 最多 256 项，每个 ID 最多 256 字节；重复 ID 去重，不接受空白、控制字符、`__` 前缀或 `*` 通配符。
 允许保存当前上游目录尚未返回的 ID。限制按全局模型映射后的上游 ID 判断，不扩大账号本身的上游权限。
+管理端刷新目录只更新目录，不修改模型限制。白名单的清理按钮列出当前目录未返回的已选 ID，默认不选中任何项，
+由管理员确认后从当前表单移除，保存账号后生效。目录未就绪、刷新失败或返回空目录时不能清理，清理也不能将白名单置空。
+图像、搜索、插件适配模型和映射目标可能不在目录中，目录缺失本身不代表模型失效。
 例如 Plus 设置 `allowlist` 并选中 luna 的实际 ID，Pro 设置 `denylist` 并选中同一 ID，即可严格分流；
 Pro 使用 `all` 时也能参与 luna 调度。套餐名称不自动生成或修改规则
