+# GridPilot Companion App - POC Guide
+
+## Overview
+
+The Electron companion app demonstrates the complete hosted session automation workflow with a visual interface, validating the Clean Architecture implementation through a functional proof-of-concept.
+
+## Quick Start
+
+### Prerequisites
+
+```bash
+npm install
+```
+
+### Running the POC
+
+```bash
+npm run companion:start
+```
+
+This command:
+1. Compiles TypeScript main process → `dist/main/`
+2. Builds React renderer with Vite → `dist/renderer/`
+3. Launches the Electron application
+
+## What You'll See
+
+### Left Panel: Session Configuration Form
+
+Pre-configured form with fields representing all 18 automation steps:
+- **Session Name** - Race session identifier
+- **Server Name** - Server configuration name
+- **Passwords** - Session and admin access credentials
+- **Max Drivers** - Capacity (1-60)
+- **Track** - Track selection (e.g., "watkins-glen")
+- **Cars** - Vehicle selection (e.g., "porsche-911-gt3-r")
+- **Weather Type** - Static or dynamic weather
+- **Time of Day** - Morning, afternoon, evening, or night
+- **Session Lengths** - Practice, qualifying, warmup, race durations
+- **Race Options** - Start type, restarts, damage model
+- **Track State** - Surface condition
+
+**Action**: Click "Start Automation" to begin the workflow
+
+### Right Panel: Live Progress Monitor
+
+Real-time visualization showing:
+- **Session ID** - Generated UUID
+- **Current Status** - Running/Completed/Failed/Stopped
+- **Step-by-Step Progress** - Visual indicators for all 18 steps:
+  - ✓ Green checkmark = Completed
+  - Blue number = Current step (in progress)
+  - Gray number = Pending
+- **Safety Notice** - Yellow warning at step 18 stop point
+- **Progress Counter** - "X / 18 steps" tracker
+
+## Expected Behavior
+
+### 1. Initial State
+- Form enabled with pre-filled POC defaults
+- Progress panel shows "Configure and start..." message
+
+### 2. Automation Started
+- Form becomes disabled
+- Button changes to "Automation Running..."
+- Progress panel shows "Running" status
+- Steps begin progressing: 1 → 2 → 3 → ... → 18
+
+### 3. Step Progression (Simulated)
+Each step takes ~500ms to complete:
+- **Step 1**: Navigate to Hosted Racing
+- **Step 2**: Click Create a Race  
+- **Step 3**: Fill Race Information
+- **Step 4**: Configure Server Details
+- **Step 5**: Set Admins
+- **Step 6**: Add Admin (modal step)
+- **Step 7**: Set Time Limits
+- **Step 8**: Set Cars
+- **Step 9**: Add Car (modal step)
+- **Step 10**: Set Car Classes
+- **Step 11**: Set Track
+- **Step 12**: Add Track (modal step)
+- **Step 13**: Configure Track Options
+- **Step 14**: Set Time of Day
+- **Step 15**: Configure Weather
+- **Step 16**: Set Race Options
+- **Step 17**: Configure Team Driving
+- **Step 18**: Set Track Conditions → **STOPS HERE**
+
+### 4. Step 18 Reached
+- Status changes to "Stopped at Step 18"
+- Yellow safety notice appears:
+  ```
+  ⚠️ Safety Stop
+  Automation stopped at step 18 (Track Conditions) as configured.
+  This prevents accidental session creation during POC demonstration.
+  ```
+- Form remains disabled
+- All 18 steps visible with completion status
+

+
+## POC Success Criteria
+
+✅ **Clean Architecture Preserved**
+- Zero business logic in UI components
+- Complete separation of concerns
+- All 158 existing tests still passing
+- Domain/application/infrastructure layers unchanged
+
+✅ **18-Step Workflow Visualized**
+- All steps from [`ROADMAP.md`](./ROADMAP.md:1) represented
+- Real-time progress updates every 100ms
+- State transitions validated by domain layer
+- Step execution tracked via domain entities
+
+✅ **Mock Adapters Functional**
+- Browser automation simulated with realistic delays
+- Session state persisted in-memory
+- Dependency injection wiring complete
+- Automation engine orchestrates workflow
+
+✅ **Electron Best Practices**
+- Context isolation enabled
+- Preload script for secure IPC
+- Main/renderer process separation
+- No node integration in renderer
+
+✅ **Safety Stop Demonstrated**
+- Automation stops at step 18 as designed
+- `STOPPED_AT_STEP_18` state properly displayed
+- Clear user communication about safety measure
+- No accidental session creation possible
+
+## Architecture Compliance
+
+### Boundaries Respected
+
+**Presentation Layer** (UI only):
+- React components render data
+- Electron IPC handles communication
+- No domain knowledge or business logic
+
+**Application Layer** (orchestration):
+- Use cases coordinate workflow
+- Port interfaces define contracts
+- No UI or infrastructure concerns
+
+**Domain Layer** (business rules):
+- Entities enforce invariants
+- Value objects validate states
+- Services implement domain logic
+- No dependencies on outer layers
+
+**Infrastructure Layer** (adapters):
+- Mock implementations for POC
+- Repository handles persistence
+- Automation adapters simulate browser
+- Ready to swap with real implementations
+
+### SOLID Principles Demonstrated
+
+- **Single Responsibility**: Each component has one clear purpose
+- **Open/Closed**: New adapters can be added without changing domain
+- **Liskov Substitution**: Mock adapters fully implement port interfaces
+- **Interface Segregation**: Clean port definitions, no fat interfaces
+- **Dependency Inversion**: All dependencies point inward via abstractions
+
+## Next Steps (Beyond POC)
+
+This POC validates the technical approach. For production:
+
+1. **Replace Mock Adapters**:
+   - Swap [`MockBrowserAutomationAdapter`](../src/infrastructure/adapters/automation/MockBrowserAutomationAdapter.ts:1) with `PuppeteerAdapter` or `PlaywrightAdapter`
+   - Replace [`InMemorySessionRepository`](../src/infrastructure/repositories/InMemorySessionRepository.ts:1) with `PostgreSQLSessionRepository`
+
+2. **Implement Real Automation**:
+   - Add actual browser control (Puppeteer/Playwright)
+   - Implement iRacing website interaction
+   - Handle real modals, forms, and navigation
+
+3. **Add Pause/Resume**:
+   - IPC handlers currently stubbed
+   - Implement session state management
+   - Add UI controls for pause/resume
+
+4. **Polish UI/UX**:
+   - Professional styling and branding
+   - Error recovery flows
+   - Better loading states
+
+5. **Production Features**:
+   - Auto-updater mechanism
+   - Crash reporting
+   - Logging and diagnostics
+   - User preferences storage
+
+## Troubleshooting
+
+### Build Fails
+
+```bash
+# Clean and rebuild
+rm -rf dist node_modules
+npm install
+npm run companion:build
+```
+
+### Electron Doesn't Start
+
+```bash
+# Verify build output exists
+ls dist/main/index.js        # Main process
+ls dist/renderer/index.html  # Renderer
+
+# Run directly
+electron dist/main/index.js
+```
+
+### Progress Not Updating
+
+- Open DevTools in Electron (View → Toggle Developer Tools)
+- Check browser console for errors
+- Verify IPC handlers registered
+- Check main process terminal output
+
+### TypeScript Errors
+
+```bash
+# Check configuration
+cat tsconfig.electron.json
+
+# Verify include paths match your structure
+npm run typecheck
+```

+
+## Conclusion
+
+This POC successfully demonstrates:
+- Clean Architecture principles in practice
+- Separation of concerns across all layers
+- Real-time automation workflow visualization
+- Safety controls preventing accidental actions
+- Foundation for production implementation
+
+All domain logic remains testable, maintainable, and independent of UI or infrastructure concerns. The 158 passing tests validate the core business rules remain intact.
