Facet averages, against the whole catalog

Facet	This cohort	Catalog	Difference	Scored
Access Clarity	27.3	26.5	+0.8	150
Contract Governance	3.8	6.4	-2.6	150
Discoverability	57.9	61.2	-3.3	150

Contract Quality	9.1	19.8	-10.7	150

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.
