Thank you! From what you describe, Flirt should match up with your ideas very precisely. No matter how small a diff is, some issues only become apparent in the context of the whole code base. That's why I believe local-first review is the way to go.

Ooh, great question. TBH I haven't thought about this too hard yet. I guess a comment could be attached to a line in the left or right side of a diff. The other side wouldn't necessarily be stable, depending on the diff algorithm. How to decide which side to attach the comment to... IDK.

I think I'll have to read a little more about the Radicle protocol to understand what a Flirt backend for it would entail. It looks super interesting so far!

Very cool! I skimmed the user guide's sections on patches. It looks like Radicle doesn't have its own concept of code review? That's a good thing, from the perspective of making a Flirt-backend for Radicle. There's no need for an "adapter" between Radicle's and Flirt's concepts of code review.
