| <h2>What this is</h2> |
| Three agents, one task, one conflict, one arbitrator. |
| Two frozen worker agents build the same spec in parallel. |
| A third agent (Agent C) sees both outputs plus the original spec, |
| decides who drifted, and stops the wrong one before merge fails. |
| Agent C is trained via GRPO on programmatic, contrastive rewards — |
| no LLM as judge, no hardcoded rules. |
