MyGo v0.5.5 returns ui.Element as a checked value handle instead of a
pointer. Migrated with `mygo migrate-ui`, then fixed what the codemod
leaves to review:
- Element nil checks become .Valid(); absent elements are ui.Element{}.
- Input handlers and paint callbacks run outside the build pass, where
elements expire and Context methods are inert: read IsDisabled into a
local during the build, keep a ui.Handle for Focus, use c.Services()
for clipboard access, create ui.Local state during the build.
- Add core.AutoFocus: v0.5.5 records an overlay's opener after its
content builds, so same-frame autofocus lost focus restore on close.
It focuses one frame later; cascader rows defer their focus likewise.
- core.OverlayLayer identifies build passes by the root element, not
c.Now(), which repeats across passes and under the Tester clock.
- Context menus survive the opening press counted as PressedOutside;
split button tooltip no longer reorders its open menu; disabled
menubar rows pass presses to the panel; Form defers blur-started
async checks so the growing message no longer moves Submit away
from the release; Combobox drops its disabled copy now that MyGo
blocks typing under a disabled wrapper (canary flipped to a guard).
- The Tester clock is virtual: tests use Advance/Now instead of
time.Sleep/time.Now and read element state inside the view. The web
mirror advances the clock to wall time before each frame and input.
- AGENTS.md and docs describe the value Element API and the new pin.
Snapshot goldens are darwin-only and were not re-verified here.

| 运行时依赖 | macOS：系统框架。Windows：无需 WebView2。Linux：GTK 3（MyGo 通过 GtkGLArea 绘制） |
已实测环境
| 系统 | 架构 | 会话 | 结果 |
|---|---|---|---|
| macOS（Darwin 27.2） | arm64 | Aqua | 无窗口测试、快照、Gallery 构建 |
以下项目尚未实测，不宣称支持：Windows（x64、arm64）、Linux X11、原生 Wayland、XWayland；VoiceOver、Narrator、NVDA、Orca；跨缩放显示器移动窗口；100% 以外的真机显示缩放。无窗口测试已覆盖 1x 与 2x 渲染，不替代真机。
快照基准
快照按系统分目录：testdata/snapshots/<GOOS>/。目前只有 darwin 基准。其他平台须在该平台运行 go test -update . 生成并人工检查后提交；在此之前用 go test -skip Snapshot ./... 运行其余测试。
离线
库与 Gallery 不发起网络请求，无遥测、账号或远程字体。图标与角饰随代码嵌入。浏览器镜像按 -web 传入的地址监听：127.0.0.1:8080 仅本机可达，:8080 对所有网络接口开放。
