Facet averages, against the whole catalog

|---|---|---|---|---|
| Contract Quality | 29.5 | 17.5 | +12 | 57 |
| Developer Ergonomics | 25.2 | 17.9 | +7.3 | 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.
