Facet averages, against the whole catalog

|---|---|---|---|---|
| Developer Ergonomics | 38.6 | 17.9 | +20.7 | 27 |
| Contract Quality | 32.8 | 17.5 | +15.3 | 27 |

| Contract Governance | 11.9 | 6.4 | +5.5 | 27 |
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.
