T14: git through its command line: status from porcelain v2 with the branch and HEAD's commit, in conflicted, staged, unstaged and untracked sections; stage and unstage by literal paths fed on stdin, a staged rename with its old path, before the first commit too; commit from stdin; the log as Ely's commits; a diff as git writes it, read into Ely's stretches with changed words marked, none for a binary file; Files' marks read the same records; tests on temp repositories

 ## Layout
 
-- `src/main.rs`: start. `src/lib.rs`: the modules, public so tests and examples reach them. `src/app.rs`: fonts, settings, integration, then the main window. `src/workspace.rs`: the window's content, Ely's `ColumnShell` with the sessions, terminal and right columns, their toggles, the right column's Git and Files switch, the title, and the sessions' lifecycle. `src/sessions.rs`: a session and its row. `src/files.rs`: the Files panel, the shown session's folder as Ely's `Tree` with Git's marks. `src/git.rs`: git through its command line.

 - `src/settings`: the model, its ranges, and `SettingsStore`, the global that loads, checks and saves `settings.json`.
 - `src/themes`: built-in terminal themes, the chrome palette each maps to, and `apply`, which dresses the app for the system's appearance.
 - `src/term`: the terminal engine. `pty` starts a program through alacritty's event loop; `tap` wraps the pty so its reader scans OSC 7 and the mouse modes before the parser. `unix` starts the program itself, so a failed `chdir` fails the start; Windows uses alacritty's ConPTY. `shell` writes the integration scripts at start and builds each shell's launch. `frame` reads the grid into styled rows, `boxes` turns box drawing, block elements and powerline arrows into rects and polygons (`boxes/outline` strokes curves and diagonals into polygons), `ink` resolves colors, `paint` draws rows, decorations and the cursor, `view` is the entity: pty events, metrics, blink, resize. `keys` turns key events into bytes, the kitty protocol and, in `keys/legacy`, xterm's encoding, with no gpui types; `input` is the view's key listeners, the bindings that keep Tab and F6 from Ely's focus moves, and its IME handler; `mac` reads the Option side and repeat flag of AppKit's current event, keeps held keys repeating, and hands Command key-ups to the focused view. `mouse` encodes mouse reports, with no gpui types; `links` finds the link at a cell; `pointer` is the view's mouse listeners: selection, reports, wheel, links, copy and paste. `find` is the find box: Ely's `FindWidget`, and Ely's `find_all` over the grid's shown text.

 - 2026-10-14: the title bar is transparent, as Ghostty's: the content runs under it, Ely's column headers drag the window, and the terminal's header shows the program's title. macOS draws its traffic lights at Ely's origin; elsewhere Ely draws the controls, so windows ask for client decorations, which only Linux reads, and Ely's `ResizeBorder` gives the edges. Cmd-B and Cmd-Alt-B (Ctrl-Shift-B and Ctrl-Shift-Alt-B off macOS) toggle the sessions and right columns, kept in the settings.
 - 2026-10-14: session keys are Ghostty's: Cmd-T, Cmd-W, Cmd-1 to Cmd-8, Cmd-9 for the last, Ctrl-Tab and Ctrl-Shift-Tab; off macOS Ctrl-Shift-T, Ctrl-Shift-W and Alt with the digits. A digit past the last session goes on to the program. A new session runs the Shell setting in home or in the shown session's folder, as Start in says. A session whose program ends closes its row; the last row closes the window, and with no window left the app quits. A bell in a hidden session marks its row until it is shown. A hidden terminal hears no mouse release, so hiding it ends its mouse gesture as releases would: the selection drag ends, and the program hears each held button come up. A row's title is the program's, or the app's name while it names none.
 - 2026-10-14: Files shows the shown session's folder in Ely's `Tree`, not `FileTree`, which takes every path up front and drops empty folders. A folder is read off the main thread when it first opens; the root and the open folders are read again whenever the session reports a folder, so at each prompt. Git's marks come from `git status --porcelain=v1 -z -- .`, run with `--no-optional-locks`, so it never holds `index.lock` against the user's own git, and under the user's `status.showUntrackedFiles`, so a home folder kept in git stays quick. An untracked folder marks what it holds. On macOS, whose file systems ignore Unicode forms, a name keeps its form on disk and meets Git's mark in composed form, as git's `core.precomposeunicode` writes it. A label built from a path shows each control character as its picture, `␊` for a newline: gpui shapes no newline, and a file may be named with one. A program without shell integration gets a line in the right column until it reports a folder. A control in a column header keeps its presses: Ely's header zooms the window on any double press.
+- 2026-10-14: git runs in English with `--literal-pathspecs` and without optional locks. Status reads porcelain v2. Paths to stage and unstage go in on stdin, NUL-ended (`--pathspec-from-file`), so any name and any count pass; an empty list is refused, since git would take it as the whole tree. Unstaging is `git reset`, which works before the first commit, and a staged rename unstages with its old path. A diff is git's own, without external tools, a conflict against our side, read into Ely's stretches; a binary file has none, and an untracked folder none either. The log needs a commit at HEAD: git refuses it before the first.
