arXiv:2606. 06660v1 Announce Type: new Abstract: Long-horizon robot manipulation tends to fail gradually: one bad step degrades the state, and the policy spirals into a basin from which it cannot recover.

The paper introduces RESCUE, a counterfactual framework that evaluates whether runtime monitors for robot policies generate alarms that lead to useful interventions. By restoring simulator and policy states at checkpoints, RESCUE compares alternative actions to identify the latest checkpoint that satisfies a recovery criterion and measures whether acting on alarms reduces expected task‑completion cost. Experiments on OpenVLA‑OFT and π0.5 over LIBERO‑Spatial and LIBERO‑Plus show that recoverability depends on the state–intervention pair, and that even an ideal detector can only tolerate a 2.0–3.3% false‑alarm rate before unnecessary resets outweigh early failure stops.
Software engineering (SWE) agents resolve repository-level issues through long trajectories that grow increasingly expensive as context accumulates. Failed runs tend to be longer and exhibit redundant exploration or looping, suggesting that some failures may be detectable before completion.
The paper investigates Observation‑Space Shift (OSS), a failure mode in long‑horizon robotic manipulation where downstream skills start from states altered by preceding skills. By diagnosing that displaced scene elements—not robot joints or target objects—cause most OSS, the authors develop a detect‑restore‑resume system that monitors task progress, restores the scene, and fine‑tunes the skill to resume. On the BOSS‑44 benchmark, this approach raises full‑chain success from 7.6 % to 26.5 %, outperforming several baselines and demonstrating the value of scene restoration before policy resumption.
