 - **Native TLS listeners require a Node Host**: the worker's `node:https.createServer` rejects activation rather than substituting plaintext. The preview's internal HTTP tunnel does not bind sockets; browser-facing HTTPS belongs to its deployment server.
 - **Desktop product telemetry is unavailable**: `got.post` reports an explicit worker-host refusal. Got and its Node HTTP dependencies are excluded from the browser image; Desktop reporting remains disabled in the preview composition.
 - **Host package commands are unavailable**: `execa` reports an explicit worker-host refusal; the preview cannot run pnpm, install plugins, or install native dependencies.
+- **pi-ai model requests are unavailable**: the replacement exposes a fixed subset of installed provider identifiers with no models, allowing the adapter to register configuration metadata. Its identifiers must stay valid when pi-ai is upgraded; inference entry points report an explicit worker-host refusal.
 - **PTC Node programs are unavailable**: the process shim exposes `/dsh/bin/node` as its executable identity so the provider can activate, but the Worker has neither a Node executable nor `stripTypeScriptTypes`. Program execution fails before launching a child.
 - **Office conversion requires a Node Host**: the LibreOffice kit replacement rejects converter creation with `unavailable`. The browser image excludes the kit and its engine dependencies; the Office preview reports that conversion is unavailable.
 - **Filesystem watchers observe only the mounted VFS**: image seeding is silent and the VFS has no symlinks or external writers. `persistent`, `ref()`, and `unref()` preserve the Node API but cannot control a dedicated Worker's lifetime because browsers expose no ref-counted event loop.

 - **原生 TLS 监听器需要 Node Host**：worker 的 `node:https.createServer` 会拒绝激活，不会替换成明文。预览内部的 HTTP 隧道不绑定套接字；面向浏览器的 HTTPS 由部署服务器提供。
 - **桌面产品埋点不可用**：`got.post` 明确报告 worker host 不支持该调用。浏览器镜像不包含 Got 及其 Node HTTP 依赖；预览组合不启用桌面上报。
 - **宿主包管理命令不可用**：`execa` 明确报告 worker host 不支持该调用；预览无法运行 pnpm、安装插件或安装原生依赖。
+- **pi-ai 模型请求不可用**：替代实现暴露已安装提供方标识的固定子集，不包含模型，使适配器能够注册配置元数据。升级 pi-ai 时必须保持这些标识有效；推理入口明确报告 worker host 不支持该调用。
 - **PTC Node 程序不可用**：process shim 用 `/dsh/bin/node` 表示可执行文件身份，使 provider 能够激活，但 Worker 既没有 Node 可执行文件，也没有 `stripTypeScriptTypes`。程序执行会在启动子进程前失败。
 - **Office 转换需要 Node Host**：LibreOffice kit 的替代模块以 `unavailable` 拒绝创建转换器。浏览器镜像排除 kit 及其引擎依赖；Office 预览提示转换不可用。
 - **文件 watcher 只能观察已挂载的 VFS**：镜像 seed 不产生事件，VFS 也没有符号链接或外部写入方。`persistent`、`ref()` 和 `unref()` 保留 Node API，但浏览器没有引用计数事件循环，因此这些接口不能控制 dedicated Worker 的生存期。
