+### Tagged Release Process
+
+Every version-tag release must follow this sequence. A branch-only push does
+not require release notes.
+
+1. Confirm that the user wants a release tag and identify the exact release
+   commit and the new `package.json` version.
+2. Find the latest stable version tag reachable before the release commit and
+   inspect the complete commit and file diff from that tag to the release
+   commit. For the first tagged release, inspect the relevant repository
+   history instead.
+3. Draft concise, user-facing release notes in both Simplified Chinese and
+   English based only on verified changes in that range. Use the titles
+   `GoodBuddy <version> 更新内容` and
+   `What's New in GoodBuddy <version>`, with corresponding `功能更新` /
+   `Features` and `问题修复` / `Bug Fixes` sections when applicable. The two
+   language versions must describe the same changes. Do not expose
+   internal-only details, credentials, private content, or unverified claims.
+4. Show the exact bilingual release-note draft to the user and wait for
+   explicit approval. If the release commit or either language version changes
+   after approval, inspect the updated tag range and request approval again.
+5. Only after approval, verify that `package.json` and `package-lock.json`
+   contain the same release version, verify the candidate tag does not already
+   point elsewhere, create `v${package.version}` at the exact approved commit,
+   and push the branch and tag according to the synchronized-remote rules.
+6. Keep both approved language versions as the single source for the GitHub
+   Release body and the packaged first-open release-notes modal. The modal
+   displays the release notes matching the current interface language and
+   contains no button linking to a full release page.
+
+Never create or push a release tag, and never push a previously created
+release tag, before the release-note draft has received explicit approval.
+
 - Before a push that updates the `github` remote, ask whether the user wants a
   release tag unless they already specified that choice. A branch-only push
   does not require a version bump or tag. When the user requests a release,

+- 页面首先显示原生解析、文档转换和 OCR 的运行状态，并明确当前可处理格式、回退能力与不可用原因。部分能力未配置时使用“部分可用”状态，不得把原生文本解析一并标记为失败。
+- “使用场景”分别配置聊天附件和知识库导入。普通用户选择“自动解析”“快速文本”“完整索引”等预设；阈值、并发和超时放入默认折叠的高级设置。
+- 本地 OCR 的全平台基线使用同一组 PP-OCRv6 ONNX 模型和 ONNX Runtime WebAssembly，在 Windows、macOS、Linux 的 x64 与 arm64 上保持相同功能。原生 ONNX、WebGPU、DirectML、CoreML 或 CUDA 只能作为可选加速，失败时必须回退到 WASM CPU。
+- OCR 模型管理与语音模型保持一致：应用不内置权重，用户可按需从 ModelScope 下载，也可在联网设备导出 ZIP 并在离线或内网设备直接导入。语音和 OCR 模型的下载、取消、ZIP 导入、ZIP 导出、删除与打开受管目录使用同一交互语义；ZIP 操作不得隐式切换当前模型或保存解析设置。
+- OCR 模型卡片必须持续显示来源、语言、运行时、体积、安装状态和许可。“打开 ModelScope”直接位于卡片右上角，不再使用“模型详情与手动导入”折叠区。窄窗口下仓库操作换行到模型摘要下方，仍须保持可访问名称和键盘操作。

+- 本地模型按受管目录和固定清单加载。ModelScope 下载地址必须固定不可变 revision、字节数和 SHA-256；下载先进入临时目录，全部校验成功后再原子安装。识别时不得从网络或可变分支临时加载模型。
+- 模型 ZIP 使用版本化的 `goodbuddy-model.json` 清单，声明模型类型、内置目录 ID、文件角色、大小与 SHA-256。导出前重新校验已安装文件；导入时限制压缩包大小、条目数、单文件和总展开大小，拒绝路径穿越、重复、未知、缺失或嵌套条目，并以应用内置目录重新校验后原子安装。ZIP 内的自声明信息不能扩大受信任模型集合。
+- PDF 先读取文本层。仅当页面无有效文本、乱码比例过高或用户选择“始终 OCR”时渲染该页并识别；不得因为单页需要 OCR 而丢弃其他页面已经提取的可靠文本。
+- DOCX、XLSX、PPTX 优先保留段落、单元格、公式、备注等原生语义。转换为 PDF 用于补充版面、页码、图表和图片理解，不作为唯一中间格式。
+- DOC、XLS、PPT 等旧格式通过受控转换 Provider 生成新式 Office 文档和 PDF。转换子进程必须禁用宏和网络，限制输入、输出、内存、超时与临时目录，并在关闭或取消时清理。

+- 用户配置并保存远程 OCR 服务即表示选择该处理路径，不再逐场景重复询问。界面仍须明确显示当前服务名称、处理范围和远程属性，API 密钥只保存在主进程加密设置中，未选中远程服务时不得上传文档。
+- 解析结果使用统一文档结构，至少保留文档标题、来源格式、页码或工作表定位、正文块、置信度、处理方式和警告。聊天附件对结果做有界截断，知识库使用完整结果分块和索引。

+# 文档解析与本地 OCR
+
+## 1. 目标
+
+GoodBuddy 需要用同一条可信文档解析链路服务以下场景：
+
+- 聊天附件问答；
+- 知识库导入、同步、分块与来源定位；
+- 后续的合同审阅、表格分析、演示文稿理解和文档转换。
+
+文档解析不是对话模型的附属功能。它是主进程管理的独立基础能力，设置入口为“设置中心 / 文档解析”。
+
+## 2. 当前基线
+
+原生解析器已经支持：
+
+- UTF-8 文本、代码、配置、HTML；
+- 带文本层的 PDF；
+- DOCX 正文；
+- XLSX 工作表 XML 与共享字符串；
+- PPTX 幻灯片文字。
+
+现有局限：
+
+- 纯扫描 PDF 没有文本层时无法提取内容；
+- DOC、XLS、PPT 等旧版二进制 Office 格式不支持；
+- Office 解析主要提取文字，不能完整保留表格、公式、图表和版面；
+- 聊天附件和知识库直接调用底层解析函数，缺少可配置的统一工作流；
+- 没有本地 OCR 模型状态、真实解析测试和按场景策略。
+
+## 3. 产品原则
+
+### 3.1 双通道解析
+
+PDF 不是所有文档唯一的中间格式。解析应同时保留：
+
+1. 原生语义通道：标题、段落、单元格、公式、备注和对象关系；
+2. 渲染视觉通道：页码、版面、图表、图片和 OCR 结果。
+
+两条通道合并为统一文档结构。转换为 PDF 用于补充视觉信息，不得覆盖更可靠的原生语义结果。
+
+### 3.2 场景工作流
+
+| 场景 | 默认预设 | 行为 |
+| --- | --- | --- |
+| 聊天附件 | 自动解析 | 优先快速提取，文本不足时按需 OCR，有界截断后加入当前请求 |
+| 知识库导入 | 完整索引 | 完整解析、按页或工作表定位、按需 OCR、分块与索引 |
+| 扫描文档 | OCR | 页面渲染、文字识别、置信度与定位保留 |
+| 表格分析 | 语义优先 | 单元格和值优先，PDF 或图片补充图表与打印布局 |
+| 高保真审阅 | 视觉增强 | 原生解析、页面渲染、OCR 或视觉理解合并 |
+
+### 3.3 本地优先
+
+- 文本层和本地 OCR 均在设备上处理；
+- 本地处理不因 Ask 或 Execute 模式改变；
+- OCR 来源必须在“本地模型 / 远程服务”之间明确选择；
+- 配置并保存远程服务即表示用户选择该处理路径，不再增加逐场景授权；
+- API 密钥只能保存在主进程加密设置中；
+- 测试文件不得自动进入聊天或知识库。
+
+## 4. 设置设计
+
+设置中心新增“文档解析”分类，结构如下：
+
+1. 分类页头：“测试解析”“保存设置”；
+2. 运行状态：原生解析、文档转换、本地 OCR；
+3. 使用场景：聊天附件、知识库导入；
+4. 文档转换；
+5. OCR 识别；
+6. 高级解析设置；
+
+OCR 模型区沿用语音模型管理模式：
+
+- 应用不内置模型权重；
+- 用户按需从 ModelScope 下载，下载完成后离线使用；
+- 显示来源、语言、运行时、模型体积、安装与校验状态；
+- 联网设备可导出已安装模型 ZIP，离线或内网设备可直接导入；
+- 支持下载进度、取消、删除、ZIP 导入导出、打开模型仓库和受管目录；
+- “打开 ModelScope”直接显示在 OCR 模型卡片右上角，不使用手动导入折叠区；
+- 模型操作即时生效，解析策略仍通过分类页头的“保存设置”提交。
+
+### 4.1 第一阶段字段
+
+- 聊天附件预设：`auto`、`fast-text`、`high-fidelity`；
+- 知识库预设：`complete-index`、`fast-index`、`high-fidelity`；
+- PDF OCR 策略：`auto`、`always`、`disabled`；
+- OCR 来源：第一阶段固定为 `local`，远程服务入口禁用；
+- 本地 OCR 模型：`pp-ocrv6-tiny`、`pp-ocrv6-small`、`pp-ocrv6-medium`；
+- 单文档最大页数；
+- OCR 并发数；
+- 单页超时。
+
+OCR 来源使用互斥选择。本地模型选中后才显示模型下拉列表、按需下载、导入和本地 OCR 参数；远程服务计划接入 MinerU、PaddleOCR-VL 等接口，第一阶段保持可读但禁用。来源选择本身就是用户的明确决策，不再显示额外的“隐私与云端处理”授权区。
+
+## 5. 架构
+
+```text
+聊天附件 ─┐
+          ├─ DocumentParsingService
+知识库导入 ┘     ├─ NativeDocumentParser
+                 ├─ PdfTextQualityEvaluator
+                 ├─ PdfPageRenderer
+                 ├─ LocalOcrProvider
+                 ├─ DocumentConversionProvider
+                 └─ ParsedDocument merger
+```
+
+`DocumentParsingService` 是唯一场景入口：
+
+```ts
+type DocumentParsingPurpose = 'chat-attachment' | 'knowledge-index'
+
+type DocumentParsingService = {
+  parse(
+    name: string,
+    bytes: Buffer,
+    purpose: DocumentParsingPurpose,
+    signal?: AbortSignal
+  ): Promise<ParsedDocument>
+}
+```
+
+聊天上下文管理器与知识库服务依赖该接口，不直接选择 OCR Provider。
+
+## 6. 统一结果
+
+第一阶段兼容现有 `ParsedDocument`，并逐步扩展：
+
+```ts
+type ParsedDocument = {
+  title: string
+  sourceFormat: string
+  content: string
+  sections: Array<{
+    locator: string
+    content: string
+    method?: 'native' | 'ocr' | 'converted' | 'vision'
+    confidence?: number
+  }>
+  warnings?: string[]
+}
+```
+
+定位字段必须对使用者有意义：
+
+- PDF：`第 3 页`；
+- XLSX：`工作表：预算 / A1:F28`；
+- PPTX：`幻灯片 5`；
+- DOCX：标题路径或页码；
+- 文本：`全文`。
+
+## 7. 本地 OCR 基线
+
+### 7.1 模型与运行时
+
+全平台功能基线：
+
+- 模型：PP-OCRv6 ONNX/ORT；
+- 轻量下载档位：Tiny，约 6 MiB，用于低资源设备和六平台离线链路；
+- 推荐下载档位：Small，约 30 MiB，官方支持 50 种语言；
+- 高精度下载档位：Medium，约 132 MiB，官方支持 50 种语言，但识别较慢且需要更多内存；
+- 运行时：ONNX Runtime WebAssembly；
+- 处理环境：隔离 Worker；
+- 加速：WebGPU 或平台原生执行 Provider，仅作为可选层；
+- 回退：任何加速失败后使用 WASM CPU。
+
+需要覆盖的发布矩阵：
+
+- Windows x64、Windows arm64；
+- macOS x64、macOS arm64；
+- Linux x64、Linux arm64。
+
+模型清单必须固定以下信息：
+
+- 上游仓库和不可变 revision；
+- 文件名、字节数和 SHA-256；
+- 模型族、语言、质量和速度；
+- 许可证名称、完整许可证和来源；
+- 检测模型、识别模型、字符字典的匹配关系。
+
+运行时不得从 `main`、`latest` 或其他可变地址加载模型。
+
+### 7.2 下载与安装
+
+Tiny、Small 和 Medium 模型均由 PaddlePaddle 官方 ModelScope 仓库提供。Small 是默认推荐档位；Medium 面向更高识别质量，但具有更高内存占用和延迟。每个档位的检测模型、识别模型与字符字典配置分别使用固定提交，并在应用内记录文件字节数和 SHA-256。
+
+下载流程：
+
+1. 主进程从固定 ModelScope `resolve/<revision>/...` 地址读取文件；
+2. 禁用凭据与缓存，限制重定向次数和单文件大小；
+3. 写入受管目录下的随机临时安装目录；
+4. 边下载边计算 SHA-256，并核对完整字节数；
+5. 三个文件全部通过校验后写入安装清单；
+6. 原子重命名为正式模型目录；
+7. 失败、取消或退出时删除临时文件。
+
+模型只在下载或用户显式打开仓库时访问网络。OCR 推理从受管目录读取已校验文件，不发起网络请求。
+
+### 7.3 离线 ZIP 迁移
+
+语音模型和 OCR 模型使用同一种离线迁移流程：
+
+1. 联网设备完成受信任来源下载和校验；
+2. 在模型卡片选择“导出 ZIP”；
+3. 将 ZIP 通过组织批准的介质传输到离线或内网设备；
+4. 在相同模型的卡片选择“导入 ZIP”；
+5. 主进程按当前应用内置目录重新校验，并在全部通过后原子安装。
+
+ZIP 根目录包含模型文件和 `goodbuddy-model.json`。清单格式为 `goodbuddy-model-archive`，当前版本为 `1`，记录：
+
+- 模型类型：`speech` 或 `document-ocr`；
+- 内置模型 ID 和显示名称；
+- 文件名、角色、原始字节数和 SHA-256；
+- 导出时间。
+
+导出不能直接信任已有安装清单，必须重新读取并校验每个文件。导入不能只信任 ZIP 自声明内容，模型 ID、文件角色、字节数和哈希必须再次与当前应用内置目录完全匹配。导入通过后复用普通本地安装的受控临时目录和原子重命名路径。
+
+归档处理使用有界流式读写，不把大型模型或整个展开结果复制到内存。主进程限制压缩包大小、条目数、清单大小、单文件大小和总展开大小，并拒绝：
+
+- 绝对路径、`..`、目录或嵌套路径；
+- 大小写不敏感的重复条目；
+- 未声明、缺失或角色不匹配的文件；
+- 模型类型或模型 ID 不匹配；
+- 解压后大小或 SHA-256 不匹配；
+- 超过边界的压缩包和压缩炸弹。
+
+取消文件对话框不会改变安装状态。导入和导出也不会切换当前语音/OCR 模型，不会隐式保存文档解析设置。
+
+### 7.4 PDF 流程
+
+1. 使用 PDF.js 读取每页文本层；
+2. 评估有效字符数、乱码率和图片占比；
+3. `auto` 模式只渲染文本不足的页面；
+4. `always` 模式渲染所有页面；
+5. Worker 将页面限制在配置的最大边长内；
+6. OCR 返回文字、坐标和置信度；
+7. 按页合并原生文本与 OCR，不重复可靠文本；
+8. 达到页数、超时、取消或输出限制时停止并返回明确错误。
+
+受密码保护、损坏或超限的 PDF 不得进入 OCR。
+
+## 8. Office 与转换
+
+### 8.1 新格式
+
+- DOCX：正文、标题、表格、批注和图片关系；
+- XLSX：工作表、单元格地址、值、公式、合并关系和图表；
+- PPTX：幻灯片、文字对象、备注、图片和阅读顺序。
+
+Office 内嵌图片 OCR 属于增强流程，不能替代原生结构解析。
+
+### 8.2 旧格式
+
+DOC、XLS、PPT 通过 `DocumentConversionProvider` 转换：
+
+1. 转换为 DOCX、XLSX 或 PPTX，供语义解析；
+2. 转换为 PDF，供页码、版面和视觉解析；
+3. 合并结果并记录转换警告。
+
+本地 LibreOffice Provider 必须：
+
+- 在隔离子进程中运行；
+- 禁用宏和网络；
+- 使用单任务临时目录；
+- 限制输入大小、输出大小、内存和超时；
+- 在成功、失败、取消和退出时清理；
+- 不接受用户提供的任意命令参数。
+
+## 9. 安全边界
+
+- 文件路径解析、读取、大小检查和格式校验在主进程完成；
+- OCR Worker 只接收当前任务所需的有界页面图像和只读模型；
+- 不向 Worker 暴露文件系统、Electron API、凭据或任意网络访问；
+- 文档内容视为不可信数据，不解释其中的提示词为系统指令；
+- 模型和转换程序必须固定版本并校验哈希；
+- OCR 输出受字符数限制，错误不得包含绝对路径或未脱敏文档内容；
+- 取消、超时和应用关闭必须终止待处理页面并释放模型会话。
+
+## 10. 错误与回退
+
+必须区分：
+
+- 不支持的格式；
+- 文档损坏或受密码保护；
+- 文本层为空但 OCR 未启用；
+- OCR 模型不可用；
+- OCR 超时或取消；
+- 文档页数、大小或输出超限；
+- 本地转换服务未配置；
+- 所选远程 OCR 服务不可用或配置不完整。
+
+`auto` 工作流可以从 OCR 回退到可靠的原生文本，但不能把空结果标记为成功。知识库导入失败时保留来源和可重试上下文。
+
+## 11. 实施阶段
+
+### 阶段一
+
+- 新增文档解析设置分类和持久化契约；
+- 建立 `DocumentParsingService`，供聊天和知识库共用；
+- 将无文本 PDF 识别为可触发 OCR 的明确状态；
+- 接入 PP-OCRv6 Tiny、Small、Medium 的 ModelScope 下载、校验、ZIP 离线迁移、删除与 WASM Worker；
+- 实现真实文件测试和六平台验证入口。
+
+### 阶段二
+
+- 增强 DOCX、XLSX、PPTX 语义结构；
+- 实现按页混合文本层与 OCR；
+- 增加版面、表格和阅读顺序。
+
+### 阶段三
+
+- 增加 LibreOffice 和 API 转换 Provider；
+- 支持 DOC、XLS、PPT；
+- 增加 MinerU、PaddleOCR-VL 等远程 OCR 服务连接配置；
+- 增加高保真工作流和解析结果预览。
+
+## 12. 验收
+
+- 同一份扫描 PDF 可从聊天附件和知识库得到一致的逐页文本；
+- 文本型 PDF 在 `auto` 模式下不运行 OCR；
+- 本地 OCR 在六个平台和两种架构上完全离线运行；
+- 模型文件损坏时拒绝加载并显示可恢复错误；
+- 未安装模型时扫描文档提示用户前往“文档解析”下载，文本型文档仍可原生解析；
+- 下载中可显示文件与总进度并允许取消，失败或取消后不留下已安装状态；
+- ModelScope 下载与 ZIP 导入均经过同一大小和 SHA-256 校验；
+- 语音和 OCR 模型可在联网设备导出 ZIP，并在离线设备导入后完成真实推理；
+- 路径穿越、未知条目、错误模型 ID、篡改文件和超限 ZIP 均被拒绝；
+- 超页数、超时、取消和关闭不会留下运行任务；
+- 测试解析不会创建聊天消息或知识库文档；
+- 选择本地模型时没有任何文档上传；
+- 文档中的提示词不会改变系统、模式或工具权限。
