A <5ms step classifier (AgentRouter) dispatches routine tool/parsing steps directly to c_S and hard synthesis directly to c_F without paying c_S twice (~72% cost cut at 97.3% frontier accuracy). | Fresh Preprints: https://andygrove.systems/preprints | 42-Hr CPD Hub: https://andygrove.systems/education (Independent platform; not affiliated with Intel Corporation or the Grove family)
