进度算法在学生路径和后台路径各写了一遍，于是各自漂了一段。后台那份 （resyncProgress）名叫「把所有参与者的进度重算一遍」，实际只更新分母和百分比： - 不碰 total_score。改题目分值时专门调了它，函数体里却没这个字段，score 类奖章 因此按陈旧分数判定。 - 不碰 is_completed。加一道题之后分母变大、百分比掉下来，人还标着「已完成」。 - 不清理 progress_detail。删掉一道题之后 least(completed, total) 只保证不超过分母， 会把没做的题算成做了 —— 3 题的题单只做出 C，删掉 C 就变成 1/2 = 50%。 - 不重算奖章。题目集一变 all_problems 的达标面就变了，没有任何地方补发。 最后一条攒下了实打实的欠账：8-07 的快照里 53 条应发未发，涉及 30 名学生，误发 0 条。 其中 23 条来自 2026-05-22 00:50 那次一分钟内跨 7 个题单的批量补进度 —— 进度补了， 奖章没人回头判。 两边不再分叉的唯一办法是只留一处算法，所以抽出 services/problemset.ts： computeProgress 是纯函数，学生做出一题和后台改题目都只是调用者； eligibleForBadge / recalculateBadge / resyncProgress 一并搬过来，补发脚本才能复用 同一套判定。批量写回仍是一条 UPDATE ... FROM (VALUES ...)，没退回逐行往返。 顺带修掉空题单的坑：isCompleted 加了 total > 0 前提。原来 0 === 0 也成立，老师先建 题单、学生先加入、题目后加，加入那一刻就写下 complete_time 并计进「完成题单数」成就， 而且后面补上题目也不会自愈。 一处行为变化：退回未完成时 complete_time 会清空。后台那份原来保留旧时间，学生那份 一直是清空的，统一成后者 —— 否则同一行会出现「未完成 + 有完成时间」，破坏现有数据里 「complete_time 非空 ⟺ is_completed」这条不变量。代价是加题再删题会把历史完成时间 洗成「现在」。 scripts/backfill-problemset-badges.ts 补历史欠账，默认只读预演，--apply 才落库。 只要存在误发就拒绝执行并打出名单，要连收回一起做得显式加 --allow-revoke —— recalculateBadge 的删除是真删，user_badge 的 earned_time 没有别处备份。 在生产快照上实跑：补发 1180 → 1233 条，复核全部一致，历史 earned_time 未被刷新； resyncProgress 对题单 9（7 题 / 117 人 / 100 人完成）加题后正确退回 0 人完成并收回 100 枚奖章，删题后完整恢复；改题目分值 10→20 使总分和 7460 → 8590，正好 +113×10。 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01QqqZwxtXLo2GTqMi51C94D
