| 2 | +/** |
| 3 | + * @ai-context StatusLine.test.tsx —— 状态行的**契约**测试(批 0-D Task 12;规格 §5.1 / §4.1 / §8.6.1)。 |
| 4 | + * |
| 5 | + * Why jsdom:要断言真实 DOM 上的 `role` / 类名 / 两个槽的渲染与缺席。但 jsdom **不加载样式表** |
| 6 | + * (`vitest.config.ts` 的 `css` 为 false)⇒ 样式类契约与用色契约一律**读文本**(范式 C,同 |
| 7 | + * `ConfirmDialog.test.tsx` / `Modal.test.tsx`)。 |
| 8 | + * |
| 9 | + * 本文件钉住四件事: |
| 10 | + * ① 四档 kind 的类映射 + `role` **二值契约**(`error → alert` 立即播报,其余三档 → `status`); |
| 11 | + * ② `detail` / `action` 两个槽的渲染与**缺席**行为(缺席时不得凭空出现按钮或空节点); |
| 12 | + * ③ **危险语义用色**(控制方 2026-09-11 裁决③ · 规格 §4.1「绝不用于按钮」):危险色只作文字色 |
| 13 | + * —— 本原语 CSS 里连底色声明都没有,且**结构上不可能渲染按钮**(不 import `Button`); |
| 14 | + * 与 Task 14 Step 1 第 4 条的批次守卫**同向**(同一判据、同一方向,不另立标准)。 |
| 15 | + * ④ 动效接缝与 reduced-motion:浮现过渡的可动画属性齐备、**无循环动画**(环境层不得抢注意力)、 |
| 16 | + * `.ed-status` 已进 `motion.css` 那条唯一的媒体查询名单。 |
| 17 | + * |
| 18 | + * 副作用:无(只挂 React 树 + 读四个文本文件)。**不用假计时器**:本原语没有计时器、没有 presence |
| 19 | + * 状态机(浮现是纯 CSS transition 的接缝,驱动权在批 6)。 |
| 20 | + * 边界:不用 jest-dom(本仓未装)—— 一律 `getAttribute` / `textContent` / `queryAllByRole`。 |
