/**
 * POS decimal quantity REST schema relaxation.

 * @package WCPOS\WooCommercePOS
 */

namespace WCPOS\WooCommercePOS\Services;

/**
 * Relaxes integer-typed wc/v3 quantity schemas for POS requests when decimal
 * stock/cart quantities are enabled.
 *
 * The v2 write surface forwards mutation envelopes to the stock wc/v3
 * controllers (Write_Controller::dispatch_write), whose schemas type order
 * `line_items[].quantity` and variation `stock_quantity` as `integer` — a
 * POS push carrying 0.5 is rejected with rest_invalid_param before WooCommerce
 * ever sees it. The v1 surface relaxed these on its own controller subclasses
 * (V1\Orders_Controller / the products trait); the forwarded wc/v3 dispatch
 * needs the same relaxation applied to the registered endpoint args instead.
 *
 * Products' own `stock_quantity` is only relaxed where WC still hardcodes
 * `integer`: current WC keys that schema off wc_is_stock_amount_integer(), so
 * the existing woocommerce_stock_amount floatval swap (Products.php) already
 * yields `number` there and this filter is a no-op for it.
 *
 * Gated the same way as Stock_Validator: the hook is always registered, the
 * callback bails unless this is a POS request AND the setting is enabled — so
 * direct (non-POS) wc/v3 requests keep WooCommerce's strict schema.
