- database-backup-to-oss.mjs 新增 --minimal/--retain-snapshots：按上游 retention 语义只备份最近 N 份 snapshot、覆盖最老保留 snapshot 的 commitlog 边界段及其后全部段，外加身份/配置/控制库/模块字节，且不停止任何服务
- 备份检查脚本补充 minimal 计划用例（保留次新+最新 snapshot、丢弃更早 snapshot 与 clog 段、状态路径齐全、保留数校验）
- 发布前备份默认走 minimal 热备（GENARRATIVE_STDB_PUBLISH_BACKUP_MINIMAL=0 可回到冷备），不再需要 44.7GiB 冷备空间
- Server-Provision 新增 DATABASE_BACKUP_PROFILE=files-minimal 与 systemd drop-in，release 推荐使用并继续禁止 files-history
- 运维文档与共享记忆记录上游 retention 依据、实测 40G→3.6G 与不停服热备口径
