Facet averages, against the whole catalog
| Facet | This cohort | Catalog | Difference | Scored |
|---|---|---|---|---|
| Contract Quality | 37.4 | 17.5 | +19.9 | 26 |
| Developer Ergonomics | 32.6 | 17.9 | +14.7 | 26 |

| Contract Governance | 8.2 | 6.4 | +1.8 | 26 |
A facet is averaged over the members that carry it, not over the whole cohort — the “Scored” column is that count. Averaging an absent facet as zero would score our own coverage gaps as the providers’ posture.
