feat(成就): 多了 9 个好拿的档和「挑战成功」一条线，比赛里做的题也算，这学期八成学生多拿到成就
- 补档：做对 20 道、第一道中等题、交满 30 次、5 天交过题、一次就对 5 道、错 3 次后做对、一天做对 5 道； 新线「挑战成功」1 次 / 5 次 - 比赛里的提交也计入成就（比赛其实是单班测验，2612 班整班在比赛里做题，原来一个成就都没有）； 参加过几场比赛改成判题时就更新，以前只在后台重扫时刷新 - 奖杯收藏家从 15 个提到 20 个 - 0044 迁移：按新口径从提交记录重数指标，给达标的人补发（已经拿到的不收回） Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* 「做对几道 / 中等几道 / 困难几道 / 一次就对几道」按定义从提交表现数，不再逐次 +1。

* 参加过几场比赛、挑战成功几次也在这里一起数。
|

*
|
||||
* 原来是读一遍这道题之前的提交、判断「是不是第一次做对」再 +1，两处漏：同一个人同一道题
|
||||
* 两条提交挨着判完，两边都看见对方已经做对（都不加）或都还没做对（加两次）；重判一条
|
||||
* 做对的提交又会再加一次。2026-10 的库里 372 人的做对题数比实际多 1–4 道。
|
||||
* 现数是幂等的，怎么并发、怎么重判都是同一个答案。走 submission_public_metrics_idx，
|
||||
* 一个人的提交也就几百条。
|
||||
*
|
||||
* **比赛里的提交也算**（2026-11-03 起）：这里的比赛其实是单班测验，有的班整学期都在
|
||||
* 比赛里做题，不算的话一个成就都拿不到。比赛题是单独的题目行，不会和题库里同一道题重复数。
|
||||
* 个人主页 / 排名的做对题数（user_profile.accepted_number）仍然不含比赛，两边对不上是有意的。
