bookshop

A small Flask service for a bookshop: a catalogue with stock, a pricing

function and an order lifecycle. It is a benchmark fixture for AK-Bench, so two

things are deliberate:

• the money arithmetic is documented to the cent, because the benchmark tasks

are about arithmetic boundaries, not about guessing a currency policy;

• the test suite is narrow on purpose. The tasks hide the tests that cover the

boundaries, so an agent has to read and reason about the rules instead of

watching a red test.

Run the suite with pytest.
