Independent agents — working in parallel, no communication — amplified errors 17.2 times. Give the same agents a centralized hub-and-spoke topology, and error amplification dropped to 4.4 times. Same intelligence. Same training. A 3.9x difference in error rate, explained entirely by communication structure. This isn't a story about better prompts or s
