| ### The Problem | |
| **40,000+ patients** die annually from diagnostic errors [(Johns Hopkins, BMJ 2016)](https://www.hopkinsmedicine.org/news/media/releases/study_suggests_medical_errors_now_third_leading_cause_of_death_in_the_us). | |
| As AI deploys in clinical trials: **Who audits the AI?** | |
| ### Our Solution | |
| An **Oversight Agent** trained with GRPO learns to catch errors from an **Actor Agent**. | |
| 8 tools, multi-step reasoning, Theory-of-Mind scoring β all through pure RL. | |
| ### Key Results | |
| - **283% improvement** over untrained baseline | |
| - **4Γ more clinical errors** correctly detected | |
| - **Free Colab T4** β trained in 2h 20m on 15.6 GB VRAM | |
| - **200 GRPO steps** in 2 hours 20 minutes | |
