+Subject: [PATCH] Widen license-files to cover bundled third-party licences
+
+`license-files = ["COPYING-LGPL", "COPYING-MIT"]` is an explicit PEP 639
+list, so it replaces setuptools' default `LICEN[CS]E*` glob rather than
+adding to it: a `LICENSE.<dep>` dropped at the project root to cover a
+library `auditwheel repair` vendors into the wheel (libcurl and its
+transitive closure) is silently ignored. Widening the list to also match
+`LICENSE.*` picks those up with no other packaging change.
+
+Upstream's own manylinux wheels vendor a smaller set of the same libraries
+(via a statically-built vcpkg curl) and carry the identical gap: only
+COPYING-LGPL/COPYING-MIT ship in dist-info/licenses, with no notice for
+libcurl, OpenSSL, krb5, libssh2, brotli or nghttp2.
