CockpitHAT: Dependency-Graph-Driven Hierarchical Attribution for Embodied Multi-Agent Cockpits

CockpitHAT is a hierarchical attribution framework for embodied multi‑agent systems that replaces positional windows with dependency‑distance thresholds derived from interaction DAGs, incorporates multi‑channel evidence through an embodied adapter, and applies a safety‑uplift to high‑risk failures during confidence‑weighted analyst consensus. The authors also release CockpitBench, a benchmark of 212 annotated failure traces labeled with ISO 26262 ASIL severity. On both the public Who&When benchmark and CockpitBench, CockpitHAT outperforms the text‑only state‑of‑the‑art ECHO, achieving higher agent‑level and step‑exact accuracies across multiple splits.
