+开启后，访客先完成浏览器原生账号密码验证，再进入原有 ARTEX 登录页。网页、静态资源和 API 均受保护，`/api/health` 的 GET/HEAD 健康检查同样需要通过 Basic Auth，未认证时返回 `401`；通过后仅返回 `{"ok":true}`，不暴露应用名称或版本。健康检查不额外要求管理员 JWT；外部探针需要配置相同的 Basic Auth 凭据，例如使用 `curl --fail --user '验证用户名' http://127.0.0.1:8787/api/health` 并按提示输入密码。未启用 Basic Auth 时保留原有的无需凭据探活行为。版本号由需要管理员 JWT 的 `/api/version` 提供，启用访问验证后该接口同时受 Basic Auth 保护。未认证请求的 Basic Auth realm 使用通用名称 `Restricted`；通过访问验证仍需登录 ARTEX 才能使用业务 API。公网部署请通过 HTTPS 访问。
+
+从仍使用 `/api/health` 读取版本的旧版网页升级到此版本时，旧页面可能无法自动判断升级完成；服务重启后手动刷新页面即可。新版网页的版本显示和升级轮询均使用 `/api/version`。
 
 配置持久化到数据库，密码仅保存 bcrypt 哈希，界面不会回显。保存时密码留空表示不修改；关闭后保留凭据，方便再次开启。独立的 HttpOnly 验证 Cookie 有效期为 12 小时，兼容现有 JWT 和 SSE；保存配置会使其他浏览器的旧验证 Cookie 失效，当前管理员浏览器保持访问。浏览器可能缓存 Basic Auth 凭据，可用新的无痕窗口检查验证弹窗。
