 - 2026-07-14 BRD G3 移动首页权限复核：发现公开首页方法对已登录 SYS 用户仍可能调用全局统计分支；现要求只有 APP 用户且身份非空才读取员工/主管动态数据，后台系统用户和异常身份统一返回无业务统计的公开 seed。AIHR 全量测试 `70/70` 通过，未修改生产环境。
 - 2026-07-14 BRD G3 音频读取权限复核：发现移动端音频下载接口对已登录 SYS 用户未校验角色，普通后台账号理论上可枚举 `ossId` 读取训练录音；现复用 `superadmin/hr_operator` 门禁，APP 用户继续按本人/主管项目范围校验，其他身份返回 403。AIHR 全量测试 `70/70` 通过，未修改生产环境。
 - 2026-07-14 BRD 4.4 每日三题资格补强：每日派题现在在组织快照存在 `hire_date` 列时按“入职日期至今不超过 3 个月”判断，边界按自然月且包含当天；旧 Demo 快照没有该列时继续使用“移动端训练记录少于 3 次”的兼容回退。正式试点仍需在外部组织同步落地并校验 `hire_date`，不能把回退口径当成正式新员工资格。
+- 2026-07-14 BRD G3 候选资料审核状态复核：候选人资料审核接口此前在空请求体时默认写回“待审核”，可能覆盖已有“已通过/已驳回”状态；现要求审核动作显式提交三态之一，空值和未知状态直接拒绝，避免后台误操作回退审核结论。
