## Headline

with_skill **0.880 ± n/a (1 case)** vs baseline **0.578 ± n/a (1 case)**

skill lift **+0.302** (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 | 0.880 ± 0.006 | Explicit Critical/Required/Nit labels on every finding, hardcoded secret Critical, PII logging Critical, `data` name Nit, ordered by leverage with concrete fixes; not quite flawless-exceptional. |
| `severity-labeled-findings` | baseline | borderline ⚠ | 0.578 ± 0.146 | Explicit severity labels on every finding with secret and PII logging as Critical and leverage-ordered, but no low-severity finding at all — the `data` naming nit is absent. |
