 The changed-file explorer is **docked on the right**. Modified files show Before on the left and After on the right. Added files show only After, using the full text workspace; deleted files show only Before. Rename-only files show one empty pane, with the old and new paths in the explorer; renames with text or final-newline changes retain the split view. Before and historical/remote After snapshots are read-only. Selecting **Working checkout** as After binds eligible regular UTF-8 files to normal editor buffers, reusing already-open dirty buffers and their undo history. Editable After supports native edits, completion, undo/redo, and `:w`. Removed files, rename-only files, binary files, symlinks, and submodules remain read-only. Closing the diff keeps its buffers and unsaved edits.

-When a diff occupies the sole workspace pane, its top bar spans the full editor width. The right-docked changed-file explorer starts below that bar rather than covering the header; closing the dock preserves the full-width bar.
+Diff metadata lives in the text-pane borders instead of a separate info row: split panes show their own Before/After revision labels at the bottom-left; a single visible pane shows the combined `before → after` label there. Each pane shows its read-only/editable state at the top-right, independently of keyboard focus. Before is always read-only; After is editable only for an eligible Working-checkout file. The changed-file explorer and panes start directly below configured chrome, and there is no native-buffer help footer. Loading/error/file notices remain visible when applicable. Narrow borders prioritize state and clip titles without painting over the gutter or source text.

 Text panes use normal buffer interaction regardless of writability: motions and counts, search, Visual/Visual Line selections, multiple carets, yank, remapped bindings, and non-mutating actions work in Before and After. Read-only snapshots reject insert/delete/change/paste, repeat edits, undo/redo, mutating plugin effects, and saves, including saves to another path. Their text retains the revision's final newline. Snapshots use separate virtual LSP document identities and do not appear in ordinary buffer lists or dirty-buffer comparisons. Closing the diff disposes unreferenced snapshots and restores the live or original buffer in its workspace pane; snapshots displayed by other panes or tabs remain read-only until closed. Explicit buffer commands and Markdown/plugin navigation retain their ordinary behavior; native LSP definitions use the routing below.
