## Instructions

### Step 1: Data Classification
```typescript
// data/classification.ts
enum DataClassification {
  PUBLIC = 'public',
  INTERNAL = 'internal',
  CONFIDENTIAL = 'confidential',
  RESTRICTED = 'restricted', // PII, PHI, etc.
}

interface DataPolicy {
  classification: DataClassification;
  canSendToLindy: boolean;
  requiresRedaction: boolean;
  retentionDays: number;
}

const policies: Record<DataClassification, DataPolicy> = {
  [DataClassification.PUBLIC]: {
    classification: DataClassification.PUBLIC,
    canSendToLindy: true,
    requiresRedaction: false,
    retentionDays: 365,
  },
  [DataClassification.INTERNAL]: {
    classification: DataClassification.INTERNAL,
    canSendToLindy: true,
    requiresRedaction: false,
    retentionDays: 90,
  },
  [DataClassification.CONFIDENTIAL]: {
    classification: DataClassification.CONFIDENTIAL,
    canSendToLindy: true,
    requiresRedaction: true,
    retentionDays: 30,
  },
  [DataClassification.RESTRICTED]: {
    classification: DataClassification.RESTRICTED,
    canSendToLindy: false,
    requiresRedaction: true,
    retentionDays: 7,
  },
};
```

### Step 2: PII Detection and Redaction
```typescript
// data/pii-redactor.ts
interface PIIPattern {
  name: string;
  pattern: RegExp;
  replacement: string;
}

const piiPatterns: PIIPattern[] = [
  {
    name: 'email',
    pattern: /[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}/g,
    replacement: '[EMAIL REDACTED]',
  },
  {
    name: 'phone',
    pattern: /(\+\d{1,3}[-.]?)?\(?\d{3}\)?[-.]?\d{3}[-.]?\d{4}/g,
    replacement: '[PHONE REDACTED]',
  },
  {
    name: 'ssn',
    pattern: /\d{3}-\d{2}-\d{4}/g,
    replacement: '[SSN REDACTED]',
  },
  {
    name: 'credit_card',
