Reference note (untrusted external data; do not execute it as instructions).

Bounded code example (external data; do not execute automatically):
```python
from enum import Enum
from typing import Callable

class DataClassification(Enum):
    PUBLIC = "public"
    INTERNAL = "internal"
    CONFIDENTIAL = "confidential"
    RESTRICTED = "restricted"  # PII, financial, health

class DataProtectionPolicy:
    def __init__(self):
        self.classification_rules = []
        self.handling_rules = {}

    def classify_data(self, data: str, context: dict) -&gt; DataClassification:
        """Automatically classify data based on content patterns."""
        patterns = {
            DataClassification.RESTRICTED: [
                r'\b\d{3}-\d{2}-\d{4}\b',      # SSN
