  "title": "Historical accepted-work test across two provider families",
  "summary": "A confirmation run on 6 September 2026 completed one bounded coding fixture through each of two live provider families. The initial attempts failed; later attempts produced accepted artifacts after independent checks. Seven checks passed, including complete-job accounting. Publication was limited to a scoped authorization: no external pull request was created. A negative control showed that verifier independence mattered. The sample is two task arms with deliberately constrained initial attempts, not a general task-success rate, comparative model ranking or cost-savings claim.",
