Facet averages, against the whole catalog

|---|---|---|---|---|
| Developer Ergonomics | 46.9 | 23.2 | +23.7 | 35 |

| Contract Governance | 9.2 | 6.3 | +2.9 | 35 |
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.

All 35 members of this roster resolve to a scored provider in
the catalog.Generated from the catalog build of
5 October 2026, across 29093
providers, using the same computation served by the
APIs.io cohort API. Briefs are published for rosters of
5 or more scored providers; below that a distribution is not meaningful.
