#![allow(clippy::unwrap_used)] // Reason: test code, panics are acceptable

//! Test mutation argument binding and parameter handling.
//!
//! This test verifies that:
//! 1. Mutations with multiple arguments are structured correctly
//! 2. Argument types and values are preserved
//! 3. Nested input objects maintain structure
//! 4. Argument names are correctly mapped
//!
//! # Risk If Missing
//!
//! Without this test:
//! - Multi-argument mutations could lose or swap arguments
//! - Type information could be lost in parameter binding
//! - Arguments could be silently dropped
