Facet averages, against the whole catalog

Facet	This cohort	Catalog	Difference	Scored
Access Clarity	26.7	22.3	+4.4	131
Contract Governance	8.9	6.4	+2.5	131
Discoverability	60.8	60.4	+0.4	131

Contract Quality	12.4	17.5	-5.1	131

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.
