  "title": "Do Coding Agents Understand Why Systems Crash---and Why They Don't?",
  "summary": "The method replaces single-version crash prediction benchmarks with paired source trees differing by one commit, so a correct-looking prediction on crashing code alone is no longer accepted as evidence of execution reasoning. It costs the construction of matched pre/post-commit tree pairs with a verified crash-triggering input (934 pairs here from Linux and OSS-Fuzz), plus roughly double the agent evaluation runs per case. It can fail if pairs are not truly minimal, if the crash input is flaky, or if agents refuse or time out on large systems codebases, and it measures crash reasoning only, not general bug-fixing ability.",
  "rationale": "For a team shipping coding agents on large codebases, adopting paired evaluation is a low-cost way to detect suspicious-pattern shortcutting before trusting agent crash or bug triage in production.",
