## Headline

with_skill **0.566 ± n/a (1 case)** vs baseline **0.547 ± n/a (1 case)**

skill lift **+0.019** (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 | fail | 0.566 ± 0.111 | Explicit severity labels throughout, secret correctly Critical, `data` name Optional, findings ordered by leverage; but PII console.log miscalibrated as Optional rather than Required/Critical (-0.2). |
| `severity-labeled-findings` | baseline | borderline ⚠ | 0.547 ± 0.190 | Secret flagged under a Critical heading, but severity is only coarse section grouping; PII logging demoted to "Other Issues", error/promise issues miscalibrated as Critical security, and the cosmetic `data` name Nit omitted entirely. |
