Module diff 

Diff-mode subsystem: engine (pure line + word diff), hunk (data types), state::DiffState (session state owned by EditorState::diff while Mode::Diff is active), and layout (the stacked visual-line model shared by renderer and scroll math). See docs/dev/diff-review.md.

Modules

engine

Line-level + inline-word diff over two strings, producing the Hunk sequence consumed by crate::diff::DiffState. Wraps similar::TextDiff::from_lines so nothing else imports similar directly, and adds two things on top:

hunk

Hunk types for the diff subsystem. Line ranges are half-open [start, end); an Insert has an empty old_lines, a Delete an empty new_lines.

layout

Visual-line model and layout cache for the diff view.

state

DiffState — the in-flight review session attached to EditorState::diff while Mode::Diff is active. Owns the pre-change rope, the working new-side buffer, the hunk list, per-hunk decisions, and focus. See docs/dev/diff-review.md.
