服务端同步恢复回来的记录不保证结构完整(旧结构或半截写入)。缺少 videoId 的记录会让 HistoryItem.tsx:24 与 FavoritesItem.tsx:21 在渲染期拼播放地址 时对 undefined 调用 toString(),抛出未捕获异常。由于 getVideoUrl() 是在 渲染 href 时调用的,React 会直接卸载整棵树,首页白屏且刷新无效——该账号 只能靠直接改库才能恢复。 新增 lib/utils/sync-records.ts 做可渲染性判定(要求 videoId、source、 title 齐备),在云端拉取入口 useCloudSync 与 HistoryList / FavoritesList 各过滤一次:脏数据进不来,已经落库的也渲染不出来。
