Hm, diff between .json files' versions in _freeze will show differences between the computed outputs e.g. due to changes in computing environments / code / data / etc.

I will definitely check this feature out and point to it in the revision of the manuscript.

Interesting! I haven't migrated to Quarto yet, so I must admit that I missed this feature so far. If _freeze uses JSON, then it's in fact quite similar to reproducibleR chunks for R Markdown. And, you are absolutely right that I can diff the JSON files to manually inspect similarity/dissimilarity.
