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.

# 098 StatusIndicator 状态标记
|
||
|
||
## 用途
|
||
|
||
以图形加文字标出状态：成功、警告、错误、离线、处理中。每种状态有独立形状（对勾圆、三角、叉圆、断开的 Wi-Fi、旋转菱形），并总是显示文字，不只靠颜色。
|
||
|
||
## 最小示例
|
||
|
||
```go
|
||
feedback.StatusIndicator(c, feedback.StatusSuccess, feedback.StatusIndicatorOptions{Label: "API online"})
|
||
feedback.StatusIndicator(c, feedback.StatusOffline, feedback.StatusIndicatorOptions{})
|
||
```
|
||
|
||
签名：`func StatusIndicator(c *ui.Context, status Status, opts StatusIndicatorOptions) ui.Element`
|
||
|
||
## 参数
|
||
|
||
| 字段 | 类型 | 默认值 | 含义 |
|
||
| --- | --- | --- | --- |
|
||
| `status` | `Status` | `StatusSuccess` | `StatusSuccess`、`StatusWarning`、`StatusError`、`StatusOffline`、`StatusBusy`；未知值 panic。 |
|
||
| `Label` | `string` | 内置词（Healthy、Degraded、Failing、Offline、Working） | 替换显示的文字。 |
|
||
|
||
## 状态
|
||
|
||
处理中使用 Spinner，减少动画时静止。整体为 `RoleStatus`，名称为文字。
|
||
|
||
## 事件
|
||
|
||
无。
|
||
|
||
## 键盘操作
|
||
|
||
不可聚焦。
|
||
|
||
## 限制
|
||
|
||
- 无 Badge 式的纯圆点模式；PRD 要求不能只靠颜色。
