Unified routing (baseline mode) beats LMetric E2E mean/p50/p90. PD-sep offload consistently degrades performance (5-134 offloads tested). Independent review: fair comparison, no reward hacking, needs multi-run significance verification (running 3x paired test). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Approach A (contention-aware cost model): TTFT p90 -52% vs baseline. Approach B (session migration): 0 triggers at 1.5x threshold — needs tuning. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
