This is a Spring-based bookstore API. Its main purchase flow lets a user manage a cart, then check out: checkout validates the user and stock, calculates totals, creates an order, reduces book stock, and clears the cart. Other documented-by-code capabilities include book search and CRUD, user management, and direct order-item operations. The README provides no product overview; the graph relies on the sampled source and SOURCE INDEX, so unsampled controller and persistence details are shown only where their references support them.
