 - 2026-07-14 BRD 4.3.4 场景覆盖补齐：原生活顾问 12 条 seed 只有投诉、催费、报修、突发求助，缺少 BRD 明确要求的服务推介/增值与日常服务；现新增 `service-promotion-needs`、`daily-service-followup` 两条补充场景及五维 Rubric，保留原 12 条核心场景不变。提供幂等迁移 `aihr_20260714_practice_brd_scenarios_mysql8.sql` 和临时库回归脚本；该内容属于待业务复核的初始化素材，不等同于正式试点样本。
 - 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。
