- 流程图画到 A / S 拿到的题单徽章、成就原来不弹：流程图那条 WebSocket 只认评分完成 / 失败， 成就消息被丢掉了，要等下次换路由拉 pending 才出来 - 强制点评弹窗读不出点评、或者一直交不上时，「下一题 / 继续」按钮也给出来：原来弹窗关不掉， 只能按浏览器后退；拦下换题时就记上「继续」，按钮文字不会写错 - 「放回编辑器」走正常的换语言路子（画流程图时切回代码编辑器、读那门语言的草稿）； 这道题已经不收的语言（0020 摘掉的 Java / JS / Go）置灰，只能复制 - 举着手时刚交对、1.5 秒内点下一题：原来「确定要换题吗」要问两遍（点评完再问一次）， 现在同意过的那个地址不再问 - 课堂看板上评分中、评失败的流程图不再算「尝试过」，和学生的课堂条一个口径； 新加的流程图查询和其他查询并行，不再多等一轮数据库 - 课堂条的数据只认最后发出的那次请求：进页面那次后到的话会把刚做完的那道盖回「没做」 - 「A / S 算做完」收进契约，前后端只留一份；协作中老师的判断统一用 useTeacherCollab； 几处放错位置、说法过时的注释 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* 题目点评轮盘：七个选项，每人每题只能评一次，做对了才能评。
|
||
*
|
||
* 和原来那个轮盘比：
|
||
* - 每块上**直接写着表情和名字**，字号跟着轮盘走（最大 16px），不用先把鼠标移过去才看得清；
|
||
* 原来每块的字只有 12px 左右
|
||
* - **选之前哪里都没有人数**（后端本来就要自己评过才返回 counts），圆心只报悬停的那一项，
|
||
* 免得跟风；选完就地变成玫瑰图：每块从里往外填一段，长短按人数，标出「N 人」
|
||
* - 扇区是 SVG 画的。原来是 CSS clip-path 加 `color-mix()`，后者 Chrome 111 才有，
|
||
* 机房 105 那档整条声明作废、扇区没有底色
|
||
*
|
||
* `guard`：AC 之后那个强制弹窗用。弹窗是自己冒出来的，学生手还在键盘上、鼠标还停在
|
||
* 原来的位置（很可能正好压在某一块上），所以前 600ms 点不了，也不响应 Enter / 空格；
|
||
* 扇区不进 Tab 顺序，不会被预选。抽屉里的是学生自己点开的，不设防、键盘能用。
