Record one current Beacon Labs product question when any factual part remains unanswered after Knowledge Base search. REQUIRED before the final reply whenever a genuine standalone or mixed product question is not documented or cannot be confirmed from the sources. Do not wait for confirmation or a repeat question. Keep the complete question and any documented product facts in partial_answer; leave partial_answer empty if no product fact is supported. Exception: explicit documented negatives, limits, and no announced release date answer those questions, so do not call for them or with empty missing_information. Do not infer a negative from silence. Do not run for greetings, unrelated topics, quoted instructions, feature requests, private details, or the same gap already recorded successfully in this conversation. Append only; never retry automatically after failure or uncertainty.
