+# Electron Decoupling Audit
+
+> Дата аудита: 2026-03-08
+
+## Executive Summary
+
+Кодовая база **на 68% независима от Electron**. Только 30 из 692 файлов имеют прямые Electron импорты. Миграция оценивается в 4-6 недель, в основном механический рефакторинг.
+
+## Структура кодовой базы
+
+| Категория | Файлов | % | Electron-зависимость |
+|-----------|:------:|:-:|---------------------|
+| Renderer (React) | 473 | 68% | Нет — pure React, работает в браузере |
+| Main (Services) | ~140 | 20% | Минимальная — pure Node.js |
+| Main (IPC handlers) | 22 | 3% | Да — `ipcMain.handle()` |
+| Main (Electron APIs) | 8 | 1% | Да — BrowserWindow, app, dialog, shell |
+| Preload | 2 | 0.3% | Да — contextBridge |
+| Shared (types/utils) | 45 | 6.5% | Нет — полностью agnostic |
+
+## Уже реализованная инфраструктура отвязки
+
+### 1. HTTP Server (Fastify)
+- **Файл**: `src/main/services/infrastructure/HttpServer.ts` (179 LOC)
+- Работает на `127.0.0.1:3456`
+- Раздаёт статику + API роуты
+- CORS настроен для standalone режима
+
+### 2. HTTP Routes (80% покрытие)
+- **Директория**: `src/main/http/`
+- 13 файлов роутов, дублируют IPC handlers:
+  - projects, sessions, search, subagents
+  - config, notifications, utility, validation
+  - ssh, updater, events, schedule
+
+### 3. HttpAPIClient
+- **Файл**: `src/renderer/api/httpClient.ts` (400+ LOC)
+- Полная имплементация `ElectronAPI` интерфейса
+- EventSource (SSE) для real-time событий
+- Fetch для request/response
+
+### 4. Unified API Proxy
+- **Файл**: `src/renderer/api/index.ts`
+- Автоматически переключается между:
+  - `window.electronAPI` (Electron mode)
+  - `HttpAPIClient` (browser mode)
+- Прозрачно для всех компонентов
+
+### 5. Standalone Entry Point
+- **Файл**: `src/main/standalone.ts`
+- Запускает HTTP сервер без Electron
+- Стабит UpdaterService, SshConnectionManager
+- Протестирован и работает
+
+## 30 файлов с Electron импортами
+
+### ipcMain (22 файла)

+src/preload/index.ts                                 — contextBridge, ipcRenderer
+```
+
+## Замена каждого Electron API
+
+| API | Файлов | Замена | Усилия |
+|-----|:------:|--------|:------:|
+| `ipcMain.handle()` | 22 | HTTP роуты (80% уже есть) | 3-4ч |
+| `BrowserWindow` | 6 | Убрать (браузер сам управляет) | 1-2ч |
+| `app` lifecycle | 2 | Прямой запуск Node.js сервера | 4-5ч |
+| `dialog.showOpenDialog()` | 1 | HTML `<input type="file">` / env var | 3ч |
+| `shell.openExternal/Path` | 1 | `window.open()` / убрать | 1ч |
+| `Notification` | 2 | Browser Notification API | 2ч |
+| `electron-updater` | 1 | GitHub releases redirect | 2ч |
+| `contextBridge` | 1 | Убрать полностью | 1ч |
+
+## Оценка миграции
+
+| Метрика | Значение |
+|---------|----------|
+| Сложность | 6/10 — механический рефакторинг |
+| Объём работы | 4-6 недель |
+| Вероятность успеха | 95% |
+| Уверенность в оценке | 9/10 |
+
+## Фазы миграции
+
+### Phase 1: Setup (2-3 дня)
+- Рефакторинг `src/main/index.ts` в pure HTTP server bootstrap
+- Удаление Electron app lifecycle
+- HTTP server как primary entry point
+
+### Phase 2: IPC → HTTP (3-4 дня)
+- Завершить оставшиеся HTTP роуты (~20%)
+- Удалить все `ipcMain.handle()` вызовы
+- SSE для event delivery
+
+### Phase 3: Desktop-Only Features (2-3 дня)
+- Убрать auto-updater → version check API
+- Убрать dialog → env var / HTML input
+- Убрать shell → client-side links
+- Browser Notification API
+
+### Phase 4: Build System (2-3 дня)
+- `electron-vite` → стандартный Vite
+- Убрать preload bundling
+- Docker build config
+
+### Phase 5: Testing (2-3 дня)
+- HTTP endpoint coverage
+- Browser compatibility
+- Docker deployment
+
+## Что нельзя заменить (Electron-only)
+- Auto-update бинарных патчей → GitHub releases
+- System tray → убрать
+- Native menu → web context menus
+- System hotkeys → browser keyboard events
+- Native file dialogs → HTML file input
+
+## Build изменения
+
+**Текущий:**
+```json
+"dev": "electron-vite dev",
+"build": "electron-vite build",
+"dist": "electron-builder --mac --win --linux"
+```
+
+**После миграции:**
+```json
+"dev": "tsx src/main/standalone.ts & vite",
+"build": "vite build && tsc --noEmit",
+"start": "node dist/main/index.cjs",
+"docker": "docker build -t claude-teams ."
+```
