+托管浏览器由现有 Runner 按需启动专用 Chromium 进程，通过原来的节点鉴权、任务租约和结果通道工作。网页任务可以直接使用浏览器；需要 Linux 程序、终端或完整桌面时，继续使用现有 VM。Hermes 仍负责模型、会话和技能。
+
+这是独立浏览器进程，不是新增 Linux 虚拟机或 Docker 浏览器服务。Web 与 macOS 电脑面板提供查看和人工接管，窄屏 Web 可用；本次没有新增 iOS/Android 原生浏览器界面，也没有替换现有 UI 技术栈。

+默认关闭。升级代码不会自动启动 Chromium，也不会改变已有 Bot 的虚拟机、云电脑或本机电脑设置。
+
+1. 在运行 Runner 的同一系统账号下安装配套 Chromium。源码运行执行：
+
+   ```sh
+   npm ci
+   npx playwright install chromium
+   ```
+
+   独立 Runner 分发包需复制整个 `.runner-build/` 目录，再在目标主机执行：

+   ```
+
+   Linux 还需安装 Chromium 的系统依赖，可用对应 CLI 的 `install-deps chromium`。Chromium 启用自身沙箱；用非 root 账号运行 Runner，不添加 `--no-sandbox`。浏览器二进制、登录资料和缓存不随程序包分发。没有安装配套二进制的节点不会声明浏览器可用。
+
+2. 在执行节点配置中启用“托管浏览器”，或给现有 `runner.json` 添加：
+
+   ```json
+   {
+     "browser": {
+       "enabled": true,
+       "maxSessions": 3,
+       "idleTimeoutMs": 300000
+     }
+   }
+   ```
+
+   保留现有配置其他字段，再让 Runner 加载更新后的配置。`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。
+
+3. 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。
+4. 在 Bot 电脑面板选择“托管浏览器”。任务按需打开；人工点击接管也可打开，单纯查看状态不会启动 Chromium。
+
+## 会话与接管
+
+- 普通 Bot 的 Chromium 资料按账号和 Bot 隔离，保存在 Runner 数据目录的 `managed-browser/profiles/`，关闭页面后保留登录资料。临时助手使用临时资料，关闭后删除。
+- Bot 浏览器与本机浏览器、VM 内浏览器不共享 Cookie、页面或资料目录。一个 Bot 的资料同时只允许一个进程写入。
+- 人工接管与 Agent 使用同一个 Chromium 上下文。接管先等待当前操作收束并切换控制代次；Agent 的后续浏览器调用等待交还。交还后模型获得备注，并重新读取网页。
+- 人工控制凭据有效期 30 秒，由控制页面持续续期；失效后拒绝旧输入，不自动让 Agent 恢复操作。多页面查看不会使控制者的近期画面失效；输入请求按编号去重，动作完成后旧画面不可再次用于新输入。
+- 任务结束时关闭浏览器；人工仍持有控制权时保留到交还。任务完成前应导出所需下载，关闭会清理临时下载。持久资料继续保留。
+- 断线、撤权、节点/Profile 改变会使旧授权失效。切换执行来源时，新来源先确认关闭遗留上下文再操作；不同节点之间不自动搬运登录资料。
+
+## 工具与文件
+
+工具使用独立的 `managed_browser_*` 前缀：打开、状态、DOM 快照、页面操作、附件上传、下载导出。页面操作支持导航、标签页、点击、填写、键盘、滚动和截图。普通网页先使用 DOM 快照与元素引用，确有视觉需求时再截图。
+
+下载先取得 `downloadId`，通过 `managed_browser_export` 作为现有对话附件交付。上传使用当前账号有权访问的附件 `fileId`，模型不传宿主文件路径。单文件上限 25 MiB。
+
+同一轮已授权 VM 时，额外提供 `managed_browser_to_vm` 与 `managed_browser_upload_vm`。复制使用现有 VM 分块文件协议、摘要校验和路径边界；默认不覆盖文件，也不挂载宿主目录。跨环境文件还受全局文件传输大小设置约束。
+
+网页网络请求走经鉴权的公网代理，拒绝回环、私网与重新解析到私网的目的地址；既有连接也定期检查授权。当前禁用 Service Worker 和 WebSocket，因此依赖这些功能的网站可能不完整。DOM 元素快照目前针对主页面；拖拽等高级输入尚未接入。浏览器不支持通过任意 JavaScript、CDP 或宿主命令接口绕过这些边界。
+
+## 与已有功能的兼容
+
+- 未启用时不会给 Hermes 增加浏览器工具，也不改变原电脑后端选择；旧客户端保存工具配置会保留新增开关。
+- 原 `computer_*`、`desktop_*`、`cloud_computer_*` 工具继续走自己的执行路径。浏览器不可用时不会隐式切换环境重做。
+- 共享 VM 中取消一个 holder，只取消该 holder 的命令。Container 和 Compose 均按操作编号取消进程组，其他 holder 的任务继续运行。
+- 工具操作保存意图和有界回执；相同调用编号不会再次执行已提交操作。不确定结果要求先核对，不能盲目重放。
+- Container 命令取消无需更换 VM 镜像；Compose 桌面需同步发布更新后的 `deploy/computer/compose_bridge.py`（含 `cancel` 协议）。升级 Compose 时先结束运行任务，再按原部署流程更新桌面镜像；不要只更新 Runner 而保留旧 bridge。
+- 回退功能时关闭全局开关和 Runner 的 `browser.enabled`，保留资料目录即可。已有 VM、文件库和 Hermes 配置无需迁移。
+
+## 验证
+
+常规检查：
+
+```sh
+npm run typecheck
+npm run build
+NODE_OPTIONS=--no-experimental-webstorage npm test -- --maxWorkers=4
+```
+
+本地 Node 26 的实验性 Web Storage 会覆盖测试环境的 `localStorage`，因此全量测试使用上述选项。
+
+macOS 桌面回归需先生成本地桌面运行包与原生 helper：
+
+```sh
+npm run desktop:build
+npm run desktop:test
+```
+
+真实 Chromium 验收（先安装配套浏览器）：
+
+```sh
+YAOYAO_BROWSER_SMOKE=1 npx vitest run tests/runner/browserSmoke.test.ts tests/server/managedBrowserSmoke.test.ts
+```
+
+这两项覆盖真实页面操作、上传下载、登录资料恢复，以及 HTTP Runner 领取/准入/结果/授权检查、无 VM 浏览器握手、人工接管与交还。HTTP 测试使用 Hermes fixture，不代表真实模型自主选择工具的评测。macOS Chromium 和临时 Docker 命令取消已实测；Linux Chromium 沙箱与 Windows 安装仍需目标平台验证，尚无与完整 VM 的性能基准数字。
