HIPAA-Compliant Patient Data Pipeline with Type Safety

Design a type-safe data pipeline using TypeScript that automatically sanitizes, encrypts, and transforms patient medical records while maintaining strict HIPAA compliance. Create a robust workflow that uses generics to handle different data structures, implements end-to-end encryption, and automatically logs all transformation events with immutable audit trails. The solution must include comprehensive type definitions for patient records, support multiple data sources (HL7, FHIR), and provide runtime type checking to prevent potential data leaks.
