+# 企业公共语言主控台与第五域桥接回执
+
+`REPO-016` 已正式分配给“冰朔企业公共语言主控台”：`bingshuo/guanghu-language-master-work`。
+
+光湖团队从各自 HoloLake 个人频道进入企业身份登录页，再进入各自责任仓；他们不是登录服务器操作系统。五位当前负责人账号已换成一次性临时密码，服务器数据库逐一读回“首次登录必须改密”。密码仅保存在冰朔本机权限 `0600` 的交付文件中，不进入代码仓库、回执或对话。
+
+冰朔从 `JD-FD-PRIMARY / ICE-CH-ZC001` 使用 `FD-BRIDGE-ENTERPRISE-LANGUAGE-MASTER-0001` 进入 `REPO-016`。桥接凭据只保存在京东节点 root 可读的 `0600` 文件里；推送仍必须校验干净 `main`、预期远端 SHA、目标读回和回执。
+
+旧 `bingshuo/hololake-world` 含已退役纪元与旧职责，只保留历史，不作为当前公共语言主控台。
