## 🔧 Technical Details

### Database Schema

#### New Table: `mod_visit_recurrence_rules`
```sql
- id (bigint, PK)
- contract_id (FK → mod_maintenance_contracts)
- addendum_id (FK → mod_contract_addendums)
- maintenance_project_id (FK → mod_maintenance_projects)
- recurrence_type (enum: weekly, monthly, specific_dates, custom)
- frequency (int)
- specific_days (json)
- recurrence_config (json)
- total_visits (int)
- visits_generated (int)
- start_date (date)
- end_date (date)
- is_active (boolean)
- timestamps, soft_deletes
```

#### Updated: `mod_maintenance_visits`
```sql
+ is_scheduled (boolean, default: false)
+ planned_date (date, nullable)
+ visit_sequence (int, nullable)
+ recurrence_rule_id (FK → mod_visit_recurrence_rules, nullable)
```

#### Updated: `mod_contract_addendums`
```sql
+ visit_generation_mode (enum: manual, automatic, default: automatic)
```

## 🎨 Recurrence Patterns Supported

### 1. Weekly
```json
{
  "recurrence_type": "weekly",
  "frequency": 2
}
```
**Result:** Visit every 2 weeks

### 2. Monthly
```json
{
  "recurrence_type": "monthly",
  "frequency": 1
}
```
**Result:** One visit per month

### 3. Specific Dates
```json
{
  "recurrence_type": "specific_dates",
  "specific_days": [1, 15]
}
```
**Result:** 1st and 15th of each month

### 4. Custom
```json
{
  "recurrence_type": "custom",
  "recurrence_config": { /* flexible config */ }
}
```
**Result:** Extensible for future patterns

## 🔄 Workflow Examples

### Automatic Generation Flow
```
1. Create Contract
   └─ Add Addendums with number_of_visits = 12
      └─ Set visit_generation_mode = 'automatic'

2. Approve Contract
   └─ MaintenanceContractApproved Event Fired
      └─ GenerateVisitsFromContract Listener Executes
         └─ Creates Recurrence Rule (monthly, 12 visits)
            └─ Generates 12 Planned Visits

3. Result: 12 visits with is_scheduled = false
```

### Manual Scheduling Flow
```
1. View Planned Visits
   GET /api/maintenance/visits/planned

2. Select Visit(s)

3. Schedule
   POST /api/maintenance/visits/{id}/schedule
   {
     "scheduled_at": "2026-02-01 09:00",
     "technician_ids": [1, 2]
   }

4. Result: is_scheduled = true, technicians assigned
```

## 🚀 Ready for Production

### Pre-Production Checklist

- [x] All features implemented
- [x] All tests passed
- [x] Database migrations verified
- [x] API endpoints tested
- [x] Documentation complete
- [x] Backward compatibility verified
- [x] Event system operational
- [x] No breaking changes
- [x] Error handling implemented
- [x] Validation in place

### Deployment Notes

1. **No additional configuration needed** - Event listener already registered in existing `MaintenanceEventsServiceProvider`
2. **Migrations already run** - Tables are ready
3. **Backward compatible** - Existing visits marked as scheduled automatically
4. **Permissions** - Uses existing `maintenance.visits.*` permissions

---

## 📈 Performance Notes

- **Database Indexes**: Added on key fields (is_scheduled, recurrence_rule_id)
- **Transaction Safety**: All multi-step operations wrapped in DB transactions
- **Locking**: Visit number generation uses DB locking for thread safety
- **Efficient Queries**: Scopes use indexed fields
- **Batch Operations**: Bulk scheduling processes efficiently

---

## 🎯 Next Steps (Optional Enhancements)

Future enhancements that could be added:

1. **Notifications** - Alert technicians when visits are scheduled
2. **Calendar Integration** - Sync with Google Calendar/Outlook
3. **Mobile App** - Technician mobile interface
4. **Analytics** - Visit completion rates, SLA compliance reports
5. **AI Scheduling** - Smart scheduling based on technician availability
6. **Conflict Detection** - Prevent double-booking technicians

---

## 🆘 Support

### If Issues Arise

1. **Check Logs**: `storage/logs/laravel.log`
   - Search for: "Generated visits for project"
   - Check for event listener execution

2. **Verify Migrations**:
   ```bash
   php artisan migrate:status | grep "mod_visit\|recurrence"
   ```

3. **Test Services**:
   ```php
   php artisan tinker
   >>> $service = app(\App\Domains\Maintenance\SubDomains\Visits\Services\VisitRecurrenceService::class);
   >>> $dates = $service->previewVisitDates([...]);
   ```

4. **Check Routes**:
   ```bash
   php artisan route:list | grep "recurrence\|planned"
   ```
