If software is deduplicating images by SHA including metadata, it's missing a lot about photography workflows :) So, huge props (and I mean that - so many tools get that wrong!) on your approach of trying to identify asset groups and trying to ID members via a number of heuristics. If you want to go deeper, I suggest grouping everything by image content - that means, at the very least, comparing images via a resolution independent hash. (E.g. average down to e.g. an 8x8 picture in greyscale for the simplest approach). (undouble does that nicely, and has a number of different approaches: https://erdogant.github.io/undouble/pages/html/index.html https://erdogant.github.io/undouble/pages/html/index.html)
