 - 代码审查已修正资料刷新未同步全局头像，以及 Linux.do 重新验证在会话时区变化时未保存验证状态的问题；覆盖取消请求、账户切换、错误响应归属、头像保存后迟到响应，以及 UTC−12/UTC＋14 会话的回归测试通过。
 - [ ] 用户验收：真实页面明暗主题和窄屏，头像全局刷新与失败保留、原密码错误、新邮箱发送及通知失败状态。
 - [ ] 外部联调：真实 SMTP 发送新邮箱验证码/旧邮箱通知，真实 Linux.do 授权回调与不同账号拒绝，实际 PostgreSQL 并发事务。本地测试使用隔离数据与模拟上游，不等同于这些外部联调已完成。
+## 局部重绘默认模型同步
+
+- 已修复：局部重绘弹窗打开时，将默认显示的图片模型同步到实际请求模型；下拉框显示与提交使用同一字段，无需手动重新选择模型。
+- 已修复：局部重绘任务优先使用提交的图片模型，并将 `model` 与 `imageModel` 统一为本次选中的模型。
+- [ ] 上传图片，在全局当前模型与默认图片模型不同的情况下打开局部重绘，直接涂抹、填写修改要求并生成，确认不再出现「所选模型与任务能力不匹配」。
+- [ ] 在弹窗中切换图片模型，以及从已有生成图片打开局部重绘，确认提交模型与显示模型一致。
 
 ## 系统模型「拉取模型」弹窗搜索
