Facet averages, against the whole catalog
| Facet | This cohort | Catalog | Difference | Scored |
|---|---|---|---|---|
| Developer Ergonomics | 26.3 | 17.9 | +8.4 | 77 |
| Contract Quality | 25.2 | 17.5 | +7.7 | 77 |
| Access Clarity | 29.7 | 22.3 | +7.4 | 77 |
| Operational Transparency | 18 | 11.3 | +6.7 | 77 |
| Discoverability | 65.2 | 60.4 | +4.8 | 77 |
| Contract Governance | 10.3 | 6.4 | +3.9 | 77 |
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.
