// P2-9（audit C-4）配套：createFileOps 不得构造时缓存 editor。
|
||
//
|
||
// 背景：app.js 顶层不再 new MarkdownEditor（CM6 走 dynamic import，bootstrap
|
||
// 里才实例化），所以 createFileOps 在模块 eval 时拿到的 controls.editor 是
|
||
// null。file-ops.js 若构造时 `const { editor } = controls` 解构缓存，之后
|
||
// bootstrap 给 editor 赋值也传不进来 —— deleteFile 等路径 syncDirtyFromEditor
|
||
// (state, null) 直接 TypeError。
|
||
//
|
||
// 契约：controls.editor 必须运行时现取（app.js 侧用对象字面量 getter 提供
|
||
// 活视图），createFileOps 之后赋值也生效。
|
||
|
||
// @vitest-environment jsdom
