This iteration was developed and tested on top of mm-stable.
I'm seeing now that Sashiko cannot apply this patch, and I think it expects
it to have been built on top of mm-new.

Reviewers -- would it make sense to rebase this on top of mm-new and
re-send this as a v3, or should I wait for feedback on this cycle
before sending out a new version?

In any case, this could have been avoided if I just developed on top of
mm-new. I'll be mindful to do that in the future.

Thank you everyone,
Joshua
