页面中的元素已经存在，却返回零面积或旧位置，导致可见元素选择和点击无法继续。该修改修复 inline 片段几何与按需布局失效，让几何消费者读取与当前 DOM、样式和布局环境一致的冻结快照。

Reviewer 图解入口

artifact-site：七个 PR 的职责、依赖、原 11 类与 35 题证据。建议审查顺序：734 → 735 → 736 → 737 → 738 → 739 → 740；实际依赖以指南中的有向图为准。

图解与验收证据见站点报告；精确 HEAD 与完整成功、失败记录见下文。

当前 HEAD 62c07ae866e8ce5dbc0c78c23ee2dc493d7fa393 已基于 main@a54ba82a7ac6462429d2f60cd0dbd0d67c589e84 或其直接父 PR 重放；b0f237b09557 的真实任务/专项证据和新提交的补丁等价边界分别核对。当前 HEAD 的对应真实任务已在独立新环境完整单轮 27/27 通过、零重试；归档旧轮结果与本轮严格区分。动作、评分、合同、二进制和产物哈希审计见 artifact-site 报告。

修复机制

保留 native DOM + Stylo 作为状态来源；输入变化在所属模块标记几何失效，几何请求按需重算并发布冻结结果。片段生成保留空白、block-in-inline 和相对定位的正确包含块语义。默认 Mock 模式不升级为持续布局。

机制示意与验收证据见 artifact-site 审查报告；图片仅用于解释机制，不代表本 PR 的验收结果。

对应验收

本分区负责 27 题：29、66、108、156、163、196、314、349、374、389、399、404、415、418、441、448、506、547、576、585、590、620、640、645、658、666、714。

回归覆盖：几何数值、inline 边界、样式收养/撤销、资源变化、多次读取缓存行为及默认 Mock 策略。五个原有测试由“等待绘制才能读取新几何”更新为“首次精确读取刷新、后续干净读取复用”，保留尺寸、文本和复用断言。

历史版本 48d78ac639a3d5e1738342a6876225f9988cefe3 执行原分配的 28 题，结果 27 通过、1 失败（595），零重试。逐题结果与哈希。595 的布局交互已完成、订阅响应为 200，但网络评分缺少 Referer；其最终验收移至依赖布局的网络 PR。595 依赖证据。原 28 题结果保留原样，不能改写为该版本全部通过。

范围与依赖

以工程 PR #734 为直接基线；diff 展示本分区修改。

本 PR 替代 726，基于更新后的 main；旧 PR 保留讨论与 review 历史。原始 #640 也保留作为拆分来源。

整组功能范围为历史 1.1.9 的 34 个失败任务加 1.1.8 已失败的 386，共 35 题：布局 27、输入 4、网络 3、文本 1。历史 67 是传输超时，保留证据但不归因本组功能修复。逐 case 历史及当前归属；历史 11 类分组。历史 main@de109 的 90 题基线 为 55/90，其运行顺序与后续子集不同，结果差异本身不作为独立因果证明。

7 个 PR 的依赖及逐题验收索引、PR 与提交账号核验。

最终布局 27 题原始审计。714 的 14 个动作均执行，投票落库，但在页面脚本初始化前走原生表单提交，未满足冻结评分所要求的 AJAX 路径。失败分层证据。相同延迟脚本场景中，Chromium、旧布局和当前布局均复现；等待该文档 DOMContentLoaded 后均走 AJAX，未观察到过早 DCL。独立对照。原失败不会被改分或覆盖，Moli 不加入任务专属等待。

全局导航等待实验已放弃：完整 27 题只通过 20 题，其中新增 5 秒等待预算引入额外超时。实验完整记录。最终方案使用原测试框架已有的只读就绪前提，保留动作、评分与二进制；布局 v3 完整轮 26/27，547 在全新环境中单独以 v4 合同 1/1 通过。原失败记录均保留，不将其表述成 v4 单轮 27/27。

布局 27 题逐项来源与 547 失败根因。

35 题最终逐项来源总表；布局是 v3 的 26 题加 v4 单独 547，不是单轮 27/27。

Public-site content, timing, and memory are noisy. This single A/B run reports evidence only; site outcome counts explain missing rows without treating them as a deterministic regression.

CPU and memory timelines

These are bounded 40-point views of the same complete process-tree samples used by the HTML report. CPU uses 100% per occupied logical core; memory lines are RSS first and PSS second when complete PSS samples are available.
