HIPAA-Compliant Patient Data Anonymization GraphQL Resolver

Design a type-safe GraphQL resolver in TypeScript that automatically anonymizes sensitive patient data while preserving referential integrity. Implement a robust type system using generics that strips out Personal Health Information (PHI) based on configurable anonymization rules. The solution must support multiple anonymization strategies (hash, truncate, mask) and provide compile-time type safety for different data models. Include comprehensive error handling for scenarios where anonymization cannot be completed and generate detailed audit logs for compliance tracking.
