Image validation now uses the same crossOrigin policy as the displayed image. Changing that policy also resets the resource status so a successful retry can replace the fallback. Regressions cover recovery, custom-placeholder loading and ignoring a stale validation result. Validation: 84 Jest tests, 1 snapshot, TypeScript, source ESLint and library compile passed. The existing Less mixin deprecation warning remains; native-browser matrix was not rerun.

Summary by CodeRabbit

• 功能改进
  • 图片加载验证现已支持 crossOrigin 配置；更改该配置时，图片状态会相应更新。
  • 预览图片也会应用其 crossOrigin 配置。

Walkthrough

图片有效性校验现在支持可选的 crossOrigin。Image 和 PreviewImage 将该属性传入校验逻辑。测试覆盖跨域属性设置和 crossOrigin 策略切换时的状态行为。

Changes

图片跨域状态校验

Layer / File(s)	Summary
跨域参数与图片有效性校验 src/hooks/useStatus.ts, src/util.ts, tests/useStatus.test.tsx	useStatus 和 isImageValid 新增可选的 crossOrigin 参数。校验在设置图片源前设置该属性；effect 在 src 或 crossOrigin 变化时执行。新增测试覆盖策略切换后的状态行为。
组件参数传递与测试 src/Image.tsx, src/Preview/index.tsx, tests/crossOrigin.test.tsx	Image 和 PreviewImage 将图片的 crossOrigin 传给 useStatus。新增测试检查 crossOrigin="anonymous" 在设置图片源时的值。

ESLint

If the error stems from missing dependencies, add them to the package.json file. For unrecoverable errors (e.g., due to private dependencies), disable the tool in the CodeRabbit configuration.

ESLint install timed out. The project may have too many dependencies for the sandbox.

断言策略切换后的校验参数。

如果 rerender 后仍向 isImageValid 传入 anonymous，这三个测试仍会通过。mock 只按调用顺序返回结果，当前测试没有检查参数。组件测试也只验证首次渲染的 anonymous 值。

请断言第二次调用使用 use-credentials：

建议的测试断言

    rerender({ crossOrigin: 'use-credentials' });
    await act(async () => {});
+   expect(validate).toHaveBeenNthCalledWith(2, 'original.png', 'use-credentials');
    expect(result.current[1].src).toBe('original.png');
