//! Explicit in-process participant testing support.
//!
//! This module is available only with the `test-harness` feature. It is not a
//! process launch protocol: tests supply a caller-owned bus and explicitly
//! drive the participant's lifecycle. Production participants enter through
//! [`crate::run`], which parses the supervised launch and opens its unique bus
//! owner.
