- domain/rules: 计分与排名解耦、破纪录按组别、tieBreak 生效、调整分不丢、移除 aggregate 假能力 - realtime: 新建 internal/dto，快照三项契约对齐，/ws 只认会话身份 - httpapi: 流水幂等、standings 整表载荷、广播接线、强制改密、XFF 防伪造、records 写入、审计、赛事包内容、发布前备份、result.points、实例列表 - web: FormData 上传、YAML 解析、快照归一化、大屏解析层、bootstrap 降级、访客判定、主题切换 - console: 优雅关闭握手、中文化、免验证改管理员账号、选屏与日志轮转修复 - docs: 用户文档三份 + README - 主代理: 破纪录加分接线（levels 未加载导致恒 0）
