已按“实验成绩独立管理”完成修改。
每个实验项目独立建成绩单，支持评分项、参与状态、补做次数、安全违规、报告地址和教师评语。 流程为：录入 → 学院审核 → 教务发布；学生只能查看已发布成绩。 自主预约实验支持同步有效预约名单，已评分记录不会被误删。 课程成绩可将已发布实验成绩汇总为快照导入指定分项；导入后锁定，不能手工篡改。 实验项目成绩不完整时，对应课程分项保持空白，不按 0 分处理。 一级“实验管理”菜单下增加“项目与场次”“实验成绩”；学生端增加“实验安排”“实验成绩”。 已生成 MySQL 正式迁移及 SQLite 开发迁移，尚未操作生产数据库。 界面采用“实验项目 → 独立评分 → 审核发布”工作台设计。
