Facet averages, against the whole catalog

|---|---|---|---|---|
| Developer Ergonomics | 58 | 23.4 | +34.6 | 30 |
| Contract Quality | 50 | 19.8 | +30.2 | 30 |

| Discoverability | 70.5 | 61.2 | +9.3 | 30 |
| Contract Governance | 15.7 | 6.4 | +9.3 | 30 |
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.
