## Forensic Analysis Methodology

### Matching Approach
1. **Symmetric ±10 minute window** - Payment can occur before OR after DB order entry
2. **Split payment detection** - Multiple Revolut payments summing to DB amount
3. **10x keying error detection** - Staff typing wrong number of zeros
4. **Per-ticket validation** - Verify discount reasonableness by ticket count

### Key Findings

**69 of 76 POS orders matched (90.8%)**

| Match Type | Orders | DB Amount | Revolut |
|------------|--------|-----------|---------|
| Exact (±5%) | 30 | £66,250 | £66,250 |
| Negotiated | 35 | £93,700 | £43,685 |
| Over-collected | 4 | £5,050 | £8,200 |

**Split Payments Identified:**
- #744 atheer: 5 payments = £5,500 ≈ £5,550 DB (NOT keying error)
- #764 nouf: 4 payments = £1,000 ≈ £1,100 DB (NOT keying error)

**Confirmed Keying Error:**
- #701 hessa: £300 typed instead of £3,000 (3 BLUE tickets @ £100/tkt = impossible)

## Tools Created

### 1. Database Cleanup Command
**File:** `app/Console/Commands/AuditCleanupCommand.php`
```bash
php artisan audit:cleanup --dry-run     # Preview changes
php artisan audit:cleanup --backup      # Apply with backup
php artisan audit:cleanup --section=X   # Run specific section
```

**Sections:**
- `duplicates` - Cancel orders 522, 523 (empty shells)
- `mislabeled` - Fix order 568 (stripe→revolut), 530 (add Revolut ID)
- `pos-links` - Link 42 POS orders to Revolut payments
- `test-orders` - Mark 16 test orders

### 2. Reconciliation Report Command
**File:** `app/Console/Commands/AuditReconciliationCommand.php`
```bash
php artisan audit:reconciliation              # Console output
php artisan audit:reconciliation --export=json
php artisan audit:reconciliation --export=csv
```

### 3. Google Sheets Export Command
**File:** `app/Console/Commands/ExportFinancialsCommand.php`
```bash
php artisan export:financials
```

**Exports 5 CSVs:**
- `orders_all_{timestamp}.csv` - All orders with categorization
- `revenue_by_channel_{timestamp}.csv` - Channel breakdown
- `reconciliation_summary_{timestamp}.csv` - High-level summary
- `issues_requiring_attention_{timestamp}.csv` - Problem orders
- `revolut_matching_{timestamp}.csv` - POS verification status

### 4. Root Cause Analysis Document
**File:** `docs/PAYMENT_ROOT_CAUSE_ANALYSIS.md`

**Root Causes Identified:**
1. POS Air-Gap (manual amount entry) - £46,865 impact
2. Payment Method Mislabeling - £51,800+ impact
3. Incomplete Payment Integrations (Stripe abandoned, PayPal 501)
4. Test Data in Production - £2,575

## Orders Requiring Action

### Test Orders (16) - Mark as test
```
613, 627, 653, 662, 671, 672, 680, 681,
682, 683, 684, 685, 705, 765, 766, 767
```

### Duplicate Orders (2) - Cancel
```
522, 523 (duplicates of 530)
```

### Mislabeled Orders (2) - Fix payment_method
```
568: stripe → revolut (Arwa Zawawi)
530: Add correct revolut_payment_id (Talal)
```

### POS-Revolut Links (42) - Add revolut_payment_id
Orders linked by amount+timestamp forensic matching.

### Unmatched DB Orders (7) - Staff verification needed
```
#752 Ahmed Abuobaid    £6,650
#691 Mohammed Alothman £4,350
#668 Sheikh Zayed      £4,000
#753 Ahmed Abuobaid    £3,700
#704 mariam omar       £2,000
#739 Khaled Al anzi    £2,000
#748 Fares Almeaile    £1,850
```

## Next Steps

### Immediate (Run Locally)
1. `./scripts/backup-db.sh`
2. `php artisan audit:cleanup --dry-run`
3. `php artisan audit:cleanup`
4. `php artisan audit:reconciliation`
5. `php artisan export:financials`

### After Verification
1. Apply same cleanup to production
2. Update admin dashboard queries
3. Implement code fixes from root cause analysis

### Future Events
1. Integrate Revolut Reader with POS (auto-populate amounts)
2. Add `is_test` flag to orders schema
3. Implement real-time reconciliation alerts
4. Complete or remove PayPal integration

## Dashboard Fix Required

Current: `https://admin.globalgala.com/orders` shows £1,027,550.01

**Issues:**
- Includes test orders (£2,575)
- Includes duplicates (£51,800)
- Includes abandoned/pending (£303,500 "stripe_abandoned")
- Different status filters across controllers

**Fix:** Update queries to:
1. Exclude `is_test = true` (after adding flag)
2. Exclude `status IN ('cancelled', 'voided', 'failed', 'expired')`
3. Exclude orders in `testOrderIds` array
4. Use consistent status filter (`payment_status = 'paid'`)
