Go-live 备份 Dry-run

展示备份能力探测、schema-only dump dry-run 和当前不执行归零的安全边界。

当前 Gate

GO_LIVE_ZERO_BASELINE_BACKUP_RESTORE_REHEARSAL_GATE

备份与 restore 演练准备。

当前动作

dry-run only

不写库、不归零。

红线

不覆盖当前环境不反写飞书

PostgreSQL

check

pg_dump 与 schema-only dry-run 已探测。

Webroot / Workspace

ready

已探测 webroot 与 workspace 备份能力。

配置与日志

read only

Nginx/systemd/logs 仅做读取能力探测，不修改配置。

当前动作

no write

没有执行归零，没有恢复覆盖当前环境。

下一步批准语句

确认执行 HRMS-GO-LIVE-ZERO-BASELINE-BACKUP-REHEARSAL-1：在隔离环境执行完整备份与 restore 演练；不覆盖当前环境、不执行归零、不反写飞书。
