…ap (#156) Cross-Router (#149, @JiaHg) merged and evaluated: Arena 73.71, Accuracy 75.13, Cost/1K $0.26, Opt 40.18/44.03/89.58, Robustness 59.05. Enters at #4 (between AgentForge and Weave); ranks 5-23 shift down one. Numbers are the official /evaluate metrics; an independent adversarial audit reproduced Arena/Accuracy/Cost/Robustness exactly and found the submission genuine (real inference, ground-truth exact-match 13.5%, valid token usage, real 420-row robustness file). Also adds the missing manifest entries for Cross-Router AND LLM Router (#139) so the website sync stops skipping them. Verified build_site_data.py regenerates 23 leaderboard rows including both.
