 # BRD 功能审查与未完成项记录
 
+- 2026-07-15 BRD G3/4.7 生产迁移缺口修复：`aihr_knowledge_gap` 与 `aihr_knowledge_answer_feedback` 此前只在 `AihrSopSeedService` 运行时懒建，生产迁移 Runbook 没有对应版本化脚本，可能出现应用启动前结构缺失、反馈/知识缺口审计不可用。现新增幂等 MySQL 8 迁移，兼容旧反馈表补齐 `review_id/reviewer/reviewed_time`，纳入迁移 Runbook、迁移回归测试和 `demo-check` marker；仅补结构，不写业务数据，尚未执行生产迁移。
+
 - 2026-07-15 BRD 剩余功能复核：重新核对动态难度、案例视频和 SOP 反馈治理三条链路。场景表已有 `difficulty` 但没有 HR 确认的升降级阈值、候选场景映射和人工关闭规则；案例当前能保存/回放脱敏音频，但没有正式预渲染视频样片及对应学习场景契约；SOP 负反馈队列已有问题、片段、评审状态和人工复核入口，但没有经业务批准的纠正内容、版本替换和署名入库规则。本轮不硬编码业务规则、不用音频冒充视频、不把“标记已复核”伪装成知识修复；以上继续作为 P1/发布前输入项跟踪。
 
 - 2026-07-15 BRD 4.7 知识答案负反馈闭环修复：SOP 检索此前在某问题命中的片段全部被点踩时仍保留原答案，违背“同一问题后续不再推送该条目”的约定；现由共享检索过滤返回无明确依据的答案并保留提示，不再把被点踩片段作为答案证据。新增 `AihrSopSeedServiceTest.allDownVotedHitsAreSuppressed` 和 `demo-check` marker；未修改业务数据，后续仍需正式员工问答样本验证替代答案质量。
