+## Browser Provider
+
+AiToEarn 的 Browser Provider 使用当前 Chrome 登录态，不把平台 Cookie、Token 或 CSRF 信息上传到服务端。当前已接入 CSDN、掘金、简书、知乎、今日头条、百家号、网易号、搜狐号、InfoQ、腾讯云开发者社区、阿里云开发者社区、思否、51CTO、开源中国和腾讯内容开放平台（企鹅号）：扩展读取平台稳定 UID，核对它与 AiToEarn 绑定账号一致后，在持久化发布任务中打开并填充编辑器。今日头条、百家号、网易号、搜狐号和 InfoQ 会将 Markdown 转为安全的富文本，保留标题、段落、列表、链接和图片。CSDN 只使用编辑器自带的签名请求客户端读取创作者资料，思否只从当前页面的 Next.js 会话数据读取 UID；网易号只接受创作者侧返回的 `wemediaId`，搜狐号只接受账号列表中的账号 ID，InfoQ 只接受用户接口返回的 UID，51CTO 只接受个人空间页面中可验证的稳定 UID，开源中国只接受官方账号接口返回的稳定 UID，企鹅号只接受页面中的稳定 `userID` / `userId`。
+
+扩展支持服务端随发布任务下发经过签名安装、Schema 校验并固化版本身份的声明式 Browser Provider 快照。插件只能覆盖核心十五个平台的标题、正文与第一层草稿/发布按钮定义；平台 URL、账号检测和最终结果判断仍由扩展核心维护。扩展会再次严格校验平台、选择器、编辑器类型、内容格式、源提交和内容哈希，写入后回读标题、正文长度和图片数量。配置漂移或回读失败时保留编辑器并返回明确失败，不执行仓库代码，也不会把未知按钮当作核心动作继续点击。
+
+Browser Provider 仅负责账号核对、编辑器填充和草稿/公开文章状态回读，不会自动点击最终公开发布按钮。所有已接入平台仍保留复制发布稿入口；未进入受控交接白名单的平台继续只支持手动复制，不会伪报“已同步”。
+
+扩展弹窗还保留公众号的单次人工确认填充入口，但不把它伪装成 Browser Provider。其他旧 COSE 选择器不会出现在扩展平台列表中，也不能通过桥接接口绕过能力白名单；仅有选择器或静态平台配置不代表平台已经接入。
+
+任务会复用已有编辑器标签页。标签页仍位于已保存草稿或公开文章时，扩展只返回并激活该标签页；如果标签页已离开任务页面，则在同一标签页重新进入编辑器并填充，不重复创建窗口。CSDN 只有 `blog.csdn.net/:author/article/details/:id`、掘金只有 `/post/:id`、简书只有 `/p/:id`、知乎只有 `zhuanlan.zhihu.com/p/:id`、今日头条只有 `www.toutiao.com/article/:id` 或 `www.toutiao.com/item/:id`、百家号只有 `baijiahao.baidu.com/s?id=:id`、网易号只有 `www.163.com/dy/article/:id.html`、搜狐号只有 `www.sohu.com/a/:id`、InfoQ 只有 `xie.infoq.cn/article/:id` 或 `www.infoq.cn/article/:id`、腾讯云只有 `cloud.tencent.com/developer/article/:id`、阿里云只有 `developer.aliyun.com/article/:id`、思否只有 `segmentfault.com/a/:id`、51CTO 只有 `blog.51cto.com/u_:uid/:id` 才记为已发布；带草稿标识的编辑器地址，以及网易号、搜狐号、InfoQ、51CTO 或开源中国页面明确提示草稿保存成功时才记为草稿。开源中国的公开文章 URL 尚未在真实创作者账号上验收，因此未知页面会进入“发布结果待确认”，不会伪报成功。
 
 扩展默认只打开并填充编辑器，不替用户点击公开发布。微信公众号保存草稿及任何平台的最终发布仍需用户明确确认。

 AiToEarn 后台触发浏览器采集时会优先复用同地址标签页；没有现成标签页时才在当前 Chrome 内创建后台标签页。普通采集完成后临时标签页会关闭，遇到登录、验证码或地区访问限制时则保留并激活页面，等待用户处理。
 
+当前互动桥接只开放受控白名单：能力查询、抖音账号核对、评论列表、回复列表和单条人工回复。作品 ID、评论 ID、账号 UID、回复内容、游标和数量均由扩展校验，网页不能向扩展传入任意请求地址。发送回复前必须由用户在 AiToEarn 界面逐条确认，扩展会再次核对当前浏览器账号与所选 AiToEarn 账号，写请求不会自动重试，也不支持批量回复、自动回复或私信。扩展优先复用当前 Chrome 中已有的抖音标签页，没有可复用标签页时才创建非激活标签页，并在抖音页面上下文内发起带现有 Cookie 的请求。
