 - 2026-07-14 BRD 生产迁移回归固化：新增 `scripts/tests/aihr-schema-migrations.test.sh`，在临时 MySQL 库验证 SOP 主体/版本字段和组织入职日期迁移面对旧表、缺前置表时可安全执行且重复执行幂等；不写入开发库业务数据。
 - 2026-07-14 BRD 生产迁移回归扩展：同一临时 MySQL 回归测试同时连续执行 `aihr_20260714_practice_evidence_mysql8.sql`，确认 `aihr_practice_audio` 与 `aihr_practice_calibration` 两张证据表可重复创建；不写入开发库业务数据。
 - 2026-07-14 BRD 当前开发库审查快照：生活顾问启用场景 `12`、校准记录 `20`、已评审 SOP `2`，但住宅 SOP 文档仅 `3/5`、已入库案例 `2/20`，在职组织快照 `3001` 条中手机号可映射仅 `1` 条；这些数据不能作为正式试点通过，下一步优先补内容负责人确认的核心流程素材和正式组织身份映射，不用烟测记录替代。
+- 2026-07-14 BRD 严格门禁绕过修复：`AIHR_DEMO_CHECK_LIBRARY_ONLY=true` 仅允许测试加载脚本函数，和 `AIHR_PILOT_STRICT=true` 同时使用时现在直接失败，避免调试开关把正式试点检查静默跳过；新增回归断言，未修改业务数据。
