Are these files visible to visitors?

Most visitors will not care about them, but they are public and useful for crawlers, search systems, AI tools and technical checks. Structured outputs such as schema, feeds and public JSON give search systems and AI tools a clearer path into the business information. In other words, the goal is to give the client a controlled first AI layer instead of leaving the whole topic vague and undefined. In the SupplyOnly.com model, the point is to make this useful rather than decorative: connect the answer to approved business facts, public Q&A, image context and the Own The Conversation fulfilment pathway. That gives a referrer or client a clearer reason to act without pretending that AI visibility is magic or guaranteed.
