fix(题单): 进度记账挪到判题这一路，不再靠前端回调

前端记账是这条链上最松的一环：SubmitCode.vue 看到 AC 就回调 PUT /problem-set-progress，而且只认路由参数里那一个题单。于是 · 从普通题库入口做出同一道题 → 不计进度 · 网络一抖、页面提前关掉 → 进度静默丢失 · 一道题同时在两个已加入的题单里 → 只有进去的那个记上旧栈为此专门有个管理命令 fix_problemset_progress 定期按实际提交补账 —— 2026-05-22 00:50 那次一分钟内跨 7 个题单的批量补进度就是它跑的。改成判题落库之后由 judge/run.ts 记账（recordSolvedProblem），记进该用户**所有**已加入且包含这道题的题单。位置在最后那条 publishSubmissionUpdate("finished") 之前，所以前端收到「判完了」时进度已经落库，跳回题单页看到的就是新数据。前端那次回调删掉。不按 visible / status 过滤：进度是学生自己的记录，老师把题单藏起来不该让它停止累积；更要紧的是这条口径必须和补账工具一致，否则补账工具会永远「发现」差异。实跑（本地起 api + worker 真判一次）：提交时**完全没带 problemSetId**，判完之后 progress 变成 1/1 100% 已完成、10 分、complete_time 落下、all_problems 奖章发出、 problemset_submission 也记上了。 ## 补账那半 backfill-problemsets 前面加一道「按实际 AC 补进度」，移植自旧栈的 fix_problemset_progress，口径和 recordSolvedProblem 逐条对齐（非比赛提交、 ACCEPTED 或 AST_CHECK_FAILED、取最早那次）。补录的格子先并进 detail 再重算，所以预演里的奖章名单是照着「补完账又重算过」的进度算的，和 --apply 的结果一致。在生产快照上实跑：合计：补录 10 道题，进度 497 条要重算（完成 +23 / -0），奖章补发 56 条、收回 0 条已订正 11 个题单 → 复核通过 user_badge 1180 → 1236，已完成 621 → 644，problemset_submission 7735 → 7745 「未完成但有完成时间」仍是 4 条；重复跑幂等补录的 10 道分布在题单 4/5/6/15/16（1/1/1/4/3），和离线独立算的数字逐个对上 —— 其中题单 15 那位 AC 了全部 12 题却一直显示未完成。 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01QqqZwxtXLo2GTqMi51C94D

- * 两笔历史欠账：
+ * 1. **进度漏记**。判题这一路记账（services/problemset.ts 的 recordSolvedProblem）是后来才有的，
+ *    在那之前靠前端 AC 之后回调，只认路由参数里那一个题单：从普通题库入口做出同一道题不计进度，
+ *    网络一抖就静默丢失。这里按实际 AC 记录补回来 —— 移植自旧栈的管理命令
+ *    `problemset/management/commands/fix_problemset_progress.py`。
+ * 2. **奖章漏发**。奖章原本只在学生做出一道题那一刻发，进度从别的路径变了就没人回头判过达标。
+ *    生产快照里 53 条应发未发、涉及 30 名学生 —— 其中 23 条正是上面那个管理命令留下的：
+ *    它补进度，而旧栈的信号只挂在 ProblemSetProblem 和 ProblemSetBadge 上、不挂 Progress。
+ * 3. **算法改过**。分母只算必做题（选做不再卡完成）、空题单不再算完成、total_score 跟着分值走。
+ *    已有的行要跑一遍才会按新规则重算。
 *
- * 1. 奖章原本只在「学生做出一道题」那一刻发（`PUT /problem-set-progress`），进度从别的路径
- *    变了 —— 后台加减题目、旧栈的 fix_problemset_progress 批量补进度 —— 就没人回头判过达标。
- *    生产快照里 53 条应发未发、涉及 30 名学生。
- * 2. 进度的算法后来改了：分母只算必做题（选做题不再卡完成），空题单不再算完成，
- *    total_score 跟着题目分值走。已有的行要跑一遍才会按新规则重算。
- *
- * 两件事一起做，因为它们是同一笔账：进度一变，奖章达标面就跟着变，
- * 所以落库走的是 resyncProgress —— 它重算进度之后会顺手重算这份题单的全部奖章。
+ * 三件事必须一趟做完，因为它们首尾相接：补进度 → 完成状态变 → 奖章达标面变。
+ * 落库走 resyncProgress，它重算进度之后会顺手重算该题单的全部奖章。
 *
 * 默认只读，把差异打出来；确认无误再加 --apply 落库。
 * 只要预演里出现「收回」就先停下来让人看清楚，要真的收回得显式加 --allow-revoke ——
