Facet averages, against the whole catalog
| Facet | This cohort | Catalog | Difference | Scored |
|---|---|---|---|---|
| Contract Quality | 44.3 | 17.5 | +26.8 | 447 |
| Developer Ergonomics | 38.4 | 17.9 | +20.5 | 447 |

| Contract Governance | 13.9 | 6.4 | +7.5 | 447 |
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.
