Woo Guard

This runs an opinionated guard pass after code generation, catching the systematic failures AI agents make: order meta accessed through get_post_meta instead of CRUD (breaks on HPOS stores), checkout validation only in JavaScript, prices computed as floats, and hooks registered before checking if WooCommerce is even active. It enforces HPOS compatibility declarations, server-side validation for both legacy and Blocks checkout, and proper money handling through wc_format_decimal. Best used reactively after an agent writes payment gateways, checkout customizations, or anything touching wc_get_order, the cart session, or order meta. Ships with a self-check grep list and a concrete review checklist.
