//! Equivalence tests for pattern validation and structure analysis
//!
//! These tests verify that validation and analysis functions in pattern-rs
//! work correctly with patterns generated by the gramref CLI tool.
//!
//! **Note**: Validation and analysis functions are NEW functionality in pattern-rs.
//! They do not exist in ../pattern-hs yet, so direct equivalence testing is not possible.
//! However, we can use the `gramref generate` command to create test patterns and then
//! validate/analyze them in pattern-rs to ensure our functions work correctly.
//!
//! **Important Distinction**:
//! - `../pattern-hs/libs/` = Haskell library reference implementation (source code to port)
//! - `gramref` = CLI tool for generating test patterns (testing utility)
