The Architecture of Errors: From Universal Impossibility to Patch-Local LLM Reliability

arXiv CS.AI

ArXi:2605.30628v1 Announce Type: cross Universal LLM reliability is not a finite-library problem: across all possible tasks, tools, schemas, knowledge sources, and evaluator expectations, new intervention-distinguishable failure modes can appear without bound, so no finite intervention dictionary can guarantee bounded residual error for every such mode. But deployed systems do not operate over the whole universe.
