Source files keep their SPDX-License-Identifier and Hanzo copyright line; the Gitea, Gogs and LFS Test Server copyrights they used to repeat now live once in NOTICE, alongside LICENSE. The header lint accepts any copyright line above the SPDX line, so it no longer demands an upstream one. Co-authored-by: Hanzo Dev <[email protected]>
