I ended up paying $20 for the 'working copy' git iOS app and then setup an iOS shortcut to sync my repository to a private github repo. So everything is manual when I click the button for the shortcut it syncs. On the desktop the git extension does the same thing, but is automatic. Conflict resolution is as detailed and I want. Yeah lots of non-opensource components in that flow, but it works well and is perfectly happy when I am totally offline.
