 Changed-file explorer checks cover reuse of the compact directory tree, removed/historical paths, file-to-directory transitions, remapped tree/selection bindings, filter/open/focus transitions, right-dock geometry, and wheel routing without edits to the underlying document.
 Visibility checks preserve browsing and pane state across Ctrl+e, exclude hidden explorers from focus/wheel routing, and verify full-width review. Status checks preserve catalog associations through sorting, compaction, duplicate inputs, and file/directory collisions, and cover colored A/M/D/R markers, selected/unfocused rows, Tree/List filtering, and sanitized rename paths.
+Diff styling checks cover independent snapshot language/shebang/injection detection, accepted/stale snapshot identity, real-parser cache freshness/reuse/release, syntax foreground over changed backgrounds, real empty rows versus missing counterparts, scrolling-stable diagonal hatching, and tab/wide/combining/control-character clipping. TestBackend omits wide-glyph continuation cells; terminal smoke verifies their actual styling.
