## Headline

with_skill **0.657 ± n/a (1 case)** vs baseline **0.573 ± n/a (1 case)**

skill lift **+0.085** (combined uncertainty ± n/a (1 case))

band rule: each arm's band is the sample stddev of its per-case means — per arm: the sample standard deviation (n-1) of the per-case means across the included cases; the comparison band is the quadrature sum of the two arms; null where an arm has fewer than two included cases

## Per-case (mean ± stddev over 3 judge samples)

| case | mode | outcome | mean ± stddev | judge reason |
|---|---|---|---|---|
| `severity-labeled-findings` | with_skill | borderline ⚠ | 0.657 ± 0.257 | Explicit Critical/Required/Nit labels on every finding, secret marked Critical, PII logging Critical, findings ordered by leverage with fixes; misses the cosmetic `data` naming nit. |
| `severity-labeled-findings` | baseline | borderline ⚠ | 0.573 ± 0.176 | Explicit severity labels on every finding, secret marked Critical, cosmetic naming last and ordered by leverage; PII logging only Medium and the `data` name nit is absent. |
