 ## 部署与持久化
 
-Gitea 工作流按应用路径触发：`waterfall-wiki.yml`、`studio.yml` 和 `python.yml`。waterfall-wiki 完成类型检查、单元测试、生产构建、冒烟和真实 PostgreSQL/S3 集成测试后部署；Studio 独立构建和部署。文档与作者数据本身不触发应用部署。
+Web 应用由 `waterfall-wiki.yml` 统一发布，两个应用的路径都能触发它：先检查并构建 Studio，再完成 Wiki 的类型检查、单元测试、生产构建、冒烟及隔离 PostgreSQL/S3 集成测试并部署 Wiki，随后部署 Studio，最后在指定服务器验收。顺序在同一个 ces-control 作业内保证，避免独立作业互相等待。PR 检查也运行隔离集成测试，但不部署。Python 检查仍由 `python.yml` 承担；文档与作者数据本身不触发应用部署。
 
 | 服务 | 入口/端口 |
 | --- | --- |
 | `waterfall-wiki` | 公网 `18131`，也是 Studio 的统一入口 |
 | PostgreSQL | `127.0.0.1:18132` |
 | 对象存储 | `127.0.0.1:18133` |
-| Studio | `127.0.0.1:18134`；公网通过 `/studio` 代理 |
+| Studio | `127.0.0.1:18134`；编辑器公网入口为 `/graphic`、`/infinite_canvas`，资源和 API 保留 `/studio` 代理 |
 | Python | 无网络端口，按需运行 |
 
 生产 Compose 项目仍为 `prompt`，部署根目录仍为 `/opt/prompt`。既有 `prompt_postgres_data`、`prompt_objects`、`prompt_auth_data` 卷与数据库身份保留；应用更名不会重新创建一套空存储。Compose 应用服务改为 `waterfall-wiki` 和 `waterfall-wiki-worker`，镜像参数为 `WATERFALL_WIKI_IMAGE` / `WATERFALL_WIKI_TEST_IMAGE`。
