nx_cms_ecommerce.nx -- CMS ECOMMERCE core (sovereign cart, exact money, inventory, order FSM). The WooCommerce class, made Nishi-native: ALL money is INTEGER CENTS (basis-point tax/discount) so there is ZERO floating-point rounding drift (the exceed angle -- float money is a real WooCommerce/Stripe pain), inventory is OVERSELL-PROOF (stock can never go negative, an over-quantity is refused not clamped), and the order lifecycle is an EXACT state machine. Pure deterministic integer logic -- the payment gateway is the only last-mile boundary; the commerce core is sovereign. Rates are the data-driven seam (rule 11). license_tier: ORIGINAL
