T46: Ely peeks over the main window's top edge from behind it, as the owner asked after the 0.1.3 film: her head and fingers from the icon's paths in a transparent window of her own, kept on the edge as each platform allows, macOS's child window, Windows' owned popup, X11's popup moved and stacked above the frame, Wayland's anchored popup; ten faces follow the most pressing of the sessions' marks, with hops, a shake and a rise; a press winks; Settings, Terminal, Ely turns her off

 - `build.rs`: on Windows, the icon into the executable as resource 1, through `assets/icons/elyterminal.rc`. `.cargo/config.toml`: Windows builds carry the C runtime. `rust-toolchain.toml`: the toolchain rustup installs.
 - `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, at the size the settings keep, which it keeps as it settles. `src/menus.rs`: the menu bar, the keys of Quit, the font's size and Minimize, and what they do. `src/blur.rs`: what the window shows of the desktop, from the opacity and blur settings, set as they change; `blur/macos` gives gpui's NSVisualEffectView a material that blurs; `blur/wayland` asks a Wayland compositor for blur behind the window's surface through `ext_background_effect_v1`; `blur/x11` names the window's pane in `_KDE_NET_WM_BLUR_BEHIND_REGION`. `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/workspace/widths.rs`: the side columns' widths, which a drag on their border sets and the settings keep once it rests. `src/workspace/events.rs`: what a session's terminal reports: title, folder, bell, the state its row shows, the program's exit; and a press on a notification a session posted. `src/sessions.rs`: a session and its row, with the mark of its status and what hover shows of it; `sessions/orb` draws the mark, 3 by 3 dots on one clock. `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: Files' marks, and the Git panel's status, stage, unstage, discard, commit and log; `src/git/diff.rs` reads git's diff into Ely's stretches. `src/git/panel.rs`: the Git panel's state and actions; `src/git/panel/view.rs`: how it draws.
+- `src/pet.rs`: Ely, peeking over the main window's top edge from a window of her own while the settings want her; `pet/faces` draws her faces as SVG from the icon's paths, `pet/look` reads her mood from the sessions' marks and the face she makes at each moment of it, and `pet/macos`, `pet/windows` and `pet/x11` keep her window on the main window's edge where the platform does not.
 - `src/settings`: the model, its ranges, and `SettingsStore`, the global that loads, checks and saves `settings.json`; `window` is the settings window, `window/appearance` its Appearance page, `window/terminal` its Terminal page. `tests/fonts.rs` brings its own main: gpui builds its Mac platform only on the main thread.
 - `src/themes`: built-in terminal themes, the chrome palette each maps to, and `apply`, which dresses the app for the system's appearance; `omarchy`, on Linux, wears Omarchy 4's current theme and follows its switches.
 - `src/term`: the terminal engine. `pty` starts a program through alacritty's event loop; `tap` wraps the pty so its reader scans OSC 0, 2, 7, 9, 99, 133, 777 and 7501, the title stack's CSI 22 t and 23 t, full resets, the mouse modes and, on Windows, win32-input-mode (`tap/modes`) before the parser; `titles` keeps the title a session shows, read in the output's order; `marks` reads OSC 133's prompt marks; `status` reads OSC 7501 and keeps a terminal's records; `notify` reads OSC 9, 777 and 99, the notifications and OSC 9;4's progress, and gathers OSC 99's chunks; `reports` is the view's side of what programs report: it keeps OSC 7501's records, maps OSC 9;4, answers OSC 99's query and alive, and posts the system notifications its session posts; `prompts` turns each mark into an OSC 8 link the parser keeps in a prompt's cells, and finds the prompt to jump to; `herdr` follows herdr's focused pane and its agents' states through herdr's socket while herdr's client runs in the session, and tells the view herdr leads, so herdr opens its links: `herdr/unix` finds the client leading the pty's foreground, `herdr/windows` under the session's shell, and asks its named pipe. `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. `zoom` holds the points Bigger and Smaller add to the Size setting, unsaved. `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, the repeat flag and the key code of AppKit's current event, and the key's own character from the layout, as gpui reads key names; it keeps held keys repeating, and hands Command key-ups to the focused view. `win32` sends a key as Windows' own record, win32-input-mode, and finds a key's own character in Windows' layout. `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: Cmd-, opens the settings window, or brings the open one forward, and Cmd-W closes it; off macOS Ctrl-, and Ctrl-Shift-W, as Ghostty's. Categories sit in the first of two columns of Ely's `ColumnShell`, an Ely `SelectableList` as `SettingsLayout` draws its own, and the open one's rows, Ely's `SettingsRow`, in the second; each column scrolls on its own, which `SettingsLayout`, one box for both, cannot. A category joins the list with its rows. Each change goes through `SettingsStore::update`, which checks and saves, and every view reads the global, so it applies at once. A shell saves only when it names a program the running user may run, as the system's `access` answers, ACLs too: empty for the login shell, a file at a full path, or a name found in one of `PATH`'s full folders; a relative folder counts for none, since it would hang on each session's own folder. On Windows a name without an extension means its `.exe`, as `CreateProcess` reads it; a name with one keeps it. A program whose path is not UTF-8 counts for none: a session starts its program by text. A session runs that same full path, so the check and the start agree; else the row says why and the saved one stays, since a bad shell stops the next start. The window takes focus inside when it opens, so its keys find its context. The app quits with its last terminal window: settings alone hold no terminal.
 - 2026-10-14: settings refuse unknown fields; a bad settings file stops the start and is never overwritten.
 - 2026-10-14: Appearance shows every built-in theme as Ely's `RadioCard` in a `SimpleGrid`, each over a small window in the theme's colors. Separate dark theme copies the theme into `dark_theme`, so turning it on changes nothing until a dark card is picked. A theme change re-dresses the chrome at once. Font family comes from Ely's `FontPicker`; size, line height and padding from its `NumberInput`, which saves a number on Enter, on leaving the field and on each step. A font saves, and a settings file starts, only when gpui loads it as the terminal draws it: gpui falls back to another font without a word and loads none without an `m`, so the terminal draws with no font but its own. The cursor preview is a prompt in the terminal's font and theme, its cursor drawn as the terminal draws it, blinking on the terminal's beat. Opacity moves by whole percents, so the saved fraction carries no float noise. A change the store refuses leaves the setting as it was, and the page says why at its top; a number field drops its draft, and the font picker shows the saved family again. The settings window opens at 900 by 640, room for three theme columns.

The engine reads each when it needs it, so a change applies at once to every session; a smaller scrollback drops the history past it.

 - 2026-10-14: the main window lets the desktop through while Background opacity is under 1, blurred or clear as Background blur says, through gpui's `Blurred` (macOS's NSVisualEffectView, Windows' acrylic) or `Transparent`; at 1 it is `Opaque`. The workspace sets it as the settings change. Ely's `ColumnShell::glass`, added to Ely for this, grounds the columns in the palette's glass, which the opacity sets, so the title bar and every column let the desktop through alike; the palette's `bg` stays solid, so a dialog, the Git diff among them, hides what lies under it. The terminal paints no ground over the glass, or the two would stack; a program's own background (OSC 11) paints over it. Ely's own themes pass their palette too, Ely's colors with the glass set. The settings window stays opaque.
 - 2026-10-15: on Wayland the window asks for `ext_background_effect_v1` beside gpui's `org_kde_kwin_blur`. A guest connection on gpui's own display binds it, takes the effect for the window's surface once, and blurs the window's pane: the surface less Ely's resize margin on each free edge of a client-drawn window, worked out each frame and sent only when it changes; it goes and comes back with Blurred and lands at the surface's next commit, which every frame makes. The guest connection reads the display only while the window opens, before gpui's loop runs, and is never dropped: a drop destroys its proxies through the display, which gpui may close first. The log names what the compositor offers, so which way blur goes: `ext_background_effect_v1`, gpui's `org_kde_kwin_blur`, or none, the desktop clear. Its test runs a `wayland-server` compositor on a socket pair.
 - 2026-10-15: on a client-drawn window, so on Linux, Ely's `ResizeBorder` paints its pane solid and shadowed under the content, which kept the desktop from showing at all. `ResizeBorder::glass`, added to Ely for this, leaves the pane to the content while the window is see-through: no ground, nor the shadow gpui draws under the box, which would tint it. So the blur covers the pane alone and the resize margin stays clear. On X11 the window names its pane in `_KDE_NET_WM_BLUR_BEHIND_REGION` (CARDINAL, 32: x, y, width, height in the window's pixels), as Ghostty names its own, and drops the property when Blurred goes; KWin reads it, other compositors pass it by. It goes over a connection of ELYTerminal's own to `$DISPLAY`, which gpui opens too: a property belongs to the window, whoever sets it. gpui's own `org_kde_kwin_blur` on KDE's Wayland still covers the whole surface, margin included, beyond ELYTerminal's reach.

 - 2026-10-17: a session posts system notifications through gpui's, which the owner asked for. At start `set_app_identity` names the app: on Windows that sets the process's AppUserModelID, which the taskbar groups its windows by too, so a pin made before may show apart, and the first notification writes the app's name under `HKCU\Software\Classes\AppUserModelId`, as gpui needs for an app without a package; on macOS gpui posts only from the app bundle, asks for leave at the first, and logs once, under the `gpui_macos` target, that it posts nothing outside one; on Linux it posts over D-Bus through notify-rust. Each terminal view posts its own, in the order its output asks, so OSC 99's answers keep their place before a DA1 sent after them: when its row's mark turns to waiting, done or error, at each turn, as the row's waiting mark is set, the hover's line for the record its body; when a command C started ends, `Command finished`, or `Command exited with N`, so a prompt drawn again, as macOS's bash 3.2 draws one with its D at a resize, posts nothing, and bash 3.2, which sends no C, posts no command's end, as Ghostty's integration, which skips it, posts none; and when a program asks through OSC 9, 777 or 99, its title and body the body, each line shown as text. It posts only while its window is not active or it is not the session shown, which the workspace tells it, one every 3 seconds at most, a later one logged and dropped; the title is the program's title, else the app's name, as the row names the session, which the tap reads in the output's order, so a title set before a notification in the same output names it. The session's own share a tag, so a new one takes the old one's place where the system allows, as an OSC 99 id does; OSC 9, 777 and OSC 99 without an id each take their own; a session keeps its last 64. A press goes to the window whose session posted it: it shows the window and the session, unless OSC 99 said `a=-focus`, and tells a program that asked `a=report`, `OSC 99 ; i=ID ;`; a press whose record went, a twin Linux stacked and pressed before or one past the 64 kept, still shows its session and tells no program. macOS brings the app forward at any press, `a=-focus` or not, and on Wayland gpui asks for the window with a serial the compositor likely refuses, so KWin and Mutter mark it as asking for attention instead. gpui hears of no close on any system, so `c=1` hears `p=close;untracked` once posted, and alive lists the ids posted and not yet pressed, closed or expired. On macOS and Windows a close takes the notification back, and `w` over 0 takes it back once it runs out, its session gone or not, unless a later post holds its tag; gpui on Linux closes and replaces none, so there a close and `w` pass by, logged, a closed one stays alive, and an update posts beside the old one. `o` passes by: each notification posts only while unseen, which is kitty's invisible, so the query answers `a=focus,report:o=invisible:p=title,body,close,?,alive:w=1`, on Linux `a=focus,report:o=invisible:p=title,body,?,alive`, never with the `c` that close events would need. Windows' toasts are silent, as macOS's are; on Linux the notification daemon decides, and reads the body as markup, so its `&`, `<` and `>` go as entities.
 - 2026-10-18: herdr's shortcuts, which a user found dead, as kitty and Ghostty send them. herdr 0.9.5 asks for kitty's disambiguate, events and alternates on macOS and Linux, and takes `cmd+shift+ctrl+[` as `[` with Shift, Ctrl and Super, `CSI 91;14u`, the symbol as its alternate, `CSI 91:123;14u`, as Ghostty sends it; gpui named the key `{` and cleared Shift, so ELYTerminal sent `CSI 123;13u`, which herdr matches only to `cmd+ctrl+{`. Under kitty's flags a key Shift made a symbol of now goes as its own character with Shift, the symbol its alternate; legacy keys keep fixterms' symbol without Shift, as Ghostty's do. On macOS the key's own character comes from `UCKeyTranslate` on the event's key code, in the layout gpui reads: Command's while Command is down or while the plain one types no ASCII; AppKit's `charactersByApplyingModifiers:` ignores the layout for events built in-process. On Windows herdr asks for no kitty flags and reads the console's key records, and ConPTY asks every terminal for win32-input-mode, `CSI ? 9001 h`; so, as Windows Terminal does, each key that types no text goes as `CSI Vk ; Sc ; Uc ; Kd ; Cs ; Rc _`: the virtual key from gpui's name and the layout (`VkKeyScanW`), its scan code, what Windows types for it (`ToUnicode`, a dead key left as it is), down or up, and the modifier keys, locks and enhanced block from `GetKeyState`. kitty's flags go first, as in Windows Terminal; text stays text, so a repeat or a release goes as a record where its press did, a repeat that types after its modifiers came up too, and a release goes so only there; a full reset ends the mode, as Windows Terminal's does. A key that is down is known by its code, AppKit's key code on macOS and the virtual key on Windows, since gpui names a release by the modifiers left down: a release after Shift came up still goes out. Linux has only gpui's name. A console record holds no Windows key, so no Windows terminal passes herdr a `cmd` binding, and a keypad key goes as its main key, since gpui names it so. On Linux gpui keeps neither the key code nor its xkb state, and names a non-ASCII key by its place on a US keyboard, so a key's own character cannot be found: Shift with a symbol and Ctrl, Alt or Super goes as the symbol without Shift, which herdr matches to a binding on the symbol, `ctrl+{`.
 - 2026-10-18: inside herdr, herdr opens its panes' links, as the owner's Cmd-press and Ctrl-press ask. herdr 0.9.5 wraps a long URL at its pane's edge with no wrap flag and writes its panes' OSC 8 links to the terminal without their targets, so ELYTerminal's own finder opened a cut URL or nothing; herdr itself opens the link under a Ctrl-press, whole from its own pane, a wrapped URL or an OSC 8 target, and underlines it while Ctrl is held. So while herdr's client leads the session and tracks the mouse, every link press goes to herdr as the mouse report it is, and on macOS herdr hears Cmd as Ctrl, the wheel aside. herdr's rules come with it, by its design: while it takes the mouse it keeps its panes' OSC 8 targets from the terminal, so that it alone answers Ctrl-press, and it opens only `http` and `https` links; a `file://` link inside herdr stays shut, since the text the terminal sees may be the label of another link. Shift with the press, which takes the mouse back from a program, is the way past herdr its docs name: the terminal then opens what it sees, a `file://` link too. With herdr's mouse capture off, herdr writes its links' targets out and the terminal opens them itself. Elsewhere ELYTerminal opens the link itself, as before.

Her face follows the most pressing of the sessions' marks: a program that waits surprises her, with a mark and two hops; an error worries her, with a shake; a finish cheers her for 4 s, with a hop; work keeps her eyes on the terminal; calm, she blinks and glances, and dozes after 5 minutes; a press winks at you.
