The scripts look okay now, but the logs are showing some error codes.

I'm not sure why these aren't causing the job to fail. It's possible that the doxygen command is still exiting with 0 despite these errors.

Regardless, we should investigate and try to get them fixed.

The entire job log should be scanned for additional error messages besides the ones explicitly shown below.

Awesome! All looks good to me.

Two follow-up tasks for developers to address in separate PRs:

• drop usage of recommonmark because the repo is archived (in favor of MyST) and it's throwing warnings: parser: multiple warning messages due to missing visit_document() method readthedocs/recommonmark#177
• fix the most obvious warnings in the C++ docs (mislabeled parameters, etc.)
