@jkuester could you give this a brief look when you have time? I made some changes in the view to simplify the code (like iterating over the include keys instead of each document object keys) and I'd like a sanity check to make sure the numbers I shared in the issue are coherent

Sorry I missed this last week!

This is an interesting case I had not noticed before.... 🤔 Looks like this is to support the ancient ANC workflow Gareth mentioned here. I cannot see any place this is currently used in the code (but after my adventures with the case_id, who knows...).

I guess maybe it is safer to leave it... 🤷

I rebased the branch off master to fix this weird CI issue but I kept a snapshot of the branch rebased off 4.10.x in the branch 9293-freetext-views-4.10
