Facet averages, against the whole catalog

|---|---|---|---|---|
| Operational Transparency | 30.1 | 11.3 | +18.8 | 44 |
| Contract Quality | 31.5 | 17.5 | +14 | 44 |

| Contract Governance | 9.6 | 6.4 | +3.2 | 44 |
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.
