-# 系统种子用户 Migration
-
-## 目的
-
-创建一个系统种子用户，用作根推荐人，解决"第一个用户无法注册"的问题。
-
-## 种子用户信息
-
-- **User ID**: `1` (固定ID)
-- **Account Sequence**: `SYSTEM00001`
-- **推荐码**: `GENESIS`
-- **昵称**: `系统`
-- **状态**: ACTIVE
-- **手机号**: NULL（系统用户不需要手机号）
-
-## 使用方式
-
-第一批用户在注册时，使用推荐码 **GENESIS** 即可完成注册。
-
-## 特点
-
-1. ✅ 保持了推荐码必填的业务逻辑
-2. ✅ 所有用户都有完整的推荐关系链
-3. ✅ 系统用户只提供推荐码功能，不参与其他业务
-4. ✅ 使用固定 UUID，方便识别和管理
-
-## 注意事项
-
-- 此用户不应该被删除
-- 此用户不能登录（没有手机号和密码）
-- 此用户的推荐码 `GENESIS` 可以被无限次使用
