A Universal Cliff and a Design Fingerprint: Cross-Section Defect Detection Under LLM Orchestration
arXiv:2605.26174v1 Announce Type: cross Abstract: Production language-model systems answer a request by partitioning it across an invisible orchestration of worker agents that recompose one integrated report. We ask what this does to a class of defect no single worker can see: a contradiction in the relation between two distant sections of a document. Holding the documents, defects, mechanism, scoring, and seed fixed, we vary only the model -- ten systems across five generations from one developer and five providers from distinct alignment paradigms. Two layers separate. First, a universal det
The paper addresses a critical emerging challenge as large language models (LLMs) become increasingly integral to complex, multi-agent workflows across various industries.
It highlights a fundamental defect class (cross-section contradictions) inherent in orchestrated LLM systems, which can undermine reliability and trust in their outputs at scale.
Understanding these architectural failure modes will drive new engineering practices and model development paradigms focused on orchestration and consistency in AI agent systems.
