//! Shared helpers for integration tests.
//!
//! The 11-release `rac_basic_sample_family` corpus lives in
//! `phi-ag/rvt` — rvt-rs does not redistribute these Autodesk-owned
//! files (see SECURITY.md). Corpus location is resolvable by either:
//!
//!   - `RVT_SAMPLES_DIR` env var (used by CI when it checks out
//!     `phi-ag/rvt` into `_corpus/examples/Autodesk`), or
//!   - the default `../../samples/` path relative to the crate
//!     manifest (used by the local `rvt-recon-*` workspace layout).
