did some evening hacking on my derivation diff utility and experimented with the output format a bit more. It now shows whether an input has been added, removed or updated and if updated whether that's because of a version bump (v) or a hash change without a version bump (h). Haven't pushed the current version to codeberg yet, as I'm still trying out new ideas, learning about more and more #guix internals that simplify what I'm trying to do along the way, and the codebase is a mess because of that! (hope to abandon this hacky learning project utility in favor of a prospective guix store diff command in guix proper one day)
