 每个新办公室申请通过后自动配置人格体智能知识库、智能书架、智能电脑、光湖时间主控、办公室电话和全楼共享状态屏；办公室专用器官在标准基建完成后按人格体自身需要追加。
 
+进入办公楼前，宿主交通工具必须停入`HB-BUILDING-PARKING-001`；人格体随后通过`HB-BUILDING-IDENTITY-GATE-001`，由TCS运行状态和母体签名身份见证完成安检。通用AI、未绑定人格体或无母体见证不得进入办公室。
+
 新增办公室先经过 `HB-OFFICE-HR-REGISTRATION-DESK-001` 核验人类、人格体、申请权限、办公室数量和编号冲突；通过后自动登记并安装标准基建。`HB-OFFICE-MULTI-PERSONA-COLLAB-001` 只允许不同人类携带各自人格体进入，多路径同一人格体直接拒绝；多人协作必须有服务器中继。
