#   - servers-https-only: 100% of servers already https (error)
#   - servers-expected-domain: 2/2 servers on concursolutions.com
#   - path-params-casing: camel @ 100% (n=7)
#   - operationid-casing: camel @ 100% (n=5)
#   - schema-names-casing: pascal @ 100% (n=6)
#   - schema-properties-casing: camel @ 84% (n=31)
#   - security: global (root) — NOT emitting operation-security-required
#   - merge: kept 11 existing, added 7 measured, upgraded 0
#   - added: servers-https-only, servers-expected-domain, operationid-casing, schema-names-casing, schema-properties-casing, security-schemes-defined, no-empty-descriptions
