租户首页为一个关着的命令面板读整个对象注册表（HotCRM 约 875 KB 原始 / 129 KB gz）：HomeLayout 挂载时就把 useMetadata().objects 交给面板（cloud#2914 子卡 OU-1） #29121
Description
coordinator#1 · hotlong · session_6eb9ec2e0e3f410b91239dab7a337b9e
立卡门类别：①（父单 cloud#2914 是 ④；round 10 已测、未立的杠杆 OU-1）
Reader: domain:ui 车道。ui/packages/app-shell/src/console/home/HomeLayout.tsx:76（const { apps, objects } = useMetadata()）与 :122（objects={objects ?? []} 交给命令面板）；改为面板打开时再读，或用当前应用的 bundle / 对象范围。不需要新组件或 spec 契约变化。建议档 p3，由分诊定。
Dedupe: repo:objectstack-ai/objectstack is:issue HomeLayout objects palette total=0；home object registry command palette closed total=36（#28981 #27377 #28965 #27438，均为 QA 汇总或无关），无同题。
业务理由：每个进入租户首页的用户。首页上没有任何地方需要全部对象定义，面板默认是关的；整表是首页最大的元数据载荷，网络慢时首页因此多等几秒，服务端也要为每次首页打开序列化一遍整个注册表。
来源
2026-11-02 staging 页面性能评估（cloud main cd4e2e1f，objectstack pin 6cbdef1e；控制面 cloud.objectos.app，租户 os-2ph4c1.objectos.app / HotCRM 6.0.0；内置浏览器面板 zh-CN，读 resource timing 与 v2.7.0 起的 Server-Timing: runtime/placement/origin，辅以 Workers Observability）。维护者在会话里说「评估一下核心页面新版的性能有改进吗，还能继续优化吗」「相关性能优化使用 fable 评估后立卡」；本卡经第二个审核会话按 origin/main 核对落点与查重。
已实测
- round 10（cloud#2914 评论 6396581531）：租户首页打开读 875 KB 的对象注册表，只为关着的命令面板。
- main 上代码原样：
HomeLayout.tsx:76在挂载时取objects，:122传给面板。本轮没有单独复测首页，判据沿用 round 10 的测量。
验收
- 租户首页整页打开的 resource timing 里没有不带
?package=/ 名字范围的GET /api/v1/meta/object。 - 打开命令面板后对象搜索结果与现在一致。
- 请求计数测试 + 消融。
