Because of the way I am handling communication all files exist as serialized->compressed->encrypted blob identified only by it's blake3 hash. Any info about them is handled by Notifications. Those are single packets of data saying what they are and signing permission to access.

The first use case will be simply communicating with myself. My computers will share notifications of what is available and they can decide whether to transfer the files between them right away or wait till wanted. I'll have to look at caching algorithms to fine-tune where things get stored. I can't just sync and deduplicate since devices may have differing storage capabilities and I'll have to pick what level of redundancy I want. It is very much a work in progress.

At least storing everything with its hash will make deduplication easy. I am just hoping I can get away with fewer than 32 bytes. I have to carefully revisit the security implications. Anything I can save on hash size is a performance win. Premature optimization ftw!
