Domain Updater

Upload the production domain export (.csv or .zip). For each domain this verifies/corrects the mapped customer in as_domain via domains → clients → email → as_customers (falling back to customer 108 when no match resolves), sets registration = 1 and refreshes expiry — or adds the domain if it's missing entirely. It then makes sure each domain has an order on one of the core product IDs, inserting a default product 47 order if none exists. Safe to re-run.
