+## USER_TYPE=ant TUI 修复 (2026-04-02)
+
+`global.d.ts` 声明的全局函数在反编译版本运行时未定义，导致 `USER_TYPE=ant` 时 TUI 崩溃。
+
+修复方式：显式 import / 本地 stub / 全局 stub / 新建 stub 文件。涉及文件：
+`cli.tsx`, `model.ts`, `context.ts`, `effort.ts`, `thinking.ts`, `undercover.ts`, `Spinner.tsx`, `AntModelSwitchCallout.tsx`(新建), `UndercoverAutoCallout.tsx`(新建)
+
+注意：
+- `USER_TYPE=ant` 启用 alt-screen 全屏模式，中心区域满屏是预期行为
+- `global.d.ts` 中剩余未 stub 的全局函数（`getAntModels` 等）遇到 `X is not defined` 时按同样模式处理
