Watches the product catalog for the failure that emptied Everyday Deals on Sept 1, and shows the last check per store.
On Sept 1 a refresh wrote an empty promotion over every store and nobody knew until a customer noticed. Nothing was watching the data itself.
A guard that runs after every catalog refresh: it refuses wipes (a store going from products to zero), flags menu gaps, retailer-ID mismatches and config drift, and keeps a history per store. Verify Now runs the checks on demand.
