 - CRMEB 客户端**任何异常都优雅降级**（返回空昵称/头像，不阻断登录），并 `logger.warning` 记录，便于排查。
 - `DEV_MODE=1` 才启用 `POST /api/auth/dev-login`，生产必须为 `0`。
 - **CRMEB 匹配口径**：openid 按 appid 隔离。若 CRMEB 与小程序非同一 appid，应改用 **unionid** 匹配（小程序传 unionid，CRMEB 内部接口按 unionid 查；openid 仍作本系统主键）。
+- **H5 端 openid 一致性检查**（分享场景必做）：当 H5 被其他用户分享的链接打开时，web-view 的 `localStorage` 可能残留原用户的 token。H5 的路由守卫（如 `ProtectedRoute`）必须比对**当前 URL 中的 openid** 与 **本地缓存 token 中的 openid**，不一致时清除缓存重新走登录流程：
+  ```tsx
+  const urlOpenid = new URLSearchParams(window.location.search).get('openid');
+  if (urlOpenid && token) {
+    const payload = decodeToken(token);
+    if (payload.openid !== urlOpenid) {
+      clearToken();   // 清除原用户缓存
+      return <Navigate to="/" replace />; // 重新登录
+    }
+  }
+  ```
+  > 否则会出现：B 打开 A 分享的链接，URL 中已是 B 的 openid，但 H5 读取到 A 的缓存 token，仍然展示 A 的数据。
