- 删除 operit_py/ (47个脚本)、operit_runtime.py、android_compat.py
- 新增 operit_loader.py — 通过 Android-pyApi 仓库提供 Android API 转译
- operit 脚本工具现通过 Android-pyApi (212模块/175K行) 无损运行
- 支持 Tools.System/Files/Net/UI/Memory/FFmpeg/Workflow/Chat/SoftwareSettings/Tasker
- 支持 OkHttp/console/complete/exports 全套 Operit API
- 跨平台运行: Windows/macOS/Linux
