A record, with its edges showing.
This board records one set of Claude answers with web search enabled. It is a saved sample, not a live feed, a ranking, or a representative survey of every local business. Asking again can produce different names.
“No independent site found” means we could not find a domain the business itself controls. It may still appear on a directory, a social page, or a marketplace listing, and we may simply have missed it.
Our notes hold a thirty-sixth name, Hamilton Electric, which we left off the board because we could not confirm which business the answer meant. It is excluded from the 35 businesses and 27 sites counted here.
The pattern is an observation worth investigating. It does not establish why a business was named, prove that having a website caused inclusion, or predict how an assistant will answer about your business.
