| # platform-correct address via tests/helpers/test_socket.h. | |
| # * GitReportToJson / CodeInsightGitTest / *HandlerFixture / | |
| # ExploreIndexTestFixture — depended on report_to_json's POSIX-shaped | |
| # path normalization (std::filesystem::relative treats a '/'-rooted | |
| # path as non-absolute on Windows). normalize_rel is now a purely | |
