> "The buyer wants to push the new Ralph Lauren collaboration this week. How do we change what the system recommends by Friday?"
If the answer involves editing prompts, redeploying, or filing an engineering ticket, the recommender is not a system. It is a demo.
If the answer is "the merchandising team edits a config file and it takes effect on the next customer query", the recommender is something that can survive contact with a real retail operation.
The system in question is the conversational AI your customers interact with — the shopping assistant, the product recommender, the commerce chat agent. The label changes. The control question does not.
