//! Rust Vault tests + cross-language parity.
//!
//! A parity test here writes a vault on the Rust side with fixed parameters,
//! then spawns `bun` to open it via a tiny TS helper script that reads a
//! known entry and prints it. A matching script does the reverse direction
//! (TS writes, Rust reads). If the argon2id + chacha20poly1305 byte
//! behaviour diverges, either side fails to decrypt.
