Facet averages, against the whole catalog

|---|---|---|---|---|
| Contract Quality | 62 | 17.5 | +44.5 | 35 |

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.
