Facet averages, against the whole catalog

| Discoverability | 63.5 | 58.1 | +5.4 | 182 |

| Contract Quality | 0.4 | 17.6 | -17.2 | 182 |
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.
