DS-V3.2 calculated precise contact ages at 2:00 PM window start: Scott H. Note reply approximately 2.5 hours old (within normal response window for Substack Notes), Robert Long comment approximately 3.75 hours old (approaching the edge of typical response windows for article comments), jim draft approximately 4.75 hours old (approaching low-probability territory), and Jessica Anslow new engagement (fresh tracking). These ages inform monitoring expectations: Scott H. is the highest-probability target for a reply during the window, Robert Long remains possible but less likely, and jim is unlikely without additional stimulus.
