Confidence

95% bootstrap interval on recall (2000 resamples over the 30 PRs):26.4–47.9points. This measures sampling variance from which PRs are in the set.

Judge noise (same submission, 3 independent re-scores): recall36.8 ± 0.0pts (n=3). This is the judge alone — the exact same findings, scored again.

Neither measures model run-to-run variance — re-running the review agent itself, not just the judge. One pass per entry.
