CAROB: A Benchmark for Cross-Artifact and Authority-aware Reasoning over Organizational Bundles

Abstract
Enterprise AI assistants suffer from two failure modes not captured by existing public-web QA benchmarks: authorized information leakage, where factually correct answers reach unintended readers, and aggregation failure, where evidence scattered across artifacts yields fluent but incomplete responses. Both stem from enterprise authority being per-item and partly body-embedded, a structure that existing benchmarks address along at most one axis. We argue that authority-aware evaluation must be conducted at the per-item level, and instantiate this principle through Cross-Artifact and Authority-aware Reasoning over Organizational Bundles (CAROB): a synthetic enterprise dataset in which every retrieval-and-citation item carries a time-indexed audience/approval/lifecycle annotation, paired with three tasks that decouple cross-artifact coherence, authority-aware retrieval, and role-conditioned answering. Evaluating five frontier and open-weight LLMs, we find that no single model dominates both axes of the benchmark: each task induces a distinct model ordering, and the model strongest on authority handling ranks last on answer coverage. Two structural patterns hold across the lineup: retrieval-side leakage amplifies substantially at the answer stage, and structural authority filtering eliminates the residual leak band that prompt-level mitigation leaves behind, with both patterns replicating on EnronQA and ACCESS DENIED INC. We release CAROB as an evaluation testbed for authority-aware enterprise system design, together with its per-item annotation, three-task structure, and label-first generation pipeline as reusable infrastructure.
