   Beyond the Verdict: Agentic Code Judging with Verifiable Feedback
   To evaluate this task, we build USACO-JUDGE from the USACO 2026 contests, using accepted and unaccepted programs written by human experts and multiple LLMs. We then train ARBITER, a 35B mixture-of-experts (MoE) agentic verifier, with reinforcement learning in a generic execution sandbox.

   MagicBeanStalk: Escaping the RLVR Zero Advantage Trap with Recursive Data Synthesis
