Stanford study finds harness evolution hits a ceiling for agents

A Stanford paper (arXiv:2610.11655) shows that agent harness evolution has a ceiling, and when failures stem from content rather than planning, weight training is the key lever. LoRA fine-tuning reduced the failure rate to 1/20 in their experiments.
