# SDL-2 leaderboard

Ranked by Both. **Both:** the final claim is right in the world and the agent's own evidence supports it (a restriction measured routes among the world's 100 nearest to passing and every such loop failed; a nomination passed on two bodies of the route). **Material outcome:** on the feasible worlds, the agent nominated an exact process that meets 10 kOe and 11 MGOe. **Credits to a supported decision:** among its Both-correct episodes, the credits spent until its final claim was supported (114-credit steps; allowance 570). Exact 95% intervals in RESULTS.json.
