Facet averages, against the whole catalog

Facet	This cohort	Catalog	Difference	Scored
Access Clarity	34.4	22.3	+12.1	137
Discoverability	63.1	60.4	+2.7	137
Developer Ergonomics	20.4	17.9	+2.5	137

Contract Quality	18.1	17.5	+0.6	137
Contract Governance	5.9	6.4	-0.5	137

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.
