// @vitest-environment jsdom
// privateLibraryPane.test.js —— 我的资料面板（T1 骨架，对齐 A1 交付）
// 对应用例：TC-PRIV-L3-04 ~ TC-PRIV-L3-07（docs/team/TEST_CASES_PRIVATE.md）
// UI_SPEC §9.2：标题「📁 我的资料」+ 计数；列表项 name/size/time；删除 confirm → removeLibrary → 刷新；
// 空态「尚无上传资料。在对话框拖拽 PDF / DOCX / TXT 上传。」；加载失败显示重试按钮。
// 修正（A1 交付对齐）：
//  - 可变状态用 vi.hoisted（vi.mock 工厂被提升，引用顶层 let 会 TDZ）；
//  - A1 onDelete 内部 await setTimeout(0)（宏任务）后才刷新——用例必须等待宏任务
//    （vitest 默认未启用 fake timers，setTimeout 真实执行，flushPromises 不排干它；
//     用小轮询或 vi.useFakeTimers+advanceTimersByTimeAsync；本文件用真实定时器轮询辅助函数）。
