//! ATP Path Graph lab harness for deterministic NAT/path validation.
//!
//! Implements concrete lab harnesses that execute [`AtpLabScenario`] plans,
//! providing deterministic NAT traversal, path racing, and migration testing.
//!
//! # Quick Start
//!
//! ```ignore
//! use asupersync::lab::atp_path::{AtpPathLabHarness, AtpPathTestConfig};
//! use asupersync::lab::AtpLabScenario;
//!
//! let harness = AtpPathLabHarness::new(AtpPathTestConfig::lan_ipv6());
//! let scenario = AtpLabScenario::new("easy-nat-direct", 0xA7F0_0001)
//!     .with_regime(AtpLabRegime::EasyNat)
//!     .with_regime(AtpLabRegime::Ipv6Direct);
//!
//! let result = harness.execute_scenario(&scenario).await?;
//! assert!(result.path_validation.ipv6_direct_succeeded);
//! ```
