## Headline

with_skill **0.861 ± n/a (1 case)** vs baseline **0.813 ± n/a (1 case)**

skill lift **+0.048** (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 | pass | 0.861 ± 0.068 | Explicit Critical/Required/Nit labels on every finding, secret as Critical, PII as Required, `data` as Nit, ordered by leverage with a concrete fix per finding. |
| `severity-labeled-findings` | baseline | pass | 0.813 ± 0.076 | Explicit severity tiers, secret correctly Critical, PII logging High, ordered by leverage with concrete fixes; uses High/Low instead of Required/Nit and omits the `data` naming nit. |
