+   保留现有配置其他字段，再让 Runner 加载更新后的配置。Mac App 内置节点会在配套服务更新重启后使用原加密配置；仅更新另一台客户端，不能更新服务器上的旧进程。`computers` 与 `browser` 可分别配置，单独启用浏览器不要求 VM Worker。`maxSessions` 范围 1–8，默认 3；空闲回收范围 60 秒–2 小时，默认 5 分钟。
 
 2. 管理员在 Bot 工具设置中打开“托管浏览器”。Bot 的来源与 Profile 必须在 Runner 和账号权限范围内，Hermes 本轮工具桥也必须可用。
 3. Bot 首次调用打开浏览器，或用户在聊天卡片/电脑面板点击“接管浏览器”时，节点检查配套 Chromium 和沙箱启动。缺少环境时自动安装并显示阶段与当前组件的下载进度，完成后继续打开同一浏览器。单纯查看状态不会下载安装。
 
 ## 环境自动准备
 
-浏览器二进制按需下载，不随应用包分发。开启浏览器的节点即使尚未安装 Chromium，也会声明“可准备”能力；界面区分未安装、检查中、安装中、就绪和失败。安装使用应用锁定版本的 Playwright CLI，不调用另一版本的全局命令。一次节点安装由多个已授权使用者共享；断线、关闭节点或所有安装授权失效会取消安装，不会取消其他仍有授权的使用者。
+浏览器二进制按需下载，不随应用包分发。开启浏览器的节点即使尚未安装 Chromium，也会声明“可准备”能力；界面区分未安装、检查中、安装中、就绪和失败，并分别说明节点未连接、版本过旧或管理员明确关闭。可点击“重新检测”刷新节点状态；此操作只检查，不下载安装。安装使用应用锁定版本的 Playwright CLI，不调用另一版本的全局命令。一次节点安装由多个已授权使用者共享；断线、关闭节点或所有安装授权失效会取消安装，不会取消其他仍有授权的使用者。
 
 安装完成前必须通过真实的 Chromium 沙箱启动检查。Linux 缺少系统依赖时，仅在节点已经以 root 运行的情况下调用配套 `install-deps chromium`；普通账号会得到明确依赖提示，需要管理员先补齐系统依赖。安装过程不自动提权，不添加 `--no-sandbox`。生产 Runner 应以支持沙箱的非 root 账号运行。失败保留原因，由“重试并接管浏览器”明确发起下一次安装；不会无限重复下载安装。
