Facet averages, against the whole catalog

| Contract Quality | 35 | 17.5 | +17.5 | 193 |
| Developer Ergonomics | 32.6 | 17.9 | +14.7 | 193 |

| Contract Governance | 12.5 | 6.4 | +6.1 | 193 |
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.
