Facet averages, against the whole catalog
| Facet | This cohort | Catalog | Difference | Scored |
|---|---|---|---|---|
| Contract Quality | 33.6 | 17.5 | +16.1 | 54 |
| Developer Ergonomics | 29.6 | 17.9 | +11.7 | 54 |

| Operational Transparency | 16.3 | 11.3 | +5 | 54 |
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.
