Enum DiffSignKind 

pub enum DiffSignKind {
    Add,
    Remove,
    Change,
    Conflict,
}

Per-line gutter sign kind. Renderer-facing surface for D.3.d.1 (TUI) and D.3.d.2 (GPUI sprite atlas) integrations — D.3.d.0 lands the data layer only. D.3.e (line tints) composes on top of the same classification.

Add and Remove are emitted for the obvious cases. Change is emitted on both the baseline-deleted lines (covered by the deletion-block virtual rows) and the current-side replaced lines (which sit in the actual document rows). A row carrying a Change sign tells the renderer “this line replaces baseline content” — useful for the tint pass.

Conflict (D.6.f, 2026-05-31) classifies a current-side row that sits inside a three-way merge Conflict hunk — both local and remote mutated the same base region differently. Renders with a distinct glyph (?) and tint (theme.diff_conflict_line_bg). The variant only fires for three-way sessions; two-way compute_two_way doesn’t emit HunkKind::Conflict, so two-way overlays never produce DiffSignKind::Conflict.
