```typescript
// STATUS_SCANNER -> ControlStatus
// APROVED -> VALIDATED
// JOINED -> ALREADY_USED
// UNSUSCRIBED -> CANCELLED
// REJECTED -> REJECTED
// UNKNOWN -> NOT_FOUND
// INVALID -> NOT_FOUND
// ENTRY_INCORRECT -> WRONG_ACCESS
```

--------------------------------

A helper function responsible for validating the structure of QR code data. This ensures that the scanned data conforms to the expected format before further processing.

```typescript
import { parseQrData } from './parseQrData.helper';

const qrData = '...'; // Scanned QR data
if (parseQrData(qrData)) {
  // Process valid QR data
}
```

--------------------------------

### Synchronization Hooks (TypeScript)

```

--------------------------------

### Tickets Sync Service Functions (TypeScript)

Source: https://context7_llms

Handles the synchronization of ticket data. It includes functions to fetch tickets from the server in a paginated manner and insert them into the local database.

```typescript
function getEventTickets(page: number) {
  // Fetch tickets with pagination
}

function insertTickets(tickets: Ticket[]) {
  // Insert tickets into local DB
}
```

--------------------------------

### Database Service - Table Definitions (TypeScript)

```typescript
interface Ticket {}
interface TicketInfo {}
interface Movement {}
interface Sector {}
interface StoredEvent {}
```

--------------------------------

### Scanner Mode vs. Verification Mode (TypeScript)

Source: https://context7_llms

Differentiates between the 'Scan Mode' and 'Verification Mode'. In Scan Mode, the entry is consumed, ticket status updated, and movement recorded. In Verification Mode, only validation occurs without consuming the entry or recording movement.

```typescript
const isVerifyMode = false; // Set to true for verification mode

if (!isVerifyMode) {
  // Burn entry
  // Update ticket status
  // Record successful movement
} else {
  // Only validate ticket
  // Do not burn entry
  // Do not update ticket status
  // Do not record movement
}
```

--------------------------------

### Sync Movements with Ticket Check Function (TypeScript)

Source: https://context7_llms

Performs a comprehensive synchronization process. It sends local movements, receives server movements, and verifies if an event has been cleared on the server. This is used for both manual and automatic synchronization.

```typescript
function syncMovementsWithTicketCheck() {
  // Implementation for full synchronization
}
```

--------------------------------

### TOTP Validation Helper (TypeScript)

Source: https://context7_llms

Handles the validation of Time-based One-Time Passwords (TOTP) for dynamic QR codes. This is essential for ensuring the security and validity of dynamically generated codes.

```typescript
import { Totp } from './Totp.helper';

const secret = '...'; // TOTP secret
const token = '...'; // User provided token
if (Totp.verify(token, secret)) {
  // Token is valid
}
```

--------------------------------

### Sync Movements Only Function (TypeScript)

Source: https://context7_llms

A function designed to send only movement data to the server. This is typically used during logout procedures or for cleaning up the local database.

```typescript
function syncMovementsOnly() {
  // Implementation to send only movements
}
```

--------------------------------

### Ticket Burning Logic

Source: https://context7_llms

Describes the process of 'burning' a ticket, which involves updating its status to REDEEMED. This action is conditional on not being in verification mode and is performed by the scanner.

```typescript
// Condition: !isVerifyMode
// If Scanner mode: Burn ticket (update status to REDEEMED)
// If Verify mode: Only validate, do not burn

// Updates when burning:
// ticketStatus -> REDEEMED
// controllerId -> ID of the controller that burned
// controlDatetime -> Date and time of burning
```

--------------------------------

### Sector Validation Logic (TypeScript)

Source: https://context7_llms

Implements the logic for validating allowed sectors during the scanning process. It checks if the sector of a scanned ticket is present in the list of allowed sectors for the current event. If not, it returns an error status and does not register a movement.

```typescript
const allowedSectorIds = [1, 2, 3]; // Example allowed sectors
const ticketSectorId = 4; // Sector ID from scanned ticket

if (!allowedSectorIds.includes(ticketSectorId)) {
  // return STATUS_SCANNER.ENTRY_INCORRECT
  // Do not register movement
}
```

--------------------------------

### Burn Time Validation Helper (TypeScript)

Source: https://context7_llms

Validates the 'burn time' or usage time for tickets. This helper function ensures that tickets are only used within their valid time window.

```typescript
import { validateBurnTime } from './validateBurnTime.helper';

const ticket = { validUntil: '...' }; // Ticket data
if (validateBurnTime(ticket)) {
  // Ticket is within valid time
}
```
