LGTM. I like the way you break into smaller PRs. They are contained and easy to review :).

Why do we use the seq-no and primary term from getResult whereas we use the version from update?

I saw the too and tried to change it but tests fail. IMO it's a bug but I chose not to fix it in this PR / break BWC.

+1 here too, for a long time. I don't want to pollute this PR as it will be big and holds to more places. I can do it as a follow up.
