"""虎牙多账号设备画像生成与管理。
|
||
|
||
为每个账号生成并持久化独立的设备身份画像（机型、屏幕、指纹、设备ID等）。
|
||
|
||
注意：画像只承载 *soft* 设备字段（机型/屏幕/随机指纹/随机 device_id）。
|
||
``safedeviceid``（RSA action 令牌）与登录帧 ``device_id`` 由
|
||
:mod:`core.huya.dfp_register` 在每次 WUP 登录前经新设备注册链实时签发，
|
||
不再写入画像，也不再允许任何固定金样本令牌被多账号复用。
|
||
|
||
⚠ 字段状态速览（详见 ``docs/HUYA_APP_OVERVIEW.md`` §四）：
|
||
- 随机: fingerprint / 机型 / 屏幕 / 宽高 / device_id(画像侧)；
|
||
- 固定: hdid(32hex 硬锚，全账号同一) / app_version / sdk_version；
|
||
- 动态签发: safedeviceid、登录帧 device_id。
