docs(huya): 逆向定位 32hex hdid = NativeEntry.getGUID() + 真机注入通道证据

核心结论: - 32hex hdid (WUP 登录帧 field1.tag0) = com.huya.security.hydeviceid.NativeEntry.getGUID() - 金样本 ed0db8 为金样本设备 GUID; 当前真机 M2102J2SC getGUID()=0a7dfaa882938a6ab502511452142c57(稳定) - NativeEntry 全字段: getGUID(32hex)/getCDID(40hex)/getHDID(40hex)/getMID(16hex)/getSDID(base64 safedeviceid) - 单机不可铸造: 改 serialno/ANDROID_ID/删files/hydevice持久化均不变(硬锚底层硬件) - libhydeviceid.so 为 OLLVM+datadiv 壳; 用 dlopen->JNI_OnLoad->RegisterNatives(env表索引215) 绕开混淆脚本: phone_probe_registernatives2(注册表)/phone_java_call_nativeentry(Java读getGUID)/phone_read_hdid(native hook) phone_dump_hydev(dump解密so)/phone_probe_login_frame(登录帧)/arm64_disasm(反汇编) 证据: hdid_regtable/java_nativeentry/hdid_read/login_frames/hdid_probe* + libhydeviceid_{original,dump}.so
