Diff System
Diff extraction — design fragment (`lattice-host::diff` → the `lattice-diff` crate)
Intra-line diff refinement
N-way Diff Membership (D.8)
Magit — Git porcelain as a core plugin
magit-blame — annotations on the file, not a buffer full of text
magit-hunk-mode — the mode that owns diff *content*
Hunk-level staging
Magit project diff (the editable cross-file diff view)
Magit repo scoping — the repository is the active buffer's, not the shell's

Git & diffs

Combines vim's modal editing power with emacs's extensibility model on a non-blocking, multi-threaded core.
