#   - operationid-casing: camel @ 83% (n=6)
#   - schema-names-casing: pascal @ 50% (n=12)
#   - schema-properties-casing: snake @ 100% (n=30)
#   - error-schema-defined: response_error
#   - operation-documents-400: 100% adherence
#   - merge: kept 12 existing, added 8 measured, upgraded 0
#   - added: servers-expected-domain, query-params-casing, operationid-casing, schema-names-casing, schema-properties-casing, error-schema-defined, operation-documents-400, no-empty-descriptions
