# Field Config vs Raw Types - Audit Report

## Audit Objective
Verify that all fields referenced in the field config system actually exist in the raw type schemas before removing the field config abstraction layer.

## 🚨 CRITICAL FINDINGS

### Missing Fields in Raw Types:

#### 1. **MNP (Mobile Number Portability) Fields**
Field config expects these but they're **NOT in raw type**:
```typescript
mnp: {
  application: string,
  reservationNumber: string,
  expiryDate: string,
  phoneNumber: string,
  mvnoAccountNumber: string,
  portingDateOfBirth: string,
  portingFirstName: string,
  portingLastName: string,
  portingFirstNameKatakana: string,
  portingLastNameKatakana: string,
  portingGender: string,
}
```

**These should be:**
```typescript
MNP_Application__c?: string
MNP_Reservation_Number__c?: string
MNP_Expiry_Date__c?: string
MNP_Phone_Number__c?: string
MVNO_Account_Number__c?: string
Porting_Date_Of_Birth__c?: string
Porting_First_Name__c?: string
Porting_Last_Name__c?: string
Porting_First_Name_Katakana__c?: string
Porting_Last_Name_Katakana__c?: string
Porting_Gender__c?: string
```

#### 2. **Billing Address Fields**
Field config expects these but they're **NOT in raw type**:
```typescript
billing: {
  street: string,
  city: string,
  state: string,
  postalCode: string,
  country: string,
}
```

**These should be:**
```typescript
Billing_Street__c?: string
Billing_City__c?: string
Billing_State__c?: string
Billing_Postal_Code__c?: string
Billing_Country__c?: string
```

#### 3. **Other Missing Fields:**
```typescript
lastAttemptAt    → Activation_Last_Attempt_At__c?
addressChanged   → Address_Changed__c?
```

## Impact Analysis

### **Used in Order Builder** (Order Creation)
The order builder **DOES use** MNP and billing fields when creating orders:

```typescript
// apps/bff/src/modules/orders/services/order-builder.service.ts

private addSimFields(...) {
  // Uses MNP fields if configurations.isMnp === "true"
  orderFields[mnpField("application", fieldMap)] = ...
  orderFields[mnpField("phoneNumber", fieldMap)] = ...
  // etc.
}

private async addAddressSnapshot(...) {
  // Uses billing fields for address snapshot
  orderFields[billingField("street", fieldMap)] = ...
  orderFields[billingField("city", fieldMap)] = ...
  // etc.
}
```

### **Used in Mapper?**
Let me check if the mapper tries to read these fields...

```typescript
// packages/domain/orders/providers/salesforce/mapper.ts
// The mapper DOES NOT try to read MNP or billing fields
// It only reads simple order fields
```

**Status:** ✅ These fields are only used for **writing** (order creation), not **reading** (order display)

---

## ✅ SAFE TO PROCEED - With Additions

### **Conclusion:**

1. ✅ All fields used for **reading** (display) exist in raw types
2. ❌ Fields used for **writing** (creation) are missing from raw types
3. ✅ We can safely remove field config for **reading/mapping**
4. ⚠️  We need to **ADD missing fields** to raw types for **writing**

### **Action Plan:**

1. **First:** Add missing fields to `SalesforceOrderRecord` schema
   - MNP fields (11 fields)
   - Billing address fields (5 fields)
   - lastAttemptAt field
   - addressChanged field

2. **Then:** Remove field config system
   - Update mappers to use direct access
   - Update query builders to use actual field names
   - Update order builder to use actual field names
   - Delete field config service
   - Delete field config interfaces

---

## Next Steps

Before proceeding with removal, I need to:

1. ✅ Update `SalesforceOrderRecord` schema with missing fields
2. ✅ Verify order creation still works
3. ✅ Then remove field config system

**Ready to proceed?** I'll first add the missing fields to the raw types.
