#   - servers-https-only: 100% of servers already https (error)
#   - servers-expected-domain: 1/1 servers on albertsons.com
#   - query-params-casing: snake @ 67% (n=9)
#   - operationid-casing: camel @ 100% (n=6)
#   - schema-names-casing: pascal @ 100% (n=10)
#   - schema-properties-casing: snake @ 67% (n=49)
#   - operation-security-required: 6/6 ops declare per-op security
#   - error-schema-defined: ErrorResponse
#   - operation-documents-401: 100% adherence
#   - pagination params observed: ['limit', 'offset']
#   - merge: kept 35 existing, added 7 measured, upgraded 0
#   - added: servers-expected-domain, query-params-casing, schema-names-casing, schema-properties-casing, operation-security-required, error-schema-defined, operation-documents-401
