Welcome back, and thanks for trusting me to keep the patches moving
between integration branches while you were gone.

Now that we are no longer referring to my tree here to list the
broken-out topics, I have cleaned out topics besides my own that would
ordinarily reside in this tree.

This is marked as "Graduated to 'master'", although I suspect it isn't.
I thought that it would have been because the topic went away, although
I still see this in 'jch' via your 3503a15e17 (Merge branch
'kh/bundle-docs' into jch, 2024-11-03).

Perhaps this WC report was generated before moving the topic back into
'jch'? In either event, as noted by <ZyUqr/wb5K4Og9j9@nand.local>, this
topic is still under discussion and is not ready to be merged (yet).

This topic was ejected, which is fine since it hasn't seen any review in
a few weeks. It's on my list of things to resend.

Ditto.
