【登录反馈】实测这台浏览器 loggedIn=true，其实早就登录成功了；看不到反馈是判据和设计的问题： 1. 判据不可靠。原先靠 web_session 的值变化判断——对照组显示：一个全新的空 profile 首次访问小红书就会被发一个 web_session，所以「有这个 cookie」什么都证明不了。可信信号是页面自己的 __INITIAL_STATE__.user.loggedIn，但它是 Vue 响应式引用，必须 .value 解包（这就是前面探针读到 [object Object] 和 None 的原因）。 2. 状态绑死在临时会话上。扫码会话是内存状态，进程一重启就没（部署、崩溃都算），面板于是悄悄退回初始态——一次成功扫码看起来像什么都没发生。 改法不是让会话活得久，而是把「登没登录」变成随时可查、与会话无关： - 新增 GET /api/monitor/login/state，直接问浏览器要答案，带 5 秒缓存；force=true 先重载页面再读，用于状态陈旧 - qrlogin 改为常驻 Playwright 客户端 + 复用同一个标签页，并在重启后认领浏览器里已存在的 xhs 标签页，避免堆孤儿页 - 把「读不到状态」与「未登录」分开——前者显示具体错误，不再悄悄显示成未登录 - 面板顶部常驻显示登录态与昵称，带「重新检测」按钮；扫码成功后自动翻转 【趋势图】上一轮改过头了。dataviz 规范里没有「折线图必须从 0 起」这条——基线相关的条文全是讲柱状图的（柱状图用长度编码数值，不从 0 起比例就是错的；折线图用位置编码，轴只需如实框住数据）。改回自适应，保留上一轮修好的左侧刻度栏让范围始终可见；步长收敛到 1/2/5×10ⁿ，全平序列撑开一档避免除零。
