**RESCUE: Is This Alarm Worth Acting On? Counterfactual Evaluation of VLA Runtime Monitors**

RESCUE通过恢复仿真器与策略检查点做反事实比较，评估VLA监控警报是否能在LIBERO任务上降低完成成本。

## 核心要点

- 传统监控评估只看区分失败与成功，但警报过晚或不必要干预都可能降低实际价值。
- RESCUE在执行检查点恢复仿真器和策略状态，比较替代动作并寻找满足恢复准则的最晚检查点。
- 论文用OpenVLA-OFT和π0.5在LIBERO-Spatial与LIBERO-Plus上评估128,340个反事实分支。
- 结果显示可恢复性取决于状态—干预组合，良好检测分数并不必然带来更低干预成本。

**验证范围与局限**：验证范围限于上述策略与LIBERO任务中的仿真反事实分支，以及所评估的停机重置干预模型。

## 英文摘要 (Abstract)

Runtime failure monitors for robot policies are typically evaluated by how accurately they distinguish failed from successful executions. Yet an accurate alarm may arrive too late for recovery, while an unnecessary intervention may disrupt an execution that would otherwise succeed. We introduce RESCUE, a counterfactual framework for evaluating whether a monitor's alarms enable useful interventions. By restoring simulator and policy states at execution checkpoints, RESCUE compares alternative actions, identifies the latest checkpoint satisfying a specified recovery criterion, and evaluates whether acting on alarms reduces expected task-completion cost. We evaluate RESCUE with OpenVLA-OFT and $π_{0.5}$ over LIBERO-Spatial and LIBERO-Plus using 128,340 counterfactual branches. Recoverability depends on the state--intervention pair rather than on robot state alone: at $τ=0.5$, 14 of 66 OpenVLA-OFT/LIBERO-Plus failures contain a recoverable checkpoint under continuation, compared with 34 of 66 under continuation or scripted recovery, while recovery reduces recoverability in other conditions. On the primary strong-policy conditions, favourable detection scores do not establish lower intervention cost. Under the evaluated stop-and-reset model, even an idealised detector can afford only a 2.0--3.3% false-alarm rate before unnecessary resets outweigh the savings from stopping failures early. These results show that monitor value depends jointly on the intervention available and the workload in which it is deployed.
