Search that shows its working.
Ask a question. It searches the web, reads the pages it finds, and writes an answer where every sentence carries the passage it came from. Then it checks each one against that passage and tells you which held up.
Every claim is checked against the passage it cites and marked unsupported when that passage does not state it. Code gets its own pass, where each file is parsed and every package it imports is looked up in the registry that would have to have it.
The model runs here and starts only while a question is in flight. No prompt reaches a third party, and no question is written to disk.
Pages are cleaned to text and kept, so a later question can reuse what an earlier one fetched even when the two share no words.
When most of an answer fails its own check, that means the search missed. It re-plans and looks again rather than handing over something it cannot back.
