Enter 已送达输入框却没有触发表单默认提交；点击或按键触发导航后，旧页面收尾事件又可能被当作失败。WebDriver 适配还需与原生输入共享焦点、命中和默认激活语义。本 PR 将协议转换留在适配层，将真实输入与默认动作保留在核心输入层。

一图看懂

图示说明问题、修复机制与行为边界；点击可查看原图。验收归属不等于当前提交通过结果，版本和测试证据见下文。

行为与实现

ClassicClickPreparation 用 Dom / Pointer { point, viewport } 表达两条路径，让指针所需数据随状态携带。点击预检核对遮挡与 frame 祖先；Enter、换行、取消默认动作有各自语义。导航后的收尾按旧事件所属生命周期处理，不能吞掉无关输入错误。类型设计依据 Rust API Guidelines：用类型表达参数语义。

代码阅读路线

1. moli-protocol-webdriver-classic/src/commands/elements.rs、actions/types，server 的 classic helpers/state：协议校验、点击准备与类型转换。
2. moli-protocol/src/domains/input.rs、DOM resolve：焦点、命中与事件分派。
3. renderer 的 script_vm/input_dispatch.rs、element activation/default_action、forms/submission：核心默认动作及导航切换后的收尾。
4. classic、keyboard_events、forms/event_activation 与 CDP smoke：从外部行为核对上述边界，而非只验证辅助函数返回值。

Case 与回归契约

负责 274,386,465,731；原第 6 类键盘/导航对应 274、465，第 8 类 Enter 搜索对应 731，386 是额外保留的 1.1.8 失败 case。

覆盖 Enter/换行、焦点、preventDefault、遮挡和跨 frame、Mock/真实布局、导航前后的输入失败。历史两项遮挡点击测试在旧输入 HEAD 失败，依赖布局后保持测试不变通过；精确 CI 红绿对照。这说明布局是点击功能的真实前提，不能以 iframe 特例或跳过断言修复。

历史 fa1c36ef558cde8751883bff174dac7417395220 四题按冻结动作和评分单轮 4/4、零重试；验收说明、逐题结果。任务执行前的启动超时与任务重试需区分，失败启动记录仍保留。

此 PR 当前状态为 CLOSED，最后 head faf55d0966aba39622e99253007733618bc60484，base codex/pr640-reopen-layout；上述历史任务结果不应改标为该 head 的新验收。最终提交检查见 Checks，实现来源 #736。历史堆叠依赖与现在剩余三个 PR 的 main base 不相同。

Reviewer 重点

默认动作是否仍可被事件取消？指针路径是否按真实遮挡/frame 关系判断？导航切换后的合法收尾和真实错误是否正确区分？

整组验收与证据入口

这组修复来自 #640，对应 1.1.9 的 34 个失败 case，加上 1.1.8 已失败的 386，共 35 个唯一 case。按最终职责分配为：#756 布局 27、#757 输入 4、#758 网络 3、#761 文本 1；#755、#759、#760 以各自独立功能契约验收，不重复认领这 35 个 case。

• 逐 case 问题来源与最终归属、最初 11 类分组。595 在最初分类中是零宽链接问题，最终归属网络，但仍有布局前提。
• 七个 PR 的机制图、逐题结果与审查报告。这是历史验收报告；其中旧 HEAD、旧分支依赖及旧设计，须与本详情中的当前实现、版本信息区分。
• 历史逐项验收来源总表。表内结果来自多个分区、版本和合同，不能表述为当前统一二进制的一轮 35/35。历史 67 是传输超时，不认领为本组功能修复。

Sequential Navigation Soak A/B

✅ HEAD completed the 200-navigation resilience and memory observation.

One browser process, one target, and one CDP session navigate CSDN → SegmentFault → Huaban → example.com repeatedly. This run issued 200 Page.navigate commands per binary.

Common ancestor ef06d30495 → HEAD faf55d0966; benchmark order: base-first; workflow: success.
