+## 流水线权限
+
+**是什么**：按流水线控制「谁能看、谁能发布、谁能改」。未被授权的普通用户看不到任何流水线与发布记录（默认拒绝）；管理员始终拥有全部权限。
+
+**三级权限**：
+
+| 等级 | 能做什么 |
+|---|---|
+| 查看 | 看流水线、发布记录、发布成功/失败日志（只读，不能构建） |
+| 发布 | 查看 + 触发构建、批量发布、失败重试 |
+| 管理 | 发布 + 编辑流水线配置、管理该流水线的成员授权 |
+
+**怎么授权（管理员，系统 → 流水线权限）**：
+- 新建权限组 → **选择流水线**：直接勾选要授权的流水线（推荐，全程点选）
+- 或 **名称匹配（高级）**：只写 `cex-*` 这类通配符（`*` 代表任意字符，无需正则），一次授权整批，之后新建的同名流水线自动纳入
+- 选好权限等级，勾选成员，保存即生效
+- 也可以在单条流水线里：编辑器顶栏「成员」按钮，给个别人单独授权（作为权限组的例外补充）
+
+**普通用户能看什么**：
+- 菜单只剩「发布」组（流水线/批量发布/发布记录）和「文档中心」；资源、集成、GitOps、系统管理类菜单全部隐藏（直接输 URL 也会被拦回）
+- 流水线列表只显示被授权的；按钮按等级显隐：查看级只有只读入口，发布级出现「执行/保存并运行/重试」，管理级才有「保存/成员」
+- 新建/删除流水线、凭证/主机/集群/构建节点等资源管理仅管理员
+
+**技巧**：
+- AI 助手批量发布同样受控：对未授权的 Job 会在结果里明确标注「无该流水线的执行权限」
+- 构建日志 SSE 已要求登录（`?token=` 传递会话），未登录直接访问返回 401
+
 ## 常见问题
 
 **初始密码在哪**：服务器 `data/initial-admin-password.txt` 或 `grep -A6 "已生成管理员账号" logs/flowstack.log`
