//! Tests for installer audit functions, focusing on `audit_hermetic_parsed`
//! and related audit functionality.
//!
//! These tests exercise the audit pipeline through two paths:
//! 1. Directly constructing `InstallerSpec` from TOML strings
//! 2. Converting bash scripts via `convert_bash_to_installer` then auditing
