//! Test mutation operation type dispatch and routing.
//!
//! This test verifies that:
//! 1. Mutation operations are correctly identified and routed to mutation handlers
//! 2. Query operations don't execute mutations
//! 3. Mutation/Query names are properly matched to schema definitions
//!
//! # Risk If Missing
//!
//! Without this test, mutations could be silently routed to query handlers,
//! or queries could be routed as mutations, leading to:
//! - Silent data corruption (mutations executing as queries)
//! - Incorrect resolver selection
//! - Type mismatches in responses
