![Trajectory-persistent adversarial attacks reveal that recurrent state space model (RSSM) architectures amplify initial perturbations-increasing by a factor of 2.26× in the deterministic GRU world model-before GRU contraction attenuates them, a phenomenon not observed in single-step baselines, and which is mitigated through adversarial fine-tuning-reducing amplification across all steps-resulting in a reward gap of only [latex]0.000892 \pm 0.000057[/latex] at a planning horizon of 30, and demonstrating a fundamental trade-off between model expressiveness and robustness to adversarial input.](https://arxiv.org/html/2604.01346v1/x1.png)
