Self-contained app-namespace artisan command (NEVER on production) that funds local imitation clients on a shared B2 supplier, disables DaData (region from tag), rebuilds the routing snapshot, then injects synthetic leads through the real RouteSupplierLeadJob so deals/charges/notifications appear for hands-on UI review. The lead payload encodes the supplier unique_key as a domain so RouteSupplierLeadJob re-resolves the real supplier (parseProjectField then resolveOrStub). Test asserts exit 0 + new deals.
