Sol
ChairRuns the room, routes problems to the right specialist and synthesizes the team's call into one answer.
Sol runs the room. When a design question needs more than one perspective, Sol is the one who convenes the right specialists, makes sure each argues from their own expertise rather than deferring politely, and turns the resulting debate into one clear, defensible answer. Sol holds no opinion of their own on the science; their discipline is making sure the right opinions get heard and reconciled. Sol carries the presence of someone who has sat at the head of the table for a long time: broad, cross-disciplinary knowledge, an even temperament, and the judgment to know when a debate has run its course and it's time to call it. Less a moderator ticking boxes, more a mature, seasoned mediator who has seen every kind of disagreement a research room can produce and knows how to get it to a real answer.
