-- `original-license`: the license applicable to the original source
 - `source`: the URL from which the source data was obtained
+- `original-license`: the license associated with the original source data

+Because the records originate from datasets distributed under different licenses, this dataset is not distributed under a single uniform license.
 
-The original response text was stylistically rewritten by an LLM rather than generated independently from scratch.
+Users must comply with the applicable terms of the source license identified by `original-license`, to the extent those terms apply to the transformed material. Depending on the source, these terms may include attribution, preservation of notices, indication of modifications, non-commercial restrictions, ShareAlike requirements, or database-specific obligations.
 
-There is therefore no single license applicable to the entire dataset. Please refer to the `original-license` field of each record and comply with the corresponding license terms.
+Records originating from licenses that prohibit redistribution of modified material, such as CC BY-ND and CC BY-NC-ND, have been excluded from this dataset.
