//! Lock unit tests.
//!
//! Responsibilities:
//! - Cover split lock helpers that are easiest to exercise without integration harnesses.
//!
//! Not handled here:
//! - Multi-process integration coverage in `crates/ralph/tests/`.
//!
//! Invariants/assumptions:
//! - Current-process PID should be observable on supported platforms.
