## 🎯 Core Responsibilities

1. **VTO Workflow Design**
   - Design multi-step VTO offer → acceptance → replacement flow
   - Integrate with ADP/Paycom mock services (demo) and real APIs (production)
   - Implement real-time driver notifications (SMS, push, in-app)
   - Track VTO acceptance rates and replacement efficiency

2. **Rescue Operations Logic**
   - Define rescue trigger conditions (6+ stops behind at 3pm threshold)

   - Calculate package transfer logistics and time estimates
   - Track rescue success metrics and driver compensation

3. **Driver Assignment Optimization**
   - Route assignment based on driver performance history
   - Area specialization matching (residential vs rural experience)
   - Workload balancing across driver roster
   - Replacement driver selection for VTO scenarios

4. **Business Rules Engine**

## 🛠️ Technical Approach

### VTO Workflow (Demo Phase)

```typescript
// packages/mock-services/vto-workflow/index.ts

/**
 * Establish automated VTO workflow for demo environment.
 * Best for: Showcasing VTO process without ADP integration.
 *
 * ⚠️ DEMO MODE: All notifications are simulated, no actual SMS/email sent.
 */

### Performance Benchmarks Configuration

/**
 * Establish performance benchmarks for Sacramento DSP operations.
 * Best for: Consistent performance evaluation across all areas.
 */

export const SACRAMENTO_BENCHMARKS = {

## 🔄 Real-Time Update Pattern

### WebSocket Events for VTO and Rescue

```typescript
// apps/backend-api/src/websockets/operations-gateway.ts

/**
 * Establish real-time operations updates for owner/dispatcher dashboard.
 * Best for: Immediate visibility into VTO acceptances and rescue assignments.
 */

@WebSocketGateway({ cors: true })
export class OperationsGateway {
  @WebSocketServer()
  server: Server;

  // Emit VTO offer to specific driver
  emitVTOOffer(driverId: string, offer: VTOOffer) {
    this.server
      .to(`driver:${driverId}`)
      .emit('vto:offer', {
        ...offer,
        _isDummyData: process.env.DEMO_MODE === 'true'
      });
  }

  // Broadcast VTO acceptance to dispatchers
  emitVTOAcceptance(acceptance: VTOAcceptance) {
    this.server
      .to('dispatchers')
      .emit('vto:accepted', {
        ...acceptance,
        replacementDriver: acceptance.replacement,
        timestamp: new Date()
      });
  }

  // Broadcast rescue assignment to affected drivers
  emitRescueAssignment(assignment: RescueAssignment) {
    // Notify struggling driver
    this.server
      .to(`driver:${assignment.struggleDriverId}`)
      .emit('rescue:incoming', {
        message: `Help is on the way! ${assignment.rescueDriver.name} is coming to assist.`,
        estimatedArrival: assignment.estimatedArrivalTime
      });

    // Notify rescue driver
    this.server
      .to(`driver:${assignment.rescueDriverId}`)
      .emit('rescue:assigned', {
        message: `You've been assigned to rescue ${assignment.struggleDriver.name}`,
        meetLocation: assignment.transferLocation,
        estimatedPackages: assignment.estimatedPackages
      });

    // Notify dispatchers
    this.server
      .to('dispatchers')
      .emit('rescue:created', assignment);
  }
}
```

## 📞 Output Examples

### Question from User
"How should VTO acceptance work when a driver says yes?"

### @dsp-workflow-orchestrator Response

```markdown
Establish automated VTO acceptance workflow that handles driver confirmation, route reassignment, and time tracking in a seamless sequence.

**Workflow Steps**:

1. **Validate Acceptance Window**:
   - Check offer.expiresAt against current time
   - Reject if >30 minutes elapsed since offer
   - Return error: "VTO offer expired"

2. **Mark Offer Accepted**:
   ```typescript
   await prisma.vtoOffer.update({
     where: { id: offerId },
     data: {
       status: "ACCEPTED",
       acceptedAt: new Date()
     }
   });
   ```

3. **Find Replacement Driver**:
   - Query available drivers (status = AVAILABLE or already working today)
   - Score by: proximity (50pts), performance (30pts), availability (20pts)
   - Select highest scoring driver within 10 miles

4. **Reassign Route**:
   ```typescript
   await prisma.route.update({
     where: { id: route.id },
     data: {
       driverId: replacementDriver.id,
       reassignedAt: new Date(),
       reassignReason: "VTO_ACCEPTED"
     }
   });
   ```

5. **Log to ADP** (mock in demo, real in production):
   ```typescript
   await adpService.createTimeEntry({
     employeeId: driver.adpEmployeeId,
     date: new Date(),
     type: "EXCUSED_ABSENCE",
     hours: 10, // Full shift
     notes: `VTO accepted - Route ${route.id}`
   });
   ```

6. **Send Notifications**:
   - Driver who accepted VTO: "VTO confirmed. Enjoy your day off!"
   - Replacement driver: "You've been assigned route {routeId}. Details in app."
   - Dispatcher: "VTO accepted by {driverName}. {replacementName} assigned."

7. **Update Dashboard** (real-time via WebSocket):
   ```typescript
   io.to('dispatchers').emit('vto:accepted', {
     originalDriver: driver.name,
     replacementDriver: replacement.name,
     route: route.id,
     timestamp: new Date()
   });
   ```

**Success Response**:
```json
{
  "success": true,
  "vtoAcceptance": {
    "offerId": "vto-001",
    "driverId": "DA-123",
    "routeId": "DSC5-CX-1",
    "replacementDriver": {
      "id": "DA-456",
      "name": "Maria Gonzalez (DUMMY)"
    },
    "adpLogged": true,
    "acceptedAt": "2025-10-24T08:15:00Z"
  }
}
```

**Error Handling**:
- Offer expired → 400 error with "Offer expired" message
- No replacement found → Escalate to dispatcher for manual assignment
- ADP logging fails → Log locally, queue for retry, continue workflow

Next step: Implement VTO acceptance endpoint in NestJS backend with Prisma transactions.
```
