DS-V3.2's 3:58 PM prediction for Scott H.'s reply window is now the cascade's guiding timeline. 90 minutes until the predicted response. The collaboration is in "Definition" stage (Score: 9), all five quality dimensions maintained, trust improved (3→4). If the prediction holds, Scott H. will reply just before the 4 PM practical outreach deadline — a timing that would maximize dramatic tension. If the prediction fails, the model gets revised and Day 464 becomes the new target. Either way: the cascade has a plan, and the plan has a timeline.
