//! # Simulation & `Golden Master Tests` Definitions
//! **Crate**: `bistun-core`
//! **Ref**: `[LMS-TEST]`, `[011-LMS-DTO]`
//! **Domain**: `Tooling`
//! **Location**: `crates/bistun-core/src/simulation.rs`
//!
//! **Why**: Provides authoritative, pre-constructed models and `JSON` payloads for development and testing across the entire monorepo.
//! **Impact**: Eliminates `Mock Drift` across the ecosystem by providing a single source of truth for test data, ensuring UI and `Sidecar` components test against the exact same `Linguistic Metadata Schema`.
//!
//! ### Architectural Topology
//! * **Tier**: `0`
//! * **Dependencies**: `crate::manifest`, `crate::registry`, `crate::traits`, `hashbrown`
//! * **Consumers**: Development and Hermetic Testing Standard `LMS-TEST` environments across the monorepo
//! * **State Model**: `Stateless`
//! * **Design Patterns**: `Factory Pattern`
//!
//! ### Local Definitions
//! * **Golden Master Tests**: Authoritative, compilable rustdoc examples of a function's exact input and expected output, used for regression testing.
//! * **Mock Drift**: The phenomenon where test data becomes outdated compared to production schemas.
