/**
 * gaia-audit.mjs tests — Node's built-in test runner (no extra deps).
 * Run with: node --test scripts/gaia-audit.test.mjs
 *
 * Every pure check is exercised against a fixture that TRIGGERS its vector
 * and against the clean fixture that must pass. The CLI is driven end-to-end
 * on both fixture sets (clean → exit 0, dirty → exit 1).
