Oct 13, 2026, 10:56 PM@mjd i know, but that's because the reference to the whole file is a frontend/format concern and representing it as a delta or a full file is an implementation detail, which seems like a split that makes sense to me? I only care about the delta when i am cloning, storing, and diffing. two of those i should never have to think about, and the other is good to have as a computed/derived outcome of comparing two full things rather than encoded directly because then i can choose a different diffing algorithm while keeping a single unitary hash tree datastructure (and not, e.g., have the hash of a changeset depend on the diffing algorithm)
