//! Cross-implementation compatibility tests.
//!
//! These tests verify that JSON payloads conforming to the BO4E standard can be
//! deserialized by rubo4e regardless of which BO4E implementation produced them.
//!
//! The payloads in `tests/compat/python/` represent the JSON format emitted by
//! the reference Python implementation (`bo4e/BO4E-python`).
//!
//! The payloads in `tests/compat/go/` represent the JSON format emitted by the
//! Go implementation (`Hochfrequenz/go-bo4e`).
//!
//! See `tests/compat/README.md` for how to regenerate these vectors.
