+Subject: [PATCH] pyproject: list vendored C++ licence files in
+ [project].license-files
+
+protovalidate._protovalidate statically links six vendored C++ projects
+(abseil-cpp, antlr4, cel-cpp, protobuf + its bundled utf8_range, re2,
+protovalidate-cc) compiled from crates/protovalidate-rs/build.rs, but
+[project].license-files only names the package's own root LICENSE.
+maturin has no default glob for a PEP 639 project (gotcha 105/146 in
+this repo's porting skill), so every published wheel - on every
+platform, not just riscv64 - ships none of the six licence texts the
+compiled binary actually requires. All six are permissive (Apache-2.0
+x3, BSD-3-Clause x3 for protobuf/antlr4/re2, plus utf8_range's MIT),
+so this only adds licence-files entries; no GPL text is involved.
+
+Upstream-Status: To upstream [not submitted: this session's policy is to not open issues/PRs on third-party repos]
