On OS X: the problems I reported before persist: many doctest failures, and the git repo is not clean after running ./bootstrap and ./configure (after doing a fresh "git clone ...").

For the latter, I suppose https://github.com/sagemath/sage/pull/40842
will fix it (needs review)

For doctest failures, well, one needs to see config.log, logs/test.log

I interact with Google groups via a website, not email, and I don't know how to attach files. As I said in the earlier thread:

Hi John,

That icon is not present in my web interface, unfortunately:

Strange.

Ah, an owner/manager of the group may have to allow posting attachments from the web

might be a "feature" of the browser you use.

Anyhow you can always open a GitHub issue, upload files there, and post a link to it here

Of these test results you report details of, the test is good to go, as we build sagelib with ninja now;

the last two  are indeed a concern, and the rest is just formatting/sorting fluff or a format change (I don't think added "<-R^0" for diagrams

is a maths issue)

Open an issue?
