 ## 发布前置条件
 
 1. 确认发布窗口、DB 备份和回滚负责人；迁移脚本包含 `ALTER TABLE`，不能在无备份状态执行。
-2. 先执行 `scripts/release-preflight.sh` 的只读检查；生产静态资源、后端包和当前提交必须一致。
+2. 先执行 `scripts/release-preflight.sh` 的只读检查；生产静态资源、后端包和当前提交必须一致。若要同时核对线上结构，追加 `RELEASE_VERIFY_REMOTE_SCHEMA=true`，该开关只读检查必需表，不执行迁移。
 3. 确认迁移目标库、租户和字符集为 MySQL 8 / `utf8mb4`；脚本只允许在目标业务库执行。
 4. 生产组织同步凭据、AI 供应商留存/费用口径和正式试点窗口仍未闭合时，不要把迁移完成宣称为 BRD 验收完成。
