+Subject: [PATCH] pyproject: ship licence files of bundled libraries
+
+The Linux wheels bundle OpenBLAS (BSD-3-Clause), whose binary
+redistribution clause requires its copyright notice to travel with the
+binary, but the wheel only carries SCS' own LICENSE.
+
+Declare the licence files with a glob so any LICENSE.<dep> staged beside
+the project's own LICENSE is packaged into dist-info/licenses/. PEP 639
+rejects `project.license-files` while `project.license` is a table or a
+`License ::` classifier is present, so both are converted at the same
+time.
+
+Upstream-Status: To upstream [needs a companion CI change staging the licence text of each bundled library]
