A real case from the WixQA runs, where the agent records its own trails. Nothing is written while it searches.
ragtrail has no relevance threshold of its own. The agent decides how many searches to run and which sections its answer relies on. All 7 returned ids stay in the steps, but a later hit hands back only the 5 cited sections, and the answer is written again from their current text. Without a positive signal nothing is written; here the agent marked its own answer accepted.
