 # 权限视角预览
 
-授权账号登录后，直接访问 `/who` 搜索同一组织的有效用户，先核对角色与数据范围，再进入只读预览。常规页面不展示入口，未授权用户直接访问链接也无法使用。预览使用目标账号真实角色：BI-Leader/所有权限/数智中心为全量，BI-Leader-Dep为本部门，其余为本人负责；多角色时全量优先。保持各业务模块现有的范围规则，库存公共汇总等不会因此变为个人数据。
+授权账号登录后，直接访问 `/who` 搜索同一组织的有效用户，先核对角色与数据范围，再进入只读预览。常规页面不展示入口，未授权用户直接访问链接也无法使用。预览使用目标账号真实角色：BI-Leader/所有权限/数智中心为全量，BI-Leader-Dep为本部门，其余为本人负责；多角色时全量优先。资产库存（包括待交车、异动）对三类角色均展示全量，汇总、分组与车辆明细口径一致；所属公司筛选仍然生效。非库存资产及交还车历史维持部门/个人范围，公共库存权限不扩展历史业务访问。
