Fixed

Critical Security Issues

• InputValidator: Fixed email validation to reject domains without dots and corrected SQL injection sanitization output format
• SecurityManager: Resolved nested sensitive data redaction in audit logs and fixed XSS validation regex state pollution through proper lastIndex reset
• SecureLogger: Fixed debug logging configuration, URL sanitization with double-encoding issues, hash regex pattern matching, empty user ID handling, and circular reference handling
• CollectionManager: Implemented error message nesting prevention with root error message extraction

Test Infrastructure Issues

• Resolved all 67 initial test failures across 12 test files
• Fixed mock configuration issues for Express and QdrantClient
• Resolved memory system circular reference issues
• Fixed configuration schema validation for OAuth, URL, and JWT schemas
• Corrected EnvManager number parsing for tokenRefreshThreshold
• Fixed HTTP EndpointMetrics RPM calculation issues
• Resolved HTTP EndpointManager authentication middleware integration

Changed

Test Coverage Improvements
