🤔 这个变动的性质是？

🔗 相关 Issue

参考 #59162 和 #59175。

💡 需求背景和解决方案

Checkbox.Group 原先通过判断 value 属性是否存在来区分受控与非受控状态。显式传入 value={undefined} 时，defaultValue 无法正常生效，且点击选项后选中状态不会更新。

本次改为使用 useControlledState 管理状态，使 undefined 按非受控模式处理，与 Radio.Group 和 Checkbox 的行为保持一致。同时新增回归测试，覆盖默认值初始化和点击更新选中状态的场景。

📝 更新日志

语言	更新描述
🇺🇸 英文	🐞 Fix Checkbox.Group losing default selections and becoming unresponsive when `value` is `undefined`.
🇨🇳 中文	🐞 修复 Checkbox.Group 在 `value` 为 `undefined` 时丢失默认选中项且无法交互的问题。

📝 Summary

Summary by CodeRabbit

Bug 修复
- 修复复选框组在未提供 value 时的状态管理问题，确保 defaultValue 能正确生效。
- 修复点击复选框后选中状态未正确更新的问题，并确保 onChange 回调返回合并后的选中值。
测试
- 增加对默认值、交互更新及变更回调的覆盖。

Walkthrough

CheckboxGroup 使用 useControlledState 管理受控和非受控值。组件通过 mergedValue 统一计算选中状态、上下文值和切换结果。测试覆盖 value 为 undefined 时的默认值和点击更新行为。

Changes

CheckboxGroup 状态管理

Layer / File(s)	Summary
受控状态与选项切换 `components/checkbox/Group.tsx`	组件使用 `useControlledState` 初始化值，移除同步副作用，并基于 `mergedValue` 计算选项切换结果。
选中状态传播与测试 `components/checkbox/Group.tsx`, `components/checkbox/__tests__/group.test.tsx`	`Checkbox` 和 `GroupContext` 使用 `mergedValue`。新增测试覆盖默认选中值及点击后的 `onChange` 参数。

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to c6ae6

Checkbox groups now correctly treat an undefined value as uncontrolled and have regression coverage for initialization and clicks. Controlled groups may perform an unnecessary render after each selection change, creating a small performance cost but no observed state or display inconsistency.

Suggested reviewers: li-jia-nan, qdyanbing

Poem

小兔整理复选框，
默认值稳稳入场。
受控状态齐步走，
点击更新不慌张。
测试敲响小铃铛，
合并取值更明亮。

Reviewed exact head 3ee281808e3092bee5658f8ec18b350596d394e3.

Both added undefined-value regressions fail with the base f18d0cc32484e1a4d56721978fbc72889c51ae0e implementation: the default selection is cleared before interaction. Restoring the PR implementation passes the complete Checkbox Jest suite: 9 suites, 78 tests and 37 snapshots, including four independent review probes.

The additional probes verify that controlled [] remains authoritative while emitting proposed changes, parent-controlled updates render correctly, releasing control to undefined restores interaction, falsy option values (0, false, '') retain ordering, and child registration filters removed options from onChange. The shared hook's setter does not override a defined controlled prop. ESLint, Biome and diff checks pass for the two changed files. At submission, all 42 applicable remote checks pass (two workflow checks are skipped).

The review validates this scoped state change; it does not assert that calling the internal setter in controlled mode eliminates unnecessary renders.

) Sync ant-design/ant-design#59217. Checkbox.Group already treats an undefined value as uncontrolled in the Vue port; add the upstream test cases to lock the behavior in.
