Facet averages, against the whole catalog
| Facet | This cohort | Catalog | Difference | Scored |
|---|---|---|---|---|
| Access Clarity | 42.9 | 26.5 | +16.4 | 79 |
| Developer Ergonomics | 37.4 | 23.4 | +14 | 79 |
| Contract Quality | 32.5 | 19.8 | +12.7 | 79 |

| Discoverability | 67.6 | 61.2 | +6.4 | 79 |
| Contract Governance | 12.2 | 6.4 | +5.8 | 79 |
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.
