The fact that the index file has grown so much indicates that it's sucking in a bunch of
extra objects from the .keep pack, and you're seeing the duplication.

I'm not sure how that's happening, though.  I thought the --local flag to git-pack-objects told
it not to do that.

I thought it had to be doing that (hence the increase in object counts
given by the git-gc runs), but wasn't sure if this behaviour was
intentional.

This isn't true if alternates are in use, but this repo is alternate-free.
