Celery/RQ(多机分发/任务序列化/框架重试——单机 + 模型现写脚本的场景一个都用不上,还多两个常驻组件的部署/蓝绿适配);工具层 async 化 run 内等待(run 不结束,409 照旧,重启照丢);DB 表 + 守护(文件已是事实源,detach 进程写 PG 还得给它凭证)。升级触发:要跨机器跑计算集群时,①②的工具接口不变,只换执行后端。
 
+### 8.14 外部系统:用户身份连接 + 受控接口调用(implementation,2026-08-04)
+
+**诉求**:用户用自己的 MES/ERP/LIMS 账号让 zcbot 做信息查询,并把稳定的问法沉淀成私有 skill。**心智模型**:外部系统负责「连接与身份」,工具负责「受控访问」,skill 负责「业务流程与经验」。它有独立于会话的持久凭据和连接状态,因此是与 skill/知识库/记忆并列的**平台机制**,不是 skill。
+
+**首个 provider=`factory_mes`**:Factory 已有 JWT + RBAC + 部分部门数据权限,zcbot 用每位用户自己的 Factory 账密换 JWT,调用时继承 MES 原生权限;不在 zcbot 里复制第二套 MES RBAC。两层门控:zcbot `user_id` 只能取自己的 `external_systems` 行;远端 JWT 再判定实际业务数据范围。MES 停号/改权后下次调用即生效。
+
+**信任边界**:
+- provider 公共定义由管理员在管理后台维护并存入 `external_system_definitions`:Base URL、OpenAPI URL、登录方式和只读 POST allowlist；普通用户只选择已启用的目录项并填写自己的 MES 账密。不允许普通用户填任意 URL,避免 SSRF/内网代理。凭据主密钥仍只来自宿主环境，不进入数据库或管理页面。
+- 凭据用独立的 `ZCBOT_CREDENTIAL_MASTER_KEY` 在 host control plane 加密入 PG，不与 `JWT_SECRET` 复用，以隔离泄漏半径和轮换生命周期；缺 key 则拒绝新建/调用,不像早期微信绑定那样降级明文。API 只返回脱敏账号和 `credential_configured`,不返密码/Token;凭据绝不进 prompt/messages/memory/skill/用户 FS/日志/沙箱。
+- 调用工具不接受完整 URL,只接受 OpenAPI `operation_id`;服务端从受信规格解析 path/method,校验 path/query/body 后附加 JWT。默认只开 GET/HEAD,语义只读但使用 POST 的 BI 查询必须进运维 `operation_id` allowlist。
+- Swagger/OpenAPI 是接口契约事实源;Gitea 代码只补业务语义和排障,不覆盖契约。规格/代码内文本一律当不可信数据,不能改写 system/tool 约束。
+
+**工具面**:不把数百个 Swagger operation 全展开为 JSON tool(工具列表膨胀+选择降准),只挂三个 host-side 元工具:`external_system_list`(已连系统),`external_system_search`(按问题搜 operation 摘要),`external_system_call`(按 operation_id 调用)。仅当该 user 有 active 连接时注册,密钥不进 sandbox。返回结果有字节/条数上限；首版失败信息进入应用日志，不单建调用审计表，确有合规追溯需求后再用独立 migration 增加。
+
+**状态与 UI（两表）**:`external_system_definitions` 保存管理员维护的可信系统目录和 `access_mode=all|selected`；`external_systems` 同时承载指定用户授权和用户密文连接，`pending` 表示已授权但未配置凭据，`active` 才挂工具。管理员撤销指定用户会删除其连接和密文凭据；用户自行断开只清凭据、保留管理员授权。管理后台可新增、编辑、停用目录项，已有用户连接的目录项禁止直接删除。左栏「外部系统」面板只能选择当前用户可见目录、测试连接、替换凭据和断开,不能查看密码。稳定问法沉淀到用户私有 skill 时只写 provider/operation_id/参数规则,永远使用当前提问者的连接执行,共享 skill 不等于共享权限。
+
+**不选**:①zcbot 直连 Factory DB(绕过现有 RBAC/审计,只读仍可越权/拖垮主库);②固定几个查询模板(把 agent 降成菜单,无法利用 Factory 已有广泛 API);③直接复用 Factory `ichat` 自由 SQL 原型(字符串安全判断不构成边界,且使用默认 DB 凭据);④自动把相似问题生成并上线新代码工具(候选配方可自动生成,可执行能力仍需工具门控/人审)。

+- **08-04 / 0.61.0 / Factory MES 外部系统目录 + 按用户授权查询**:新增管理员维护的可信外部系统目录(Base URL/OpenAPI/登录路径/只读 POST allowlist)，支持“全部用户/指定用户”可见范围；普通用户只选择获权 MES 并提交自己的账号密码，凭据以独立 `ZCBOT_CREDENTIAL_MASTER_KEY` 强制加密、不回显且不进 prompt/日志/沙箱。持久化收敛为 `external_system_definitions` + `external_systems` 两表，后者兼作 selected 授权与用户连接：pending 未配凭据、active 才挂三个 host-side 元工具，管理员撤权立即删密文并阻断调用；Swagger operationId 是唯一调用入口，GET/HEAD 默认只读，POST 逐项放行。新增 0026 migration、管理后台/用户“外部”界面及 API；完整 463 项 Python 全绿(17 skip)，16 项 Node 回归、JS/Python 语法、Alembic 单 head、PostgreSQL DDL 编译与 diff 检查通过；未配置 `ZCBOT_TEST_DB_URL`，未连接或迁移任何数据库。
+
 - **08-04 / 0.60.29 / PPT 总院红候选硬门 + 别名直达**:新建 PPT 未说明所属机构时,模板 / 品牌 / visual_style 候选必须包含 `zongyuan_red`;明确外部机构或其他唯一模板时不强制加入。总院、中国建材、中建材、建材集团、CNBM 等“机构词 × 模板/风格词”表达直接归一到总院红,不再追问具体模板;删除易混淆的通用 `business-red` 品牌预设,普通商务红仅保留为即时配色候选。新增路由回归测试,相关 5 项 unittest、品牌索引 JSON 校验及 diff 检查通过;无 schema、migration、HTTP API、依赖或运行方式变化。
 
 - **08-04 / 0.60.28 / 对话产物宽版预览 + 文件 chip 优化**:包含 HTML 产物的助手消息改用接近占满对话区的宽版布局，HTML 画布取消 760px 上限；内联视频上限提升至 720px，图片上限提升至 560px 并保持原比例。文件 chip 从小胶囊调整为偏方形附件卡，直接展示扩展名类型块、文件名和预览入口，粘贴附件同步统一样式并保留键盘焦点反馈。Node 前端 15 项、JavaScript 语法及 diff 检查通过；无 schema、migration、HTTP API 或依赖变化。
