The published changelog announces stored-answer comparisons, prompt editing without losing history, CSV exports and visibility into where a brand appears in an answer. These can be useful research features because they preserve more than a headline score. However, retaining old records is not enough by itself. The reader still needs to know whether two answers came from comparable prompts, settings and conditions.
When editing a prompt, record the reason and the date. A small wording change can alter the task substantially: adding a country, price ceiling or industry can change which products are relevant. Preserve the original baseline rather than presenting the entire history as one unchanged experiment. The convenience of editing in place should not erase the conceptual boundary between the old question and the new one.
Use answer differences to generate hypotheses. If a product disappears, inspect whether the answer became shorter, shifted categories, used different sources or changed its interpretation of the task. A disappearance does not automatically mean a competitor displaced you through better marketing. Likewise, an appearance does not prove a recent page update caused it. The history is evidence of a changed response; the explanation requires additional reasoning.
Export a sample early in the evaluation and see whether it contains enough information to remain useful outside the application. Can a colleague identify the prompt, time, model, market and source links? Are long answers preserved intelligibly? This matters for client reporting and for continuity if you later stop using the service. A research archive should remain understandable after the person who configured the dashboard has moved on to another project.
