 - 2026-07-14 BRD G3/G6 生产验证码安全边界修复：`CaptchaController` 原先允许通过 `aihr.sms.demo-fixed-code-enabled=true` 在 `prod` profile 放行固定短信验证码，和项目要求的“生产代码级禁用”冲突；现仅允许非 `prod` profile 使用 `aihr.sms.dev-fixed-code`，删除生产覆盖开关，并新增源码契约回归与 `demo-check` marker。未修改线上配置或生产数据。
 - 2026-07-14 本地验证环境一致性修复：项目 Docker 编排使用 MySQL `13306`、Redis `16379`，但 `application-dev.yml` 原先仍默认连接 `3306/6379`，导致 admin Spring 全量测试误连其他本机容器；现 dev 数据源改为 `AIHR_MYSQL_*`、`AIHR_REDIS_*` 可覆盖配置，默认与本项目编排一致，生产配置不变。`ruoyi-admin` 全量测试已通过。
+- 2026-07-14 BRD 5.4/G3 线上岗位身份映射修复：生产关闭组织姓名/部门展示时，`orgSnapshotWhere` 原先也排除了 `person_phone`，认证 APP 用户的手机号查询可能返回空结果并错误降级为员工/手动选岗；现隐藏展示字段模式仍允许按手机号过滤，但不返回手机号或姓名部门。新增回归测试与 `demo-check` marker；线上需重新发布后再用正式组织映射数据验证。
