StudyHub 3.1.0

There is no separate 3.0.2: the fixes that were queued for it ship here together with 备考补习.

• 备考补习 (new, off by default). A page for revising before an exam. Its 考点清单 is a special material built from your slides or notes (and, if you have them, sample papers), with a two-level tree, and the older version kept when you rebuild it. Each point says 样卷考过（N/M 份）, meaning N of the M sample papers tested it, or 补充, meaning only the slides teach it; nothing is promised about the exam, and one sample paper gives the shape of the exam only, never frequencies. It is a host switch: turn on examBlueprint in the DSH plugin manager (设置 › 备考补习 says so, with a button to the plugin manager when DSH offers one). It has not been tried with real slides and a real model yet.
• Making a 考点清单 takes a click or two. 新建考点清单 opens a form that is already filled in. Your course materials are sorted into 课件, 样卷 and 大纲 with the reason written next to each (a name that only looks like a paper gets a hint, never the role), the course and the name are filled for you, and the rest (name, scope, language, reading note, other courses' materials) is folded under 更多设置. A wrong guess is one click on that row. No sample paper yet? 导入样卷 brings it in already marked. 设置 › 备考补习 keeps your own defaults: automatic guessing on or off, extra sample-paper words, the language of the list, and whether other courses' materials are listed.
• Building a 考点清单 is steadier and says what it keeps. A repeated question number (选择题 1 and 填空题 1) no longer drops or mixes up questions, and a long paper is no longer cut after 24 questions. Limits are checked before the first model call, with a plain refusal. A retry keeps the answers already read, and a slide window that cannot be read twice is skipped and noted in the list (marked incomplete) instead of voiding the whole build. Near-duplicate points from different slide windows are united (线性回归 and 一元线性回归) while C, C++ and C# stay apart. On such a task 接着做 and 停止 say what really happens, the finished card says 已保存考点清单 and opens the page, a list built from materials you have since changed says 资料已更新，建议重新生成, and a list no longer adds a course name of its own.
• 要求并行. A queued task can be started beside the queue by hand. The default is still one after another. A rate limit, an overload, a timeout or a model error sends a parallel task back to the queue, and nothing already finished is lost. Hover the queue state or the button for what it does. With several tasks running, 暂停 waits for the calls of all of them, not for a whole round.
• 创建题组 no longer shows three ways out for a selection that is too big. One block asks how to go on (分步出题, 按主题挑页面 or 一次出题) and shows only that mode, with one button. 按路径逐步出题 no longer fails every step with "tokenBudget 需要是不小于 1000 的整数": a step is a plain request with its own count, and the same reason for many steps is said once. Skipped steps (目录页 and the like) are folded.
• The 任务 console shows the goal and the points. A third tab, 目标与知识点, lists what the planning step chose, by batch, with each point's state and where it came from (a new record on question-generation jobs, no extra model call; a task from an older version has no list). The 日志 stamps the real finish time and says when a run is closing and closed; page counts say which pages are readable and which are in the original file; the 即时控制 row and the 跟随当前会话 choice fit at every width.
• A part that fails no longer sinks its round. A part whose set-up fails is recorded and the others go on; questions are credited to the section their quote belongs to even when the same sentence occurs more than once; a failed batch is no longer called 被停止.
• 错题本 opens by deck, folded, with filters (deck, search, 答错 / 未掌握) and loads up to 1000 mistakes instead of 100. 开始重练 still uses all of them.
• Home: 待发布草稿 sit in a folded section under the desk. The deck picker groups decks by course.
• 在右栏打开 says why when it cannot, instead of doing nothing; from the top-level StudyHub page it shows the conversation first and then opens the sidebar.
• Ask about a passage with follow-ups. Ask about a selection, ask about a term in the answer (up to 3 levels and 8 questions per thread), and keep notes per document revision, with 阅读 and 批注 modes.
• The reading header buttons are the same size.

Not fixed or not verified: 在右栏打开 and the 课堂实录 fix were only tried in a simulated DSH; 备考补习 was not tried with real slides, a sample paper and a real model (its form was only exercised in a browser preview that has no background task service); audio and PDF tasks do not record a start time; the usage estimate does not include 采纳审阅建议; a review issue with no owner still discards its whole part; opening a dropdown far down the settings page can jump the scroll position; the CI test that a library with an exam-point list stays readable in 3.0.0 is skipped there because the checkout has no tags; the final package passed the archive check (npm run release:check) but was not installed into a real DSH, so the first upgrade is the first real test of it.
