vpxtool 0.33.2

//! Parser regression tests pinned to real-shape score files in
//! `tests/fixtures/`. Each test maps a fixture to the source table whose
//! shape it captures; if a future parser change breaks a known table's
//! file shape this test fails loudly.
//!
//! Fixture data is anonymized (`AAA`/`BBB` or character-name defaults
//! from the source table) - the *layout* is what matters.
//!
//! Tests use only the public path-based API so they double as smoke
//! tests for the API surface. Edge-case / algorithmic behavior stays in
//! the unit-test modules next to the parsers.
