# LDPv2 - Complete Data Model (TypeScript)

This file contains all TypeScript interfaces and enums for the LDPv2 MVP.

## Enums

```typescript
// Application lifecycle status
export enum ApplicationStatus {
  IDEA = 'IDEA',
  IN_DEVELOPMENT = 'IN_DEVELOPMENT',
  IN_SERVICE = 'IN_SERVICE',
  MAINTENANCE = 'MAINTENANCE',
  DECOMMISSIONED = 'DECOMMISSIONED'
}

// External dependency types (Phase 2)
export enum ExternalDependencyType {
  WEB_SERVICE = 'WEB_SERVICE',
  DATABASE = 'DATABASE',
  CERTIFICATE = 'CERTIFICATE',
  NETWORK_FLOW = 'NETWORK_FLOW'
}

// Day of week for maintenance windows (Phase 2)
export enum DayOfWeek {
  MONDAY = 'MONDAY',
  TUESDAY = 'TUESDAY',
