Thread To Decision helps land a sprawling chat thread on an actual decision through the summarize-and-fork move, the decider-and-deadline injection, and the recorded close that ends the forty-message orbit. Use it when asked why our threads never conclude, to get a decision out of a discussion, or to summarize where everyone landed. It produces a compressed thread summary with attributed positions, an isolated decision question, a structure injection, a closure message, and a durable decision record.
