The analysis is completely wrong.

The offending patch is [1]. I assume the reason for the failure is that gap between when the CI passed (Nov 21) and when it was merged (Nov 26). In the five days in between, other patches entered master and invalidated this CI result.

To quote the job's log:

I noticed this by chance yesterday and merged [2] (which is listed as the probable cause here, of all things!) to fix it.

Once the change queue catches up to this, you should be OK.
