dx-serializer 0.1.0

//! Property-based tests for format conversions
//!
//! **NOTE: These tests are currently disabled pending migration to V3 format.**
//! The V3 format uses a different section structure that requires updates to these tests.

// Tests disabled - the round-trip format changed with V3 migration
// The formatter outputs TOML-like sections but the parser expects different structure
