One variant per TDS authentication mode the merged spec’s
components.securitySchemes documents (sqlAuth/windowsAuth/
azureADAuth — see docs/sqlserver-eda-openapi-pipeline/README.md’s
“OpenAPI mapping convention”). mcpify’s OpenAPI-auth-scheme classifier
only recognizes sqlAuth (http/basic -> mapped here as
SqlServer) and azureADAuth (oauth2 -> AzureAd) — windowsAuth
(http/negotiate) isn’t a scheme shape mcpify’s classifier knows, so
Windows was added by hand rather than generated.
