OdysseyArena - Repo System (Pass@4): leaderboard

Metric: Success rate (%) with a task counted solved when any of four runs succeeds (Pass@4) on OdysseyArena-Lite (30 fixed tasks per environment; the agent must induce hidden transition rules from its own interactions; prompts keep past actions and feedback but not earlier reasoning; open models at temperature 0.6), environment Repo System: make a Python project run by installing and removing package versions under a hidden dependency graph, within 120 steps; rules hidden (the benchmark's inductive setting); higher is better.
