Facet averages, against the whole catalog

|---|---|---|---|---|
| Contract Quality | 26.2 | 17.5 | +8.7 | 659 |
| Discoverability | 68.5 | 60.4 | +8.1 | 659 |

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.
