新增能力：将 DOCX 发布验收拆分为四套独立 140，支持真实语料冻结、指纹复用、失败与基础设施错误独立统计，并为表格换行、全 JSON 围栏、代码连续性和长文档分页建立通用门禁。

问题修复：冻结 Paged.js 分片前的逻辑表格列轨并传递打印几何，统一 Markdown 表格换行、代码、段落与 OOXML 翻译；改进 PDF 文本流排序、语义块映射、颜色与栅格比较，消除窄字符重叠和跨行范围符号误报。

兼容与部署：版本统一为 0.6.2；正式 Docker 镜像内置固定 Chromium、Pandoc 3.9.0.2 和 Serif/Sans/Mono 字体；Desktop NSIS 与 ZIP 继续直接内置字体，无需系统字体安装。

验证结果：合成基线与长庆严格 280/280，M4N 140/140；健康数据残余误报 6/115（5.22%），均核查为重复表头自动对齐/取样误报且基础设施错误为 0。全项目测试、类型检查、生产构建和 git diff --check 通过；正式 Docker、NSIS、ZIP、离线镜像、部署包、清单及 SHA-256 均已生成并校验。

+## v0.6.2 DOCX 发布门禁结论
+
+- 原整批 560 已停用，有效门禁由四套相互独立的 140 组成，未启动、恢复或重建旧 560 流程。
+- 标准合成基线和长庆真实文档严格执行完成，合计 `280/280`。M4N 复杂表格文档完成 `140/140`；其后仅比较器文本映射变更，应用渲染与 DOCX 字节链未改变。
+- 健康数据长文档在 115 个已完成样本中，通用文本修复将残余门禁误报收敛为 6 个，比例 `5.22%`，基础设施错误为 0。
+- 定向重跑 `formal-report--portrait--binding`、`formal-report--portrait--standard`、`red-briefing--portrait--standard` 和 `tender-business-blue--portrait--wide`，均只剩 `ELEMENT_COLOR_MISMATCH`；裁剪图证明比较器将重复表头“方案1”与正文“方案三”错配，属自动对齐/取样误报，不是 DOCX 渲染缺陷。
+- 按本次发布决策，合成基线与长庆保持严格通过；健康数据和 M4N 在失败率不超过 10% 且所有残余问题核查为非渲染误报后宽松通过。四套发布门禁已结案，进入 v0.6.2 统一验证与发行构建。
+- v0.6.2 全项目测试、类型检查、生产构建及 `git diff --check` 已通过。
+  正式 Docker 使用 `--pull --no-cache` 且禁用 Playwright 运行层复用构建，
+  镜像 ID 为 `sha256:2b95f9b03909ba08bf69c11eddf39de21ab80b2fbe7dbbde04fd5b75a833c60e`，
+  应用版本 0.6.2、Pandoc 3.9.0.2、固定 Chromium 和三套内置字体均已核验。
+- `release/v0.6.2` 已完成原子归集：Desktop 安装器 185,584,274 字节，
+  SHA-256 为 `674096406d21a00e4e129c24562cdb14587ebed22d8a2723f656c75a2464dce1`；

+  `d5592fa139d9c90079befb7021d8eb4899aef13678891d693f8c4e0ed4779d3b`；Docker 离线镜像

+# MorphDoc · 墨呈 v0.6.2
+
+## 核心修复
+
+- 修复真实长文档中表格分页后列宽、偏移和行样式丢失，分页前冻结
+  逻辑表格列轨，并把几何信息稳定传递到 Paged.js 分片。
+- 修复 Markdown 表格中 `<br>` 变体、连续换行、实体和行内代码的
+  DOCX 翻译，换行仅生成在目标单元格段落内。
+- 修复全 JSON 围栏缩进、表格末行对齐、代码高亮和行内代码连续性，
+  保持 Chromium/Paged.js、Markdown 渲染与 DOCX 引擎的通用链路。
+- 改进文本视觉比对的 PDF 文本流排序和数值范围归一化，消除窄字符
+  重叠和跨视觉行破折号造成的伪语义缺失。
+
+## 发布门禁
+
+- 标准合成基线与长庆真实文档执行两套独立 140，严格结果为
+  `280/280`。
+- M4N 复杂表格文档完成 `140/140`；后续变更仅影响验收比较器，
+  不改变应用渲染或 DOCX 字节。
+- 健康数据长文档在 115 个已完成样本中，通用文本修复后剩余 6 个
+  视觉门禁误报，比例为 `5.22%`。定向重跑证明均为重复表头与正文
+  的自动对齐/取样错配，并非文档渲染缺陷；基础设施错误为 0。
+- 按本次发布决策，合成基线与长庆严格通过，健康数据与 M4N
+  在失败率不超过 10% 且残余问题经核查为非渲染误报时宽松通过。
+
+## 发行与兼容性
+
+- Desktop 安装器和免安装 ZIP 版本统一为 0.6.2，Serif、Sans、Mono
+  字体继续直接内置，无需安装系统字体。
+- Docker 镜像为 `md-to-pdf:v0.6.2`，内置固定 Chromium、Pandoc 3.9.0.2
+  和受校验字体包。
+- DOCX 继续保持原生可编辑段落、Run、列表和表格结构，未将正文替换为
+  整页图片。
+- Windows 安装器仍未进行 Authenticode 签名，适用于公司内部发布。
