    "body_text": "Researchers used an agentic coding workflow to profile and refactor Python for simulation-based project scheduling on high-performance computers. Correctness checks kept outputs unchanged while test runtime fell from 1,298 seconds to under 200. The authors estimate four million core-hours and NZ$320,000 in annual savings for their workload. That is a documented case study with human control, not evidence that autonomous refactoring will safely optimize arbitrary scientific software.",
