Facet averages, against the whole catalog

|---|---|---|---|---|
| Access Clarity | 34.3 | 22.3 | +12 | 37 |
| Developer Ergonomics | 27.9 | 17.9 | +10 | 37 |

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.
