  "message": "fix: returning a copyable type with a deleted move constructor (#6143)\n\n* fix: returning a copyable type with a deleted move constructor (#6142)\n\ndetail::function_ref\u0027s constructor SFINAE required\nis_convertible\u003cRet, Ret\u003e, which is false for a copyable type whose move\nconstructor is explicitly deleted (the trait tests conversion from an\nxvalue). In C++17, such a prvalue return is legal via guaranteed copy\nelision, so also accept an exact type match. Regression introduced in\n3.1.0 by the call_impl outlining (#5887).\n\nFixes #6142\n\nAssisted-by: ClaudeCode:claude-fable-5\n\n* refactor: guard with __cpp_guaranteed_copy_elision\n\nPer review: the feature-test macro expresses the intent more precisely\nthan PYBIND11_CPP17.\n\nAssisted-by: ClaudeCode:claude-opus-5",
