Pages are fetched concurrently under a deadline, stripped of navigation and scripts, and returned with their titles and source URLs. Every page you asked for is accounted for: the ones that could not be read come back in pages_failed WITH the reason (403, timeout, paywall, no extractable text), because a thin web and a broken fetcher look identical otherwise. No model is called and nothing is summarised — you get the evidence, not an answer to trust. If the search finds nothing, or every page fails, you are NOT charged.",
