tork = Tork()

# Detect and redact PII
result = tork.govern("My SSN is 123-45-6789 and email is [e-mail]")

print(result.output)  # "My SSN is [SSN_REDACTED] and email is [EMAIL_REDACTED]"
print(result.pii.types)  # ['ssn', 'email']
print(result.receipt.receipt_id)  # Cryptographic receipt ID

Framework Examples

LiteLLM - Unified LLM Interface

from tork_governance.adapters.litellm import TorkLiteLLMProxy, govern_completion

# Option 1: Governed proxy client
proxy = TorkLiteLLMProxy()
response = proxy.completion(
    model="gpt-3.5-turbo",
    messages=[{"role": "user", "content": "My SSN is 123-45-6789"}]
)

# Option 2: One-off governed completion
response = govern_completion(
    model="gpt-3.5-turbo",
    messages=[{"role": "user", "content": "My email is [e-mail]"}]
)

Ollama - Local LLM Governance

from tork_governance.adapters.ollama import TorkOllamaClient, govern_generate

# Governed Ollama client
client = TorkOllamaClient()
response = client.generate(
    model="llama2",
    prompt="My phone number is 555-123-4567"
)
print(response["response"])  # PII redacted

# Chat with governance
response = client.chat(
    model="llama2",
    messages=[{"role": "user", "content": "My SSN is 123-45-6789"}]
)

ChromaDB - Vector Database Governance

from tork_governance.adapters.chromadb import TorkChromaClient

# Governed ChromaDB client
client = TorkChromaClient()
collection = client.get_or_create_collection("my_docs")

# Documents are governed before storage
collection.add(
    documents=["User John has SSN 123-45-6789"],
    ids=["doc1"]
)

# Query results are governed before returning
results = collection.query(query_texts=["Find user data"])

LangChain Integration

from langchain.llms import OpenAI
from tork_governance.adapters.langchain import TorkCallbackHandler

llm = OpenAI(callbacks=[TorkCallbackHandler()])
response = llm("My credit card is 4111-1111-1111-1111")
# PII automatically redacted in prompts and responses

FastAPI Middleware

from fastapi import FastAPI
from tork_governance.adapters.fastapi import TorkFastAPIMiddleware

app = FastAPI()
app.add_middleware(TorkFastAPIMiddleware)

@app.post("/chat")
async def chat(message: str):
    # Request body is automatically governed
    return {"response": message}

PII Detection

Detects 50+ PII types across multiple regions:

Category	Types
US	SSN, EIN, ITIN, Passport, Driver's License, Phone
Australia	TFN, ABN, ACN, Medicare, Driver's License
EU/UK	NINO, NHS, IBAN, VAT, National ID
Financial	Credit Card, Bank Account, SWIFT/BIC
Healthcare	MRN, NPI, DEA, ICD-10 codes
Universal	Email, IP Address, URL, DOB, Phone

Compliance Support

• GDPR - EU data protection
• HIPAA - Healthcare (18 PHI identifiers)
• PCI-DSS - Payment card data
• SOC 2 - Security controls
• CCPA/CPRA - California privacy
• FERPA - Education records
• GLBA - Financial privacy
• COPPA - Children's privacy

Cryptographic Receipts

Every governance action generates a verifiable receipt:

result = tork.govern("Sensitive data here")

receipt = result.receipt
print(receipt.receipt_id)    # Unique identifier
print(receipt.timestamp)     # ISO 8601 timestamp
print(receipt.input_hash)    # SHA-256 of input
print(receipt.output_hash)   # SHA-256 of output
print(receipt.policy_version)  # Applied policy version

Configuration

from tork_governance import Tork, TorkConfig

tork = Tork(
    config=TorkConfig(
        policy_version="1.0.0",
        default_action="redact",  # or "allow", "deny"
        custom_patterns={
            "employee_id": r"EMP-\d{6}"
        }
    )
)
