- SQL 作为语言接入现有提交流程，judge_task 按 language 分流到 SQLJudgeDispatcher - judge/sql_runner.py：内存 SQLite 判题核心，查询题比结果集/增删改题比表状态， authorizer + progress_handler + max_page_count 三重防护 - dispatcher 提取 _process_judge_result/_push_status 供 SQL 判题复用（行为不变） - 测试点通道支持 1.sql..N.sql 压缩包，出题只需数据脚本+标准答案 - Problem 增加 sql_config 字段；options 数据迁移注册 SQL 语言 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

"""SQL 题判题调度：不走 JudgeServer 沙箱，在 dramatiq worker 内用 sqlite3 直接判题。

复用 JudgeDispatcher 的 _process_judge_result 完成状态聚合、统计、排名和 WebSocket 推送，

因此比赛排名、rejudge、题目统计的语义与沙箱判题完全一致。
