# Windows Tray Mode Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** 在现有 Windows 安装链路上新增独立 `tray.exe` 托盘控制层，同时让 `backend.exe` 暴露最小本机控制面，并通过本地引导文件闭环托盘对已运行后端的发现、控制和优雅退出。

**Architecture:** 保持 `backend.exe` 作为唯一运行时真源，继续负责真实端口、数据目录、日志、单实例、ready 状态和优雅退出；新增仅本机可用的 `status/stop` 控制面，并在 `{dataDir}/runtime-info.json` 写入真实控制地址与本机 secret。`tray.exe` 只做 Windows 托盘壳层、读取 `config.yaml` 与 `runtime-info.json`、按“status > process > lock”顺序判断状态，并编排 stop + spawn，不承担业务逻辑，也不成为第二个运行时中心。

**Tech Stack:** Midway.js 3.x、Koa、Jest + ts-jest、Node.js 22、Inno Setup 6、.NET 8 WinForms + xUnit

## File Structure

**Create**

- `packages/backend/src/comm/runtime-secret.ts` — 生成/校验托盘 secret，校验 loopback 访问
- `packages/backend/src/comm/runtime-state.ts` — 统一构建运行时状态对象，输出真实 URL、目录、PID、ready 状态
- `packages/backend/src/comm/runtime-info.ts` — 读写 `{dataDir}/runtime-info.json`，作为托盘首次发现的本地引导文件
- `packages/backend/src/comm/graceful-shutdown.ts` — 统一 shutdown coordinator，收口 stop endpoint、信号退出和锁清理
- `packages/backend/src/modules/base/controller/app/runtime.ts` — 以当前 `app` 控制器风格提供 `/base/runtime/status` 与 `/base/runtime/stop`
- `packages/backend/src/modules/base/service/runtime.ts` — 本机运行时控制服务，封装状态读取与停止调用
- `packages/backend/test/windows-tray/runtime-secret.test.ts` — secret 与 loopback 校验测试
- `packages/backend/test/windows-tray/runtime-state.test.ts` — 状态对象与 URL 生成测试
- `packages/backend/test/windows-tray/runtime-info.test.ts` — 本地引导文件读写测试
- `packages/backend/test/windows-tray/runtime-controller.test.ts` — 本机控制面服务测试
- `packages/windows-tray/Neta.Tray/Neta.Tray.csproj` — 托盘程序工程
- `packages/windows-tray/Neta.Tray/Program.cs` — 进程入口，支持正常托盘模式与 `--shutdown` 无界面停机模式
- `packages/windows-tray/Neta.Tray/TrayApplicationContext.cs` — NotifyIcon、菜单、状态切换
- `packages/windows-tray/Neta.Tray/BackendProcessManager.cs` — 启动后端、探测已有进程、兜底结束残留进程
- `packages/windows-tray/Neta.Tray/RuntimeInfoStore.cs` — 读取 `config.yaml` 和 `runtime-info.json`

- `packages/windows-tray/Neta.Tray.Tests/RuntimeInfoStoreTests.cs` — 引导文件发现与解析测试
- `packages/windows-tray/Neta.Tray.Tests/StatusClientTests.cs` — 状态解析与 stop 调用测试

**Modify**

- `packages/backend/bootstrap.js` — 解析 `--tray-secret`、`--no-browser`，把 secret 注入环境
- `packages/backend/src/configuration.ts` — 注册统一 shutdown coordinator、维护 ready/startTime、写入并清理 `runtime-info.json`
- `packages/backend/src/config/config.default.ts` — `autoOpenBrowser` 读取 `NETA_NO_BROWSER` 覆盖

- `packages/backend/installer/setup.iss` — 安装 `tray.exe`，快捷方式和开机自启改指向 `tray.exe`，卸载先调用 `tray.exe --shutdown`
- `packages/backend/README.md` — 补充 `.NET 8 SDK` 打包前置条件、托盘模式产物和验证步骤

Run:
```bash
cd /c/Users/Administrator/Desktop/code/Neta-monorepo && dotnet test packages/windows-tray/Neta.Tray.Tests/Neta.Tray.Tests.csproj
```

Expected: FAIL，提示状态请求尚未通过 `runtime-info.json` 的 `ControlBaseUrl` 驱动。

```

### Task 5: 接入 Windows 打包链路与优雅卸载入口

**Files:**
- Modify: `packages/backend/scripts/build-windows-installer.js`
- Modify: `packages/backend/installer/setup.iss`
- Modify: `packages/backend/README.md`

- [ ] **Step 1: 先写构建断言，确保产物不再只有 backend.exe**

```js
// packages/backend/scripts/build-windows-installer.js
const trayOutputDir = path.join(backendDir, 'build', 'tray-output');
const trayExePath = path.join(trayOutputDir, 'tray.exe');
if (!fs.existsSync(trayExePath)) {
  throw new Error(`缺少托盘产物: ${trayExePath}`);
}
```

- [ ] **Step 2: 运行安装器构建确认当前失败**

Run:
```bash
cd /c/Users/Administrator/Desktop/code/Neta-monorepo/packages/backend && node scripts/build-windows-installer.js
```

Expected: FAIL，提示缺少 `tray.exe`。

- [ ] **Step 3: 补齐 `dotnet publish` 与优雅卸载入口**

```js
// packages/backend/scripts/build-windows-installer.js
const repoDir = path.resolve(backendDir, '..', '..');
const trayProject = path.join(repoDir, 'packages', 'windows-tray', 'Neta.Tray', 'Neta.Tray.csproj');
const trayOutputDir = path.join(backendDir, 'build', 'tray-output');

if (!fs.existsSync(path.join(outputDir, 'backend.exe'))) {
  cp.execFileSync('node', ['scripts/pkg-build.js'], { cwd: backendDir, stdio: 'inherit' });
}

fs.rmSync(trayOutputDir, { recursive: true, force: true });
cp.execFileSync(
  'dotnet',
  [
    'publish',
    trayProject,
    '-c', 'Release',
    '-r', 'win-x64',
    '--self-contained', 'true',
    '/p:PublishSingleFile=true',
    '/p:PublishTrimmed=false',
    '-o', trayOutputDir,
  ],
  { cwd: repoDir, stdio: 'inherit' }
);

const publishedTrayExePath = path.join(trayOutputDir, 'Neta.Tray.exe');
if (!fs.existsSync(publishedTrayExePath)) {
  throw new Error(`缺少托盘产物: ${publishedTrayExePath}`);
}
```

<!-- packages/backend/README.md -->
### 4. .NET 8 SDK

生成 `tray.exe` 需要安装 .NET 8 SDK。

```bash
winget install Microsoft.DotNet.SDK.8
```

### Windows 托盘模式产物

完成构建后应同时看到：

```text
packages/backend/build/pkg-output/backend.exe
packages/backend/build/tray-output/Neta.Tray.exe
packages/backend/build/installer-output/neta-setup.exe
```

### Windows 托盘模式验证

```bash
npm run build:windows-installer
```

验证点：
- `tray.exe` 能读取 `config.yaml` 与 `runtime-info.json`
- 卸载时优先调用 `tray.exe --shutdown`
- 仅在优雅停机失败时才兜底 `taskkill`
```

- [ ] **Step 4: 运行打包命令确认新链路通过**

Run:
```bash
cd /c/Users/Administrator/Desktop/code/Neta-monorepo/packages/backend && npm run build:windows-installer
```

Expected: PASS，同时产出 `backend.exe`、`Neta.Tray.exe` 和 `neta-setup.exe`。

- [ ] **Step 5: 提交打包与安装器改动**

```bash
git add packages/backend/scripts/build-windows-installer.js packages/backend/installer/setup.iss packages/backend/README.md
git commit -m "feat: package windows tray installer"
```

### Task 6: 最终验证与回归检查

**Files:**
- Test: `packages/backend/test/windows-tray/runtime-secret.test.ts`
- Test: `packages/backend/test/windows-tray/runtime-state.test.ts`
- Test: `packages/backend/test/windows-tray/runtime-info.test.ts`
- Test: `packages/backend/test/windows-tray/runtime-controller.test.ts`
- Test: `packages/windows-tray/Neta.Tray.Tests/BackendProcessManagerTests.cs`
- Test: `packages/windows-tray/Neta.Tray.Tests/RuntimeInfoStoreTests.cs`
- Test: `packages/windows-tray/Neta.Tray.Tests/StatusClientTests.cs`

- [ ] **Step 1: 跑 backend 相关单元测试**

Run:
```bash
cd /c/Users/Administrator/Desktop/code/Neta-monorepo/packages/backend && npx jest test/windows-tray/runtime-secret.test.ts test/windows-tray/runtime-state.test.ts test/windows-tray/runtime-info.test.ts test/windows-tray/runtime-controller.test.ts test/windows-installer/config-loader.test.ts test/windows-installer/data-dir.test.ts test/windows-installer/runtime-lock.test.ts -i
```

Expected: PASS，Windows tray 与 installer 基础设施测试全部通过。

- [ ] **Step 2: 跑托盘 .NET 单元测试**

Run:
```bash
cd /c/Users/Administrator/Desktop/code/Neta-monorepo && dotnet test packages/windows-tray/Neta.Tray.Tests/Neta.Tray.Tests.csproj
```

Expected: PASS，托盘引导发现、状态轮询和进程编排测试全部通过。

- [ ] **Step 3: 做一次 Windows 手工 smoke**

Run:
```bash
cd /c/Users/Administrator/Desktop/code/Neta-monorepo/packages/backend && npm run build:windows-installer
```

Manual check list:

```text
1. 安装 neta-setup.exe 后，桌面快捷方式指向 tray.exe
2. 双击快捷方式后，系统托盘出现图标
3. tray.exe 能通过 config.yaml + runtime-info.json 附着或拉起 backend.exe
4. “打开系统”能打开 backend 状态接口返回的真实 URL
5. “停止服务”后，backend.exe 退出，托盘仍在
6. “重启服务”后，backend.exe 被重新拉起
7. “打开日志目录 / 打开配置目录”路径正确
8. “退出程序”后，tray.exe 与 backend.exe 都退出
9. 卸载时先尝试 tray.exe --shutdown，再兜底强杀
10. 卸载后程序目录清理正常，数据目录按现有策略保留
```

Expected: 所有 10 项都满足。

- [ ] **Step 4: 做最终提交**

```bash
git add packages/backend packages/windows-tray
git commit -m "feat: add windows tray mode"
```

---

## Self-Review

### Spec coverage

- “backend 是唯一运行时真源” → Task 1、Task 2
- “最小控制面仅 status/stop” → Task 2
- “首次发现依赖 runtime-info.json” → Task 1、Task 3、Task 4
- “tray 负责 stop + spawn，不承担 restart API” → Task 3、Task 4
- “状态判断优先级：status > process > lock” → Task 4
- “installer 入口改为 tray.exe，卸载优先 graceful shutdown” → Task 5
- “.NET 8 SDK 为新前置条件” → Task 5
- “数据库安全、ProgramData、Windows Service、自动更新不做” → 计划中未新增对应任务，保持收口

### Placeholder scan

- 无 `TBD`、`TODO`、`implement later`
- 每个测试步骤都包含具体测试代码、命令和预期结果
- 每个代码步骤都给出目标文件与最小实现代码

### Type consistency

- backend 统一使用 `RuntimeService`、`buildRuntimeStatus`、`RuntimeInfo`、`triggerGracefulShutdown`
- tray 统一使用 `BackendProcessManager`、`RuntimeInfoStore`、`StatusClient`、`RuntimeBootstrapInfo`
- `restart` 只在 `TrayApplicationContext` 中作为 stop + spawn 编排动作出现，没有在 backend 中定义 restart API
