+// - Records all authentication attempts and system access
+// - Provides query capabilities for audit trails
+// - Integrates with Prisma ORM for database operations
 //
 // RULES:
-// - All methods return Promises
-// - Input validation should be done at controller level
-// - Errors should be propagated to caller
+// - All methods return Promises for async operations
+// - Input validation must be done at controller level
+// - Errors should be propagated to caller with context
+// - Audit records should never be modified after creation
+// - Sensitive data should be hashed before logging
+// - Metadata should be stored as JSON for flexibility
