      The documentation of QTemporaryFile::rename() (https://doc.qt.io/qt-6/qtemporaryfile.html#rename) neglects to say whether the function will overwrite the target, if it exists.

      It seems it doesn't (implementation calls QTemporaryFileEngine::rename(), not renameOverwrite()), making this function rather useless, seeing as it's the only public Qt API I know that guarantees an atomic rename of a file at the OS level.
