@@ -2,7 +2,6 @@ DESCRIPTION >
     - `activities_enriched.pipe` provides a filtered and optionally paginated view of activity relations, then enriches those rows with content fields from the activities dataset.
     - This pipe powers endpoints that need both relation metadata and activity content (url/body/title) without performing a full join on large tables.
     - It filters from `activityRelations_deduplicated_ds` by project segment, time ranges, repositories, platforms, and activity types, then joins only the small, filtered set against `activities_deduplicated_ds`.
-    - By default, this pipe returns only contribution activities (`isContribution = 1`) unless explicitly overridden with `onlyContributions = 0`.
     - Security / scoping: if you use a `segments_filtered` pipe in your environment, replace the `segmentId` filter to read from it (see comment in Node 1).
     - Parameters:
     - `segments`: Optional array of segment IDs (e.g., ['7c3f6874-b10e-499b-a672-00281ab6c510']). If you use `segments_filtered`, remove this and rely on that pipe.
