* 成绩查询控制器 - ScoreController
|

*
|

|
|
* 负责选手查询个人成绩，包括答题得分、作品评分和总分。
|

|
|
* 成绩发布后才能查看。
|

|
|
*
|
|||
|
|
* 主要接口：
|
|||
|
|
* - GET /api/score : 获取当前选手的（队伍）成绩详情
|
|||
|
|
*
|
|||
|
|
* 设计目标：一人考试，全组（同队伍）都能查看该队伍成绩。
|
|||
|
|
* - 考试以「队伍」为单位，仅一名成员（考试操作员）实际进入并作答；
|
|||
|
|
* 成绩（客观题/作品/演示阅卷分）落在操作员对应的记录上。
|
|||
|
|
* - 同队其他成员查看时，须解析到本队「考试操作员」的成绩并一致返回，
|
|||
|
|
* 而非各自读取自己（未考试、得分恒为 0）的行。
|
|||
|
|
* - 队伍身份以 aggregation.team_uid 为准（与考试锁 _enterExamWithTeamLock 一致），
|
|||
|
|
* 回退到 contestants.team_id（与 teams.id 关联）。
