+# GoodBuddy 开发与构建
+
+## 环境要求
+
+- Node.js 24，或当前锁定依赖明确支持的 Node.js 版本
+- npm
+- Windows、Linux 或 macOS
+
+安装锁定依赖：
+
+```bash
+npm ci
+```
+
+不要将 API Key、访问令牌、私有模型地址或本地数据库提交到仓库。
+
+## 本地开发
+
+启动开发环境：
+
+```bash
+npm run dev
+```
+
+预览已经生成的生产构建：
+
+```bash
+npm run build
+npm start
+```
+
+## 质量验证
+
+提交或打包前运行：
+
+```bash
+npm test
+npm run typecheck
+npm run lint
+```
+
+监听模式：
+
+```bash
+npm run test:watch
+```
+
+真实 Runtime 端到端测试默认关闭。配置兼容模型凭据后，显式启用：
+
+```bash
+GOODBUDDY_RUN_RUNTIME_E2E=1 npm test -- src/main/agent/runtime-e2e.manual.test.ts
+```
+
+该测试可能发起真实外部模型调用。测试不会输出 API Key，文件操作在临时工作区中执行。
+
+## 生产构建
+
+生成 Electron Main、Preload 和 Renderer 生产文件：
+
+```bash
+npm run build
+```
+
+中间构建输出位于 `out`。该目录为生成内容，应修改源文件后重新构建，不要直接编辑。
+
+## 平台打包
+
+### 当前平台默认包
+
+```bash
+npm run dist
+```
+
+### Windows
+
+生成 Windows NSIS 安装包：
+
+```bash
+npm run dist:win
+```
+
+生成 Windows 便携目录：
+
+```bash
+npm run portable
+```
+
+### macOS
+
+生成 `x64` 和 `arm64` DMG：
+
+```bash
+npm run dist:mac
+```
+
+### Linux
+
+同时生成 Linux `x64` 和 `arm64` 包：
+
+```bash
+npm run dist:linux
+```
+
+只生成指定架构：
+
+```bash
+npm run dist:linux:x64
+npm run dist:linux:arm64
+```
+
+每个 Linux 架构生成：
+
+- `deb`：适用于麒麟、统信 UOS 等 Debian 系桌面。
+- AppImage：适用于免安装验证和便携运行。
+
+打包产物位于 `dist`。
+
+## Runtime 资源
+
+发布包会携带经过版本与完整性校验的 OpenCode 和 Continue Runtime：
+
+- OpenCode 平台二进制来自 `.runtime-resources/<arch>`。
+- Continue Runtime 来自锁定版本的 `@continuedev/cli`。
+- 打包钩子位于 `build/runtime-hooks.cjs`。
+
+跨架构打包前，确认目标架构的 OpenCode 资源已经准备完成。不要用其他架构的二进制替代目标资源。
+
+## Linux CI
+
+`.github/workflows/linux-packages.yml` 支持手动触发，也会在推送 `v*` 标签时构建 Linux 包。`x64` 与 `arm64` 应分别使用对应的原生 Linux Runner 完成构建和校验。
+
+## 发布前冒烟测试
+
+建议在每个目标系统上至少验证：
+
+1. 安装、启动、升级和卸载。
+2. 中文输入法、窗口缩放和高分屏显示。
+3. 系统密钥环和模型连接。
+4. 本地知识库导入、检索和知识图谱。
+5. Ask、Plan、Execute 的权限边界。
+6. OpenCode 与 Continue 的审批、取消和超时。
+7. 智能心跳的创建、暂停、恢复和历史记录。
+8. 应用退出后无残留 Runtime 子进程。

+# GoodBuddy
+
+面向专业工作与国产化环境的安全桌面智能助手。
+
+GoodBuddy 将模型连接、Agent Runtime、本地知识库、知识图谱、任务协作和持续成长能力组织在同一个桌面工作空间中。它不是简单的聊天窗口，而是一套可审计、可控制、可长期使用的个人智能工作环境。
+
+![GoodBuddy 工作空间](docs/screenshots/workspace-overview.png)
+
+## 为什么选择 GoodBuddy
+
+### 安全可控的 Agent 执行
+
+GoodBuddy 通过统一的 Agent Runtime 控制层接入直连模型、OpenCode 和 Continue。工具不会被直接暴露给界面，所有执行都受到工作模式、权限审批和运行边界约束。
+
+- `Ask`：只读问答，不调用写入工具。
+- `Plan`：先分析和制定计划，不修改工作区。
+- `Execute`：在用户授权范围内执行受控操作。
+- 支持拒绝、仅此次、当前会话和永久授权。
+- 统一处理取消、超时、输出边界、进程退出和异常恢复。
+
+### 数据主权与本地优先
+
+- 会话、任务、成果、记忆、知识库和图谱保存在本地 SQLite。
+- API Key 通过系统安全存储加密，不以明文写入配置。
+- Electron Main、Preload、Renderer 严格分层，Renderer 仅能使用类型化 IPC。
+- 子进程使用环境变量白名单，避免继承无关凭据。
+- 默认不依赖 GoodBuddy 云端账户，也不代理用户的模型流量。
+
+### 面向国产化环境交付
+
+- 支持 Windows、macOS 与 Linux。
+- 支持 Linux `x64` 和 `arm64`。
+- 提供适用于麒麟、统信 UOS 等 Debian 系桌面的 `deb` 安装包。
+- 提供 AppImage，便于免安装验证与便携分发。
+- 支持 Anthropic Messages、OpenAI Chat Completions、OpenAI Images 与无认证本机模型。
+- 可连接企业网关、私有模型服务和国产模型适配层。
+
+## 核心功能
+
+### 一体化智能工作空间
+
+- Projects 与独立对话上下文。
+- 专家角色和最多三个只读专家并行分析。
+- 任务、活动、成果、记忆和自动化集中管理。
+- 支持文件、桌面截图、应用窗口、剪贴板和语音上下文。
+- 显示真实 Git 工作区变更。
+- 支持远程任务委派与持久化结果发件箱。
+- Skills 与 MCP 能力按需接入。
+
+### 本地知识库与知识图谱
+
+文件、目录和网页内容可以按知识库独立管理。GoodBuddy 会完成解析、索引、检索和图谱构建，并保留可追溯的来源与证据。
+
+![GoodBuddy 知识工作区](docs/screenshots/knowledge-workspace.png)
+
+- SQLite FTS5 全文检索与有界上下文召回。
+- 支持规则、模型和混合图谱抽取。
+- 支持实体、关系、别名、证据与来源位置追溯。
+- 图谱可搜索、筛选、缩放和拖动节点。
+- 支持实体编辑、合并以及关系维护。
+- 文档解析包含压缩包展开限制、路径校验和敏感字段过滤。
+
+![GoodBuddy 知识图谱](docs/screenshots/knowledge-graph.png)
+
+### 智能心跳
+
+智能心跳让 GoodBuddy 不只响应当前问题，还能定期回顾近期工作，沉淀长期记忆，发现风险，并将洞察转化为可处理的建议。
+
+![GoodBuddy 智能心跳](docs/screenshots/smart-heartbeat.png)
+
+- 按项目或全局配置周期回顾计划。
+- 展示心跳健康、记忆沉淀、洞察发现和行动转化。
+- 提供成长趋势、最新报告和可审计的运行轨迹。
+- 建议记忆可确认或忽略。
+- 后续任务可带入 Plan 对话、标记完成或忽略。
+- 支持手动运行、暂停、恢复和安全删除计划。
+
+### 多 Runtime 与模型连接
+
+| 能力 | 适用场景 | 控制方式 |
+| --- | --- | --- |
+| 直连模型 | 问答、规划、知识总结、图像生成 | 协议校验，不开放本地工具 |
+| OpenCode | 完整编码与工作区任务 | 整次执行审批、受控目录与工具策略 |
+| Continue | 逐工具 Agent 任务 | 独立宿主、逐工具审批与隔离权限 |
+
+## 隐私说明
+
+模型请求只会发送到用户选择的模型连接。本地数据保存在当前系统的应用数据目录中；远程委派仅在用户显式配置 HTTPS 端点和令牌后启用。
