//! Helper binary for exercising shared custom CA environment handling in tests.
//!
//! The shared reqwest client honors `CODEX_CA_CERTIFICATE` and `SSL_CERT_FILE`, but those
//! environment variables are process-global and unsafe to mutate in parallel test execution. This
//! probe keeps the behavior under test while letting integration tests (`tests/ca_env.rs`) set
//! env vars per-process, proving:
//!
//! - env precedence is respected,
//! - multi-cert PEM bundles load,
//! - error messages guide users when CA files are invalid.
//!
//! The detailed explanation of what "hermetic" means here lives in `codex_client::custom_ca`.
//! This binary exists so the tests can exercise
//! [`codex_client::build_reqwest_client_for_subprocess_tests`] in a separate process without
//! duplicating client-construction logic.
