Facet averages, against the whole catalog

Facet	This cohort	Catalog	Difference	Scored
Discoverability	66	60.4	+5.6	189
Operational Transparency	14.9	11.3	+3.6	189
Access Clarity	24.3	22.3	+2	189

Contract Quality	1	17.5	-16.5	189

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.
