 一个本地单机视频生成 Worker，提供最小化 HTTP API：接收任务、按模式路由模型、单任务串行执行、输出统一结果目录。
 
+## 项目拆分（推荐部署方式）
+
+已拆分为两个可独立部署的目录：
+
+- `center_dispatch/`：中央调度项目（HTTP 管理 + WS 下发）
+- `edge_node/`：边缘执行项目（本地推理 + 主动连中心）
+
 ## 1. 项目说明
 
 - 目标：边缘执行节点，不是完整平台。

+# Center Dispatch Project
+
+中央调度服务独立项目目录，仅负责：
+
+- 设备接入（`WS /ws/edge/{device_id}`）
+- 上游 HTTP 下发任务（`POST /dispatch/generate`）
+- 上游 HTTP 下发运维指令（`POST /devices/{device_id}/command`）
+- 指令/任务状态查询（`GET /dispatch/{id}`、`GET /commands/{id}`）
+
+## Quick Start
+
+```bash
+cd center_dispatch
+bash scripts/start.sh
+```
+
+停止：
+
+```bash
+bash scripts/stop.sh
+```
+
+## Notes
+
+- 首次运行会生成 `.env`，请至少配置：
+  - `GIT_REPO_URL`（开启 `AUTO_PULL_LATEST=true` 时必填）
+  - OSS 相关配置（`OSS_ENABLED=true` 时必填）

+# Edge Node Project
+
+边缘设备独立项目目录（主动连接中心 WS，接收任务和运维指令）。
+
+安全边界：
+
+- 边缘仅主动连接中心（`DISPATCH_WS_URL`）
+- 边缘不提供外网入口，Worker 固定绑定 `127.0.0.1`
+
+## Linux / WSL
+
+```bash
+cd edge_node
+bash scripts/start.sh
+```
+
+停止与重启：
+
+```bash
+bash scripts/stop.sh
+bash scripts/restart.sh
+```
+
+## Windows PowerShell (WSL)
+
+```powershell
+cd edge_node
+.\scripts\wsl.ps1 -Action start
+```
+
+常用：
+
+```powershell
+.\scripts\wsl.ps1 -Action status
+.\scripts\wsl.ps1 -Action restart
+.\scripts\wsl.ps1 -Action stop
+```
+
+## Config
+
+首次启动会生成 `edge_node/.env`。请至少设置：
+
+- `DISPATCH_WS_URL=ws://<center-host>:8060/ws/edge/<device-id>`
+- `WORKER_BASE_URL=http://127.0.0.1:8000`
