One Equation Governs CPU Caches, Human Teams, and AI Agent Systems
Eight agents complete a benchmark worse than four, at 2x the token cost. The equation that predicts this was written in 1993 for parallel databases — and it governs CPU caches, engineering teams, and AI swarms with identical math. This post proves it at all three layers, then hands you the instrument: given your measured alpha, kappa, and role error weights, compute the topology before you spawn the first agent.
