All PD/offload schemes tested are worse than PD-combined + hybrid routing: Combined hybrid: TTFT=0.737 TPOT90=0.072 APC=49.4% (BEST) PD-Sep 4P+4D: TTFT=1.994 TPOT90=0.075 APC=40.2% Adaptive v2 offload: TTFT=1.462 TPOT90=0.077 APC=~45% Definitive: single-machine agentic serving = PD-combined + smart routing.
