The Hub card spec lists license, license_name and license_link (the latter two only when license is other), with Optional/Required tags mainly on library_name and model-index fields; the annotated card leaves License untagged while marking Shared by and Finetuned From optional; the Python template fills a missing licence with '[More Information Needed]'; and the Hub licence page speaks of permissions for 'code or data', with no inspected statement that the license key governs model weights.
