| 6 | + |
| 7 | +## Requirements Addressed |
| 8 | + |
| 9 | +### 1. Field Type Extensions (Priority: Medium) ✅ |
| 10 | + |
| 11 | +**Status:** COMPLETED |
| 12 | + |
| 13 | +The following modern field types have been added to improve UI component richness and competitiveness with Salesforce: |
| 14 | + |

| 37 | + - **Use Cases:** Warehouse tracking, delivery locations, store locators |
| 38 | + |
| 39 | +#### Previously Implemented (Confirmed Working) |
| 40 | + |
| 41 | +- ✅ `location` - GPS coordinates (original implementation) |
| 42 | +- ✅ `address` - Structured address fields |
| 43 | +- ✅ `richtext` - Rich text editor support |

| 48 | + |
| 49 | +### 2. Cross-Field Validation (Priority: High) ✅ |
| 50 | + |
| 51 | +**Status:** ALREADY IMPLEMENTED - Enhanced with Examples |
| 52 | + |
| 53 | +Cross-field validation was already fully implemented in `validation.zod.ts`. This implementation adds comprehensive documentation and examples. |
| 54 | + |
| 55 | +#### Features |
| 56 | + |
| 57 | +- **Cross-field dependencies** - Validate relationships between multiple fields |
| 58 | +- **Conditional validation** - Apply rules based on conditions |
| 59 | +- **Custom error messages** - Clear, actionable feedback |
| 60 | +- **Severity levels** - Error, warning, info |
| 61 | +- **Formula expressions** - Flexible condition syntax |
| 62 | + |
| 63 | +#### Example Validation Rules |
| 64 | + |
| 65 | +```typescript |
| 66 | +// Date range validation |
| 67 | +{ |
| 68 | + type: 'cross_field', |
| 69 | + condition: 'end_date > start_date', |
| 70 | + fields: ['start_date', 'end_date'], |
| 71 | + message: 'End date must be after start date', |
| 72 | +} |
| 73 | + |
| 74 | +// Capacity validation |
| 75 | +{ |
| 76 | + type: 'cross_field', |
| 77 | + condition: 'current_attendees <= max_capacity', |
| 78 | + fields: ['current_attendees', 'max_capacity'], |
| 79 | + message: 'Current attendees cannot exceed capacity', |
| 80 | +} |
| 81 | + |
| 82 | +// Discount validation |
| 83 | +{ |
| 84 | + type: 'cross_field', |
| 85 | + condition: 'discount_amount <= ticket_price', |
| 86 | + fields: ['discount_amount', 'ticket_price'], |
| 87 | + message: 'Discount cannot exceed ticket price', |
| 88 | +} |
| 89 | + |
| 90 | +// Conditional validation |
| 91 | +{ |
| 92 | + type: 'conditional', |
| 93 | + when: 'status = "published"', |
| 94 | + then: { |
| 95 | + type: 'script', |
| 96 | + condition: 'venue_location = null', |
| 97 | + message: 'Published events require venue location', |
| 98 | + }, |
| 99 | +} |
| 100 | +``` |
| 101 | + |
| 102 | +## Technical Implementation |
| 103 | + |
| 104 | +### Architecture |
