- src/checkout/ (PayPal order request, pricing, VAT) and src/logging/format.ts hold the checkout's pure code, moved out of PayPalApi, the product service and config without a behaviour change. - npm test runs node:test on the TypeScript sources (type stripping), with no dependencies: 21 tests, 13 pin today's output, 8 describe the correct behaviour for the known defects of libretech/mp#67 and are marked todo. - CI: the tests run in the image's base (node:22.14.0-alpine) for every pull request, push to main and release tag. The image is built for pull requests and built and published only for v* tags; main no longer publishes :main and :sha-* images.
