release: 发布 v0.6.4 环境自适应与 macOS 打包

新增能力：桌面端新增 macOS 打包支持，electron-builder 增加独立 mac 配置块，产出 dmg，按 arm64、x64 分别单独构建、不产出 universal 包；Pandoc 运行时清单新增 darwin/arm64、darwin/x64 两个官方发行项（含独立许可证文件来源），桌面 Pandoc 候选路径与 prepare-pandoc-runtime.mjs 均已泛化为按 --platform/--arch 参数选取目标，不再只认 Windows x64。AGENTS.md 不再硬编码 Windows 绝对路径与强制 PowerShell 语法，改为按当前 Shell 与仓库实际位置自适应。问题修复：修复解压内置 Pandoc 时未保留 Unix 可执行权限位的问题（unzipSync 不保留压缩包内权限，已补 chmod 0o755）；修复根 package.json 中 build:web-runtime/dev/desktop:dev 三个脚本的构建顺序错误（@md-to-pdf/application 被排在其依赖的 @md-to-pdf/preview-engine 之前，在没有历史 dist 残留的全新环境中会导致类型解析失败）；修正 packages/docx-engine/tests/pandoc-runtime.test.ts 与 apps/desktop/tests/markdown-file.test.ts 中依赖宿主 OS 或路径分隔符的测试断言，避免这些用例只能在特定平台上通过。验证结果：docx-engine 包 93 项测试、desktop 包 62 项测试（61 通过 + 1 项 Windows 专属用例按预期跳过）均通过；全项目类型检查、生产构建通过， git diff --check 无空白错误。跳过依赖 Git 忽略的真实客户文档语料（tmp/）的 test:docx-real-world-corpus 与 test:docx-release-gate-suites 后，其余全部工作区测试均通过；这两步需要接入真实语料的机器上单独执行。本机 macOS （Apple Silicon）实测 npm run package:mac:arm64 全链路成功，内置 Pandoc 3.9.0.2 完成下载、哈希校验与真实 DOCX 冒烟转换；实际截图确认窗口、macOS 原生菜单栏、编辑器工具栏、中文字体与实时预览渲染正常。兼容与部署：版本统一为 0.6.4。本版本仅完成开发基础设施与验证，未构建正式发行文件：没有产出真实签名的 dmg、没有重新构建 Windows 安装包，也没有重新构建 Docker 镜像；正式 macOS 发行产物与 Windows/Docker 同步验证留待 DOCX 发布门禁阶段完成后一并发布。 Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01K5N6pcbjV4jVfXrcH3NcLP

+新会话、上下文压缩后或对当前目录不确定时，在执行其他 Shell 命令前先确认仓库根目录。不得假设固定绝对路径或盘符——协作环境可能是 Windows、macOS 或 Linux，克隆位置因机器而异。可用如下只读方式确认（按当前 Shell 语法改写等价命令）：
 ```powershell
 Get-Location
 ```
 确认目录为：
 ```text
-C:\Projects\md-to-pdf
+git rev-parse --show-toplevel

 随后依次执行只读检查：
-```powershell

 git status --short
 git log --oneline -5
-Get-Content -LiteralPath 'docs\PROGRESS.md' -Encoding UTF8
+读取 docs/PROGRESS.md（显式使用 UTF-8 编码）
 ```
 当前工作区可能包含用户或上一个会话留下的未提交修改。禁止使用 `git reset --hard`、`git checkout --`、`git clean` 等方式丢弃修改，除非用户明确要求。
 ## 3. Shell 与文件操作
- 当前默认 Shell 为 PowerShell，使用 PowerShell 语法。
+- 不假设固定 Shell 类型（PowerShell、bash、zsh 等均可能）；命令语法跟随当前会话实际使用的 Shell，禁止把某一种 Shell 的专属语法当作硬性要求写入产物、脚本或文档。
 - 不要通过绝对路径 `cd` 前缀拼接命令；工具支持时优先使用 `workdir`。
 - 子目录操作使用相对路径或直接设置 `workdir`。
- PowerShell 读取、写入、追加或替换文本时显式指定 UTF-8 编码。
+- 读取、写入、追加或替换文本文件时显式指定 UTF-8 编码。
 - 本地文件修改优先使用补丁工具，避免使用不透明的大段覆盖命令。
 - 不执行破坏性删除；如确需删除，先确认精确目标并向用户说明。

 # 变更日志
 本文档记录 MorphDoc（原 Markdown PDF 导出器）的重要版本变更。
 格式参考 [Keep a Changelog](https://keepachangelog.com/zh-CN/1.1.0/)，版本号遵循
 [Semantic Versioning](https://semver.org/lang/zh-CN/)。发布时以对应版本章节作为
 Gitea Release 页面正文的基础；构建产物、校验和及详细验收记录可继续写入
 `docs/releases/v<version>.md`。
 ## [Unreleased]
 ### 变更
 - 暂无。
 ## [0.6.4] - 2026-08-26
 ### 新增
 - 桌面端新增 macOS 打包能力：`electron-builder` 增加独立 `mac` 配置块，产出
  `dmg`，按 arm64、x64 分别单独构建，不产出 universal 包（内置完整
  Chromium/Electron 与固定版本 Pandoc，合并双架构会让单包体积翻倍）。
 - Pandoc 运行时清单新增 `darwin/arm64`、`darwin/x64` 两个官方发行项及独立
  许可证文件来源（macOS 官方 zip 本身不随附许可证文本）；桌面 Pandoc 候选
  路径与 `prepare-pandoc-runtime.mjs` 均已泛化为按 `--platform`/`--arch`
  参数选取目标，不再只认 Windows x64。
 ### 修复
 - 修复 `apps/desktop/scripts/prepare-pandoc-runtime.mjs` 解压内置 Pandoc 时
  未保留 Unix 可执行权限位的问题（`unzipSync` 不保留压缩包内的权限信息），
  macOS/Linux 上解压出的二进制此前无法直接执行。
 - 修复根 `package.json` 中 `build:web-runtime`、`dev`、`desktop:dev` 三个
  脚本的构建顺序错误：`@md-to-pdf/application` 依赖
  `@md-to-pdf/preview-engine`，但被排在其构建之前，在没有历史 `dist/`
  残留的全新环境（如全新克隆 + 全新 `npm install`）中会导致类型解析失败。
 - 修正 `AGENTS.md` 中硬编码的 Windows 绝对路径与强制 PowerShell 语法，改为
  按当前 Shell 与仓库实际位置自适应。
 - 修正测试用例 `packages/docx-engine/tests/pandoc-runtime.test.ts` 中硬编码
  反斜杠路径分隔符的断言，避免该测试仅能在 Windows 宿主上通过。
 ### 验证
 - `docx-engine` 包 15 个测试文件、93 项测试通过；类型检查通过。
 - 本机 macOS（Apple Silicon）实测：`npm run package:mac:arm64` 全链路成功，
  内置 darwin-arm64 版 Pandoc 3.9.0.2 完成下载、哈希校验与真实 DOCX 冒烟
  转换；未打包应用（`--dir`）可正常启动，主进程/渲染进程/GPU 进程/网络
  服务进程均稳定运行，AppleScript 可正常触发退出。实际截图确认窗口、
  macOS 原生菜单栏、Markdown 编辑器工具栏、中文字体与实时预览（标题、
  任务列表、表格、行内公式、引用块）均渲染正常。
 - 补跑跳过真实语料依赖的全部工作区测试与全项目类型检查、生产构建均
  通过；`test:docx-real-world-corpus` 与 `test:docx-release-gate-suites`
  依赖 Git 忽略的真实客户文档语料（`tmp/`），本机没有该目录，这两步
  在当前环境下无法验证，留待接入真实语料的机器上执行。
 ### 兼容与部署
 - 本版本仅完成开发基础设施与验证，未构建正式发行文件：没有产出真实签名
  的 dmg、没有重新构建 Windows 安装包，也没有重新构建 Docker 镜像；正式
  macOS 发行产物、Windows/Docker 同步验证留待后续门禁阶段完成后一并发布。
 ## [0.6.2] - 2026-08-26
 ### 修复
 - 修复真实长文档中表格分页后的列宽、偏移和行样式丢失，冻结逻辑表格列轨并将

 - 修复 Markdown 表格中 `<br>` 变体、连续换行、实体和行内代码的 DOCX 翻译，
  避免换行逃逸到目标单元格段落之外。
 - 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。
 - 改进 PDF 文本流排序和数值范围归一化，减少窄字符重叠、跨视觉行破折号及重复

 ### 验证
 - 合成基线与长庆真实文档两套严格门禁为 `280/280`，M4N 复杂表格文档为
  `140/140`。
 - 健康数据长文档残余误报为 `6/115`（`5.22%`），均核查为重复表头自动对齐或
  取样错配，基础设施错误为 0。
 - 全项目测试、类型检查、生产构建、正式 Docker、内置字体 NSIS/ZIP 和离线发行
  归集通过。
 ### 发行与兼容性

 # 墨呈进度
-最后更新：2026-08-04
+最后更新：2026-08-26
 ## v0.6.4 环境自适应与 macOS 打包
 - `AGENTS.md` 不再硬编码 Windows 绝对路径与强制 PowerShell 语法；会话启动检查改为
  动态确认仓库根目录，命令语法跟随当前会话实际 Shell。
 - 新增 macOS 桌面打包能力：`electron-builder` 增加独立 `mac` 配置块，产出 `dmg`，
  按 arm64、x64 分别单独构建、不产出 universal 包；Pandoc 运行时清单新增
  `darwin/arm64`、`darwin/x64` 两个官方发行项（含独立许可证文件来源，因为 macOS
  官方 zip 本身不随附许可证文本），`prepare-pandoc-runtime.mjs` 与桌面 Pandoc
  候选路径均已泛化为按 `--platform`/`--arch` 参数选取目标。
 - 顺手发现并修复两个此前从未在 macOS 全新环境下暴露过的真实 bug：
  解压内置 Pandoc 时未保留 Unix 可执行权限位（`unzipSync` 不保留压缩包内权限，
  已补 `chmod 0o755`）；根 `package.json` 的 `build:web-runtime`/`dev`/`desktop:dev`
  把 `@md-to-pdf/application` 排在其依赖的 `@md-to-pdf/preview-engine` 之前构建，
  在没有历史 `dist/` 残留的全新环境中会导致类型解析失败，已调整构建顺序。
 - 本机 macOS（Apple Silicon）实测：`npm run package:mac:arm64` 全链路成功，内置
  darwin-arm64 版 Pandoc 3.9.0.2 完成下载、哈希校验与真实 DOCX 冒烟转换；未打包
  应用（`--dir`）可正常启动，主/渲染/GPU/网络服务进程均稳定运行，可正常退出。
  实际截图确认窗口、macOS 原生菜单栏、编辑器工具栏、中文字体与实时预览（标题、
  任务列表、表格、行内公式、引用块）均渲染正常。
 - 跳过依赖真实语料的 `test:docx-real-world-corpus`、`test:docx-release-gate-suites`
  后，其余全部工作区测试、全项目类型检查和生产构建均通过；这两步依赖 Git 忽略、
  需从可信来源单独提供的真实客户文档（`tmp/`），本机没有该目录，留待接入真实
  语料的机器上执行。
 - 本版本仅完成开发基础设施与验证，未构建正式发行文件：没有产出真实签名的
  dmg、没有重新构建 Windows 安装包，也没有重新构建 Docker 镜像；下一步是统一
  DOCX 发布门禁的产出目录规范（版本号动态化，不再写死）并新增清理脚本，随后
  评估四套 140 门禁矩阵的并行执行策略。
 ## 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。

 - 发布门禁已由一次性 560 拆分为四套独立 140：标准合成基线优先，随后

 # 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。

SkyJourneyandClaude Sonnet 5	c4df499680	release: 发布 v0.6.4 环境自适应与 macOS 打包新增能力：桌面端新增 macOS 打包支持，electron-builder 增加独立 mac 配置块，产出 dmg，按 arm64、x64 分别单独构建、不产出 universal 包；Pandoc 运行时清单新增 darwin/arm64、darwin/x64 两个官方发行项（含独立许可证文件来源），桌面 Pandoc 候选路径与 prepare-pandoc-runtime.mjs 均已泛化为按 --platform/--arch 参数选取目标，不再只认 Windows x64。AGENTS.md 不再硬编码 Windows 绝对路径与强制 PowerShell 语法，改为按当前 Shell 与仓库实际位置自适应。问题修复：修复解压内置 Pandoc 时未保留 Unix 可执行权限位的问题（unzipSync 不保留压缩包内权限，已补 chmod 0o755）；修复根 package.json 中 build:web-runtime/dev/desktop:dev 三个脚本的构建顺序错误（@md-to-pdf/application 被排在其依赖的 @md-to-pdf/preview-engine 之前，在没有历史 dist 残留的全新环境中会导致类型解析失败）；修正 packages/docx-engine/tests/pandoc-runtime.test.ts 与 apps/desktop/tests/markdown-file.test.ts 中依赖宿主 OS 或路径分隔符的测试断言，避免这些用例只能在特定平台上通过。验证结果：docx-engine 包 93 项测试、desktop 包 62 项测试（61 通过 + 1 项 Windows 专属用例按预期跳过）均通过；全项目类型检查、生产构建通过， git diff --check 无空白错误。跳过依赖 Git 忽略的真实客户文档语料（tmp/）的 test:docx-real-world-corpus 与 test:docx-release-gate-suites 后，其余全部工作区测试均通过；这两步需要接入真实语料的机器上单独执行。本机 macOS （Apple Silicon）实测 npm run package:mac:arm64 全链路成功，内置 Pandoc 3.9.0.2 完成下载、哈希校验与真实 DOCX 冒烟转换；实际截图确认窗口、macOS 原生菜单栏、编辑器工具栏、中文字体与实时预览渲染正常。兼容与部署：版本统一为 0.6.4。本版本仅完成开发基础设施与验证，未构建正式发行文件：没有产出真实签名的 dmg、没有重新构建 Windows 安装包，也没有重新构建 Docker 镜像；正式 macOS 发行产物与 Windows/Docker 同步验证留待 DOCX 发布门禁阶段完成后一并发布。 Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01K5N6pcbjV4jVfXrcH3NcLP	2026-08-26 19:32:38 +08:00

SkyJourney	64445322eb	release: 发布 v0.6.2 DOCX 真实文档修复新增能力：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。	2026-08-26 10:50:20 +08:00
