Facet averages, against the whole catalog

| Contract Quality | 34.2 | 17.5 | +16.7 | 57 |

| Contract Governance | 12.1 | 6.4 | +5.7 | 57 |
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.
