- Replace repetitive JSON marshalling with MarshalledTextResult helper - Replace repetitive HTTP error handling with new HandleHTTPError helper - Remove unused imports (encoding/json, io where not needed) - Fix error message formatting to follow Go conventions - Delete constants.go approach that increased duplication - Focus on structural patterns rather than string literals This addresses SonarQube high severity issues: - go:S1192 (String literals should not be duplicated) - go:S3776 (Cognitive Complexity of functions should not be too high) All tests pass and lint checks are clean.
