> Well, once committed, the corresponding deltas to parent are part of the branch (that is a node of the branch graph). Not sure what you mean by deltas here, but if you are taking about changes, git don’t store changes, each commit references the state (the content) of the whole repository. The diffs are just a representation calculated to you. Like: `git show <commit B>` shows a diff, but actually what happens is that git calculates the difference between all repository’s files as they were (their contents) in commit A vs their contents in commit B. Git does that in a very efficient way, but commit are actually snapshots.
