Hi OP, First of all, let me say I'm not questioning your expertise or your good intentions. I'm a great fan of (and following closely) a few standards or proposed standards championed by the W3C, mostly related to RDF, verifiable credentials and digital identity, so a bit different from digital archiving. To be a bit more constructive instead of my comment above, I think if the aim is rediscoverability in 100 to 1000 years, what your current proposal is missing, is semantics. Bits are just bits. Discovering what the bits mean is actually a great deal more difficult than checking if a checksum is still valid. Indeed, this gives bits a certain color. A question that you pose, is 'If I change the name of the file, is it still the same digital file?', but you do not get further into an answer. While a filename might be an arbitrary label, the color of the bits (or the intent of the creator/archiver of the file), in my opinion, might be interested for inclusion.
