Start by reviewing the repository's OpenAPI 3.1 support and the linked JSON Schema tuple-validation reference; the issue names no file or test. Trace how array schema properties are handled, then determine where prefixItems support belongs and add coverage demonstrating the requested behavior. Done means schemas using prefixItems are supported.
