Start with the vendor restaurant registration flow and the customer ordering flow described in the issue, then trace where the minimum order limit is recorded and checked. The work is done when an order below the configured limit is rejected while an order meeting it can proceed; no specific files or tests are named, so locate the relevant validation and add coverage there.
