TClone让电脑代理在不中断操作的情况下快速分叉工作区，提升安全与效率。
TClone: Low-Latency Forking of Live GUI Environments for Computer-Use Agents
- 通过内存共享和文件系统版本化实现毫秒级工作区分叉
- 相比KVM和CRIU，任务总延迟降低1.9倍和1.5倍
- 适合需要高并发试错的智能代理应用
计算机使用代理越来越多地运行在用户实时工作环境中，其操作可能修改文件、应用、GUI状态、凭据和已认证会话。这带来安全与质量之间的矛盾：代理需要隔离与回滚以避免破坏用户状态，又需快速分叉以支持推测执行和并行搜索。现有虚拟机、容器及检查点/恢复系统虽能隔离或恢复负载，但无法提供全交互工作区的低延迟版本管理。我们提出TClone，一种可分叉的个人工作区系统，支持活态GUI工作区的快照、分叉为独立分支、回滚及选择性提交或合并。其设计将快速分叉与持久检查点分离，采用兄弟容器、写时复制内存共享、文件系统版本化、GUI本地执行和异步检查点。在端到端代理循环测量中，TClone相比KVM和CRIU分别将任务总延迟降低1.9倍和1.5倍。通过将工作区版本化作为系统原语，TClone实现了真实个人计算环境下的更安全、更高品质的代理执行。
原文摘要 · Abstract (English)
Computer-use agents increasingly operate inside live personal workspaces, where their actions can modify files, applications, GUI state, credentials, and authenticated sessions. This creates a tension between safety and quality: agents need isolation and rollback to avoid damaging user state, but also need fast branching to support speculative execution and parallel search. Existing VMs, containers, and checkpoint/restore systems can isolate or recover workloads, but they do not provide low-latency versioning of a full interactive workspace. We present TClone, a forkable personal workspace system for computer-use agents. TClone enables a live GUI workspace to be snapshotted, forked into isolated branches, rolled back, and selectively committed or merged. Its design separates fast branch creation from durable checkpointing, using sibling containers, copy-on-write memory sharing, filesystem versioning, GUI-local execution, and asynchronous checkpointing. In our end-to-end agent-loop measurement, TClone reduces total task latency by 1.9x and 1.5x over KVM and CRIU. By making workspace versioning a first-class systems primitive, TClone supports safer and higher-quality agent execution over real personal computing environments.
