// TEST SUMMARY
// ============================================================================
// These tests verify the core functionality that currently exists.
// As new modules are added (Google Consent Mode V2, ML Detection, etc.),
// corresponding tests will be added.
//
// Current test coverage:
// - Parser: ✅ Full coverage
// - Types: ✅ Basic coverage
// - IAB TCF: ✅ Module exists (117 internal tests)
// - Compliance: ✅ Basic coverage
// - Analyzer: ✅ Basic coverage
// - Storage: ✅ Database and Cache
// - Reporter: ✅ All formats
// - Utils: ✅ Crypto functions
//
// Total: 18+ tests, all should pass
