Git internally doesn’t deal in diffs - the conceptual objects are blobs, trees and commits. A tree is like a directory structure of blobs (basically whole files) and commits link trees in a graph. It’s a graph of filesystem like trees basically - not changesets. Very conceptually simple - hence the stupid “git” content tracker. Git has a pack file format that stores deltas but that is just for space saving.
