 - `src/contracts/assetKind.ts`：消费 Rust 生成的 `GameCreationAppAssetKind`，未知输入记录 `rawKind` / `sourceContext` 并返回 `unknown`，不做旧 alias 转换。
 - `src/features/project-workspace/resourceReferences.ts`：资源引用 kind 改为生成枚举类型并通过 parser 收口。
 - `src/view/project-development/index.tsx`：画布引用入口通过同一 parser 构造资源引用 kind。
+- `src/features/ui-editor/uiDesignResourceBridge.ts`：UI 原型 manifest kind 只接受 `ui-design`，UI 文档链接只接受 `ui-design-doc`；旧 `ui-prototype` 不再 alias。
 
 其余 `packages/shared` import 和前端 manifest `kind: string` 字段仍未迁移，继续作为后续小切片，不在本次提交中伪装完成。
