 - 2026-07-14 BRD G3 组织快照质量门禁修复：生产默认关闭 `store-display-fields` 时，`AihrOrgSyncService` 原先在 `orgRow()` 内先清空姓名/部门，再以已屏蔽的 `OrgRow` 计算 `suspectText`，外部姓名/部门中的问号乱码可能被漏报，覆盖写入保护因此不完整。现先基于外部原始字段计算 `suspectText`，再独立保存质量标记；展示字段仍按生产脱敏策略清空，组织表结构和写入字段不变。新增 `AihrOrgSyncServiceTest` 回归和 `demo-check` marker；未修改生产数据。正式同步仍需真实上游快照、手机号映射和法务确认。
 - 2026-07-14 BRD 4.3.4 每日三题资格边界修复：`aihr_org_snapshot` 没有 `hire_date` 时，旧逻辑用“移动端训练记录少于 3 次”推断新员工，可能把老员工或临时账号误派每日三题。现仅在本地 `application-dev.yml` 显式开启 `allow-legacy-daily-drill-fallback=true`；生产默认关闭，正式环境必须等组织同步提供 `hire_date` 后再按三个月窗口派发。新增边界测试和 `demo-check` marker；不改数据库结构，不伪造正式新员工数据。
 - 2026-07-14 BRD 4.3.4 每日三题生产 profile 硬门禁：旧回退即使被环境变量显式打开，仍可能在生产 profile 生效；现仅允许 `dev/local` profile 使用训练次数兼容回退，`prod` 或混合 profile 强制关闭。新增 profile 边界测试和 `demo-check` marker；未修改数据库结构或生产数据。
+- 2026-07-14 BRD 6.3 SOP 来源标识修复：SOP 检索成功时前端原先忽略 API 返回的 `records`，后端返回的内置记录也没有来源字段，可能把演示文档显示成真实知识库；现 API 成功态只使用响应记录，内置记录明确标记 `source=demo`，失败/未检索态继续保留已有回退提示。未修改知识库数据或生产环境。
