Facet averages, against the whole catalog

|---|---|---|---|---|
| Contract Quality | 43.5 | 17.5 | +26 | 33 |
| Developer Ergonomics | 33.3 | 17.9 | +15.4 | 33 |

| Operational Transparency | 14 | 11.3 | +2.7 | 33 |
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.
