 # BRD 功能审查与未完成项记录
 
+- 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。
+
 - 2026-07-15 严格试点门禁可读性补强：`scripts/demo-check.sh` 新增 `catalog_schema=3/3`，严格模式在场景/Rubric 三张基础表缺失时明确失败，而不是只输出空的场景统计；临时库回归覆盖缺少 Rubric 表的 `catalog_schema=1/3` 状态。该修复不改变生产数据和业务门槛，仅让生产迁移缺口可被明确识别。
 
 - 2026-07-15 严格试点门禁补强：`scripts/demo-check.sh` 原先只检查 SOP 评审的 `prompt_version` 字段，未检查 6 个内置 Prompt 是否实际落库；现新增 `prompt_templates=6/6` 查询和 strict 失败条件，并在 `scripts/tests/demo-check-pilot-gates.test.sh` 的临时库加入 6 个模板回归。该修复能阻止“schema 已迁移但 Prompt 内容为 0”的生产状态被误判为可验收；未修改生产数据。
