# Commit 2: Gateway Refinements

## Summary
Enhance Gateway process management with auto-reconnection, health checks, and improved state management for more robust WebSocket communication.

## Changes

### Electron Main Process

#### `electron/gateway/manager.ts`
- Added `'reconnecting'` state to `GatewayStatus`
- Implemented `ReconnectConfig` with exponential backoff strategy
- Added `maxAttempts`, `baseDelay`, `maxDelay` configuration
- New methods:
  - `isConnected()` - Check WebSocket connection status
  - `restart()` - Stop and start Gateway
  - `clearAllTimers()` - Clean up timers on shutdown
  - `startHealthCheck()` - Periodic health monitoring
  - `checkHealth()` - Manual health check
- Enhanced `handleMessage()` to dispatch JSON-RPC responses and notifications
- Expanded `GatewayManagerEvents` for notification forwarding

#### `electron/gateway/client.ts`
- Extended with new interfaces: `SkillBundle`, `CronTask`, `ProviderConfig`
- Added cron task management methods:
  - `listCronTasks()`, `createCronTask()`, `updateCronTask()`, `deleteCronTask()`, `runCronTask()`
- Added provider management methods:
  - `listProviders()`, `setProvider()`, `removeProvider()`, `testProvider()`
- Enhanced system calls:
  - `getHealth()` now includes `version`
  - Added `getVersion()`, `getSkillBundles()`, `installBundle()`

#### `electron/main/ipc-handlers.ts`
- Added `gateway:isConnected`, `gateway:health` IPC handlers
- Added `mainWindow.isDestroyed()` checks before sending events
- Forward new gateway events: `gateway:notification`, `gateway:channel-status`, `gateway:chat-message`

#### `electron/preload/index.ts`
- Added new IPC channels for gateway operations
- Added notification event channels

### React Renderer

#### `src/stores/gateway.ts`
- Added `health: GatewayHealth | null`, `lastError: string | null` to state
- Added `checkHealth()`, `rpc()`, `clearError()` actions
- Enhanced `init()` to listen for error and notification events

#### `src/types/gateway.ts`
- Added `'reconnecting'` to `GatewayStatus` state enum
- Added `version`, `reconnectAttempts` fields
- New interfaces: `GatewayHealth`, `GatewayNotification`, `ProviderConfig`

#### `src/components/common/StatusBadge.tsx`
- Added `'reconnecting'` status with warning variant

## Technical Details

### Reconnection Strategy
- Exponential backoff: `delay = min(baseDelay * 2^attempt, maxDelay)`
- Default: 1s base delay, 30s max delay, 10 max attempts
- Automatic reconnection on unexpected disconnection
- Manual control via `shouldReconnect` flag

### Health Check
- Periodic ping/pong via JSON-RPC `system.health`
- Returns status, uptime, version information
- Triggers reconnection on consecutive failures

### Event Flow
```
Gateway Process -> WebSocket -> GatewayManager -> IPC -> Renderer
                                    |
                                    v
                              Event Emitter
                                    |
                    +---------------+---------------+
                    |               |               |
                 status        notification     channel:status
```
