[D] Breaking down MiroThinker H1's verification centric reasoning: why fewer interaction rounds produce better agent performance

I've been building agentic RAG systems at work and keep running into the same problem: agents that spiral into long, unproductive tool call loops. So when I saw the MiroThinker paper (arXi: 2603.15726) claiming that their newer model achieves ~17% better performance with roughly 43% fewer interaction rounds compared to the previous generation, I wanted to understand the actual mechanism. The answer turns out to be their "verification centric reasoning" architecture, and I think it's the most interesting part of the paper. The system operates at two levels.
