      x-apievangelist-note: >-
        This OpenAPI was derived MECHANICALLY from the AWS-published Smithy 2.0 service model
        (github.com/aws/api-models-aws, models/lex-models-v2/service/2020-08-07) — every path, method,
        operationId, parameter, schema and error code comes from that model. AWS publishes no OpenAPI
        of its own for Amazon Lex; the Smithy model is the authoritative first-party contract and this
        document is a faithful projection of it, not an independent description.
