Can you add a license to the repo? Legally we couldn't run any code without a license attached to it.

...you can't redistribute code without a license, but surely you can legally run it, can't you?

Like, if I write a blog post and put it on my blog, you're allowed to read it, right?

Heck, if my blog contains some Javascript code I wrote, I would imagine your web browser is allowed to run that code without opening you up to copyright infringement, even if I didn't provide an explicit license.
