 - 2026-07-14 BRD 4.3.4 场景 schema 发布补齐：只读核验发现生产缺少 `aihr_practice_scenario`、`aihr_practice_rubric`、`aihr_practice_rubric_dimension` 三张表；现新增只建结构的 `aihr_20260714_practice_catalog_schema_mysql8.sql`，并让补充场景迁移显式依赖该基础迁移。未写入生产数据，正式发布仍需按顺序执行基础 schema、场景 seed 与 SOP seed 迁移。
 - 2026-07-14 BRD 4.7 住宅 SOP 内容补齐：原知识库只有 3 份已解析住宅 SOP；现新增增值服务需求识别、日常服务回访两份 SOP 及各 3 个检索片段，reset SQL 与版本化迁移同步，临时库连续执行两次保持幂等。严格门禁已从 `sop_docs=3/5` 推进到 `5/5`；案例库、正式组织身份和正式试点证据仍未完成。
 - 2026-07-15 BRD G3 候选人面试操作角色边界修复：`/api/recruit/interview/start`、`answer`、`finish` 此前只要求登录，普通后台系统用户可绕过 HR/管理员权限创建或完成面试；现统一限制为 APP 候选人本人或 `superadmin/hr_operator`，候选人会话仍按本人手机号绑定。新增源码契约测试和 `demo-check` marker；尚未发布生产。
+- 2026-07-15 BRD G3 面试未知会话状态边界修复：系统用户调用 `answer` 携带不存在或已失效的 `sessionId` 此前会返回“已暂存”而不暴露会话无效；现统一要求会话存在且属于当前租户，`finish` 保留 HR 管理端既有的兼容性创建逻辑。新增服务回归测试和 `demo-check` marker；尚未发布生产。
