读取不存在的表单命名属性会反复全量扫描控件；简单缓存最终答案则会在改名、移除、表单归属变化或跨文档收养后过期。本 PR 使用文档实时名称索引筛选候选，再检查当前归属，避免全扫描而保持实时语义。

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。

机制与边界

不缓存可能失效的最终查询答案。读取真实标准属性不应枚举虚拟名称或意外执行 getter；重复名称、枚举和 descriptor 必须保持原有语义。detached/adopted 文档与控件身份仍按实际 DOM 归属处理。

代码阅读路线

• moli-dom/src/native/host/query_index.rs、document.rs：名称索引与更新生命周期。
• renderer 的 element/forms/form_element.rs、forms、template_install/accessors_forms：候选查询、归属过滤及真实/虚拟属性边界。
• detached objects builders 和 element bridge：脱离文档、收养及元素身份。
• script_vm/tests/dom_xhr/forms/named_lookup.rs 与 forms tests：实时语义和避免扫描的正反对照。

验收场景

场景	必须约束的结果
missing / present	返回当前结果，重复 missing 查询不重复全扫描
改名、移除、form 归属改变	下一次读取立即反映新状态
同名与重复控件	不因索引优化改变返回及集合语义
标准属性、getter、in/descriptor/枚举	不意外调用 getter，不把虚拟名称混进真实属性路径
自定义元素升级、detached、adopted	归属与身份保持正确，旧文档索引不返回错误结果

性能测试使用扫描计数正反对照，语义测试独立检查 DOM 行为；不能只断言缓存命中或依赖运行耗时。此 PR 不认领历史 35 题，历史专项证据见 原 PR #739 与报告。

已合入；最后 head 5f9803a1cf3934a662850f77b577a0ec0f74c380，base main，最终提交门禁见 Checks。旧报告中的 #755 直接分支依赖是历史状态，工程前提已进入 main。

Reviewer 重点

索引是否覆盖每种实际名称/归属变化？命中后是否仍验证归属？查询成本下降是否以真实属性、实时查询或跨文档语义回退为代价？

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。

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.

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 6185ba57be → HEAD b81655b485; benchmark order: base-first; workflow: success.
