submission 新增 problemset_id，学生从 /problemset/:id/problem/:pid 入口提交时 前端带上、后端落库，提交列表在题目后面挂一个「题单 xxx」的标签，点了进题单。 只是来源标记：题单进度和奖章仍由判完之后的 recordSolvedProblem 按「已加入且含 这道题的所有题单」记账，和从哪个入口进来无关，所以这个字段带错顶多标签不准， 不影响成绩。校验只确认这道题在那个题单里 —— 不查 visible / status、也不查有没有 加入，藏起来的题单里还困着已加入的学生；对不上就当没带，提交照收。 外键 ON DELETE SET NULL：删题单不该带走提交，清掉标记就行。索引建成部分索引 （WHERE problemset_id IS NOT NULL），绝大多数提交不来自题单，全列索引是给 12 万行 白建一遍；谓词能被 problemset_id = $1 蕴含，删题单时的外键检查也用得上它。 列表按页单独查一次题单标题，没有把 problemset join 进那条调过的深翻页查询。 比赛提交恒为 null：题单只收非比赛题。 历史回填从 problemset_submission 取「当年首次 AC 那条」，其余老提交无从判断入口， 一律留空。 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Y7AsqceaUfC81k7UCDcSk2

// 本文件由 `drizzle-kit pull` 从生产库自动生成，之后按下面几条手工维护。
|
||
//
|
||
// 2026-08-26：旧 Django 后端下线，7 张框架表（auth_group、auth_group_permissions、
|
||
// auth_permission、django_content_type、django_dramatiq_task、django_migrations、
|
||
// django_session）已由 0002_drop_django_leftovers 删除，drizzle.config.ts 的
|
||
// tablesFilter 随之移除。库里现在就是这 27 张业务表。
|
||
//
|
||
// 手工修正（都是 `pull` 自己没法无损 round-trip 的地方，改回去会让 generate 产生假 diff，
|
||
// 详见 CLAUDE.md「改 schema 走 drizzle migration」）：
|
||
// * bigint identity 的 maxValue 用字符串，不能写成 JS number 字面量（会丢精度）。
|
||
// * 索引不写 `.desc()`，生成 SQL 时方向会被丢掉。
|
||
//
|
||
// 关于 10 张表的 bigint id（problemset*、achievement、user_achievement、user_stat、
|
||
// user_badge、ai_analysis）：这是历史巧合不是设计——这些 app 的 0001_initial 生成时
|
||
// Django 还没设 DEFAULT_AUTO_FIELD，用了 3.2+ 的默认 BigAutoField；更早的表（user、
|
||
// problem、contest、submission）都是 int4。现存最大 id 一万出头，确实都用不上 bigint，
|
||
// 但 2026-08-26 评估后决定**不改**：省 4 字节/行毫无意义，ALTER TYPE 要重写整表并拿
|
||
// ACCESS EXCLUSIVE 锁，而且其中 6 处 id 被外键绑着得连坐。别再提这件事了。

* `lastWrongAnswer` 存的是**前端拼好的一句人话**（「选了 A、C」「第 2 空填了 xy」），

* 不是原始作答结构：七种题型的作答形状各不相同，存结构就得在后台按题型各写一套
|
||
* 渲染，而老师要看的只是「他错在哪」。前端本来就知道怎么把自己的作答说成人话。
