+The release implements sophisticated replay protection that distinguishes between self-signed tokens (reusable for refresh flows) and external tokens (single-use only):
 
-- ✅ Self-signed tokens can be verified multiple times (essential for refresh flows and load balancer retries)
-- ✅ External tokens are tracked and blocked on replay attempts
-- ✅ Race condition mitigation with optimized check-then-set pattern
-- ✅ Separate tracking for reusable vs. single-use tokens
+- Self-signed tokens support multiple verification operations for refresh flows and load balancer retries

 **Consistent Validation Behavior**

   audience: "api-users",
-  strictValidation: true, // Now consistently enforces iss/aud validation
+  strictValidation: true, // Consistently enforces iss/aud validation
   enableJtiTracking: true, // Prevents replay attacks
 });
 
 // Self-signed tokens work correctly for refresh flows
 const token = validator.sign({ sub: "user-123" });
 validator.verify(token); // First verification
-validator.verify(token); // Still works! (refresh flow support)

 ### Path Traversal Defense
