/*
  预置 60 个特殊实验账号（尚未完成首次验证码登录）
  - A 组：A001@lyrria.com ~ A030@lyrria.com
  - B 组：B001@lyrria.com ~ B030@lyrria.com

  前置条件：
  1. 已执行 add_special_user_fields.sql
  2. users 表已存在（含 user_segment、is_test_user 等字段）

  账号状态说明：
  - user_type = guest，is_verified = 0，registered_at = NULL
  - 邮箱已占用，防止被其他用户注册
  - 首次验证码登录时，后端需识别「guest + is_special_user」并完成注册化
    （后续改造 verify_and_auth / register_with_email 时处理）

  幂等：按 email 冲突时仅更新特殊用户标记，不覆盖已注册用户数据
