//! Tests for [`role_auth`] and [`embedder_env_endpoint`] — the resolution the
//! daemon and the Python/Node bindings now share (#1886), where before only
//! the daemon read any of these variables at all.

/// Every variable [`embedder_env_endpoint`] reads, cleared so one test's
/// setup cannot leak into the next (tests run `--test-threads=1`, so the
