Just some minor stuff, as I'm no expert.

I do have one question though, will implicit tracking also be a future goal, where are plain mv/cp in a jj repo gets rewritten to a jj mv/cp?

And a minor note on the title, if it only targets metadata it is fine. But if it also tackles #47 and #3386 then a better title would be "Copy info and Copy tracing Design" or "Copy Info and rename tracking for Jujutsu".

Partial reply; I haven't added anything for merge resolution yet, need to think about it for a while.

@newren Hello Elijah, this may be of interest for you, would you mind taking a look at it?

I renamed the doc and file name to better capture the 'tracking' aspect

I think this looks good enough to start implementing. @fowles has already started working on it. Can we get an approval from a non-Googler? Thanks
