 ## Stack
 
 - Rust 1.95, edition 2024. One crate: `ely-gpui-component`.
-- gpui and gpui_platform from Zed's repo by git at 1a28cff, the code gpui-pre 0.3.7 republishes. gpui takes `stacker`, which keeps deep layouts off the stack's end; gpui_platform takes `font-kit`, without which macOS draws no text. Feature `runtime_shaders`, on by default, turns on gpui_platform's: machines without Xcode lack the Metal compiler.
+- gpui, gpui_platform and gpui_web from crates.io's `gpui-pre` snapshots at `=0.3.8`, Zed at 279fe07, the pin GPUI Kit 0.7.1 holds; each keeps its crate name through `package`. gpui takes `stacker`, which keeps deep layouts off the stack's end; gpui_platform takes `font-kit`, without which macOS draws no text. Feature `runtime_shaders`, on by default, turns on gpui_platform's: machines without Xcode lack the Metal compiler.
 - Assets, embedded with `rust-embed`: Lucide 1.48.0 icons (ISC), Inter 4.1 (regular, medium, semibold, italic), JetBrains Mono 2.304 and IBM Plex Sans Regular (OFL). Plex sits unmodified, its name reserved, where gpui's svg renderer loads it: gpui_web answers `.SystemUIFont` with it, and svg text falls back to it on the web.
 - Catalog data: `emojis` (Unicode emoji), `isolang` (ISO 639, native names), `isocountry` (ISO 3166), `iso_currency` (ISO 4217, also minor units for money).
 - Codes: `qrcode` (QR) and `barcoders` (Code 128, EAN-13), both MIT OR Apache-2.0, default features off. `rqrr` 0.11 ((MIT OR Apache-2.0) AND ISC, default features off) reads QR codes from the host's frames.

 - `TextInput::bounds_for` reads the last layout. Text changed this frame clamps to the laid-out end until the next paint.
 - The harness types with `dispatch_keystroke` through `AnyWindowHandle`, which leaves the root view free to redraw.
 - The macOS open panel runs out of process too. Escape does not reach it; the harness sends it `cancel:`.
-- gpui's `test-support` stays behind this crate's `test-support` feature and is never on for the gallery: it tracks every entity handle for leaks and records every `debug_selector`'s bounds each frame.
+- gpui's `test-support` and `leak-detection` stay behind this crate's `test-support` feature and are never on for the gallery: one records every `debug_selector`'s bounds each frame, the other tracks every entity handle, so a test that leaks one fails (`tests::a_leaked_entity_fails_its_test`).
 - A tracked `FocusHandle` is a Tab stop only when built with `.tab_stop(true)`. `tab_index` on the div reaches only handles gpui makes itself. `primitives::tab_stop` keeps one per id.
 - Floating lists go below their anchor, or above when only above has room (`forms::options::float`). gpui's own switch keeps the anchor point, so a flipped list would cover its trigger. An option list is at least its trigger's width and at most the window's less `window_margin` each side, so gpui can snap it inside and its rows end in an ellipsis; wider, gpui pins it left and the rest runs off.
 - A trigger that opens a list goes through `forms::select::listing`: toggle, keys, blur and popup live there, for Select, TabOverflowMenu and Breadcrumb alike. A field that suggests as you type floats its rows through `forms::select::Picker` and `forms::options::Popup`, as Combobox and TagInput do.

 - 2026-10-05: `TemplatePicker`'s list is one Tab stop: up, down, Home and End move the highlight, Enter uses it; rows are list items with name, selection, place and count; its search placeholder, All chip, Use button and empty line read from the builtin catalog in English and Chinese. Before, the rows were reachable by mouse alone and anonymous in the AX tree.
 - 2026-10-05: `SelectableList` is a list in the AX tree, named by `label`; each `ListItem` is a list item with its title as name, its description, its selection, and, in a selectable list, its place and count (`ListItem::place`). Before, the rows had no role and were missing from the AX tree.
 - 2026-10-05: `NumberInput::blank` shows a placeholder, not a number, as for a mixed selection; Enter or blur on the empty field commits nothing, a typed number commits as usual. Before, a mixed field held a real number the owner had to invent, and Enter sent it. `ScrubInput` moved to `number/scrub.rs`.
+- 2026-10-07: gpui comes from crates.io's `gpui-pre` at the exact snapshot GPUI Kit pins, not from Zed's git. Two sources build two gpui crates whose types do not mix, so Ely and Kit could not share a window. The code is still Zed's; the publisher is not. This replaces the 2026-09-28 choice of Zed's git, and the pin moves when Kit's does.
