Facet averages, against the whole catalog
| Facet | This cohort | Catalog | Difference | Scored |
|---|---|---|---|---|
| Operational Transparency | 21.9 | 11.3 | +10.6 | 29 |
| Contract Quality | 22.2 | 17.5 | +4.7 | 29 |
| Contract Governance | 9 | 6.4 | +2.6 | 29 |

| Access Clarity | 14.2 | 22.3 | -8.1 | 29 |
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.

mcp_pct counts any mcp/ artifact including ones API Evangelist derived from the provider OpenAPI; mcp_first_party_pct counts only servers the provider publishes. Prefer the latter.
