//! Shared helpers for integration tests.
//!
//! Each `tests/*.rs` integration test is its own binary, so each binary has
//! its own `OnceLock<GROK_HOME>`. The helpers below ensure the per-binary
//! initialization is identical: same env-var set, same isolation guarantees,
//! same reset between tests.
//!
//! Mirrors the GROK_HOME isolation pattern used in other integration tests.
//!
//! ## Usage
//!
//! ```ignore
//! mod common;
//! use common::{test_home, reset_home};
//!
//! #[tokio::test]
//! #[serial_test::serial]
//! async fn my_test() {
//! let _ = test_home(); // initializes GROK_HOME once per binary
//! reset_home(); // wipes state between tests
//! // ...
//! }
//! ```
#![allow(dead_code)] // each test binary uses a different subset
#[cfg(unix)]
