  "status": "SERVICE_UPDATE_PACKAGE_READY · DEPLOYMENT_PENDING",
  "purpose": {
    "what": "更新已在线的光湖 AI 发现服务，使公开只读入口加载完整第五域仓库、节点、主体与旧编号别名地图。",
    "why": "代码频道已经把铸渊规范编号统一为 ICE-P-ZY001，但京东主节点仍运行旧服务，旧编号无法自动导航到规范编号，仓库事实尚未进入现实运行层。",
    "success": "公开入口可读取主体注册表，并将 ICE-GL-ZY001 与 ICE-PZY-001 解析为 ICE-P-ZY001；REPO-012 与现有健康接口继续正常。",
    "out_of_scope": [
      "不修改人类登录入口或 SSH",
      "不修改广州前门与现有隧道",
      "不部署企业应用栈",
