  "title": "Coaching Qwen3 Coder 30B to Think Like a CodeClash Arena Agent",
  "summary": "The method replaces vanilla offline SFT on raw teacher traces with SFT over teacher trajectories rewritten into explicit observation-thought-action chains, plus sample reweighting that favors post-edit verification behavior. The cost is access to strong-agent teacher trajectories from the target environment, trajectory rewriting, and fine-tuning capacity for a 30B model, which exceeds a single 24 GB GPU without aggressive quantization and is easier via rented compute. It can fail when teacher behavior does not transfer to the reader's task distribution, when rewritten chains teach superficial reasoning formats, and because the gains are demonstrated only in one arena-style benchmark, not general coding workloads.",
  "rationale": "The idea is sound but adopting it requires 30B-scale fine-tuning and environment-specific teacher data that the reader's constrained infrastructure and budget do not readily support, so it should be monitored rather than adopted or tested now.",
