+ * Unit tests for check-audit.mjs filter logic.
+ *
+ * Tests the four behavioral cases without spawning pnpm:
+ *  1. Unwaived High advisory → blocking (filter returns it)
+ *  2. Waived High advisory (GHSA in allowlist) → not blocking
+ *  3. Only moderate/low advisories → not blocking (advisory-only)
+ *  4. No advisories → not blocking
