+# WP13 Compose 离线交付、备份与恢复
+
+本目录提供首期示范环境的可执行交付链。它以
+`deploy/docker/docker-compose.yml` 为唯一 Compose 定义，不建立第二套人工维护的
+服务清单。
+
+## 1. 联网构建机生成离线包
+
+先同步发布副本并构建默认服务镜像：
+
+```bash
+bash deployment/sync_release.sh
+docker compose -f deploy/docker/docker-compose.yml build backend runner frontend
+bash deployment/compose/package_offline.sh --version <发布版本>
+```
+
+产物位于 `dist/dataops-platform-offline-<发布版本>.tar.gz`，包含默认 profile
+所需镜像、Compose 配置、数据库迁移、安装脚本、版本清单和全文件 SHA-256。
+可选的 MCP、LightRAG shadow profile 不属于示范版默认启动范围，应另行生成并验收
+扩展镜像包。
+
+## 2. 离线主机安装或升级
+
+```bash
+tar -xzf dataops-platform-offline-<发布版本>.tar.gz
+cd dataops-platform-offline-<发布版本>
+cp deploy/docker/.env.example deploy/docker/.env.local
+# 通过企业批准的密钥渠道填写 .env.local，不在终端或工单中粘贴密钥。
+bash operations/install_offline.sh \
+  --bundle-root "$PWD" \
+  --env-file "$PWD/deploy/docker/.env.local" \
+  --project-name dataops-test
+```
+
+安装顺序固定为：校验全部文件、载入镜像、解析 Compose、检查镜像、启动
+`--no-build`、等待健康、核对 Alembic current/head。升级不调用数据库 downgrade。
+
+## 3. 一致性备份
+
+备份会先导出 PostgreSQL 逻辑备份，再在明确的维护窗口内停止 Compose 项目，
+对所有带该项目标签的卷做一致性快照，最后自动重启原项目：
+
+```bash
+bash deployment/compose/backup.sh \
+  --compose-file deploy/docker/docker-compose.yml \
+  --project-name dataops-test \
+  --output-dir /safe/dataops-backups/<备份编号> \
+  --confirm-maintenance-window
+```
+
+输出包括 `postgres-all.sql`、`alembic-current.txt`、所有卷归档、
+`backup-manifest.txt` 和 `checksums.sha256`。备份目录不得放入 Git。生产环境还需
+复制到独立故障域、加密并按企业保留策略管理。
+
+## 4. 恢复演练
+
+默认禁止原项目原位恢复。演练必须使用新的项目名、独立端口和精确确认：
+
+```bash
+cp deployment/compose/.env.rehearsal.example /tmp/wp13-rehearsal.env
+bash deployment/compose/restore.sh \
+  --backup-dir /safe/dataops-backups/<备份编号> \
+  --compose-file deploy/docker/docker-compose.yml \
+  --env-file /tmp/wp13-rehearsal.env \
+  --project-name dataops-wp13-restore \
+  --confirm-project dataops-wp13-restore \
+  --start
+```
+
+恢复先验签，再确认目标不存在，随后创建目标项目专属卷并解包。任何确认不一致、
+校验失败、目标已存在或与源项目同名的情况都会在写入前失败关闭。
+
+## 5. 版本回滚
+
+回滚需要同时指定“上一版离线包”和“升级前备份”，并恢复到新的候选项目。验证完成
+后由变更负责人执行流量切换：
+
+```bash
+bash <上一版目录>/operations/rollback.sh \
+  --release-root <上一版目录> \
+  --backup-dir <升级前备份> \
+  --env-file /tmp/wp13-rehearsal.env \
+  --project-name dataops-rollback-candidate \
+  --confirm-project dataops-rollback-candidate \
+  --start
+```
+
+本流程不会执行 Alembic downgrade。正式生产切换、旧项目下线和备份删除均需要企业
+变更审批，不由脚本自动执行。
