     - Response:
     - `projectCount`: count of distinct projects in the collection.
     - `uniqueContributorCount`: total unique contributors across all projects in the collection, deduplicated (a contributor active on multiple projects in the collection is counted once).
-    - `avgHealthScore`: average of each project's health score in the collection, rounded.
+    - `avgHealthScore`: average health score across the collection's onboarded projects, rounded. A project
+      is "onboarded" when it has at least one contributor or organization attributed to it (same definition
+      used by insightsProjects_filtered.pipe's `onboarded` filter and the frontend's project-row `isOnboarded`
+      check) — projects with no attributed contributors/organizations have no meaningful health signal yet
+      and would otherwise pull the average down artificially.
