A new public function is exported and never imported in the test file. Both guard clauses and the success return are unverified.\n- **processPayment rejects are untested** (Missing Negative-Path Tests). Both throw branches at lines 3 and 4 have no failing-input test. A regression that removes either guard would pass the suite.\n- **Happy path is narrow.** The one existing test covers only USD.
