A document source has a license that forbids the proposed commercial redistribution. What should the team do before adding it to a customer-facing RAG application?

1. Obtain appropriate rights or replace the source with material permitted for the intended use.
2. Embed it first because vectors automatically remove all usage restrictions.
3. Rely on a prompt telling the model that every source is public domain.
4. Remove the author's name and treat the content as unrestricted.
