- 账号导入：支持'账号----密码----手机号----接码链接'四段式解析与持久化存储
- 旋转验证码 (rotate_auth / xz)：逆向分析官方协议，基于圆周边界采样互相关算法秒级计算旋转还原角度
- 文本点选验证码 (dx_auth)：内置成语与古诗名句语料，支持题干菜名提取与古诗/成语挖空正则求解及小图动态合成
- 短信二次验证 (sms_auth2)：结合 sms_url 自动轮询接码链接并 Hex 编码提交官方过验
- 前端交互：增加接码标签、在线查询短信验证码、一键自动短信登录与测试接码链接功能
- 回归测试：新增旋转验证、短信接码流与文本点选测试用例（173 passed）
