 - `src/pet.rs`: Ely, peeking over the main window's top edge from a window of her own while the settings want her, or up from its bottom edge where no room lies above it; she draws at every frame the display gives her window; `pet/rig` draws her from the icon's paths in layers of one color, each moved by a matrix of its own, as the films rig her; `pet/look` reads her mood from the sessions' marks and her pose at each moment of it, `look/curves` the timings of her moves; 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.
@@ -112,3 +112,4 @@ ELYTerminal. A terminal on GPUI and Ely components. `PRD.md` says what it does;
 - 2026-10-19: Ely stands inside the main window, her bottom on its pane's bottom edge, as far in from the left, while her box would not fit above it, which the owner asked for after 0.1.4: on a window at the screen's top or full screen her titled macOS panel, which AppKit keeps under the menu bar, stuck between the menu bar and the terminal, and on Windows and X11 she stood off the screen. The rule lives in `pet.rs`: she stands on the top edge while the room above the pane, up to the top of the work area of the main window's display, holds her box, 123.4 points; each platform measures the room and places her: macOS from the main window's `frame` and its `screen`'s `visibleFrame`, which leaves out the menu bar, both in AppKit's points; Windows from the client rect and the work area (`rcWork`) of the monitor `MonitorFromWindow` names, at the main window's scale, since above it or inside it she stands on that monitor; X11 from the pane's place on the root, up to the top of the RandR monitor holding most of it, as Windows and macOS pick a window's display, or of `_NET_WORKAREA`, its first desktop's, where that lies lower: the work area spans every monitor, so on a lower monitor its top is another's. A Wayland client knows no place of its own, so there she stands on the bottom edge while the window is full screen, maximized or tiled at its top, which gpui reports only for a window it draws itself: under server decorations, as Sway's tiling draws them, she stays on top. gpui moves a popup's anchor never, hears a change of state alone as no change of bounds, and gives an unseen popup no frames, so twice a second she checks where the window's size and state put her anchor, counted from the pane as gpui counts it, and opens there again when it moved. Each place logs the edge she moves to. On WSLg, X11 and Weston's Wayland both put her inside a window as tall as the screen or maximized, and over one with room; headless Sway and a two-monitor Xorg did too.
 - 2026-10-19: Ely's window shows nothing but her, which the owner asked for after a user's 0.1.4 drew a hairline along the top of her box on macOS. gpui opens a popup as a titled panel, style mask 0x8081, titled, full-size content and nonactivating, and macOS draws a titled window's frame, there as a light edge over the clear room above her head. As it is glued her panel turns borderless, nonactivating alone, 0x80, and the log names both masks; a mask that does not take fails the glue, which closes her window, as any failed glue now does, where her window stayed open, unplaced, while the log said she did not show. macOS 27.2 draws nothing of that frame, so the line never showed here, the app active or not; there a real click on her borderless panel still winks her, the front app stays in front, and keys typed after it reach the terminal. On Windows her bare popup, and on Linux X11's override-redirect window and Wayland's xdg_popup, draw no frame, border or shadow.
 - 2026-10-19: a drag moves Ely along the edge she stands on, which the owner asked for after 0.1.5. On macOS, Windows and X11 her glue moves her window after the pointer's place on the screen, `NSEvent`'s `mouseLocation`, `GetCursorPos` and `query_pointer`, since her window moves under the pointer, so a place in it would lag; her window keeps the pointer while the button is held, inside it or not, as AppKit, gpui's `SetCapture` and X's implicit grab give it. A Wayland popup cannot move, so there she moves once let go: the settings keep the place, and the twice-a-second check opens her popup there. She moves by whole points inside the pane, and `ely_left` keeps where she stands, 140 by default, where she stood before; a narrower pane holds her at its right end, and the log names where she is let go. Under Xorg's dummy screen xdotool dragged her 200 pixels and her window followed them; under Sway nested in Xorg, whose X input gives its seat a pointer, xdotool's drag reopened her popup 200 points on. Sway's own `seat cursor` commands send no motion while their press is held, and Sway draws no popup opened before its window settled, so a probe there reopens her before it drags.
+- 2026-10-19: Settings › Terminal checks for updates, which the owner asked for after 0.1.5: under Ely, a switch, on by default, checks at start and once a day, and Check now checks at once. The check runs `curl`, as git runs through its command line, so no HTTP or TLS crate joins the build; macOS and Windows 10 ship it, and a missing curl shows as a failed check. It asks Gitea's API for the latest published release, compares its tag's three numbers with the running version, and the row says what it found; a newer one brings Download, which opens the release's page in the browser, since replacing a running, signed app is a job of its own. An automatic check that finds one posts a system notification, at most once a day, whose press opens the page. Checks run off the main thread, one at a time, each start and finding logged; a failure shows its error in the row. Under Xorg's dummy screen the start's check found 0.1.5 the latest, Check now and the switch checked again, and a build named 0.1.4 showed 0.1.5 out with Download, which opened its page.
